NCIS, Season 7

Ziva:
A team of Homeland Security officers will be waiting for us when we land. Outside the terminal an NCIS detail will take over.

Marshall Neeley:
Not taking any chances in case your new hitman tries something on the ground, huh?

Ziva:
Which is why we must consider the possibility they may try something on the plane, where Nora is more vulnerable.

Neeley:
You have reason to believe they're on board?

Ziva:
Stationary target. Closed quarters.

Neeley:
A modern day Orient Express.

Ziva:

Ziva:
Headphone cables make for a perfect garrote, and plastic silverware is not as safe as you might think. I once killed a man using a credit card.
