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.

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.
