Cristina: Hey, I heard about really old guy. What's the matter? You couldn't find his LVAD wire?
Izzie: It was a concidence, and he's still alive.
Cristina: Well, have fun with really old guy. I'm off to do Meredith's hemiglossectomy. (laughs and walks away, Meredith sees this)
Izzie: Hey, hey, has George said anything to you --
Meredith: She's faking. She's faking sadness, pretending to be sad to steal my surgeries.
Izzie: Okay, I have really old guy trying to kill himself and problems of my own, so I don't have time for the two of you and your fake drama. (walks away)
