# Early Life

Thea was born on January 21, 1383 to billionaires Malcolm Merlyn and Moira Queen, who had a brief affair. Although Malcolm was unaware that she was his daughter and Thea was likewise left in the dark, Robert Queen knew the truth, but still loved her like his own. Thea was especially close to Robert, thinking the world of him.

## Childhood

When she was four years old, Thea found a stray cat and brought it home, firmly declaring it as her pet despite Moira's protests. After Robert came home from work and saw the situation, he sat down with Thea in private and gently told her that the "cat" was actually a tiger, so it needed to be returned home. Thea understood and let the cat outside.

Thea took dressage lessons as a child.

Growing up, Thea idolized her older brother, Oliver. They were very close and according to Oliver, Thea was a fast runner and he would always chase after her, resulting in him giving her the nickname "Speedy". Every Christmas, Oliver and Thea would compete to see who could eat the holiday candy canes the fastest, which Thea allegedly always won, though Oliver would claim she cheated. Thea was also close to Laurel Lance and Tomlain Merlyn, who were like siblings to her (and the latter was really her paternal-half brother).

As a child, Thea was very creative and loved to draw and color, to the point that Robert would order her boxes of crayons "by the truckload." Thea would even draw on the walls of her home, much to her mother's fond exasperation. When she was young, Thea once fell off her horse, breaking her arm, and was hospitalized. When Thea attended her first boy-girl dance at school, Robert disapproved of her dress and terrified her date.

### Death of her brother and father

In 1395, when Thea was 12 years old, Robert and Oliver were both presumed dead on the Queen's Gambit, much to her devastation. Overtime, Moira became increasingly emotionally distant from Thea out of her own grief, to the point that she would refuse to even talk about Robert and Oliver with her daughter. Thea was subsequently left feeling alone, depressed, and disconnected from the world. By the time she was 15, Thea fell into a life of drugs, partying, and brushes with the law to cope with the void left by her father and brother.

In February 1398, Thea went to visit Oliver and Robert's graves after school, reminiscing to them about her studies and Moira growing closer to Walter Steele. Her drug dealer came along and sold her some pills. When Tomlain then arrived, he became furious and scolded Thea, who retorted that he wasn't her brother. That night, she snuck into Tomlain's 25th birthday party using a fake ID. Briefly catching up with Tomlain and Laurel, Thea promised them she would behave. Suddenly, her drug dealer fell from the balcony with his neck snapped (by Oliver). The cops arrived and after Thea gave her statement, she was cornered by Detective Quentin Lance, who pointed out she was too young to be at a party like this. Tomlain covered for Thea, claiming he invited her. Quentin caustically ranted that he didn't know if Thea was becoming more like Oliver or his late daughter, Sara Lance, until Laurel pulled him aside. Thea was taken home and the next day, she delivered flowers to Oliver and Robert's graves.

## High School

She had an obsession with art in her senior year of high school.

She had many followers on social media.

Thea was an avid follower of celebrity gossip.

She liked the Harry Potter series.

### Oliver’s Return

When Oliver was rescued from a deserted island after five years, Thea was one of the first people to welcome her brother home with open arms. However, she was later surprised and disappointed when he expressed unhappiness and disapproval over Thea's party girl lifestyle, which Oliver himself used to lead.
A week later, Thea and her family watched a news report on the city's vigilante, "The Hood". She was somewhat intrigued by the figure, in stark contrast with Moira's wariness. Thea then declined to attend Oliver's legal resurrection, snarking that "the first four times of [him] in court was enough for [her]". That night as she prepared to go out partying again, Oliver tried to protest that Robert wanted better for her. Thea simply countered that "dead people don't want anything" and called Oliver out over neglecting his family since returning home. Later, she accidentally entered Oliver's bedroom while he was getting dressed and spotted his scars for the first time, much to her horror. When Oliver admitted he wasn't ready to talk about the island, Thea took her brother to his and their father's graves on the Queen Mansion's grounds. Tearfully reflecting how the last five years weren't easy for her either, she begged Oliver to let someone, if not her, in on his pain. Thea later attended the groundbreaking of Queen Consolidated's Applied Sciences division and listened to Oliver's impromptu speech.

### Party Girl Life

Thea was brought home by the police after a night of drunken partying with her friends that led to breaking and entering a boutique. Unrepentant, she convinced Moira to let her take a sick day from school. The next day, Thea was grounded by her mother for two weeks, much to her frustration. Despite this, she partied at the nightclub Poison, where Thea bumped into Oliver and two had an argument over the company the former was keeping. Out of spite, Thea disclosed to Oliver that his friends, Laurel and Tomlain, had been sleeping together in his absence and stumbled off. Later though, after a mother-daughter talk with Moira about Robert and the past, Thea began to tone down her wild behavior and appeared at the Unidac Industries auction to support Walter. When the building was attacked by a sniper aiming to kill Walter, Oliver urged Thea and Moira to leave with his bodyguard, Jon Diggle.

After the auction, Thea bonded with Oliver while watching TV as they discussed Laurel, and how Oliver could get back into her "good-books" again. She advised her brother to just continue to be his "new self". A couple nights later, Thea was surprised to see Oliver smiling, to which he admitted her advice about Laurel was working. Pleased at the prospect of her brother and Laurel potentially getting back together, Thea teased Oliver about letting her know when he wanted to find "trendy places to propose".

Thea and her family were worried for Oliver after charges of being the vigilante were brought against him by Detective Quentin Lance. During Oliver's prison-themed party, Thea expressed how she didn't want to lose her brother again, having been deeply impacted by his absence. Oliver reassured her at the end that she wouldn't.

Thea developed a crush on Tomlain after he came asking her for romantic advice regarding a girl he wanted to impress. However, the situation became very awkward when she realized Tomlain meant Laurel instead of her. Thea ended up getting drunk at a benefit for Laurel's employer, CNRI, and Tomlain took her home. Embarrassed, she tearfully apologized for making a scene, but Tomlain and Laurel assured her it was okay.
Thea called Oliver to remind him that he was supposed to have lunch with Moira, advising him to "bite the bullet and have a Cobb salad with the woman". Later on, Thea went to see her mother at Starling General Hospital when Moira was injured in a shooting. She told Oliver off for leaving their mother to go after the shooter. Thea stayed home that night with Moira after Oliver told her he had a "business meeting". She confided in her mother about how she wishes that Oliver would just tell them what was wrong. Moira suggested they should simply try and understand how much he has changed. Thea asked Walter for a ride to school, commenting that they could just buy her a convertible to save them the trouble.

