==History==
===Early Life===
Addison was born in Connecticut in 1967 into a wealthy background with her brother Archer, father "The Captain" and mother Bizzy.
When she was seven, she fell off her bike in the vineyard while going downhill because her tire came off. She flipped over the handlebars and scraped her face on the ground, but Archer picked her up, told her it was going to be okay, and carried her the half a mile back home. This is how Addison has always seen her older brother, as the big brother who carried her home. 
From the age of eight, Addison was mixing her father, The Captain's drinks.
When she was 10, Addison also had to deny her father's affair with his secretary, waiting for "daddy" while he was having sex in his office and then pretending she had fun getting ice-cream with her father. Her father also had affairs with (among others) 3 maids, 4 of Addison's nannies, Jolene her French tutor, and the chef. She only discovered in adulthood that it was her mother who had cheated first, with a woman but chose to stay married because she already had a family. The Captain knew but also stayed with her, but had affairs with other women.
When she went to prom in high school, it was with Skippy Gold. Addison was a band geek with braces and a lisp, and she was forced to talk about Star Wars the whole night.
Addison attended college at Yale University and medical school at Columbia University College of Physicians and Surgeons where she met her future husband, Derek Shepherd; Sam Bennett, a future boyfriend; Mark Sloan, her future lover; and Naomi Bennett, her best friend.
Addison is entitled to a twenty-five million dollar trust fund and owns three properties: a New York brownstone, a house in The Hamptons, and a house at Santa Monica. She now lives beside a beach in Malibu next door to an old friend, Sam Bennett.
===Marriage Problems with Derek Shepherd===
Addison cheated on her husband of over 10 years, Derek with his best friend Mark Sloan. Before this, Addison and Derek's marriage had been an unhappy one, as Derek had been putting in little effort. Derek even mentioned that the demise of their marriage was not her fault alone. They each owned their respective practices, putting a strain on their marriage. When he found Mark and Addison in bed together, he simply walked away.
Derek then picked up his life in New York, sold his private practice, and relocated to Seattle. This is where he began his relationship with Meredith Grey, who later became his wife.
Upon Richard's request to help out with a patient, Addison visited Seattle. When she arrived at the hospital, she saw Derek fixing Meredith's coat in the lobby. Derek turned around and was shocked to see her, his expression enough for Addison to put the pieces together. She walked over and he asked her what she was doing here. She said he'd know if he had bothered to return any of her calls. She then introduced herself to Meredith as Derek's wife, much to Meredith's surprise. She guessed that Meredith was the woman who had been screwing her husband.Who's Zoomin' Who?, 1x09
Meredith ran off, leaving the married couple to talk. She mentioned that his hair looked different, comparing it to Russell Crowe's. He asked her again what she was doing there. She returned the question, pointing out he had abandoned his entire life in New York City. She also brought up his new Seattle girlfriend, who was young, sweet, and in awe of his being a neurosurgeon, whom she summarized as the 'anti-Addison.' He told her to forget about winning him back. She made it clear that was not her intention and stated she was there for a TTTS case on Richard's request. She assumed Richard would have told him. She leaned in and told Derek that she'd always had a thing for Russell Crowe before walking off with a satisfied expression. She went to see Richard, with whom she had a joyful reunion, until Derek interrupted to vent his frustration. Addison left him to it.
The next morning, Addison specifically requested Meredith for the TTTS case. Together, they went to see the patient. In the room, Addison bombarded Meredith with questions. Once outside, Meredith said she could have answered the question had Addison given her the time to do so. Addison commented she was tough on everyone, not just the women sleeping with her husband. She gave Meredith further instructions. Later, Meredith interrupted Addison and Derek talking about her surgical skills to brief Addison about abnormalities found on the ultrasound. Due to signs of heart failure in the babies, they had to operate sooner than planned. Meredith watched closely as Addison worked her magic in the OR. As they checked on Julie after the surgery, Julie requested Meredith be thrown off her case since she had overheard Addison's comment about Meredith sleeping with her husband. Addison then clarified that she had cheated on Derek so the wronged woman here was Meredith, whom she said deserved an apology from Julie.Raindrops Keep Falling On My Head, 2x01
Addison went to visit Richard in his room and found him in the company of Derek and Adele. Adele was delighted to see her and commented that she knew Addison and Derek would get back together, but Derek firmly said that adultery was enough to end their marriage. Later, Addison asked to talk to Meredith and inquired if Derek had told her why he had left her. Meredith said she had nothing to do with that situation. Addison was surprised and impressed to find out that Meredith had not taken Derek back. She added that there are two sides to every story and implied that her cheating on Derek with his best friend had been a desperate attempt to get his attention. At the end of the day, Addison ended up on an elevator with Derek. They shared what they had each told Meredith about their situation. Derek scoffed at the idea of Addison sleeping with Mark to get his attention. Addison replied that she was just scratching an itch by that point and Mark was just there, but it was preceded by years of them getting busy with their careers and lazy in their marriage. Derek made it clear he was not interested in Addison's explanation.Enough is Enough, 2x02
Later, Addison moved into Derek's trailer, and the two attempted to reconcile. Addison asked Derek if they were even after she got poison oak from walking Meredith's dog in the woods. The two laughed over the incident. They divorced after Addison found a pair of women's underwear in Derek's pocket.
