Nate: Did you sleep with her, huh? You son of a bitch, I could kill you.
Chuck: Could we talk about this without your hands around my neck?
Nate: What did you do, did you get what you want like all those other girls?
Chuck: Yes, Nathaniel. I took what Blair kept throwing at you and you kept throwing back.
Nate: Oh, so somehow you screwing Blair for sport is my fault?
Chuck: It wasn’t for sport. She needed someone and I was there.
Nate: Oh, so you cared about her?
Chuck: You guys were broken up.
Nate: For how long? A week? An hour?
Chuck: Look, I’m sorry, alright. I know how long you and I have been best friends, okay?
Nate: No it’s not okay, Chuck. From now on you stay away from me.
