| Ronnie and Stein turn into Firestorm and help Barry destroy the singularity, but at the cost of Ronnie's life. Six months later, Barry operates alone, using his speed to repair Central City while being embraced by the public as a hero; Cisco works in the police department alongside Joe, and Caitlin works at Mercury Labs. Barry evaluates a crime scene with a victim named Al Rothstein. At a ceremony, the Flash is attacked by Atom-Smasher, whose strength and size manipulation prove too much for Barry, who forces his mask off. Underneath the mask, Atom-Smasher is revealed to look exactly like Rothstein. Barry is convinced by Joe and the others that he needs help in taking down certain metahumans and Rothstein is defeated by over absorbing radiation. While dying, Rothstein tells Barry that he was sent to kill him by someone called "Zoom". Barry receives a flash memory from Harrison Wells' (Eobard Thawne) lawyer containing his confession to killing Nora. Henry is exonerated and released from prison, and leaves Central City so that Barry can focus on being the Flash. A man arrives at S.T.A.R. Labs, introduces himself as Jay Garrick and tells the team that their world is in danger. ||||||||

Stein confirms the claim, describing their world as "Earth-1" and Jay's as "Earth-2". Zoom brings another metahuman from Earth-2 called Sand Demon, later identified as Eddie Slick, to kill the Flash. Cisco analyzes the "sand" left behind and has a vision of the previous fight, frightening him. After Slick kidnaps Officer Patty Spivot, Jay teaches Barry how to hurl lightning. Cisco uses his power to find Patty's location. Barry uses the lightning blast to turn Sand Demon's particles to glass, killing him. Patty reveals to Joe that Mark Mardon killed her father.

Meanwhile, Lisa Snart shows up asking for Flash's help in rescuing Snart, whom she believes was kidnapped. Barry tracks down Snart, who is revealed not to be kidnapped but is working with his father, Lewis. Lisa states that Snart would never work with Lewis willingly, because the latter was abusive toward her when she was a child. Eventually, the team determines that Lewis placed a bomb inside of Lisa and threatened to kill her if Snart did not help him with his theft. Barry infiltrates Lewis' crew with assistance from Snart. Cisco successfully removes the bomb from Lisa, so Snart uses his cold gun to kill his father in retaliation. Snart is incarcerated in Iron Heights and Lisa leaves.

Jefferson initially refuses, but agrees when Hewitt goes on rampage. After the successful merger, the new Firestorm joins Barry in helping to take down Hewitt, who is incarcerated. Before departing with Jefferson, Stein encourages Cisco to tell the others about his powers. Meanwhile, Francine reveals that she is suffering from a terminal illness and only has months to live.

Barry recognizes her as the Earth-2 version of Linda. Later, Light attempts to kill Linda and take over her identity, but accidentally kills Linda's boss and is stopped by Barry's team in the process. Harry reveals Cisco's powers to the team, which Cisco uses to locate Light. Barry defeats her with the help of Harry.

Barry reveals his alter ego to Linda. Harry creates a speed dampening serum and the team stages a fight at one of the breaches in order to trick Zoom through. The attempt fails, as Zoom knew the plan. Instead, he goes after Linda, before fighting Barry. Zoom is much faster and easily overpowers Barry, showing him defeated with his unconscious body to the local news and the police station before ultimately returning to S.T.A.R. Labs. Zoom stabs Barry with his hand, but Cisco shoots him with the serum, which hurts Zoom, but still leaves him with enough speed to escape.

