Gibbs: Ducky, I sent home plenty of marines like Westcott, and-and I knew their heads weren't right. I hoped that there would be someone on the other side to catch them.
Ducky: You had no choice. I mean, you had to stay behind. It was your duty.
Gibbs: I'm on the other side now. I tried to catch Westcott. I didn't. He wouldn't let me.
Ducky: And when do you take "no" for an answer?
Gibbs: I'm angry, Ducky.
Ducky: You can't fix the world, Jethro. But you can call the boy.
