Castle, Season 6

Ryan:
Let's say Hank did embezzle money and killed Charlie to silence him. Why are the feds involved?

Castle:
Well, maybe it has something to do with the Russians

Esposito:
Well, if we knew the feds' angle, we'd have a leg up on solving this.

Castle:
Sorry guys. I've yet to come up with a crazy, genius theory yet. [Realizes Ryan and Esposito had stopped walking]

Ryan:
You don't need to. Not when you can go directly to the source.

Esposito:
Get Beckett to give us the lowdown.

Castle:
Okay, wait a minute...

Ryan:
We get much-needed case information, you get to clear up any lingering doubts about your loyalty. Everybody wins.

Castle:
Okay, guys, no, I can't do that, all right? After D.C., we promised we wouldn't-

Esposito:
We did you a solid getting you on this case, Castle. It's time to pay up.

Castle:
Guys, this is my fiancée, okay? What does it say about our future if I keep pushing the boundaries?

Ryan:
Castle, you whole relationship is built on the foundation of your boundary-pushing.

Castle:
...Good point.
