Kubrick was right. A. I. is a bad idea.

Rick Castle

I wanted to go to Mars not die on Mars.

Rick Castle

Space. The final frontier. These are the voyages of Castle and Beckett. They're ongoing mission to explore strange, new motives. To seek out new witnesses, new suspects for murder. To boldly go, oh, right over here.

Rick Castle

Rick Castle: Checking you for bites and scratches. Just making sure you didn’t somehow get impregnated.
Kate Beckett: If you think that’s how I’d get pregnant we need to talk.

Mars. Nova Scotia. This guy really loves barren landscapes.

Kevin Ryan

One small murder for man, one giant mystery for mankind.

Rick Castle

Kate Beckett: Wait, you signed up to go to Mars. When?
Rick Castle: A couple years ago.
Kate Beckett: Where was I?
Rick Castle: We were fighting.

Kate Beckett: Four adults together in one space, we're bound to step on each other's toes.
Rick Castle: Yeah, well there were a lot more toes than usual tonight.

Castle we have a murder. To solve not to commit.

Kate Beckett

Kate Beckett: Thanks for coming to get me.
Rick Castle: Always.

Rick Castle: I don't know how you did it.
Kate Beckett: What?
Rick Castle: Kept it together the two months I was missing. Two days I didn't know where you were and it nearly killed me.

The truth is I lured you here to watch you die.

Castle Quotes

Beckett: (Clears throat) Ahem. What's the deal with men and boobs, anyway?
Castle: Biological. We can't help it.
Beckett: But doesn't it bother you that they're so obviously not real?
Castle: (Pauses) Santa's not real. We still love opening his presents.

Sometimes the hardest things in life are the things most worth doing.