After the divorce, Addison had to put Derek in a tiny box and make him petty and insignificant to get up in the morning.
===Relocating to Los Angeles===
Addison had very little in Seattle after she and Derek divorced. Her marriage with Derek was over, her relationship with Mark had completely vanished, and her attempt at a relationship with Alex Karev failed. She visited Los Angeles to see her friends Naomi and Sam Bennett, also because Naomi was a fertility specialist. Naomi offered her a position at Oceanside Wellness Group. Addison returned to Los Angeles not long after that, taking Oceanside Wellness up on their job offer at their practice. One day, Addison searched through Naomi's files at the practice to read her file and found that her chances of becoming pregnant were worse than she'd previously imagined. She learned that her egg count was a mere two, and was heartbroken.
===First Return to Seattle===
 Later, Addison returned to Seattle Grace Hospital to treat a pregnant woman suffering from ectopia cordis, in which the fetus's heart was growing outside of the body. Although she seemed somewhat happy to be back in Seattle, she made it clear that the visit wasn't permanent and she had every intention of returning to Oceanside Wellness Group. Addison also showed that the history between her, Meredith, and Derek was in the past as she was able to hug Meredith and be genuinely happy for them, unaware that they had broken up.
During her stay, in which the surgeries on both mother and child were successful due to Addison, Mark, and Erica's expertise, Addison was forced to realize that a lot had changed in her absence (particularly the breakdown of Callie and George's marriage, Meredith and Derek's break up, and his relationship with Rose, as well as Bailey and Tucker's marital issues.)
When the chief approached her and attempted to persuade her to stay at Seattle Grace, Addison told him that she now knew it was the right thing to leave and told him to fill her position. Before returning to Los Angeles, however, Addison went to Joe's bar and warned Meredith that, even though she was now zen, she wanted to "kick her ass" for not fighting for Derek and allowing his new girlfriend to have the happily ever after that she deserved.Piece of My Heart, 4x13
===Relationship Woes and Trouble at the Practice===
 Addison's status in the dating world remained uncertain as she had been stood up by Kevin after she went to find him at the station, and remained unaware that Pete had gone to her house the same night. Sometime later, Addison and Naomi found themselves at odds regarding Naomi allowing a couple to conceive a child through Naomi's fertility treatment who would act as an organ donor for their ill child. When the parents demanded Addison birth their child three months premature, an ethical debate raged between Addison and Naomi. Addison eventually learned Naomi agreed to help the couple due to the practice's financial trouble that she was concealing from the group. Despite Naomi's pleas, Addison told Sam that the practice was in trouble. At the same time, Kevin returned for Addison to tell her that he stood her up to train for the SWAT team and the two flirted, leaving their future ambiguous.A Family Thing, 2x01 (PP)
Armed with the knowledge of the practice's struggles, Sam and Addison formed a hostile takeover of the leadership of the practice and each doctor worked to save the practice from extinction. Addison and Naomi's friendship, however, couldn't stand what Naomi saw to be a betrayal and Naomi cut her best friend out of her personal life, leaving only professional ties.Equal and Opposite, 2x02 (PP)
With her 'family' at the practice in disarray, Addison took Charlotte's offer to do some surgeries for St. Ambrose, for her to relieve her frustrations which she claimed 'fall away' when she holds a scalpel. However, rushed off her feet and desperate to do nothing but cut Addison spent no time conversing with her patients and getting to know them. When a stressed and worried husband of a pregnant patient asked her what his wife's name was, and she was unable to answer, she realized that she had become the one who wasn't talking and decided to return to family at the practice for good, refuting Charlotte's offer to work at St. Ambrose full-time. This persuaded her to move forward with Kevin as well as attempting to repair her friendship with Naomi.Nothing to Talk About, 2x03
===Archer's Hospitalization===
 Having landed in Seattle, a worried Addison was greeted by Richard and Derek as Archer was prepared for a diagnosis. Derek discovered eight cysts caused by the parasites and, having consulted specialists, revealed that they were inoperable as surgery would cause more harm than good. A reluctant Addison refused to give up on Archer and told Derek that she needed him to be a God. As she attempted to pray in the hospital chapel, Addison confessed to Callie that she didn't believe God knew who she was, and so praying for a miracle was worthless. Her old friend then reminded her that she saves babies, and God knows who she is because of it. Having received the push from Sam, Derek decided to do the surgery. Addison watched on tenterhooks as Derek attempted to remove the parasitic cysts. When removing the eighth and final one, it ruptured, allowing the parasite to dig further into his brain. Addison, however, faced much relief when the parasite was caught, extracted and Archer stabilized. To celebrate Derek's success the old friends visited the Emerald City Bar, where they reminisced about Derek's love song to Addison. Addison however, recognized that Derek was in her past, and, despite her gratitude, she had to once again make him petty and insignificant to move on with her life.Before and After, 5x15
===Relationship with Pete===
After Violet was attacked and gave her baby to Pete, Addison became one of the principal caregivers to Lucas. She filled the void left by his birth mother and was overjoyed at the prospect of having a baby of her own. However, after Violet recuperated, Addison told Pete to go back to her, and subsequently lost touch with Lucas. She was, once again, left without a child of her own.
