Castle: Swan eluded his cameraman to go on a clandestine errand, an errand so important, he missed a band meeting. He was acting erratically, went to the bank right beforehand. This all points to one thing.
Beckett: That's an interesting theory, but that is pure speculation.
Castle: Actually, it's not. Pure speculation would be Swan purchasing thermonuclear technology to have a scientist make him an amplifier that went all the way to 12. This, musicians buying drugs, that's just Monday morning crossword.
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.
