Castle, Season 1

Castle:
[to Beckett] Well, you're not bridge and tunnel. No trace of the boroughs when you talk, so that means Manhattan, that means money. You went to college, probably a pretty good one. You had options. Yeah, you had lots of options, better options, more socially acceptable options, and you still chose this. That tells me something happened. Not to you. No, you're wounded, but you're not that wounded. No, it was somebody you cared about. It was someone you loved. And you probably could have lived with that, but the person responsible was never caught. [realizing he's overstepped] And that, Detective Beckett, is why you're here.

Beckett:
Cute trick. Don't think you know me.

Castle:
[hesitant] The point is, there's always a story... you just have to find it.
