Cristina (after her phone goes off): Oh, that's Owen. Duty calls.
Meredith: Are you two talking yet or is it just sex?
Cristina: Not just sex. Hot, dirty, stand on my head sex.
Meredith: I'll take that as a 'no'.
Cristina: Come on, who cares if we talk. Besides, if you wanna talk about somethin', how about the fact that you're wasting your fifth year playing around with vaginas and mice, huh? Wanna talk about that?
Meredith: Do you really stand on your head?
Cristina: I'm very talented.