Iris reaches out to Henry, who returns to help Barry overcome his fears. Wells formulates a plan to close all of the breaches, except one, through which Zoom can enter into the trap set for him. Cisco touches Kendra, but leaves after seeing a winged person in a vibe. Grodd returns, using scientists to steal various chemicals in the hopes of creating more gorillas with his level of intelligence. He later kidnaps Caitlin to help him with his plan. Harry dresses up as the Reverse-Flash in order to trick Grodd into thinking that his "father" is still alive. The plan works long enough for Harry to rescue Caitlin before they both escape. After Barry is fully recovered, they lure Grodd to one of the dimensional breaches and send him to a jungle sanctuary for gorillas that have been experimented on in Earth-2. Later, Cisco meets Kendra again, this time vibing and seeing her as the winged figure. ||||||||

The speedster turns out to be Eliza Harmon, a Mercury Labs employee who developed Velocity-9 from samples Caitlin gave her to help with Jay's illness. Operating under the alias "Trajectory", Harmon invades S.T.A.R. Labs, imprisons Barry, and demands more V-9. After she threatens Jesse's life, Wells and Caitlin make more of the drug for Harmon, who then speeds off to wreak havoc on the city. Barry manages to stop her before she injects more V-9 into her system. Barry watches as Harmon's speed becomes so intense that her lightning turns blue and she disintegrates. Jesse decides to leave the city to experience the world on her own and stop Wells from doing harmful things just to protect her.

In the present day, Barry tests the tachyon accelerator, and is able to enhance his speed four times greater than normal. Barry decides to re-open a breach back to Earth-2, and he believes that Cisco's powers are the key to opening the portals. Meanwhile, Caitlin reveals that Jay's Earth-1 doppelgänger is Zolomon and Wells, shocked to hear this, reveals that Earth-2 Zolomon was a convicted serial killer. Zolomon was receiving electroconvulsive therapy during the explosion, and was one of the many affected. With this revelation, the team confirms that "Jay" is Hunter. Cisco opens a breach, and Zoom immediately appears, chasing Barry back to S.T.A.R. Labs. There, Barry uses images of Zolomon's parents as a distraction to trap him, but Hunter escapes, claiming to be "the darkness".

## Production
### Development

On January 11, 2015, The Flash was renewed for a second season. With the commencement of production on the season, former Arrow and Ugly Betty writer Gabrielle Stanton was promoted to executive producer and showrunner; after having served as consulting producer and writer on the first season's finale "Fast Enough". However, it was later reported that series co-creator Andrew Kreisberg would be returning to sole showrunner duties at an unspecified time. That time was later proved to be at the start of 2016, "Potential Energy", when Stanton was no longer credited as being involved with the show. Aaron and Todd Helbing also served as the season's showrunners.

### Casting

Main cast members Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes and Jesse L. Martin return from the first season as Barry Allen / The Flash, Iris West, Caitlin Snow, Cisco Ramon / Vibe and Joe West, respectively. Tom Cavanagh, who portrayed Eobard Thawne impersonating Harrison Wells in season one, also returned as a regular, playing Wells' Earth-2 doppelgänger. Rick Cosnett, a main cast member from season one, did not return as a regular because his character, Eddie Thawne, died in the season one finale. He instead returned as a guest star in the season premiere "The Man Who Saved Central City" in a dream sequence, and later in the episode "Flash Back", where Barry travels back to a time when Eddie was still alive. In August 2015, Keiynan Lonsdale was cast as Wally West, the unknown son of Joe, and Iris' brother. Gustin, Patton, Panabaker, Valdes and Martin also portray the Earth-2 versions of their characters in the episode "Welcome to Earth-2", while Cavanagh portrays Thawne impersonating the Earth-1 Wells in "The Man Who Saved Central City" and "Flash Back".
Discussing the casting of Lonsdale, Kreisberg stated, "Just like when we met Grant [Gustin] for the first time, we instantly knew Keiynan embodied all the heart and courage of a hero. We are so excited to be bringing this much-beloved character onto the show." It was always intended for Wally to be the son of Joe and brother of Iris, which differs from the character's comic history, as the producers disliked second seasons of television series that would introduce cousins of characters that were never previously mentioned, feeling it was "weird". Lonsdale originally auditioned for Legends of Tomorrow to portray Jefferson "Jax" Jackson.
Shantel VanSanten appeared in a recurring role as Barry's love interest Patty Spivot. VanSanten's character departed after the mid season premiere. The reason was initially reported as being due to scheduling conflicts with Shooter; VanSanten later revealed in an interview that she was set to return but "one of the showrunners at the time took a personal disliking to her".
In July 2015, it was announced that Teddy Sears would recur in the role of Jay Garrick, the Flash of Earth-2. However, later in the season it was revealed that his character was actually Hunter Zolomon / Zoom posing as Jay. Ryan Handley portrayed Zoom in costume prior to this revelation, while Tony Todd voiced Zoom.

