You know Beckett, she keeps it close to the vest.

Esposito

Kate: Look I signed up for this when I put that badge on. You didn't. It's not your fight.
Rick: The hell it isn't. I don't run around you just to annoy you, I don't write up murder scenes in the middle of the night to satisfy some morbid curiosity. If that's all this was I would have quit a long time ago.
Kate: Then why do you keep coming back Rick?

Richard Castle believes in you and I believe in him.

Beckett

Martha

Esposito [on Castle and Beckett]

You are to close to this one, you need to go home. Now.

Beckett

Shut the front door.

You can't just stay out of my personal life, can you?

Beckett

The only luxury I really care about is freedom.

Detective Beckett, did you call to tell me a bedtime story?

Castle Quotes

I need time to stop being mad and you need time to figure out a way to be OK with this.

Alexis

I tried to stay in the car I really did.
