Where have you been all my life?

Keep 'em coming pal, you're doing great.

Guilty pleasure or just guilty?

Don't miss me too much. The dog. Not you.

Do you have a case of puppy love, Esposito?

Castle: We could keep him here at the precinct. We could use a mascot.
Espo: I thought that's what we had you for.

Dog Whisperer? Check. People Whisperer? Not so much.

Castle: Your friends name is Buttons Dutton.
Martha: That is unfortunate.

This is politics. Perception is reality. The truth won't matter.

Give him a chance because the moment you make a move on him, his career is over.

Castle: So we can narrow our suspects down to rich men with good taste.
Beckett: You saying you're a suspect?

That's going to be like looking for a needle in a needlestack.

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.