### Design

Maya Mani replaced Colleen Atwood as the costume designer for the second season and made slight changes to the Flash costume, such as changing the color of his chest emblem from red to white, being faithful to the Flash costume from the comics. Gustin stated that, around the time of filming the season's ninth episode, "we stopped gluing the mask to my face and switched to a mask that just slipped on and off with a zipper". While Zoom's costume in the comics is a verbatim replica of Eobard Thawne's yellow-and-red Reverse-Flash costume, the costume seen in the TV series is entirely in black. Kreisberg compared Zoom's appearance to that of the Marvel Comics character Venom, saying, "The Zoom outfit is much more organic than the Reverse-Flash suit. In a way, it's hard to tell if it is a suit or alive... There's no skin showing, for all you know there's a robot underneath, or dark energy."

### Filming

Production on the season began on July 7, 2015, in Vancouver, British Columbia, and concluded on April 18, 2016.

### Music

Composer Blake Neely returned as the primary composer for the second season. The soundtrack for the second season was released digitally on July 22, 2016 and in CD format on July 26, 2016. Neely also composed a theme when Gustin as Barry appeared on the eighteenth episode of Supergirl, "Worlds Finest". The theme was titled "World's Finest" when it was released on the Supergirl: Season 1 soundtrack.
All music composed by Blake Neely.

### Arrowverse tie-ins

In October 2015, Arrow showrunner Wendy Mericle revealed that the producers of the Arrowverse had begun having someone track all the characters and plots used by each series, in order to make sure everything lines up, though Aaron Helbing noted in April 2016 that "sometimes the schedules don't line up exactly...and that stuff is out of our control", such as when Barry is shown using his abilities on Arrow that month, while not having them the same week on The Flash.
The second season of The Flash began to explore the concept of the multiverse, by introducing Earth-2, which features doppelgängers of the inhabitants in the Arrowverse (or Earth-1). In "Welcome to Earth-2" of The Flash, glimpses of the multiverse are seen, including an image of Supergirl star Melissa Benoist as Supergirl and an image of John Wesley Shipp as the Flash from the 1990 television series, implying that those two television series exist on alternate Earths to the Arrowverse.
The second annual two-way crossover with Arrow aired on December 1 and 2, 2015, where the Flash and the Green Arrow team up to take on Vandal Savage, who is looking for Kendra Saunders and Carter Hall, the reincarnations of Hawkgirl and Hawkman. Though Legends of Tomorrow did not have an episode as part of the 2015–16 crossover, the Arrow and The Flash episodes from this event did set up a number of characters who star and recur in that series. Casper Crump, Falk Hentschel and Peter Francis James debut in the crossover, as Vandal Savage, Carter Hall / Hawkman, and Dr. Aldus Boardman, respectively. Screen Rant's Alice Walker discussed how the annual Arrow/The Flash crossover suffered from also trying to set up Legends, which was "too much to ask from the already crowded storylines and ended up feeling like an exercise in synchronicity, with producers planting more seeds than they could reap. The crossover event was no longer a fun way to contrast the two shows; it now had to serve the much larger purpose of setting up an entirely new world."

