Castle: (about the cameras) Come on. What's the big deal? It'll be fun.
Beckett: Look, Castle, what I do here, this is... mine. And just because they want to invade my privacy, it doesn't mean that I have to help them do it.
Castle: Okay. That may be. But... these cameras, they're not going anywhere. They're gonna see something. I just want them to see what I see.
