NCIS: Los Angeles2009

Nate Getz:
Hey, listen to this. "In flaming fire taking vengeance on them that know not God."

Special Agent Kensi Blye:
Sounds like the Koran quote Olin put on his car.

Nate Getz:
It's essentially the same, only this is from Thessalonians.

[realization dawns on Nate]

Nate Getz:
Oh, boy.

Special Agent Kensi Blye:

Nate Getz:
The bible was a gift from Olin.

[Kensi shrugs her confusion]

Nate Getz:
