Danny: (when Brownlie revives from nearly asphyxiating) You know where you are, don't you, you son of a *****? You're in Hell, and you know what? It's full of cops!
Noel: (referring to his career as a traffic cop) You want yo know why I left?
Danny: No. (sees how disappointed Noel looks) So why did you leave, then?
Noel: (giggling conspiratorially) Well I kept being told that I looked like the guy from The Village People- you know, the gay band that dress up.
Danny: Noel, from time to time, we're going to be going out together...
Noel: (interrupting) I'm straight!
Danny: On stakeouts, for chrissakes!
Noel: So, Maddock told you I was a traffic cop?
Danny: Yeah, he did.
Noel: And you don't hold it against me?
Danny: No, Noel, I don't hold it against you that you were a bloody snake.
Noel: Well, there, you do!
Danny: (rolls his eyes) No.
Danny: (as he and Jane share a moment) Nothing ever stays the same.
Jane: That can be a good thing.
