<P> Following the end of Private Practice, when ABC cancelled it after six seasons in January 2013, the character of Amelia was added to its progenitor show Grey's Anatomy . In Season 10, she was seen in the season's last four episodes visiting her brother Derek and his wife Meredith Grey in their Seattle home and helping care for their children . Previously, she had only made one - off guest appearances on the show when storylines crossed over between the two series . </P> <P> On June 23, 2014, Scorsone and her character was permanently added to the regular cast for Season 11, which began airing in September 2014 . </P> <P> When Derek is offered a job by the President of the United States running a federal brain - mapping research project in Washington, D.C., Amelia, having begun assisting at Grey - Sloan Memorial Hospital with some of Derek's patients, takes over his practice, as the head of neurosurgery, at the hospital . She thus gained monikers, such as "Shepherdess" and "Lady Shepherd," so as to differentiate her from Derek . By season 11, she permanently moves in with her brother and her sister - in - law . Initially, she is known at Grey - Sloan largely as Derek's younger sister and once told her brother that she felt like she was constantly in his shadow . She soon begins a relationship with Owen Hunt (Kevin McKidd), her boss, and admits to Derek that she is falling in love with him . However, she later tells Owen that it was a mistake to mix their personal and professional lives . Following her brother's death and Meredith's "disappearance," she buries herself in work to distract herself . For some time she and Meredith were estranged over the circumstances of Derek's death but after listening to the very last phone message Derek had recorded for Meredith, she is finally able to let go of the animosity and reaches out to Meredith . Meredith's half sister Maggie moves in, with Amelia labeling the threesome "Lady Chief Trifecta ." She gradually befriends Meredith's colleagues and is accepted into their circle . At the end of season 12, she marries Owen Hunt . However, the marriage is very turbulent at times . They struggle to adjust to married life, especially when Owen tells her that he wants kids as she does not want kids, nor does she want to go through the trauma of another pregnancy after the loss of her first child (who Owen doesn't know about). This strains the marriage to the point where she moves out and avoids him entirely . During the rest of the season, she grows closer to the two sisters and focuses more on her work, ignoring her stalling marriage . In season 14, when she went into an MRI as part of a study conducted by Carina DeLuca on female brain activity, she found out that she has a brain tumor . Her old mentor Thomas Koracick removes it without a problem, but Amelia is forced to step back and reconsider how the tumor had affected her life choices and personality . She and Owen end up having an understanding to break up their marriage but still remain close friends . She later assists Owen when he is chosen as a foster parent for a baby boy and bonds with the child's mother, Betty, who is a drug addict . Amelia feels the obligation to become her sponsor and the two of them move in with Owen so they can help Betty maintain her sobriety while allowing her to spend time with her son . </P>