===Sloan Riley's Surgery===
As Mark wanted the best care possible for his daughter Sloan and was unsure of Elizabeth Chen's abilities, he had Addison fly in for the surgery. When Addison was operating, she realized it would be riskier than she thought. She was confident she could continue successfully, but Mark insisted that she stop. However, he later traveled with Sloan to Los Angeles so Addison could perform it. She did so successfully.
===Callie's Car Accident===
Since Callie and Addison were close friends, Addison flew back to Seattle, at Richard's request after hearing that Callie had been in a car accident. She later performed an emergency C-section on Callie and delivered her daughter, Sofia Robbin Sloan Torres, prematurely.Song Beneath the Song, 7x18
===Meeting Jake and Renewed Pursuit of Motherhood===
After Naomi left, Addison went to therapy.
The night Pete had a heart attack, Addison sat with Lucas and kept him comfortable until Violet was contacted and returned from the airport. She assured him everything was going to be okay, as Sam and Amelia were the best people to take care of him. Despite Sam still not having changes his mind about having a baby, Addison decided to go ahead anyway and made an appointment with the best fertility specialist she could find in the city. That man turned out to be Jake Reilly, her anonymous date she met flirting over pineapples. She then wanted to quit, but Jake had no problem leaving their flirtation in the past. He promised her he'd give her a baby.God Laughs, 5x01 (PP)
Not long after, Jake turned out to be applying for Naomi's job at the practice. Addison, being in charge, was hesitant to hire him. Meanwhile, she informed Sam she was going off birth control, so she had him buy condoms. After Jake assured her he had no ulterior motive and promised not to flirt, Addison had to face that he was the best candidate and officially hired him. Addison told her therapist that she didn't need to tell Sam about her Fiji history with Jake, as they were broken up at the time, and admitted that she finally happy again.Breaking the Rules, 5x02 (PP)
Addison started looking for IVF specialists to start the process. Needing someone to talk to, she grew closer to Violet, who also needed someone to talk to about her marriage problems. Sam later realized he needed to be there for his girlfriend and offered to listen to her talk about IVF specialists, but she told him she was fine. In therapy, she said she became a better and more generous person because of Sam.Deal With It, 5x03 (PP)
However, Addison soon realized she must be crazy to compartmentalize Sam and the baby, starting to fear Sam was going to leave her. She took her concerns to Jake after he told her some more about himself and his youth to make her trust him, but all Jake could tell her was to listen to her instincts. At night, she told Sam what she was worried about. He knew she was, but kissed her to tell her he wouldn't leave. However, in therapy, Addison still said she came to realize that maybe love means wanting the other person to be happy, even if they can't be with you.Remember Me, 5x04 (PP)
Addison started the IVF process with fertility drugs and asked Jake to inject them as she wanted to stay sexy for Sam, so he couldn't do it for her. Addison tried to keep it secret in order not to become the office gossip, but that became difficult when she soon started suffering from mood swings and extreme emotional reactions to what was happening at the practice. Addison started thinking Sam was just dating her because she couldn't have children, but Jake assured her that was just the hormones. He did tell her she needed people on her side, as she couldn't go through it alone. She then told Sam that she started the IVF process with Jake's help. He once again stated he didn't want a new child because the experience of having a child is as awful at times as it is wonderful, so he was glad to have gotten through it with Maya. He assured Addison that didn't mean he stopped loving her, though. In therapy, Addison said she had to teach herself to have hope again.Step One, 5x05 (PP)
Soon after, Addison started looking for sperm donors, throwing out lots of candidates based on medical history alone. When she felt like she was drowning in files, Sam assured her she could make it happen. Addison asked her colleagues for help, but they all give her different advice. Addison received good news from Jake: they were able to retrieve 4 eggs, which needed to be picked that day. He'd contact a friend at the sperm bank to speed up the process, meaning they could fertilize the eggs that day. Sam came to support Addison when Jake would pick the eggs, but she was already under. She woke up with Sam by her side and started crying because she put herself in this position where a stranger was needed to get pregnant, all because she cheated. Sam convinced her the bad things didn't outweigh her good qualities, so she shouldn't punish herself. He advised her to pick the musician's sperm. She did pick him, and later that day, Jake fertilized the eggs with Addison watching.If I Hadn't Forgotten..., 5x06 (PP)
Over the three days the embryo had to grow in the lab, Addison kept checking on it. She wasn't allowed to have sex before the implantation, but Sam suggested they do "other things". She happily agreed to that. Meanwhile, Addison also met Ryan Kerrigan and expressed her worries over Amelia, who assured Addison she was fine. The day after, Jake implanted the eggs. In therapy, Addison said she was thrilled and terrified that if all things went right, there could be an entire person with a full life ahead could be growing inside her. She was looking forward to sharing experiences with her child.Don't Stop 'Till You Get Enough, 5x07 (PP)
Amelia went missing for 12 days, and when she showed up at the practice to announce her engagement to Ryan, Addison was both angry and relieved at the same time. Since Charlotte was convinced Amelia was using, they staged an intervention at the practice. Amelia started attacking them one by one and hit Addison's weak spot when she attacked her about her infertility and past abortion. Addison threatened to report Amelia to the medical board, throw her out of her house and change the locks, and call in her family, but the only thing that actually got Amelia to stay and listen was the oxy she demanded. The doctors gave her the oxy, which Amelia snorted off the reception desk. Right when Amelia seemed to cave to her friends' talks and agreed to go to rehab, Ryan arrived. The doctors suggested they also help Ryan, but a quarrel ensued when Addison noticed Ryan was wearing Amelia's father's watch. Amelia aggressively forbade her from telling that story and soon left with Ryan, leaving Addison to feel like the intervention was a bad idea. However, the next morning, Addison received a call about Amelia, who was ready to go rehab.Who We Are, 5x08 (PP)
Addison helped her pack and drove her to the treatment center. Amelia, who has a great mother, had Addison think that even the best mothers' kids can go down the wrong path. Later that day, Addison received the news that she was not pregnant, but Jake assured her that didn't mean it was over. Sam seemed relieved about the news, so Violet agreed to hold her hand the next time she was going to try. Addison came up with a crazy plan that included a lot of fertility drugs. She wanted to try again with fresh sperm and fresh eggs, even though she had two frozen eggs left herself. Addison took Sam to therapy with her as he needed to face there would be a baby in her life soon, but he said that was not a problem yet and that he wanted Addison. Two weeks later, Addison collapsed at the practice as a side-effect to the hormone treatment. That made her decide that the embryo transfer would be it: she'd either be pregnant or not. After she was fully recovered, they did the transfer. On Thanksgiving, Addison did a pregnancy test.The Breaking Point, 5x09 (PP)
===Alternate Reality===
In Meredith's dream, Derek and Addison are still in an unhappy marriage and Addison is pregnant with their child, though the child is later revealed to be Mark's. Also, Addison is still part of the surgical staff at Seattle Grace Hospital and remains the OB/GYN and neonatal head.
