Izzie (to her interns): So, this is Cristina, Dr. Yang.
Cristina: Yep, saving lives and taking names.
Izzie (whispering to Cristina): All these interns and nothing to do. And I think that I'm a really bad teacher and they hate me. And now I'm a fraud, so any chance you wanna let me on this?
Cristina: Izzie, this guy was dead, and now he's undead, so that kinda makes him like a zombie. And my personal zombie, so no you can't get in on this. Now you can go be a (loudly) fraud, somewhere else.
Izzie: I don't like you.
