Season 1   Season 3

Tick, Tick, Tick… is the seventeenth episode of the second season of Castle.


Beckett and Castle team up with experienced FBI Special Agent Jordan Shaw in the hunt for a serial killer with an apparent "thing" for Nikki Heat, the character Castle based on Beckett in his best-seller Heat Wave. It soon becomes clear that not only is Beckett jealous of Castle's admiration for Shaw and the FBI's hi-tech gadgets, but that Beckett herself could be the killer's ultimate intended victim. Castle also strikes a deal to make Heat Wave into a movie.

Castle: Oh, no. I’m not leaving. I’m here to protect you.
Beckett: What, with your vast arsenal of rapier wit?
Ryan: Dude, you made her pancakes?
Castle: It’s just breakfast.
Esposito: Pancakes is not just breakfast. It’s an edible way of saying, “Thank you so much for last night.”
Castle: I never intended to put her in harms way.
Martha: Let me tell you something about Detective Beckett. That gal can take care of herself. Really.
Castle: (On phone) It wasn't Ben Conrad. He's not the killer. The killer's still alive! THE KILLER'S STILL ALIVE!!
The Killer (over Beckett's phone in the background): Goodbye, Nikki. Goodbye, Nikki.
Castle: Kate!?
