when does arizona find out karev cut off her leg
One Flight Down (Grey's Anatomy) Alex sticks close to Arizona to make sure that sheâ€™s okay, but she finds him more annoying than helpful. Alex tells Arizona that it was he who cut off her leg, not Callie. When asked, Callie tells Arizona that she was the one to make the call anyway, and she wanted her to have Alex and just be mad at her alone.