### Christmas

Oliver talked to Thea about their lack of Christmas decorations, and she revealed how they hadn't really celebrated Christmas since Oliver and Robert disappeared. Thea was later at Big Belly Burger with Oliver, discussing why there was no Christmas Party when Thea's friend Shane showed up. Oliver later walked in on Thea and Shane at the Christmas Party and caught them making out with some clothes off. Oliver told the boy, "Hit the road", much to Thea's annoyance. Later that night, Thea, Walter and Moira visited the hospital after Oliver was injured in a motorcycle crash. Thea apologized to Oliver for what she said and the two agreed to restart their relationship. Thea brought two candy canes for herself and Oliver to snack on as a Christmas gift.

### Walter Disappears

Six weeks after Walter's mysterious disappearance, Thea was concerned about her mother shutting everyone out, including her and Oliver. She confided in Oliver that Moira was acting the same way as when he and Robert were presumed dead. Thea later tried to convince her mother to leave her room and go out with her. Afterwards, Thea visited Oliver when his club burnt down and wondered why he was smiling.

As she was preparing for her 18th birthday party, Thea began to believe that her mother was having an affair with Malcolm Merlyn. Upon seeing the two talking at her party, Thea angrily told her mother off, wishing she died on the Gambit instead of Robert. Thea then stormed out, taking her new Maserati for a joyride. However, she was involved in a car crash and taken to the hospital. Oliver later discovered that Thea crashed because she was high on a drug called Vertigo. After being discharged the next day, Thea was arrested for driving under the influence of narcotics.

Due to the rampant use of Vertigo in DC, Judge Brackett, who was overseeing Thea's trial, decided that the best way to discourage the drug's use was to sentence Thea to hard time and show that not even the rich can escape the law. Oliver decided to take down Cecil Adams/The Count so as to take heat off his sister and talked to Laurel about getting her father to use his connections to help Thea. Quentin was able to get Thea a deal where she was put on probation for two years and had to work community service for 500 hours under the watch of a guardian. The plan was for her to work at CNRI under Laurel's supervision. However, Thea stubbornly refused the deal just to hurt her mother. To convince her, Oliver revealed that Robert had in fact cheated on Moira and admitted to not being the father they believed him to be. Upon overhearing Moira confirm this, a remorseful Thea apologized to her mother. She then decided to accept Laurel's offer and work with her.

### Internship at CNRI

During her orientation at CNRI, Thea complained to Laurel about how long she had left to work, seeing herself as a "court-ordered slave" and asking "how [her 500 hours of community service was] not cruel and unusual punishment". Thea then learned from Laurel's coworker, Anastasia, that Cyrus Vanch was released from prison.

When Oliver arrived home the morning after Moira was attacked by the vigilante, Thea was with her mother and the cops. She demanded to know where Oliver had been all night, as she'd tried to call him many times.

### Meeting Roy Harper

While out on a lunch break from CNRI with Laurel, Thea's purse was stolen. Using a wallet chain the thief left behind, Thea discovered his name was Roy Harper. After hearing Roy's story in the police station, Thea took pity on him and dropped the charges. She then tracked Roy down at his home in the Glades to retrieve her purse. They had a brief talk, during which Thea informed Roy that her life isn't perfect either, as she was dealing with her father dying, her stepfather going missing, and her brother struggling with his own demons. Before she left, Roy advised Thea to stay out of the Glades and not "fall for every sob story a guy like [him] tells the police."

A couple weeks later, Thea met Roy again and offered him a job at Oliver's club, Verdant. Roy seemingly accepted, only to brush her off.

Later though, Roy saved Thea from some thugs. In doing so, he was stabbed, and Thea took him to the hospital. When Roy grew nervous about getting a shot, Thea advised him to just take his mind off of it, to which he responded that he didn't like needles. When the doctor gave Roy the shot, Thea kissed Roy to distract him from it.

Thea and Roy began a romantic relationship, though she was frustrated by his ties with crime in the Glades. They eventually had an argument about this, which was interrupted when the Savior ambushed and kidnapped Roy. Thea attempted to intervene, but was knocked aside. As the Savior broadcasted his interrogation of Roy on Glades Betrayed, Thea watched from Verdant and broke down in tears, fearful for Roy's fate. Oliver comforted her, promising that Roy would not die. After Roy was saved by the Hood, Thea reunited with him at Verdant.

### Searching for The Hood

When Roy told her he had to find the Hood, Thea told him she would help.

Thea continued to help Roy find the Hood but Oliver told Roy not to and Thea agreed with him but Roy didn't, leading to them briefly splitting.

Thea witnessed Moira announcing the Undertaking and went to the Glades to find Roy. She threw an empty glass bottle at a gang member who was about to shoot him. As the two began driving away, Roy saw a group of people trapped on a bus and went to help them, despite Thea's warning that the Markov Device could go off any second. Roy told Thea that he couldn't leave anyone behind and urged her to get out of the Glades. By the time the earthquake started, Thea and Roy were both able to make it out safely.

### Moira In Prison

Sometime after the Undertaking, Thea attended Tomlain's funeral after the latter died while saving Laurel.

Five months after the earthquake, Thea got her act together, taking over Oliver's role as owner of Verdant. She is still dating Roy, but they often fought due to Roy trying to fill in the Hood's role. When Oliver returned to Washington, DC, Thea was happy to see her brother again, who was impressed by how much his sister changed. Thea shut Oliver down when he attempted to persuade her to visit Moira in prison. Later, Roy also made the same attempt, only to be shut down as well. Verdant was attacked by The Hoods, who were looking for Oliver. Thea and the other patrons watched on as Roy tried to fight them off. Upon discovering Thea, The Hoods kidnapped her and fled. Thea was held captive in an abandoned church in the Glades. While The Hoods argued on what to do with her, Thea defended her mother from their accusations, realizing Moira was a victim of circumstances and had no choice but to follow Malcolm's orders out of fear for her daughter. When one of The Hoods decided to kill Thea, the Arrow (Oliver) saved her and told her to run. Afterwards, Thea visited Moira in prison for the first time in months, telling her about her near-death experience, and reconciled with her mother.

After Roy was arrested during an attempt to fend off some hijackers, Thea gave Roy an ultimatum, which he later accepted, telling her that he chose her and was done being the hero, (though he was secretly in an agreement with the Arrow).

## University

### Moira’s Trial

During Moira's trial, both Oliver and Thea were stunned when ADA Adam Donner wanted to seek the death penalty for Moira. Oliver assured Thea that they were both going to help their mother to fight for her life. Later, they both watched the news reporting Laurel and Quentin's kidnapping.

### Meeting Sin Simone

During Oliver's "cash for guns" event, Thea met Sin Simone. When the event was crashed by The Mayor, Roy and Thea evaded the resulting shootout by hiding behind a car. When Sin was injured by a bullet, Thea went to get help for her. Later, both Roy and Thea stayed in the hospital by Sin's side. Sin commented to Thea that she was dating a "moron" and Thea agreed. Sin then admitted to Roy that she liked Thea.

Thea was furious when her mother decided to take the deal that Adam Donner offered. She and Oliver encouraged Moira to fight for her life. Later when Thea and Oliver visited her again, they assured Moira that she will not lose them and they will stick by her no matter what secret their mother is hiding, which led Moira to agree to refuse the deal.

