Castle: How do you know when you're in love?
Beckett: All the songs make sense.

Back stabbing, adultery and betrayal. That is why I hate politics.

Kate Beckett

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.

Rick Castle

Esposito

Beckett: Why do you always have to touch everything?
Castle: I thought you liked that about me.

Or our victim was naughty instead of nice.
