Castle, Season 3

Castle:
Tell me you've arrested Gates

Beckett:
Not even close. I mean, I don't know how, Castle, but he killed Kim Foster and he's gonna do it again.

Castle:
There's been no developments? Usually you call me with news. [He stops in realization, his eyes grow wide. Beckett cringes, knowing she's been caught] You called to seek my council!

Beckett:
[Very slightly sheepish] I wouldn't say it exactly like that...

Castle:
No, no, no! You're hoping I had some wild theory. Some sort of penetrating insight that would lead us to a breakthrough.

Beckett:
Well... do you?

Castle:
[Stops, as if trying very hard to come up with something. Exhales exasperatedly] Gah! I got nothing.