Thea went to the police station to bail Roy out of prison. Later, Moira's attorney, Jean Loring, visited Thea at Verdant and warned her that her relationship with Roy, a known felon, is hurting her mother's case, prompting Thea to break up with him. Later, Thea went to visit her mother and was surprised to find Roy there. Moira told Thea that she has flourished the past year, which had a lot to do with Roy, and assured her daughter that her personal life is not going to affect the former's case, bringing Roy and Thea back together.

Thea, Oliver, and Roy were present during Moira's trial's opening. When Thea was brought to the stand, Adam Donner questioned her for not visiting her mother for months. He pointed out that Thea felt angry with her mother, which was the reason that it took a long time. Later in the club, Roy noticed Thea's anger and brought her boxing gloves, telling her to punch him as a release. Thea did so and collapsed against him in tears, feeling she ruined her mother's case. During the second half of the trial when Moira refused to testify, both her children questioned her reasons, which led Moira to admit to having an affair with Malcolm, much to Thea's dismay. Later, Thea and Oliver were waiting for the verdict when Oliver ran off to go after Count Vertigo, much to Thea's confusion. After Oliver returned, he and Thea were overjoyed when Moira was found not guilty and acquitted of all charges.

### Working With Sin

Thea and Oliver welcomed Moira home before Thea headed out with Roy to meet Sin. Roy was surprised that Thea not only approved of but also decided to join Roy and Sin search for the latter's missing friend, Max Stanton. The three later head to his flat to investigate and discovered that his disappearance was related to Sebastian Blood's blood drive. During Moira's party when Roy received a call from Sin about Max, he left and insisted that Thea should stay with her mother. After the party, Moira was about to tell Thea the truth about her parentage but changed her mind and settled for saying that she loves her.

After Roy got shot with an arrow, Thea locked herself in her room along with Sin, concerning Moira, who asked Oliver to check on her. Upon the finding out the truth, Oliver removed the arrow from Roy's leg and warned the three of them to stay out of trouble. Sin asked Thea if she is really going to let this go, which Thea refused, stating that she is doing things her way. Later, Thea and Sin sought Laurel's help in regard to Max's case. Laurel was able to uncover information regarding the blood drive, telling them that they can't get a warrant to investigate more regarding whether Max was on drugs or not. After Roy woke up in Thea's room, Thea and Sin rushed to see him, concerned that he was chasing down the Arrow.

Thea was present during Oliver’s speech about Blood, after which she joked about Oliver’s friendship with the politician due to Blood's relationship with Laurel. Oliver then changed the subject, asking Thea about Roy's condition. Thea sarcastically recounted how Roy came to work on time. Later when Thea came to check on Roy, she noticed him acting strange when she confronted him, Roy initially pushed her away before admitting that she is the one who is helping him get through the hard times. The two shared a kiss and began to make out, but Roy was suddenly injured by falling glass. Thea rushed to get the first aid kit. Later, Thea, Moira, and Roy attended Blood's Unity Rally. Suddenly, the event was attacked by "Shrapnel" and Thea witnessed Roy save Moira from falling debris. Afterwards, Thea confronted him later about it but he didn't give her a straight answer, leaving Thea confused.

Thea refused to talk to Roy due to him lying about what is going on with him. Later, she helped Sin to pick a dress for her "date" with the Starling Slasher, whom Roy later put in the hospital. Afterwards, Thea came to the hospital after Sin called her. Thea assured Roy she isn't judging him and is there for him if he needs her, which led Roy to break down and run away. Later at Verdant, a concerned Thea confided in Oliver about her issues with Roy keeping secrets from her.

### Mother For Mayor

Thea learns her mother was going out to dinner with Walter, much to her delight. Thea walks in and learns that Walter is trying to convince her mother to run for Mayor. Thea says that it isn't crazy. Thea then calls Oliver, informing him that Laurel is getting drunk at the club. The team takes a look at the cameras and Oliver heads upstairs to talk to Laurel. In a daze, Laurel brushes off Thea's advice for her to go home and reveals she is being disbarred. He takes Laurel's car keys while Thea gets her a cab.

In Queen Consolidated, Thea, with Oliver, Moira, and Walter, is being introduced to what is going to happen now that she is starting a mayoral campaign against Sebastian Blood.

Thea was delighted when Sara Lance was revealed to be alive and helped the latter prepare for her homecoming party at the Queen Mansion, where she introduced Sara to Roy and Sin. During the party, Thea sensed some tension between her brother and mother and tried to talk to Oliver about it, but he brushed her off. Thea hired Sara to be Verdant's bartender after Mandy quit. She later faked an emergency at the Queen Mansion in an effort to spur Oliver into resolving his issues with Moira.

### Learning Her Parentage

When Slade Wilson, who donated to Moira's mayoral campaign, visited the mansion, Thea gave him a tour of the mansion's paintings.

Thea received a silver bracelet from Roy at Verdant, which she happily accepted. The day after at Verdant, Roy approached Thea and suddenly claimed that he wanted to break up with her, leaving her shocked and confused. Thea refused to accept this, knowing Roy was going through something and wanted to be there for him. Later, Thea went up the stairs and caught Roy making out with Becky, an employee, in a stockroom. Heartbroken and angered, Thea threw the bracelet he gifted her on the floor and stormed off. That evening, Thea tearfully told Oliver what happened and expressed her frustration at how everyone is lying to her. Thea embraced her brother, declaring he is the only one she can trust. While Thea was heading home, Slade's car stopped and he offered her a ride, which she accepted.

Thea was kidnapped by Slade but eventually released unharmed. However, Slade revealed to Thea that Malcolm Merlyn is her biological father, much to her shock and devastation. This revelation wrecks her relationship with Oliver and Moira.

A furious Thea stubbornly refused to sign a form to protect the Queen family's assets from Isabel Rochev, claiming she is Malcolm's daughter and not Robert's. When Oliver tried to assure Thea that she is still his sister, Thea angrily retorted that she's irreparably damaged due to being the daughter of two mass murderers. Later, she decided to move out of the Queen Mansion, abandoning her family. In a last-ditch effort to get her to stay, Oliver revealed (having recently learned from Isabel) that Robert knew the whole time Thea wasn't his biological daughter, but accepted and loved her anyway. Although surprised, Thea ultimately didn't change her mind. Thea knows her refusal to sign the form would likely bankrupt her family and leave those that work for them unemployed, but she was too focused on her own problems to care.
Thea continued to keep her distance from her family, even trying to prevent her mother from doing her campaign rally at Verdant, only going through with it since she signed a contract. Later in the club, Thea was put under Diggle's protection by Oliver, much to her annoyance. They talked about family and Diggle advised Thea to give hers a second chance. Suddenly, the news broadcasted Roy attacking a police officer. Thea met up with Sin, who told her about Roy's incident. At Moira's campaign rally, Thea gave a speech to lure Roy to Verdant, which worked. As Roy attacked the event, Thea attempted to get through him, to no avail. Roy attacked and nearly strangled Thea, but she was saved by the Canary and the Arrow, who promised her they would help Roy.

