Apples, apples, apples!
Kate: Are you here to annoy me?
Castle: I'm here for the story.
Castle: That's too easy. The reader would never buy it.
Kate: This isn't one of your books, Castle. Out here, we find a guy standing over a body with a gun, he's usually the guy who did it.
Esposito: (about Castle) The man's got the Mayor on speed dial. The rich really are different.
Kate: You want him? He's yours.
Esposito: A control freak like you with something you can't control? No, no, that's gonna be more fun than Shark Week.
Kate: No signs of struggle. He knew her.
Lanie: Even bought her flowers. Who says romance is dead?
Kate: I do. Every Saturday night.
Lanie: A little lipstick wouldn't hurt.

Castle: I'm not asking for the bodies. Just the pictures.

Beckett: Castle, you ok?
Castle: Yeah, but this psycho here needs a breath mint.
Castle: (Beckett grabs his nose) Apples! Apples! Apples!
Castle: So. Looks like I managed to make it through the case without getting injured, shot or killed.
Kate: Yeah, well, maybe tomorrow.
Kate: Okay, Castle, but it's accompany and observe, not participate and annoy. Got it?
Castle: Participate and annoy is a lot more fun, but alright.
Castle: We could always make it strip poker.
Kate: Sorry, but I prefer mystery to horror.
Castle: (to Kate about marriage) You'd be good at it. You're both controlling and disapproving. You should really try it.
Castle: Oh my god. This is quite possibly the worst coffee I've ever tasted. It's actually kind of facinatiing. It tastes like a... (pauses to sip the coffee) it tastes like a monkey peed in battery acid. Try some?
