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.

Rick Castle

That's your story, Jerry. Why you did everything. You needed to prove it, so I let you.

Rick Castle

All the games. All the manipulations. After I screwed up your plans you needed to know you were smarter than me. You needed to know you could control me.

Rick Castle

And please don't scream. It's tedious and no one can hear you.

Dr. Kelly Niemann

(to Beckett) Despite the situation I want you to know that I admire you. I always have.

Dr. Kelly Niemann

Ryan: Do you think she's still alive?
Castle: She's alive.
Ryan: How do you know?
Castle: Because he's not done with me yet.

If I took you I'd only get to kill you once but this way I get to kill you over and over again.

Jerry Tyson

When I first got here I couldn't figure out what Beckett saw in you but you know what she said? He sees the story. I see the evidence, where it leads but he sees the story.

Capt. Gates

Castle Quotes

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

Castle

The moment we met my life became extraordinary. You taught me more about myself than I knew there was to learn. You are the joy in my heart. You are the last person I want to see every night before I close my eyes. I love you Katherine Beckett and the mystery of you is the one I want to spend the rest of my life exploring. I promise to love you, to be your friend and your partner in crime and life till death do us part and for the time of our lives.