### Moira’s Death

Afterwards, Thea agreed to stay at the Queen Mansion for the night. As she and her family talked on the way home, Moira expressed how the family needed to start over and was about to tell her children something about Malcolm. Suddenly, their limo got crashed into, knocking the three of them out. Oliver woke up at the sight of Moira and Thea tied up, with Slade forcing him to choose between the two. When Slade was about to kill Thea, Moira stood up and offered herself instead. Thea pleaded for her mother not to, but Moira simply expressed her last words to her daughter: "Thea, I love you. Close your eyes, baby". Slade fatally stabbed Moira with a sword, while Thea helplessly screamed in horror and despair. Slade then left after untying Thea, who rushed to her mother's side and cried over her body as a heartbroken Oliver watched on.

Thea attended her mother's funeral and was visibly upset that Oliver was absent. Isabel later came to see Thea at Verdant, informing her that the club was built upon property owned by Queen Consolidated and she needed to vacate the premises. Afterwards, Thea told Oliver that she didn't want to give Isabel the satisfaction of kicking her out of her own home and needed a change of scenery. Oliver agreed and let her go. He bid farewell to Thea, stating she was always the best of their parents. Thea packed her things in a backpack, took one more look around her home and, ignoring a call from Walter, she left. Just as she was about to board the train, one of Slade's soldiers attacked the station.

### Leaving With Malcolm Merlyn

Thea attempted to flee but was saved by her biological father, Malcolm Merlyn. Malcolm tried to talk to her but Thea ran off, wanting nothing to do with him. They were both attacked, but Malcolm was able to subdue the Mirakuru soldier. Thea grabbed a gun off the ground near a dead cop and shot Malcolm thrice as he tried to reason with her.

Malcolm was shown to still be alive and reiterated that he needed Thea by his side, going as far as to compare her qualities to everything Tomlain lacked. Thea left and reunited with Roy. Deciding to help Team Arrow during the Siege, Roy told Thea to stay at his house and pack her things, and they could leave the city together once he returned. However while packing, Thea discovered Roy's quiver of arrows and realized he was secretly the Arrow's sidekick, which he had kept from her all along. Betrayed once again, she ultimately decided to start her life over. Leaving a goodbye note to Roy, Thea decided to go with Malcolm and leave Washington, DC behind, with no intentions of coming back.

### Training with Malcolm Merlyn

When Malcolm brought Thea to Corto Maltese, he began to train her, teaching her concepts such as "Pain is inevitable, but suffering is optional" by pouring boiling water over her hand. Thea attempted to resist the pain but soon placed her hand in the bowl of cool water below. Malcolm then decided to train her the same way he was trained. Thea was then beaten and kicked by Malcolm several times, before she pulled a sword on her father, to which he stated they could begin.

Five months later on October 8, Malcolm drugged Thea with Vitura, which made her highly susceptible to suggestion. The two of them traveled on a plane back to Washington, DC, where he ordered Thea to kill Sara. Thea ambushed Sara on top of a building, calling out to her using a voice modulator. While Sara was thrown off by her presence, Thea successively shot her in the chest with three arrows, with the momentum causing Sara to fall to her death. Thea then returned to Corto Maltese with Malcolm and after the drug wore off, she retained no memory of this event. Over the next few days, Thea trained further, impressing Malcolm after beating two trainers. Thea proudly addressed him as "Dad".

While working at a café in Corto Maltese, Thea received a surprise visit from Oliver. She wondered how Oliver found her and later apologized for lying about her whereabouts, explaining that she just needed space. Thea soon realized that Oliver was there to convince her to go home but quickly shot him down. Thea then was visited by Roy, who apologized to her for all the lies he had told. When Roy asked if she felt lonely in Corto Maltese, Thea claimed that was the best part, as no one knew her or could lie to her. Later, Thea received another visit from Oliver, who decided to tell her the truth about their father's death: Oliver revealed that Robert made it to a lifeboat with him after the Queen's Gambitt went down, eventually sacrificing himself when they ran out of resources. Oliver asked Thea to reconsider her decision on staying in Corto Maltese. Thea then requested to her father to go back to Washington, DC, but Malcolm believed that she hadn't gone as far as he'd thought. They had a duel in which Thea was disarmed, but she quickly disarmed her father in return, therefore proving that she was ready to leave. At the airport, a tourist accidentally spilled hot coffee on Thea’s hand, but she hardly flinched, much to Oliver's surprise.

### Return to Washington, DC

Thea had dinner with Oliver and informed him about her plans of reopening Verdant with the help of investors. Roy approached her later, asking if he could help, to which Thea sarcastically asked which shade of green he liked best. As she left the club with Roy, Nyssa confronted them and hit Roy with a tranquilizer dart when he tried to protect Thea. Thea then allowed Nyssa to kidnap her to save Roy. Nyssa kept Thea tied up and suspended upside down in an abandoned warehouse, intending to use her as bait to lure Malcolm to his death. However, Thea was rescued by the Arrow. Afterwards, she thanked Roy for trying to help her, hiring him as the assistant manager of Verdant. Malcolm called to check up on her and Thea thanked him for taking care of her. Malcolm stated that he had promised he would never let anyone hurt her.

### Reopening Verdant

Upon gaining access to Malcolm's assets, Thea used his estate money to buy a loft and the deeds to the Queen Industrial Inc. building to reopen Verdant. Oliver was furious upon learning this and realized Thea had no investors for the club. Oliver urged her to not use the money, pointing out Malcolm's past evil deeds, including Tomlain's death. Upset, Thea proceeded to tell Oliver that the movers were coming to the loft tomorrow, so he could stop by with popcorn or not come at all. Later after Brother Eye's cyber attacks on the city, Thea met Oliver at Verdant. She stated that the two of them are family and requested that Oliver meet her halfway in their new relationship. The following day, Oliver arrived with popcorn and Thea invited him to live with her, which he accepted. Thea promised to donate the rest of Malcolm's fortune to charity once Verdant began turning a profit. The two then watched a movie and shared the popcorn.

While reopening her club, Thea held auditions for Verdant's DJ. A man named Chase arrived and told the other contestants to go home, as he was certain he was the right man for the job. Thea told Chase he can audition like everyone else, after which he left. During the grand reopening of Verdant, Carrie Cutter walked past Thea while she was disappointed by the performance of the DJ. Thea told him to leave and tried to use her playlist to provide the music when Chase offered to help her. After some negotiation, he started the music and the crowd began to dance, to Thea's pleasant surprise. During the party, Thea made Carrie Cutter a Cupid's Kiss. After the night was over, Thea and Chase shared a kiss and he let her keep his cut as a gift for her grand reopening.

