Burke and Cristina in “Into You like A Train”

Burke

Cristina, you paged me?

Cristina

If I don't find this leg, the chief is going to cut me from this program, and I cannot go back home, Burke. It is too sunny in Los Angeles. It's sunny every day.

Burke

You paged me because?

Cristina

I need you to help me find the leg! I checked the board, you're not in surgery, right? You're my boyfriend! I mean, I know I don't have much experience with this kind of thing but, aren't boyfriends supposed to help in situations like this?

Burke

Cristina, when we're on duty I can't be your boyfriend.

Cristina

OK, so, uh, when we're on duty, I can have sex with someone else?

Burke

[pause] Dr. Yang, I'm walking away now.