===Adopting Henry===
Mere hours after delivering a baby at St. Ambrose Hospital, Addison got a call from her social worker saying that a birth mom had chosen her. She returned to the hospital, shocked to find that it was Judi, the same woman whose baby she had delivered. Judi had decided she couldn't find a better mom for the baby, and that it must have been fate since Addison was the one who delivered the baby boy. Addison named him Henry Montgomery.
===COVID-19 Pandemic and Uterine Transplant Research===
Addison lost her way during the pandemic. Two months into the first lockdown, Jake and Henry were bickering about Game of Thrones and Addison couldn't bear it anymore, seriously considering to leave Jake. She got up off the couch, got in her car, and started driving for two hours before she stopped and asked herself what she was doing. Addison started to over-indulged in wine. Henry became obsessed with video games and Jake took up a model train hobby, which truly delighted him much to Addison's surprise. She grew increasingly uneasy spending so much time at home and at one point even considered checking herself into rehab for her drinking habits. She went even darker and started daydreaming about going to sleep and never waking up, which comforted her. Eventually, she came up with a research project on uterine transplants and met Tovah Freedman. The drive to help Tovah motivated Addison to pull herself back together and get out of bed every morning.
As part of her research, Addison eventually travelled to Seattle to perform a uterine transplant on Tovah, who had her support system in Seattle. Addison reached out to Richard if there was an OR available for her and agreed to make her return a grand rounds teaching opportunity for the residents, whom he mentioned were behind. On the day of the surgery, Seattle was going through a heatwave.
Addison arrived at the skills lab to introduce herself to the group of residents. En route to the patient, she explained her research and quizzed Levi on the pelvic anatomy. When he answered correctly, she allowed him to present the case and upon seeing a connection between him and the Jewish patient, she chose him to scrub in with her along with Richard. The other residents gathered in the gallery to observe and Addison kept them engaged with a multitude of questions. In the middle of the procedure, the HVAC system broke down. The temperature in the OR quickly rose yet Addison refused to close up the patient despite Richard's warning about the risk of infection. To work faster, Addison requested Meredith due to her experience with microvascular anastomosis of the abdomen. Meredith soon joined her in the OR and they congratulated one another on their professional accomplishments. As they operated, Addison asked Meredith what big thing was next for her. Meredith revealed that she had some idea but she needed to sort out things logistically and have a difficult conversation with Richard. After evacuating a clot, Meredith and Addison successfully finished the procedure. As they left the OR, they heard the residents gossiping about the tension between them.
However, once alone on the elevator with Meredith, Addison broke down crying because coming here made Derek's death all too real for her. Meredith said he was there and in her kids is well, whom she invited Addison to meet over dinner at her house. Addison then told Meredith to fight for this big project if she believed in it, stating Meredith had never been one to shy away to fight for what she loved.
