"Take care now"

Grey Anatomy Season 5 Episode 21: Not Good at Saying Sorry

Hunt: ... I didn't do anything wrong today. I treated you like i would anyone else.

Yang: No. Not like anyone else! "Take care now"? what is that?
What are you - like, you know - happy now?
What are you? You know, just a "choke 'em and forget 'em" kinda guy?

Hunt exhaled and handed a paper to Yang

Yang: "Hey there now, take care now, nice work yang." What is this?

Hunt: It's my shrink. My shrink gave me these sentences - we came up with them together. They're all 3-word sentences so i'd have to say to you instead of the 3 words that are... that are killing me. The 3 words that you know i feel but i can't say them, because it will be cruel to say them because i am no good for you.

I don't wanna torture you.
I don't want to look at you longingly when i know i can't be with you.
So yeah, I'm smiling and i'm saying "take care now".
I'm letting you off the hook. I'm trying - trying so hard to let you off the hook. I'm trying to make it right - what i did to you. Can't you see that? I'm just trying to make it right.

Yang, crying and heartbroken, handed the paper back to Hunt.

Yang: Take care now..

and she left.
