(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!

That was awesome! Beckett never drives on the sidewalk!

Forget severed heads, I want to meet that guy!

Martha: Playing with dolls, are we?
Castle: They are action figures.