Afterward, Addison went to check on Tovah in the ICU. Everything was well. Richard congratulated her and Addison told him the residents were not as bad as he had made them out to be. He couldn't help but point out the difference between the current generation and Addison and Derek's generation, stating the current residents complained a lot. Addison pointed out they were simply standing up for themselves and refusing to be worked to death in a system that could be considered inhumane. She considered that progress and stated there was always room for improvement in the medical education system. He agreed and told her he was glad to see her again. Addison then finally met up with Amelia in the lobby. After a long hug, Addison told her about Meredith's invitation. Amelia took her home and introduced her to Zola and Bailey. Addison got emotional upon meeting them and sat down with them to have ice cream for dinner.Hotter Than Hell, 18x03
The day after, en route to the airport, Addison was notified that Tovah had had a seizure in the ICU. Addison rushed back to the hospital and enlisted Amelia's help to figure out what was causing the seizures. Addison was panicking because Tovah's sister had begged her not to participate in the trial and it could mean that they would have to remove the uterus, meaning all had been for nothing. As they awaited the MRI scan, Amelia confided in Addison as to why she had left Scout's father. Upon hearing that Amelia had struggled so hard during the pandemic, Addison relayed her own experiences, which comforted Amelia. Eventually, they found that the seizure had been due to neurotoxicity from the anti-rejection medication. They decided to switch the meds and start anticonvulsants. Addison needed Amelia to tell her that Tovah would be okay as she absolutely prioritized Tovah's life over her study. Amelia pointed out that Tovah had loved her husband so much that she entered Addison's trial, very much aware of the risks it entailed. Tovah recovered in the ICU and Addison happily informed her that there was still a chance for her to have her husband's baby. On her way out, Addison recalled her frustration with Jake and posed that a slight mental health crisis doesn't make for good decision making. Amelia stated she stayed with Link through the pandemic because she deemed herself crazy to leave a good guy but she wasn't feeling crazy now nor did she feel the need to get high; she realized she just didn't want a ring or more babies, so she thought it the kindest and sanest thing to let him go. Addison smiled and commented that Amelia was all grown up now.With a Little Help From My Friends, 18x04
===Pro-Choice Advocacy===
Following the overturning of Roe v. Wade, Addison's practice in Los Angeles became slammed with out-of-state patients seeking abortions due to the new laws in effect. She returned to Grey Sloan to seek the help of Bailey and the new interns to make sexual education videos to put online, such as facts about STIs. While there, she assisted Lucia Castelino in seeking an abortion, and scrubbed in on Diamond Thompson's ovarian cyst resection.Let's Talk About Sex, 19x03
After Bailey gave Addison Grey Sloan's mobile surgery unit, she used it to travel to Illinois to help patients seeking abortions living in hostile states. This garnered the attention of anti-choice advocates, who started to stalk her and doxx her, publishing her home address and phone number on the internet.
Addison returned to Grey Sloan to help Bailey train new OB fellows. After it was published online that she'd be at the hospital, a mass of protesters gathered outside the clinic. The protests became violent after a protester threw a brick through the window with the words "Montgomery murders" written on it. She helped to deliver a baby while security helped to disperse the protesters. However, when Addison and the rest of the team were being safely escorted from the clinic, a protester ran a car into both her and a pregnant OBGYN trainee.Training Day, 19x11

==Relationships==
===Romantic===
====Derek Shepherd====
Addison met her future husband, Derek Shepherd, in medical school in the summer. Their relationship grew and they eventually married. Derek once wrote a song for her.
After medical school, Addison and Derek became extremely successful in their respective fields and each began their own practice in New York. However, this strained their marriage.
Addison was married to Derek Shepherd for eleven years before eventually sleeping with Derek's best friend, Mark Sloan, which prompted Derek to leave New York for Seattle at the request of their old friend and mentor, Richard Webber.
After she and Derek initially separated, she tried to get over him, even hoping that dying her hair blond would help. She remained in New York and lived with Mark for two months, during which she became pregnant with Mark's child but she chose to have an abortion. The relationship ended when Mark cheated on Addison and Richard Webber brought her to Seattle Grace for a consult on a difficult case.
After a period of antagonism between her and Derek (in which he continually referred to her as "Satan"), Addison decided to stay on as the Head of Neonatal Surgery and OB/GYN at Seattle Grace, signing a two-year contract after she and Derek decided to make an effort to work things out. Addison was unaware that Derek still had feelings for Meredith.
When Addison discovered that her husband slept with Meredith at the hospital-sponsored prom, Addison (in a drunken haze) called Mark Sloan to Seattle. She and Derek agreed that their marriage was over and started divorce proceedings. She asked Mark to go back to New York, but he stayed, expressing his desire to continue their relationship.
When the divorce was finalized, Addison dropped the "Shepherd" from her last name. Wanting to make a fresh start, Derek happily relinquished most of their shared properties (their Brownstone in Manhattan and a residence in The Hamptons) to her believing that she deserved it as his initial impression was that she had only had a one-night stand with Mark while he carried on an affair with Meredith.
====Alex Karev====
She stayed in Seattle for a long while after and a possibility of a relationship between her and Alex Karev was hinted at when they kissed in Joe's bar. She felt it was too strange though and he said he didn't care so the relationship was not brought ahead any further.
During the 60 days that Mark and Addison were trying to remain celibate to give themselves a chance, she slept with Alex. However, despite Addison wanting more, he wasn't ready for that.
====Mark Sloan====
 Addison and Mark originally met in med school. She cheated on her husband, Derek, with him. After Derek left for Seattle, Addison and Mark lived together for two months, during which time she became pregnant. She had an abortion, and Mark eventually cheated on her.
After finding out Meredith and Derek slept together at the prom, she called Mark over to Seattle and slept with him again. Mark decided to move to Seattle in hopes of pursuing a relationship with Addison.
On the first anniversary of the day she discovered she was pregnant, Addison and Mark made a deal. If they both could abstain from sex for 60 days she would be willing to try a real relationship with him. She doesn't hold up her end of the bargain when she engaged in a sexual encounter with Alex at the hospital. Mark learned of this after witnessing them stumbling out of an on-call room. She was spared from confessing, however, when Mark selflessly lied to her by telling her he had broken their promise long before. He felt that although he had feelings for her, she shouldn't have to feel guilty.
