Grey's Anatomy, Season 6

Derek:
[seeing April covered in blood] April, what is it?

April:
Did you know I grew up on a farm?

Derek:
What happened?

April:
I... I grew up on a farm, so you know, blood... blood doesn't bother me, I... I slaughtered a pig once. That was a lot of blood. 'Bleeding like a stuck pig.' That's a saying. To bleed like a pig, you know, it means something. But you don't think of people as having that much blood. I mean, you learn in med school how many pints we all have in us, but you don't realize it until you see it. You don't get how much blood... And a skinny person? I mean, my God, Reed, she's like almost anorexic. She's like, five pounds, you wouldn't think she'd have that much blood in her, but she did. She did.

Derek:
[trying to interrupt her] April, April, April! You're in shock. It's alright. Tell me what happened.

April:
Reed's dead. Someone shot her.
