Mr Daniels Paradox...

Sam: Okay. Well, the truth is... actually... I'm in love.
Daniel: Aren't you a bit young to be in love?
Sam: No.
Daniel: Oh, well, okay, right. Well, I mean, I'm a little relieved.
Sam: Why?
Daniel: Well, because I thought it would be something worse.
Sam: Worse than the total agony of being in love?
Daniel: Oh. No, you're right. Yeah, total agony. Tell her that you love her.
Sam: No way. Anyway, they fly tonight.
Daniel: Even better! Sam, you've got nothing to lose, and you'll always regret it if you don't.

For better or for worse... we'll always have Jack...