Mark visited Addison in LA when his daughter, Sloan Riley, needed surgery. They had sex several times, which prompted Addison to ask Mark if he truly wanted to have a relationship with her because she could make it work. However, Mark was still in love with Lexie, so he apologized to Addison and turned her down.
====Pete Wilder====
 When she left Seattle Grace Hospital for a private practice in L.A, she had a brief interest in her co-worker Pete (whom she kissed) but gave up on any potential romance between the two after Pete stood her up for a date.
Later, Pete and Addison reconnected at a hospital event and went back to her house to have pizza and watch lame TV shows, and ended up having sex. They started a relationship that they described as "helping each other" and Addison decided to move on from Sam since he was seemingly happy with his new girlfriend, making them officially a couple.
When Pete was sick and Addison was looking after Lucas, Pete said "I love you, Violet" to Addison while on fever medication, leading Addison to confront Pete six weeks later. Pete states that he will always love Violet as she is the mother of his child, but he wants to be with Addison. 
Violet returns from Costa Rica and Addison tells her that Pete will pick her because she is Lucas' mother. 
Later on the porch, Sam tells Addison he is sick of doing the right thing and should do the wrong thing, and then kisses her as Pete walks in. 
====Kevin Nelson====
 Addison was then asked out by Kevin Nelson, a police officer. Unfortunately, her trust issues interfered with her and Kevin, issues that resulted in her jealously following Kevin after she thought he was having an affair and ending with her arrest by the SWAT team. Nonetheless, she confessed her issues to Kevin and they resumed their relationship.
But more troubles came when Addison's brother came to visit and told Kevin that she was just "enjoying him". When he hadn't called Addison back; she had thought he was avoiding her, but would find out he had been shot. When her brother left; Kevin moved in with her while he was recovering. While Addison now had to deal with Charlotte who was opening up a competing practice on the fourth floor, she was more annoyed by Dr. Wyatt Lockhart, a doctor working for Charlotte's practice who steals a patient of Addison's and convinces Naomi to work for her. In the midst of this relationship, Addison and Kevin's different lifestyles get in the way of their relationship leading to him moving out. But Addison later calls him telling him she misses him, and they make up.
However, Addison kisses Wyatt after seeing him for who he really is, not the arrogant, headline grabber she thought he was. Kevin repeatedly questions her where she was that night and believes she's lying, Addison claims she was working, and just as Kevin was finally able to drop the questioning, she admits she kissed another man, and they break up. As Addison goes to Wyatt to try a new relationship, she catches Naomi having sex with Archer instead.
====Noah Barnes====
Noah and Addison frequently met in the scrub room over three months, one of them always finishing surgery and scrubbing out and one scrubbing in, leading to their greeting of "Finishing or starting?". They both continued to flirt, not knowing each other's names, and eventually meet in the doctor's lounge where Noah asks for her name. Looking shocked, he quickly leaves.
Addison later meets him as the husband of one of her pregnant patients, Morgan Gellman. Upon this discovery, Addison quickly removed herself from Morgan's case, as she was not comfortable with her feelings for Noah while she treated his wife, feelings which Noah reciprocates. Addison decides not to make a move in their relationship, refusing to be a homewrecker, after her past mistakes with her ex-husband and his best friend. Noah, however, asks her not to leave the case, as she is the best in her field and Morgan cannot lose another child (she had a string of miscarriages before seeing Addison), and he will keep his feelings for Addison in check. However, Noah cannot help the way he feels, and Morgan realizes her marriage is in jeopardy, asking Addison to save her child, as that is all that is keeping her and Noah together. She says she sees it in Noah's eyes, he's there, but he's not quite there. When Addison has to perform surgery on Morgan, Noah is not there for her and Morgan is willing to put off the surgery to have Addison find Noah and he eventually does go into the OR to be there for Morgan, with a push from Addison.
====Sam Bennett====
Sam asked Addison out when they were in med school, but Addison declined because Naomi was in love with him. When Addison moved to LA, she bought the house next door to Sam, leading to their developing friendship. 
Addison and Sam kissed after a hiking experience gone wrong while discussing what would have happened had Addison said yes to Sam in med school. They kissed twice more and Sam propositioned Addison to develop their relationship, but Addison said no because Naomi was her best friend.
Sam dated another Neonatal surgeon, leading Addison to date Pete, although she still loved Sam, and she is seen constantly talking about him to Pete. Sam and Addison had an off and on relationship for a long time.  
The main reason for their relationship troubles was that Addison wanted a child, but Sam had Maya, and Maya's daughter, and didn't want more kids. After Addison adopted Henry, Sam seemingly accepted Henry. He even asked her to marry him after Addison and Jake had had sex. 
====Jake Reilly====
When Addison's therapist told her to make a change in her life, she met Jake and they flirted over pineapples at the grocery store. They started seeing each other at a coffee shop. However, they both agreed to keep their identities in secret. Jake was going on vacation to Fiji and he asked Addison to come with him. She eventually accepted, but when at the airport, she realized it wasn't right to try to avoid Sam and the problems the practice was suffering.
 Later on, Addison started her fertility treatment only to find out her doctor was Jake. He admitted he never left for Fiji. Addison, humiliated, left the office.