#### Crossover with Supergirl

In February 2016, it was announced that Gustin would appear on the eighteenth episode of Supergirl, with Berlanti and Kreisberg, also Supergirl executive producers, thanking "the fans and journalists who have kept asking for this to happen. It is our pleasure and hope to create an episode worthy of everyone's enthusiasm and support." While no plot details on the episodes were released at the time, Ross A. Lincoln of Deadline Hollywood noted that "the in-universe reason" for the crossover was due to Barry's ability to travel to various dimensions, thus implying that Supergirl exists on an alternate Earth to the Arrowverse in a multiverse. "Welcome to Earth-2" confirmed this, showing an image of Benoist as Supergirl during a sequence where characters travel through that multiverse. The Earth that the series inhabits has been informally referred to as "Earth-CBS" by Marc Guggenheim, one of the creators of Arrow.
In "Worlds Finest", which aired on CBS on March 28, 2016, Supergirl is established as being in an alternate universe where the Flash helps Kara fight the Silver Banshee and Livewire in exchange for her help in returning home. The episode title was inspired by the World's Finest Comics series, in which Superman would team up with various other DC superheroes, including the Flash. The events of this episode take place between two moments in the eighteenth episode of The Flash season two, "Versus Zoom", which aired on April 19, 2016, in which Barry enters and exits a breach while wearing the tachyon device seen in this episode. The crossover required "a lot more logistical trickery" than the usual Arrowverse crossovers due to Gustin filming The Flash in Vancouver alongside Arrow and Legends of Tomorrow, while Supergirl is produced in Los Angeles. The producers chose to use the Flash as the character to crossover, due to his ability to travel between various Earths, and because it was "a little more fun at first to bring the veteran from that show to the chemistry of a new show." Berlanti stated that "in a perfect world", the crossover would have featured both Gustin and Amell's Green Arrow, "but logistically that would have been a nightmare to try and do both shows. We had to facilitate one." Gustin was optimistic that the crossover in 2016 would allow another crossover the following year with the rest of the Arrowverse shows.
The crossover episode received excellent reviews. Cliff Wheatley of IGN gave the episode an 8.6/10, stating "After the grim 'n' gritty Batman v Superman, Supergirl's "Worlds Finest" offered a fun, upbeat palette cleanser and one of the series' strongest episodes to date. Instead of the usual "beatdown" introduction, Supergirl and the Flash went straight to being superfriends, which was refreshing. Not only did Barry Allen fit perfectly in Kara's world, but actors Grant Gustin and Melissa Benoist had fantastic chemistry together onscreen. While the city's turnaround on Supergirl's Red K incident was a little sudden, overall, "Worlds Finest" was delightful." Stacy Glanzman of TV Fanatic gave the episode a 5.0 out of 5 stars.

