It was never like it is with you and me.

Do you realize what this means? We're like spies. it's like a Jason Bourne movie.

Gives new meaning to the term overkill.

Beckett: Did you just say Kate? Are you picturing you as the PI and me as the gangster's girlfriend?
Castle: No!

That's the stuff dreams are made of.

I got no love for this thing, just you.

Why am I narrating?

She was worth every punch.

If I'm anything, I'm discrete.

Where have you been all my life?

Guilty pleasure or just guilty?

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.
