Grey's Anatomy, Season 3

Derek:
I'm fine.

Meredith:
Are we fine?

Derek:
Sure.

Meredith:
Not so convincing. I shouldn't have accused you of hovering, it wasn't nice. You were just trying to be there for me. But now, I'm being available, communicating, getting naked, and doing all of your favorite things.

Derek:
Hm, good things.

Meredith:
Then why are you still staring at the ceiling?

Derek:
I don't know, it's just, that day, you came out of the water. I spent the scariest hour of my life, trying to breathe for you. I love you, and I want you, but I don't know what to... you didn't swim. You didn't swim and you know how to. And I don't know if I can... I don't know if I wanna keep trying to breathe for you. [pause]

Meredith:
I should go. I'll go.
