As if it's not enough that Cristina Yang was left at the alter by the last cardio doctor, bring on the new competition-Erica Hahn. Cristina just wasn't getting beat on yet this season, I guess. Dr Hahn really lets Cristina know where she stands up front telling her that she can't sleep her way to the top this time aroung. She is not about to give Cristina respect just because she's Crisitina, she's going to have to earn it. Dr. Hahn has made it very clear to us that the cardio-surgeries do not belong to Cristina. So many strong women, so many potential fights for the rest of the season. I knew Cristina wouldn't take it without a fight. She takes the first chance she gets to throw it back at her calling Dr. Hahn on the carpet for being "inappropriate" and "unprofessional", but it will come back to bite her. Cristina's gonna have to step up her game with this one and change her moves if she's gonna make it with Hahn. Hahn lets Isobel Stevens scrub in on the surgery instead-much to Cristina's dismay. What the heck is she doing asking Izzie to help, though? Izzie's a mess still. Maybe Hahn will knock some good sense into Miss Bambi Saver.
