NCIS, Season 6

Eli David:
You know, Leon, sometimes, those who know me ask me directly -- the brave among them -- but most of the time the others, I can feel them looking at me and silently wondering, how can a father possibly raise his daughter to be a professional killer?

Vance:
A question that I've never asked you because I know the answer.

Eli David:
Every day is a fight to survive. It is my dream that my daughter will not have to make that decision with her sons and her daughters; I would like my grandchildren to be doctors and architects, to live a happy life, to grow fat and old. [pause] You want her back, don't you.

Vance:
Yes, Eli, I want her back.

Eli David:
Tell me, Leon, are we winning?

Vance:
I don't know, Eli.

Eli David:
I like to think we are... and then there's something else: a bombing, a kidnapping, an atrocity. Use her well, Leon. Ziva is the sharp end of the spear.

Vance:
Thank you, Eli.