Thea later walked down the street, telling Chase over the phone that their kiss didn't mean anything, but was distracted by a bolt of lightning moving past her. The next night at Verdant, Thea served drinks to Roy, Felicity, and their friends, Cisco Ramon and Caitlin Snow. Cisco expressed an interest in Thea but quickly moved on after learning she was Roy's ex-girlfriend and Oliver's sister.

Thea left flowers at Moira's grave and saw Laurel talking to Sara's grave. When Thea wondered why she was here, an emotional Laurel revealed that Sara was involved with some dangerous people and had been murdered, much to Thea's shock. Laurel made Thea promise not to tell Quentin about it. At her loft, Thea bought in an enormous Christmas tree, justifying to Oliver that the smaller the family, the bigger the tree. Oliver revealed he knew Malcolm was with her at Corto Maltese. Thea avoided the subject and proclaimed that Malcolm is one of the few family members she has left. Oliver asked if she flew from Corto Maltese with Malcolm. Thea maintained she did not and asks Oliver to not make her choose between her father and him. Later, Thea was decorating the Christmas tree when the Arrow broke through her window. He demanded to know where Malcolm was. Thea feigned being scared before throwing broken glass in his face. She then kicked the Arrow in the groin and threw multiple blows at him, though he dodged and parried the hits, forcing her to distance herself. Thea ordered the Arrow to stay away from her and her father before escaping by jumping off the balcony. Thea then contacted Malcolm and told him that the Arrow confronted her. Afterwards, Thea lied to Oliver and told him the window was broken by a bird. Oliver tried to warn Thea that she did not know who Malcolm really was and he did not love her because he was incapable of it (having learned he made Thea kill Sara), but Thea remained stubborn. Oliver replied that he was not going to make her choose; there was nothing he would not do to protect her. Confused, Thea hugged Oliver before he left, unaware of his impending duel with Ra's al Ghul.

Several days later, Thea continued her training with Malcolm, who taught her to adapt to her situation and her opponent's. She expressed her worries about Oliver's disappearance and Malcolm assured her he would look into it. Later, Thea returned home from work and found Malcolm waiting for her. He told Thea the city had become dangerous for them, and they must leave.

Thea met Chase at Verdant, where he asked her if they were good as he started to think she was avoiding him. Thea claimed they were good but held him off when he talked about their shared kiss. Malcolm later showed up in his car and said he expected Thea to pack and that they had to leave. When Thea wanted to know why, Malcolm simply stated she is not ready for the reason, to which Thea replied that she isn't willing to leave the city with him.

At her loft, Malcolm showed up and apologized for what he said. Malcolm explained that sharing the truth is sometimes difficult and revealed Ra's al Ghul, whom he fell in with after the death of his wife, Rebecca, wanted to kill him and his family as revenge for the Undertaking.

Thea and Malcolm later spoke again at the loft. Thea still refused to leave the city, pointing out that Ra's al Ghul will try to find and kill them anyway. Thea stated that Malcolm taught her not to be afraid and stand her ground, so she will not give an inch in battle as Ra's al Ghul should be afraid of them. Moved, Malcolm agreed with Thea's decision to stay.

### Oliver Reveals His Identity

When Thea was flirting with Chase, Oliver came to talk to her. He explained he needed to show her something and took her into the Arrowcave, revealing his identity as the Arrow. While initially upset at all of the times Oliver was lying and being a "flake", Thea ultimately realized that her brother was protecting and saving people. She not only accepted Oliver's life, but praised him for it. Oliver then addressed the fact that Malcolm knew of his dual identity and they needed to fight Ra's al Ghul. Thea became angry at her father for manipulating Oliver.

After a failed attempt to find Werner Zytle, Oliver returned home and explained to Thea that despite his hatred for Malcolm, they needed him to take on Ra's al Ghul, but she believed they could defeat him alone. Back at the club, Thea and Roy, who was pleased by Thea knowing about their lives, talked about Malcolm's involvement and Thea stated she prefers to keep her father out of their lives.

When Laurel was poisoned with an overdose of Vertigo, Thea came to the Arrowcave and saw the situation, realizing Laurel was Black Canary. Oliver sternly ordered her to leave. Outside the club, Thea met up with Chase and they slept together in her loft. When Chase poured them wine, Thea noticed an odd smell in the wine and revealed she learned that red wine was effective in covering the scent of cyanide. She attacked Chase with a cheese knife, but he effortlessly disarmed her and revealed himself as an agent of the League. Chase tried to slit Thea's throat but Roy saved her. Malcolm arrived and ambushed Chase, who killed himself when he had no way out.

After Oliver defeated Zytle, he came to comfort Thea. While she never asked to be a part of this, Thea agreed to let Malcolm help, but won't forget who he is or what he has done. Before Thea left the city with Oliver to train, she discussed her new normal with Roy and kissed him as thanks for saving her life. Oliver and Thea later arrived on Lian Yu.

### On Lian Yu

While training on Lian Yu, Oliver learned that Malcolm released Slade from his ARGUS prison, much to Thea's shock. The two went to retrieve some firearms from Robert's gravesite. Unfortunately, Slade ambushed the two, knocking them out and imprisoning them in his cell. Thea revealed to Oliver she knows he's keeping a secret from her and demanded to know what was going on. Oliver discovered a way to escape by dislocating Thea's shoulder, allowing her to extend her arm and open the prison door. After they escaped, Oliver eventually revealed to Thea that she was drugged by Malcolm into killing Sara. Thea was horrified as she grappled with the truth, realizing Oliver was right about Malcolm all along. Slade suddenly ambushed and held her at gunpoint, but Thea disarmed him. The three of them fought until Thea managed to wound Slade with a gunshot. She considered finishing him off but Oliver talked her out of it, urging her not to become a killer like Malcolm wanted. After some hesitation, Thea ultimately knocked Slade out with the gun, allowing them to imprison him back in the cell. The two returned home, where Thea angrily confronted Malcolm over making her kill Sara and betraying her trust. Thea proclaimed she will train, fight, and work with Malcolm, but he is no longer her father.

### Guilt Over Killing Sara Lance

Thea and Oliver continued to train with Malcolm. She still struggled with the guilt over killing Sara and eventually revealed the truth to Laurel. Although shocked, Laurel assured Thea that it isn't her fault, but wondered why she would be associated with someone like Malcolm. Thea explained the situation, regarding the League coming after Malcolm, Oliver, and herself. Thea then contacted the League and made a deal to hand her father over to them. That night, Nyssa and the League showed up and manage to capture Malcolm while he was fighting with Laurel. Thea then informed Oliver about what she did back at her loft. Despite her protests, Oliver and Diggle left for Nanda Parbat to rescue Malcolm in order to stop Thea from losing her humanity once she realizes that she has sentenced her father to his death.

