“Secret's Safe with Me” quotes from Castle

My little girl is going to college.

Martha

Seems like just yesterday you were checking under the bed every night promising her that monsters aren’t real.

I lied. Monsters are real. They’re the boys in her freshman dorm.

Martha

Oh, speaking of which, before Alexis leaves, don’t you think you should have then, um... talk with her.

You mean the sex talk? Mother, I covered that ages ago. I learned so much.

Martha

I mean the you and Beckett sex talk.

Mother, Beckett and I haven’t...

Martha

Save it. Richard. I knew the morning I walked in here and the poor girl was hiding in the closet.

How did you know that?!

Martha

Mothers know these things. But I don’t think you want Alexis to walk in unannounced and find you and Beckett... out of the closet. And by out of the closet...

I know, I know what you mean by out of the closet.

Martha

So, don’t you think you should tell her?

Alexis

Tell me what?

Beckett

Even on the worst days there's a possibility for joy.

Beckett

Yeah, well, the key to Wendy’s murder might be in that junk and we’re about to lose it. There’s no way I can get a warrant in time.

Castle

May not have a warrant, but I got something better. Checkbook.

Auctions are cash only, hotshot.

Castle

Oh, no. What are we gonna do? Is 2 grand enough?

Beckett

What are you doing with 2 grand in your pocket?

Castle

I’m a best-selling author. Why wouldn’t I have 2 grand in my pocket?

Castle

You are so going to owe me for this.

Beckett

Castle, I don’t know if the department’s gonna be able to reimburse you for all of this.

Castle

[Whispering] That’s not the owing I mean.

Esposito

Who knew that Gates had a softer side? It’s, um…

Ryan

Creepy. Very, very creepy

Castle

I’ve worked a lot of murder cases, waiting patiently for the day I could unequivocally exclaim… [Turns around and points to Kirby] “The butler did it!”
