I didn't open this place to make money. I opened it for the exciting cases.

Alexis: I can't leave you alone for five minutes.
Castle: Does this mean no hug?

I am so sick of people pushing me away for my safety.

Castle: This novel writes itself.
Ryan: Then tell us what happens next.
Castle: I have no idea. That's what makes it so good.

You know Beckett asked for some time so I'm just giving it to her every day. Sometime twice.

This is why I love the 12th precinct. You guys never let me down.

Kate: Now Rick, be charming but not too charming.
Rick: That's like asking Superman not to be too super.

Ryan

Beckett, I think your crime scene's making a run for it.

Martha: I told you, if you can't tell your mother what you're doing you should not be doing it.
Castle: Yes, when I was eight.

It's all come crashing down around my ears and I've got no one to blame but myself.

Beckett