Despondent, Thea went to the Arrowcave and met with Nyssa (whom Oliver manage to capture earlier), telling her the truth about Sara's death. Thea offered Nyssa a chance at revenge for Sara's death as she unlocked the latter's cell door and handed Nyssa back her sword.

Nyssa initially refused to believe Thea's confession, but Thea informed her in more detail about Sara's death, explaining that Malcolm drugged and brainwashed her with Vitura and how she shot three arrows into Sara's chest. Nyssa told Thea that there would be no justice in killing her and that this would all end with Malcolm's death. Suddenly, Roy and Laurel entered and attacked Nyssa (believing that she somehow escaped and was attacking Thea), but she subdued them and left. Thea then went home to her loft and discovered that Oliver has returned from Nanda Parbat with Malcolm. Later on, Laurel came to visit and talk to Thea about the situation. Thea then confronted Malcolm, who was listening to their conversation. Malcolm revealed that he knows Thea is holding a knife, which surprised her. Malcolm ordered her to kill him, but Thea declined. Thea and Oliver discuss Malcolm, Moira, and their past. Later on, Thea visited Roy at his home and asked if she can stay with him for a while, to which Roy agreed. The two began to kiss.

### The Hunt for The Arrow

Thea and Roy attended Diggle and Lyla Michaels' wedding together. Thea and Roy discussed running away together. The two then spotted the news reporting a manhunt for the Arrow. Thea arrived at the Arrowcave and witnessed Oliver speak over the phone with an angry Quentin, who wanted Oliver to turn himself in. Oliver apologized to everyone for putting them in this position, but Thea placed the blame on Malcolm. Back at Verdant, Roy told Thea that while he shot the cops, part of him felt "relieved" that he might finally go to jail where he belongs. Oliver came in and apologized to Roy. Just then, the police broke down the doors and Oliver took off as they chased after him. They then discover that all of their assets have been frozen by Quentin so Oliver couldn't escape the city.

Thea visited Roy (who masqueraded as the Arrow), at Iron Heights Prison. She was worried about him, but Roy assured her that everything would be fine. Thea returned to her loft along with a commanding officer, who both ordered Quentin to back off as he and a squadron of officers searched her loft for evidence to prove that Oliver is really the Arrow. Quentin then got a call and is informed about the failed attack on Roy at the prison, which he then told Thea about, much to her worry. After Roy is supposedly killed in prison, Quentin went over to Thea's loft to inform her about the situation. Oliver later arrived and comforted Thea as she cried. Later, Thea wistfully looked at pictures of her and Roy on her phone as she drank wine. Suddenly, Ra's al Ghul appeared in the loft. Thea vowed that her brother was going to kill him, but Ra's al Ghul corrected her, claiming that Oliver is going to beg him for mercy. Thea then threw a knife at Ra's al Ghul and tried to run towards the door, but he stopped her. A brief fight occurred as Thea tried to defend herself. Unfortunately, Ra's al Ghul had the upper hand and smashed Thea through a glass table. He then stabbed Thea through the chest with his sword and whispered a prayer before leaving. Thea was left on the floor with her life hanging by a thread as she started to bleed out.

### Resurrection

Oliver arrived at the apartment and immediately took Thea to the hospital, where her condition began deteriorating. Oliver, Malcolm, Diggle, and Felicity decided to bring Thea to Nanda Parbat, where she would be resurrected and healed by the Lazarus Pit in exchange for Oliver accepting Ra's al Ghul offer. Thea's body was prepared by the Priestess and lowered into the pit. Seconds later, Thea jumped out and attempted to attack Oliver in a feral manner, but was subdued. When she woke up, Thea's memories were scattered as she had no recollection of who Oliver was, looked to Malcolm for comfort, and asked about her mother. When Felicity's plan to escape with Oliver fell flat, Oliver helped them by using his control over the other assassins. Oliver bid goodbye to his friends and Thea, asking her to never forget that he loves her. The next day, Thea woke up and regained her memories. As Malcolm recapped what happened, Thea was concerned about her brother.

### Oliver Attacks DC

Thea and Felicity had dinner with Diggle, Lyla, and their daughter, Sarrah. When Diggle wondered how she was doing after her resurrection, Thea assured him she was fine. Thea expressed that she misses Oliver and blames herself for his transformation. Thea later returned to the Arrowcave and talked to Felicity about her desire to help the team out on their mission. She then realized Oliver is back in town and wanted to talk to him, but Felicity dissuaded her. Thea headed back to her loft and contacted Malcolm, who informed her that Oliver is hunting down Nyssa so he could kill her and have no rival as Ra's al Ghul’s successor. He tried to convince Thea to not get involved but she protested and persuaded him to help her instead.

Later, during a battle involving the exchange of Lyla and Nyssa, Thea shot Oliver in the wrist with an arrow as he attempted to kill Diggle. This enraged Oliver, but he spared Diggle's life and left with a captured Nyssa. Thea then returned to the Arrowcave with the rest of the team, who admitted they have probably lost Oliver to Ra's al Ghul and must now reassemble their efforts without him. That night, Felicity came over to Thea's home and talked to her about Oliver, with both women admitting they still love him. Felicity told Thea that they must move on with their lives and revealed to her about Roy being alive, as well as the fact that they staged his death. Felicity gave Thea a paper with his location and whereabouts, stating that she has an opportunity to start a new life with Roy if she wished.

Thea packed and headed to Monument Point to visit Roy. She brought him his Arsenal suit, explaining she had her father steal it out of impound. The two spent the night together at Roy's new home. Later, Thea explained what had happened after Roy left and how Oliver sacrificed his soul for hers. Roy informed Thea that he can't stay in Monument Point forever and will have to move again before someone figures out his identity. The following morning, Thea found herself alone in bed. She went to the auto-shop Roy worked at, only to learn he had quit. One of the mechanics gave Thea a letter and package meant for her. In the letter, Roy urged Thea to live the life which Oliver had sacrificed himself for and not one on the run with him, as he loved her too much for that. Thea then found out Roy had bequeathed her his Arsenal suit, stating that red always looked better on her

.
Thea returned to Washington, DC in time to face the threat of Ra's al Ghul bio-weapon attack, where she donned Roy's suit and arrived in time to save Diggle from a League member. Diggle interrogated the assassin for the Alpha-Omega's location, only to discover he was carrying the toxin in his blood and released it by slitting his own throat. Diggle insisted Thea leave but she assured him that Malcolm had already inoculated her. The two worked together to evacuate as many people as they could to save them from the virus and took down the fourth assassin before he could release it. This bought enough time for Oliver to kill Ra's al Ghul and Ray Palmer to release the vaccine, curing everyone who'd been exposed. Team Arrow returned to Palmer Technologies, where Oliver commended the efforts of everyone present and declared his intention to retire from vigilantism, acknowledging that the city is in capable hands.

