Leah Murphy, Grey’s Anatomy
Leah Murphy (Tessa Ferrer)
On Grey’s Anatomy, surgical intern Leah Murphy was introduced in Season 9 when she slept with pediatric surgeon Alex Karev and developed an infatuation with him. Her fellow interns characterized the relationship as obsessive and one-sided, so she worked to get over her feelings.
Leah then began sleeping with Arizona Robbins after Arizona’s marriage to Callie Torres fell apart. Arizona did her best to keep the relationship casual because of Leah’s reputation of becoming overly-attached and because the breakdown of her marriage was so recent. Arizona ended the relationship with Leah when Callie wanted to try and reconcile, and Leah was left heartbroken. Leah eventually filed a suit with the hospital HR due to Callie’s mistreatment of her while on her service, though Leah was ultimately fired for not being cut out to be a surgeon, and left the series after Season 10.
Tessa Ferrer came back to the show in Season 13, part of the recurring cast, and she appeared in 6 episodes (13×06, 13×07, 13×09, 13×11, 13×12 and 13×13). After leaving in season 10, Leah worked at Foster Hospital, spent her time improving and working harder than ever, and discovered she wanted to be a cardiothoracic surgeon and study under Maggie Pierce, which was the reason she had come back.
Her time in season 13 was mostly spent on various cases, and working under Maggie Pierce or assisting Arizona.