### Critical response

The review aggregator website Rotten Tomatoes reported a 94% approval rating for the second season with an average rating of 7.84/10, based on 24 reviews. The website's consensus reads, "With distinctive visuals and a terrific cast, The Flash remains one of the strongest comic book shows on television." Metacritic, which uses a weighted average, assigned the season a score of 81 out of 100, based on 4 reviews, indicating "universal acclaim".
Reviewing for Collider, Dave Trumbore gave the season premiere a rating of 4 stars out of 5, saying, "All in all, a very good way to start season two after the strong run of season one." Mike Cecchini of Den of Geek! meanwhile rated the episode 3.5 stars out of 5, criticizing the episode's "unsettled" and "rushed" nature. He felt that the episode "seems so focused on getting this season off to a running start that it [...] doesn't give events time to breathe." Erik Kain of Forbes noted a "very big piece" missing in the absence of Harrison Wells, but felt that the episode was "an excellent start to the sophomore season of the CW's best super hero show." Although Henry Allen's abrupt exit was a common point of criticism amongst reviewers, Trumbore nevertheless felt that it was "a small price to pay for an otherwise cohesive, entertaining, and emotionally satisfying episode."
The episode "Welcome to Earth-2" received a number of positive reviews. Erik Kain said that it was "The Flash at its best. An engaging, funny, scary episode that hits all the right notes from start to finish." IGN's Jesse Schedeen rated it 9.7 out of 10, praising the concept of Earth-2, Barry's dramatic moments, the depiction of Deathstorm, Killer Frost, and Reverb, but criticized the need to kill off Reverb so soon. He concluded, "The Flash delivered one of its best episodes yet as Barry and friends took a hilarious but emotional trip to Earth-2." Angelica Jade Bastién of Vulture said the episode "marries incredible action sequences, amazing direction by Millicent Shelton, some of the cast's best acting (particularly from Candice Patton and Grant Gustin), lots of heart, and just the right number of nods to the comics. It is undoubtedly the best episode of the season, and just may be the best episode of The Flash yet." Dave Trumbore rated the episode 4 stars out of 5, saying, "This was an absolutely insane episode of The Flash, and that's saying something since this show is normally fast-paced and full of Easter eggs even on a relatively slow week." Entertainment Weekly's Jonathon Dornbush praised the scene where Barry talks to his Earth-2 doppelgänger's mother over phone, saying Gustin "has proved mightily adept at tackling Barry's grief, hope, and the many other emotions swirling around in regard to his mother and her death." Scott Von Doviak of The A.V. Club said, "Since its return from hiatus, The Flash has been sluggish and morose, and the Zoom arc has fizzled. 'Welcome to Earth-2' jump-starts both the storyline and the season as a whole [...and] is just about as good as The Flash gets."
Reviewing the season finale, Allison Keene of Collider directed specific praise to Gustin's performance, saying "Sometimes a great TV performer can come out of an already fantastic episode, but occasionally an actor can rise above the material, proving that even though the writers have let them down, the actor is going to make the most of what they've been given. That's exactly where we find ourselves with The Flash's head-scratching finale, which capped off a largely enjoyable but ultimately uneven second season. What has never been in doubt, though, is star Grant Gustin's ability to convince viewers that this all makes sense in an emotional, earnest, and often light-hearted way." In his review for Nerdist, Joseph McCabe concluded, "For all this season's faults, most of which came from repeating the major villain arc of season one, [...] there were moments in the last handful of episodes where Barry demonstrated more independent thought than the show often allows him. Coming up with his own ideas, for example, to defeat the villain of the week rather than relying on his friends at S.T.A.R. Labs. That's the Barry I want to see more of in season three.
A number of critics felt that the season as a whole suffered from the standards set by its predecessor, calling it "uneven" and criticizing the handling of the season's main villain. Collider's Kayti Burt gave the season 3 stars out of 5, saying, "The Flash finished off an uneven season with an uneven finale that couldn't overcome the burden of an underdeveloped, illogical villain. With Zoom, The Flash fell victim to a common drama mistake of a contemporary TV era: it prioritized the plot twist over the well-developed character arc." Jeff Jensen of Entertainment Weekly gave the season a "B−" grade, calling it "certifiably slumptacular" and said that the "bold" introduction of the multiverse did not meet his expectations. Jensen praised Barry's onscreen rapport with Joe but felt it was underutilized due to the introduction of Joe's biological son Wally, and criticized Barry's romantic fixation for Iris. He also criticized Zoom, saying, "He began as an alluring mystery but lost zip over time" and once his identity was revealed, "became a weak embodiment of generic villainy". Jesse Schedeen gave the entire season a rating of 8.6 out of 10, explaining, "This season met and occasionally even exceeded the heights of its predecessor. But it was also a more uneven and ultimately more flawed experience in the end."

### Accolades

The Flash was included on multiple Best/Top TV Shows of 2015 lists, ranking on The Salt Lake Tribune's (4th), Omaha World-Herald's (7th), and IndieWire's (10th), as well as on un-ranked lists of Criticwire and Variety. In its second season, The Flash was nominated for 20 awards, winning five. The series was nominated for three Saturn Awards, winning Best Superhero Adaption Television Series for the second year in a row. The show was also nominated for three Leo Awards, winning again for Best Visual Effects in a Dramatic Series for the episode "Gorilla Warfare". At the 2016 Teen Choice Awards, the show gained six nominations with Gustin winning for Choice TV Actor: Fantasy/Sci-Fi.
