Four years, I've been right here. For years. Waiting for you to open your eyes and see that I'm right here!

Beckett: How the hell could you do this?

Castle: You're not alone in this. I'm here.
Beckett: I know.

The most worthwhile things in life are often the most difficult. For example
(Phone rings, Beckett calling)

Castle: When a life altering moment occurs, people remember.
Beckett: Maybe it's too big to deal with, maybe he can't face it yet.

Beckett: He's a human killer with a human motive.
Castle: He's a zombie killer with a zombie motive. Eating brains.

My friends, that is a zombie. The killer is a zombie!

Castle Quotes

I don't get it. He's into you and your determined not to give into these feelings that you clearly have for him. So he fantasizes about you through his writing. It is literally verbal masturbation.

Natalie

I can't tell you how many times I've had dreams of being on this very ship.