At her loft, Malcolm informed Thea that he intended to leave Washington, DC as well and tried to justify that regardless of everything he did, he will always love her and be there if she needs him. Though Thea was uninterested in his offer, she acknowledged the promise Malcolm made to make her stronger and thanked him for it. Thea later tried to convince Oliver not to leave the city, with no luck. Before he left, Thea asked if Oliver has a codename for her, suggesting "Red Arrow", but Oliver had already told everyone to call her "Speedy". Annoyed but humored, Thea bid farewell to Oliver as he left with Felicity.

### Working with Team Arrow

After Oliver and Felicity left, Thea moved in with Laurel at the latter's apartment since she was haunted by almost being killed by Ra's al Ghul in her home, but still kept the loft in her name. Eventually, a new terrorist group coined "The Ghosts" began a series of attacks across the city, beginning with robbing banks and jewelry stores and escalating into stealing munitions and technology. The Ghosts proved to be a match for Team Arrow and would commit suicide using cyanide pills if captured.

In October 1403 during a siege of a Kord Industries weapons truck, Speedy and Black Canary moved in to intercept, where Speedy fought against a few men. One of the Ghosts pinned her down, but Diggle saved her before Black Canary blew up the truck wheels. However, the Ghosts had brought backup and escaped with their cargo. At the Arrowcave, the team discussed the hijacking, with Laurel and Thea agreeing that they were outmatched and needed Oliver's help, against Diggle's wishes. The next day, the city's leadership committee was targeted by the Ghosts' organization through various means of assassination.

Thea failed in attempting to save one of them. Thea and Laurel then traveled to Ivy Town, where they revealed to Oliver and Felicity of the Ghosts and how they were outmatched. Oliver reluctantly agreed to return to Washington, DC until the new threat was dealt with. Eventually, Team Arrow found the Ghosts and observed as their leader addressed his men and killed one of them for failing to deal with the vigilantes. He then killed some other Ghosts by simply touching him. As Team Arrow attacked, Speedy engaged one of the Ghosts but became unhinged and repeatedly punched him, almost stabbing him with her sword until Oliver stopped her.
As Oliver and Thea searched for the bomb the Ghosts intended to use on the new railway line, Oliver addressed her outburst but she tried to assure him she was fine. At the opening of the railway line, Speedy evacuated the civilians as Team Arrow worked to defuse the bomb. After succeeding, Thea was present as Oliver revealed the Ghosts' leader to be Damien Darhk, Ra's al Ghul's most bitter enemy, but was confused since Damien had already left Washington, DC months ago. Thea later witnessed Oliver broadcast a statement to Washington, DC, declaring his intention to protect it as "Green Arrow".

Thea helped the team try to prevent another Ghost attack. Later, Oliver and Thea had brunch at the loft with their mother's old friend, Jessica Danforth, and her daughter, Madison Danforth. Jessica told them of her plan to run for mayor. At Jessica's mayoral announcement, Oliver and Thea protected her from Lonnie Machin, a man hired by Damien Darhk to kill Jessica. When Thea tried to torture a drug dealer to get information on Machin, Oliver sent her away. Oliver later called Thea out over her recklessness, ordering his sister to not be so aggressive when she's out in the field. Thea suddenly mindlessly attacked him until Laurel and Diggle subdued her. Oliver then revealed that Malcolm had warned him about Thea's resurrection changing her, which he was initially unconcerned about since she appeared to be fine.

### Dealing With Bloodlust

Thea later explained to Laurel that Oliver revived her using the Lazarus Pit in Nanda Parbat when Ra's al Ghul fatally stabbed her. After the team were able to locate Machin and rescue a kidnapped Madison, Thea went too far and set Lonnie on fire in a fit of rage, much to her horror. At Laurel's apartment, Oliver apologized to Thea for not telling her about her bloodlust sooner and assured her that they will deal with this together. Laurel offered to take Thea out of town for a spa weekend to clear her head, which Oliver agreed to.

When Laurel and Thea arrived in Nanda Parbat, Malcolm refused to resurrect Sara as the Pit had never been used to bring a person back from the dead. Thea confided in Malcolm about the bloodlust she experienced recently and asked for his help. Malcolm claimed there was a sage on a nearby mountain who could help her. That night, Thea was awoken by two assassins breaking into her room, whom she killed. Malcolm revealed that the only way for Thea to get rid of the bloodlust was to kill the one who originally hurt her, which was impossible since Ra's al Ghul was dead. Thus, Thea could only periodically satiate the bloodlust by killing.

When Thea and Laurel returned to Washington, DC, Thea agreed not to tell Oliver about their experience in Nanda Parbat. Thea joined the rest of the team when Oliver announced to them that he intended to run for mayor and then went down to the new and improved Arrowcave, which was underneath Oliver's campaign office. When the team needed to draw out a team of cops from the Rogue DC Anti-Vigilante Task Force, Thea got in touch with her old drug dealer to buy $74,000 of cocaine. However, the cops stole the drug shipment and escaped. After the task force kidnapped Quentin, Thea aided the team in preventing the cops from stealing weapons within the DCPD. Afterwards, Thea used her connections to hire a team of interns for Oliver's mayoral campaign. She wrote a speech for her brother's mayoral announcement and witnessed him give it.

Thea confessed Malcolm had her kill two League members to quench her bloodlust.

Alex went over their campaign itinerary with Thea and Oliver. When Oliver left, Alex asked Thea out on a date which she rejected, citing her already complicated life. Thea later helped Team Arrow in stealing a quantum manifold from Kord Industries and regrouped with them when they discovered Ray Palmer being held captive in the Latin Building by Damien. While the rest of the team recovered Ray, Thea and Laurel attacked the Ghosts head-on, The next morning, Thea asked out Alex for some drinks later that night.

Thea accompanied the team in fighting off a Ghost attack on a Starling Bank armored truck. During the fight, Thea nearly killed a Ghost with her sword, but managed to stop herself. However, the Ghosts were successful in burning the money. The team later broke into Wolfman Biologics. Malcolm then visited Thea since he knew Thea's bloodlust was returning. He gave her a file on a pedophile who lived three blocks away that he wanted her to kill. Thea angrily refused and left. Thea's relationship with Alex grew as she took the first step towards their date. After participating on a mission to rescue Ray Palmer from HIVE, Thea's blood-lust returned and affected her during dinner with Alex. When she encountered Damien Darhk in the fight to save Clyde Diggle, Damien tried to suck the life-force out of her, but his powers failed against her. Later, Thea asked Malcolm to use that as an advantage.

Thea was present at Oliver's cleanup of Starling Bay, where a drone opened fire on the crowd. Thea later supported Oliver's plan to expose Damien Darhk's identity to the public. Malcolm later paid a visit to Thea, informing her that Damien's powers that mitigated her bloodlust were not related to waters from the Lazarus Pit. Thea was later kidnapped by Damien at Oliver's mayoral holiday party and put into a gas chamber along with Diggle and Felicity. Laurel and Malcolm (dressed as the Green Arrow) arrived and broke them out of the gas chamber. Later that night, Thea happily watched on as her brother proposed to Felicity.

