NCIS Season 12 Episode 2 Quotes

Vance: Surgeon didn't pull any punches. He asked me if I had my life in order.
Ducky: And do you?
Vance: No. Since Jackie's death I haven't been able to focus. I haven't redone my will, nor have I made any provision for the care of my children.

Francis: Can I ask you a question, Bishop?
Bishop: Sure.
Francis: You enjoy working for Gibbs? I mean I heard he's tough. A real hard-ass. He's standing right behind me, isn't he?
Bishop: Yeah.
