Two seasons before Capshaw left Grey’s Anatomy, Arizona and Callie Torres (Sara Ramirez) fought for custody of Sophia. Callie wanted to move to New York City with Penny Blake (Samantha Sloyan). Then Arizona won sole custody of their daughter. But even so, Arizona and Callie realized they both deserved to be happy. So they decided Sophia would split time between Seattle and New York City.
In Grey’s Anatomy Season 14, Arizona realized Sophia was having a difficult time adjusting to bi-coastal living. Sophia missed her friends, school, and mom back in New York. Then in a turn of events, Arizona got the opportunity to start a new women’s health center alongside Nicole Herman (Geena Davis). So, Arizona moved to New York.
Now, it’s also possible Arizona and Callie got back together on Grey’s Anatomy. In Capshaw’s final episode, Arizona admitted she couldn’t stop smiling while texting Callie about the move. But the couple’s relationship status has yet to be confirmed by the show.