When Jake interviewed for the fertility specialist opening at Oceanside Wellness, Addison was horrified because she recognized him as her former doctor. She was strongly opposed to the practice hiring him, but she ran out of excuses not to, as he was the perfect candidate for the job. Jake began working at the practice, and Addison made him not mention their previous encounters to Sam, who she was dating at the time of Jake's arrival.
Addison began fertility treatments with Jake as her doctor. He helped her through her two failed IVFs and also to try to find a surrogate.
She once threw herself at him at an OB/GYN convention in Palm Springs. She was extremely drunk and stumbled into his hotel room, where she asked him if he wanted to sleep with her. He turned her down, saying that it was the alcohol talking and that she would regret it in the morning. When Addison woke the following morning, she remembered what had happened and was thoroughly embarrassed.
Jake once asked her if their relationship was purely physical because he cared about her, but she was sending him mixed signals. Addison confirmed that it was not just physical, but also emotional. Their relationship grew over time. When Jake was talking to his daughter, Angela, he told her that it wasn't Addison sending the mixed signals; it was him.
Addison proposed to Jake shortly before Henry's adoption, and was thoroughly humiliated when he didn't answer; but after a talk with the ghost of his late wife, he accepted. They later got married.
===Friendships===
 Since arriving at Seattle Grace Hospital, Addison has made many friendships with other hospital staff, most notably Callie Torres and Miranda Bailey (Miranda's reasons being that Addison smells nice, she's polite, and she saves babies). Her friendship with the two ladies has often been based on the fact that they act as each other's confidantes. Callie and Addison often discuss their current relationships and love lives, which has ultimately led to a very close friendship between the two. Addison is also very good friends with fellow attending, Preston Burke, and her ex-husband, Derek Shepherd. She had a good friendship with Mark Sloan and a father-daughter bond with Richard Webber as she is often portrayed to be very close to him. The only intern that Addison really bonded with was Alex Karev but she had no grudges against any of the interns and even hugged Meredith as a sign of acceptance of her relationship with Derek. She helped inspire Izzie to become a fighter again.
Addison is believed to have had a good relationship with the Shepherd family, in particular, Nancy Shepherd, but, pending Derek's revelation of the true extent of Addison/Mark's relationship, her closeness to the Shepherds is in doubt.
After moving to L.A., Addison returned to Seattle Grace Hospital to help with a patient whose fetus’s heart was growing out of its body. Upon her return, Addison didn't expect much change; but soon learned that since her departure a lot had changed - for example, the break up of Meredith and Derek and his relationship with Rose, Callie's divorce and the breakdown of Bailey's marriage. During her stay there she met Callie's new friend Erica Hahn and mistakenly interpreted their friendship as a relationship. The mother and child both survived the surgery and Addison prepared to leave Seattle and return to L.A, telling Richard that she needed to come back to see how much she liked her new life. She left, but not before finding Meredith and telling her that she wasn't allowed to let Derek get away.
Addison betrayed Naomi by confronting Sam with something about the practice. Naomi dropped her friendship with Addison and refused to talk to her. Eventually, she and Naomi began to mend their friendship and at last came back to being best friends. Addison (despite her rocky start) got on well with her new colleagues and friendships were rekindled (as she was friends with Naomi and Sam years ago), friendships were started (Violet, Dell, and Coop) and even a short time relationship occurred (with her now friend, Pete). When Naomi left for New York, Addison and Violet became very close, discussing relationship woes and Lucas situations, and just generally they were pretty close. When Amelia came to L.A., she and Addison had a very sisterly relationship.
==Career==
Addison is considered one of the best surgeons in her field in the world, having patients travel across the country to receive medical and surgical care from her, helped by her excellent bedside manner. She formerly worked at Seattle Grace Hospital, before her relocation to Los Angeles to join a private practice. When she relocated, her surgical practice became limited, with her practice being mostly obstetric work and occasional genetic counseling with Naomi. However, she does have surgical privileges at St. Ambrose Hospital, allowing her to conduct her own surgeries, which is a right she exercises frequently. Charlotte King also calls on Addison to consult and take on complex medical cases from the hospital, which increases her OR time.
She completed her surgical residency under the supervision of her now good friend, Richard Webber. During her residency, Richard gave Addison a patient who would not survive, to teach Addison to not get too emotionally involved with her patients, as a result, Addison avoided Richard for almost a year. As an attending, she repeated the same trick with Izzie Stevens and one of the quintuplets the hospital was taking care of.
During her OB/GYN residency, Addison was mentored by Dr. Vivian Carlsmith, a world-renowned OB/GYN , and pioneer in maternal-fetal medicine. Addison was Vivian's smartest student, eventually surpassing Vivian's skill.
Addison's training also encompasses why she is regarded as one of the best surgeons in her field: she is board certified in obstetrics and gynecology with her sub-specialty in maternal-fetal medicine, board-certified in neonatal surgery, and has completed a fellowship in medical genetics, specializing in cystic fibrosis. She is very open about her credentials and has relayed them to patients, co-workers, and subordinates that have doubted her abilities.
Surgically, she is highly skilled in complex, often laparoscopic and open, obstetrical, gynecological, neonatal and fetal surgeries. She is one of the few surgeons in the world who can separate fetal blood vessels and correct Twin-to-twin transfusion syndrome, which she has special expertise in. She was formerly the attending surgeon in charge of a world-class NICU and state-of-the-art OB/GYN wing at Seattle Grace Hospital. Although a highly successful and well-paid job, Addison left Seattle to go to L.A to join a private practice.
