Calliope 'Callie' Torres

An attending Orthopaedic Surgeon, Callie was once married to George O'Malley, but later divorced after he developed feelings for Izzie Stevens. Later, she had a lesbian affair with Erica Hahn which was cut short by Hahn's departure from Seattle Grace. She was in a happy relationship with Arizona Robbins but they broke up because Arizona did not want to have kids. At the end of the 6th season, however, after doing a surgery on a small girl while a shooter is loose in the hospital, Callie tells Arizona in a round about way that she loves her and the two end up getting back together and decide that they are going to have children
