Castle, Martha and others in “Secret's Safe with Me”

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?
