    • Castle: Even your coffee mugs say CIA. That is so cool.
      Sophia: Well, we save the world, maybe I'll let you keep one.
      Castle: Incentive.

    • Sophia: You always did like playing with dynamite. Just be careful it doesn't blow up in your face.
      Castle: Beckett's different.
      Sophia: Is she? Or do you just think she is?

    • Beckett: I thought you were off the case.
      Castle: Well, you heard what Sophia said. I'm a reckless, immature, self-centered jackass. If you're stubborn enough to keep going, I'm stupid enough to go with you.

    • Esposito: Fake deaths, car in the water, don't you think now is a good time to tell us what the hell is going on?
      Castle: Uhm...
      Beckett: I'm sorry, Javi. It's classified.
      Esposito: I was Special Forces. I used to eat classified for breakfast.

    • Castle: So what's our next move?
      Sophia: There is no next move. Not for you two. It was a mistake bringing you into the loop. You know, I really thought, I really thought you had changed. But you know what? You are the same reckless, immature, self-centered jackass that you always were, and you've put this investigation at risk.
      Castle: Look, I'm sorry...
      Sophia: You're sorry? We are on the verge of the next 9/11 or worse. This isn't one of your damn books, Rick. This is real life, and when things go bad, you can't just rewrite the ending like you did with us.
