Grey's Anatomy, Season 8

Meredith:
I think I stole a baby.

Cristina:
Okay, first of all, you didn't steal the baby, she's your baby. What you did is... You took her for a nap... in a very odd location and you failed to answer your phone. But y'know, many people find all the technology in our lives to be intrusive, so you're not the first person who didn't answer your phone or your pager. You know, all we have to do is- is find a reason why you were AWOL for an hour.

Meredith:
Four... hours. [Cristina glares] Janet was gonna take the baby so I took off.

Cristina:
Okay, okay. You know, people make mistakes. I mean, I almost killed Alex in the OR today, so we'll just figure it out.

Meredith:
How?

Cristina:
I don't know.

Meredith:
No, how'd you almost kill Alex?

Cristina:
With a cc of epi. [Meredith looks shocked] Ah, y'know, whatever. He'll be fine. Just uh-- stay here. I'll fix this.

Meredith:
What are you gonna do?

Cristina:
I'm gonna fix it.
