NCIS, Season 10

Ducky:
Where is Captain Westcott, other than at the forefront of your mind?

Gibbs:
He's headed home. Doc ok-ed me getting into the ambush and I pushed. Pushed too hard.

Ducky:
It's obvious that you feel a grave responsibility towards this young man.

Gibbs:
Ducky, I sent home plenty of Marines like Westcott. 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. 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.
