Beckett: How am I supposed to get my bearings when someone out there wants me dead?
Castle: By not letting them rob you of your life. I promise you, we will figure this out. We're gonna find them and we're gonna make them pay. Just not today.
Beckett: Castle, if I don't do this, I don't know who I am.
Castle: You're who you always were. You're the one who honors the victims.
