Castle, Season 5

Stack:
So what do you want to know?

Beckett:
Why don't we start with who are you?

Stack:
Jared Stack. Special Investigator for the Attorney General's office.

Castle:
I've never heard of it.

Stack:
[whispering] You're not supposed to.

Beckett:
And what's your connection to Dale Tanner?

Stack:
Tanner was under scrutiny by the FBI, DHS and the Pentagon, not to mention the NYPD Counter-Terrorism Unit. Somebody objective needed to look into his death, so they picked me.

Beckett:
When did you realize that he was killed by a drone and not a car bomb?

Stack:
Once our people examined the wreckage.

Castle:
Why the fake ID?

Stack:
I didn't know where this was headed. The AG needs deniability.

Castle:
"The secretary will disavow all knowledge of your actions." It's Mission: Impossible.

Stack:
Pretty much. I'm even wearing a mask.

Castle:
Really?

Stack:
[whispering] No.
