NCIS: Los Angeles, Season 2

[Sam is opening a box]

Hetty:
What are you doing?

Sam:
I need to activate a former alias.

Hetty:
Oh, no. NLV. NLV. "No longer viable. " Tyrell Ellis was compromised.

Sam:
I know. I was Tyrell Ellis, remember?

Hetty:
I also remember you were nearly killed before we got you out.

Sam:
My cover was never blown. I spent 7 months undercover working Memo Torres when he was still a cartel underling. Now he's the man. That means he's the fastest route to find those missing Marines. And the only person who can get to Torres right now, is in this box.

Hetty:
The man in this box has a price on his head. Why don't you just arrest Torres?

Sam:
We don't have anything on him. We yank him in off the streets and we blow any chance of ever going back under in his organization. Plus, Memo hates cops of any kind. He'll be lawyered up as soon as we bring him in and we may never find those missing Marines, Hetty.

Hetty:
[Callen walks in] Oh, Mr. Callen, could you please talk some sense to your partner?

Callen:
What, like that's ever worked? Admittedly, putting Sam on the streets as Tyrell Ellis is not without risks. Memo Torres is behind this. Reactivating Tyrell Ellis is the only way to find him.

Sam:
It's our only bet, Hetty, and you know it.

Hetty:
I don't like it.