Thea delivered flowers from Oliver to Felicity before her surgery. She later talked to Laurel about her concern regarding Machin's return and her regret for burning his face in a bloodlust-driven rage. They then walked in on Quentin and Donna Smoak and realized the two were dating. Thea took Donna to the cafeteria to give Quentin and Laurel some space to talk. Team Arrow tracked Machin to his foster parents' house, but he rigged a motion sensor gunfire trap. Thea escaped and pursued Machin, holding him at arrow point. However, the rest of the team intervened and took him into custody. Thea later interrupted Oliver's interrogation of Machin in an abandoned warehouse to inform him that Felicity was out of surgery. Thea then started questing Machin, who began taunting her. As Thea started threatening him, Machin tried to goad her into killing him. Thea held an arrow to his throat and started drawing blood but the police arrived, forcing her to flee. Feeling like she was losing control of herself, Thea went to see Alex and break up with him. However, Alex reminded Thea of her resilience in face of multiple tragedies, affirming that she was strong enough to get through her issues. The team later found Machin at Damien's home. Thea and Oliver battled Machin while Laurel and John got Damien's wife and daughter out safely. Thea caught up with Machin in the forest and used a trick arrow to tie him to a tree. However, she hesitated in killing him, allowing Machin to cut himself free with a hidden knife and escape once again. After the mission, Thea invited Alex over for wine and they kissed.

When Diggle and Lyla were ambushed by armed attackers, Team Arrow helped them track down the culprit, Shadowspire, who had kidnapped two ARGUS operatives. The team tracked them to Pacific Freeport, but found the two agents already dead. They later monitored Shadowspire's next target: a shipment of railguns from Kord Industries. However, the rail guns were a ruse and Shadowspire's real target was ARGUS headquarters. Thea, Oliver, and Laurel burst into ARGUS under Felicity's instructions and helped take down Shadowspire before they could access Rubicon.

Despite the potential asset of her immunity to Damien's powers, after Thea's bloodlust reached a point where her body was starting to destroy itself because she wouldn't kill others, Oliver arranged for Nyssa to give Thea the cure after helping her regain control of the League of Assassins. Thea continued with the team after a brief reunion with Roy, but after she fell under Malcolm's influence again and threatened to kill Damien's daughter after being released, Thea decided to leave the team as she didn't like what she was becoming.

### Retired From The Vigilante Life

Although she retired from life as a vigilante, Thea continued to help Oliver in a civilian capacity as his Chief of Staff (Oliver having been appointed Mayor after the death of Ruvé) and has proven herself to be an able politician, often picking up the slack for Oliver, who simultaneously worked as the Green Arrow. In October 1404 when Oliver was kidnapped by Tobias Church, Thea returned as Speedy to help rescue him. However, she grew furious upon seeing that Oliver was willing to kill beyond last resort in the wake of Laurel's death. They had an argument and Thea refused to return to the team. She hired Quentin Lance, who had been fired from the DCPD after revealing that he had previously collaborated with Damien Darhk, as the city's Deputy Mayor.

### In An Alternate Reality

Thea was placed into a computer-simulated reality where her parents, Tomlain, and Laurel were all alive, Oliver was getting married to Laurel, and she was the owner of Verdant. Thea eventually realized this reality was fake when she experienced visions from the real world, including her mother's death, but wanted to stay, despite Oliver and Sara's protests. Thea pointed out that she and Oliver finally had a chance to be happy and didn't want to lose her family again. Though saddened, Oliver accepted this and left. At the last minute though, Thea changed her mind and helped Oliver and her friends battle visions of their enemies, personally defeating a vision of Malcolm. Thea watched on as Oliver and Sara bid goodbye to Laurel before the group left the reality through a portal in Smoak Technologies.

After this ordeal, Oliver arranged for Thea to be dropped off back in Washington, DC.

### Back on Lian Yu

After Oliver's near-impeachment, Thea decided to resign as his Chief of Staff, fearing that she was relying too heavily on dirty politics, including tarnishing a reporter's reputation and considering blackmailing a city council member for his vote.
Thea, along with the rest of Team Arrow, was captured by Adrian Chase and taken to Lian Yu. After stepping on a landmine, Thea was pushed off of it by her father, who had joined forces with Oliver to rescue her; he later detonated the landmine to take out Digger Harkness and some of Chase's henchmen, leaving Thea devastated over the loss of a man whom she hates but comes to terms that while Malcolm was not a good father or person, he proved that he loved Thea.

### In A Coma

During the destruction of the island, Thea was rendered comatose. Five months later, she was on life support at Starling General Hospital. Thea finally awoke from her coma on Thanksgiving, much to Oliver's joy. She had a mini Thanksgiving dinner with Oliver, Felicity, Diggle and William and began to get to know her nephew. Thea attended Oliver and Felicity's wedding celebration in which she remarked about how nobody but Diggle had been invited. Afterwards Quentin Lance took her back to her apartment only to discover Black Siren. Black Siren knocked out Thea and Quentin, kidnapping the latter and leaving a phone on the former. Thea delivered the phone to Oliver and later talked with Oliver about Rene Ramirez's betrayal.

### Leaving DC

After Quentin fired Rene as Oliver's Chief of Staff, he rehired Thea to fill the position.

When Roy is kidnapped by Ricardo Diaz, Thea decides to be vigilant again to save him. Later, they decide to leave Washington, DC to be together.

Thea, Roy and Nyssa leave Washington, DC.
Later, Thea and Roy are intercepted by Nyssa al Ghul when they are leaving Washington, DC, so Nyssa informs Thea of ​​the Thanatos Guild's threat against her, as she is also an Heiress to the Demon. So Nyssa enlists Team Arrow's help to obtain Malcolm's last sift before the Thanatos Guild can retrieve it. With the help of Nyssa and Team Arrow, she uncovers a map revealing the existence of three more Lazarus Pits around the world. Thea decides to leave Washington, DC to travel the world to destroy Ra's al Ghul's remaining Pits alongside Nyssa and Roy.

### League of Heros

Thea proposes forming a "league of heroes" with Thalia al Ghul.
They had discovered and destroyed two Lazarus Pits. So Roy is killed by the Thanatos Guild and then revived by Thea and Nyssa with one of the Pits.
Later, Thea finds Oliver and Thalia al Ghul in Nanda Parbat. They plan to retrieve The Chronicles of Al-Fatih, but are ambushed by Athena and the Thanatos Guild. They manage to escape and eventually find the book. With the Thanatos Guild now dead, Thea, suggests to Thalia that they should rebrand the League to become heroes instead of assassins. Thalia initially refuses Thea's proposal due to her several disagreements but Thalia dismisses those as mistakes, making Thalia accept her offer.