When she arrived at the practice she was surprised to discover that Naomi, who gave her the job offer, didn't tell the rest of the staff about Addison. The other doctors showed Addison that she was clearly not welcome. On her first day in the practice, she performed surgery in an unsterilized delivery room only with the help of Alternative Medicine Specialist, Pete. On the end of the same day, they decided to vote on whether Addison should join the practice or not but Addison put her foot down and told them that she was going to stay even if they wanted her gone. Everyone was impressed by her speech and they decided not to vote after all.
When Richard Webber asked Addison to return for a complex surgery, she agreed, and at the end of the day, Richard attempts to get her back and letting her start the next morning. Addison declined the offer, being sure that leaving was the right thing to do. Similarly, when Naomi would not speak to Addison, Addison took several surgeries at St. Ambrose to relieve her frustrations. Charlotte tried to woo her to the hospital with the surgeries but Addison declared the practice as her 'home'.
Not long after moving to Los Angeles, Addison learned that the practice was failing financially so confronted Sam and the two formed a hostile takeover. In a bid to get the practice back to how it used to be Addison accidentally prompted a vote between Sam and Naomi, but was stunned when she was elected to lead the practice as Addison's leadership shone through.
Later, Addison dissolved the practice, funded the change, and renamed it to Seaside Health and Wellness.
==Notes and Trivia==
*She was 39 when she moved to Los Angeles.Didn't We Almost Have It All?, 3x25
*When Derek left her in New York, Addison dyed her hair blonde.Walk on Water, 3x15
*Since moving to L.A, Addison describes herself as very zen. She buys aromatherapy candles and takes walks on beaches.
*When she worked at Seattle Grace Hospital, her salary made her one of the highest-paid surgeons in the Northwestern United States.
*Addison performs abortions. She believes life only begins when the baby can survive outside the mother's body, thus at birth.Crime and Punishment, 2x08 (PP)
*During her education, Addison always hated neuroanatomy.
*Addison's SGH ID badge stated her departments were Obstetrics and Gynecology and Neonatology.
*Addison sometimes wears reading glasses.Staring at the Sun, 3x08
*She has a lucky scrub cap.
*Addison has a very close sisterly relationship with Amelia Shepherd, as Addison took her to get her ears pierced, she did her hair for prom, and she explained to her how to use birth control when Amelia didn't know who to ask.Who We Are, 5x08 (PP)
*Before she was officially a part of the Seattle Grace Hospital attending staff, she wore salmon scrubs. Whether or not she owned these scrubs or if she was wearing the uniform color of OB/GYNs remains unclear. Kate Walsh stated in an interview that it was decided to let Addison wear the navy blue scrubs to make her more part of the attendings group.
*Whenever Addison wants to tell something that she cannot tell, she stares at the person she wants to tell.
*Addison and her family are WASPs - they only go to Church on Christmas, and she does not know how to pray.Before and After, 5x15
*Addison rarely mentioned being a WASP during her time as a series regular on Grey's Anatomy but talked about it quite often in Private Practice. However, when she mentions it in GA, she is referring to the Protestant aspect, whereas she mainly uses the term in PP to discuss the culture of her childhood and family, in the social group aspect.The Parent Trap, 3x09 (PP)
*It has been noted that Addison's qualifications are unrealistic for a practicing doctor in her late-30s/early-40s, as she has already gained a highly-regarded reputation at her character's introduction to the series. Since Derek and she attended medical school together and were both educated by Richard Webber, it is likely she completed a 5-year residency in general surgery followed by a 2-year fellowship in pediatric surgery focusing on neonatal and fetal surgical procedures, returning to complete a 4-year residency in obstetrics and gynecology followed by a 3-year fellowship in maternal-fetal medicine, with her (likely to be) 2-year fellowship in medical genetics following everything else. In reality, under the best circumstances, this would make Addison a minimum of 40 years old.
**It has been indicated throughout seasons five and six of Private Practice that Addison first completed a residency in OB/GYN. This would mean that she followed up with fellowships in maternal-fetal medicine and medical genetics, then completed a general surgery residency and finished with a pediatric surgery fellowship focusing on neonatal and fetal surgeries. If this is indeed the case, this creates a continuity-error with her being mentored by Richard, as stated in Grey's Anatomy, as OB/GYN residents do not rotate in other surgical departments; this would be plausible if Richard were somehow involved in Addison's OB/GYN residency.
*Addison appeared in every single episode of Private Practice, except for Two Steps Back and The Hardest Part.
*Although incorrect, Dr. Jake Reilly referred to Addison as a neonatologist.Don't Stop 'Till You Get Enough, 5x07 (PP)
*Addison is the first and last character to be seen on Private Practice. The first scene of the show is her talking to Richard about her resignation, and the last scene of the show is the group talking in the kitchen in the practice, with her face being the last one to be seen from inside the elevator before its doors close completely.
*In one college semester, she took classes in Organic Chemistry, Physics II, Multivariable Calculus, Conversational French, Introduction to the Modern European Novel, and Tennis. She later had to retake tennis due to getting an incomplete.Too Much, 5x14 (PP)
