Gibbs, Jen and others in “Probie”

Gibbs

You're still here?

No. I'm the Director's doppelganger!

Gibbs

I never did know what that meant! (to a girl who has rode in the elevator with them) Goodnight!

(scared) Goodnight!

Gibbs

So a doppelganger is someone who's pissed?

Yes Agent Gibbs this one definitely is!

Gibbs

Why?

Why? Because you countermanded me in front of Metro Police!

Gibbs

I didn't countermand you! You overruled me!

Oh...Semantics!

Gibbs

(as she walks out) Is that like "doppelganger"?

(from down the hall) Get a dictionary!
