The moment that I met you, my life became extraordinary. You taught me to be my best self, to look forward to tomorrow's adventures. And when I was vulnerable, you were strong. I love you, Richard Castle. And I want to live my life in the warmth of your smile and the strength of your embrace. I promise you I will love you. I will be your friend and your partner in crime and in life, always. - 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're the last person I want to see every night when 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. - Richard Castle
