The agents are in various stages of reading Duckys memoir while the good doctor heads back to New York.

Then the whole system shuts down, locking everyone into place.
Senior, still in Duckys lab coat, identifies himself as Dr. Mallard.
He calls Abby an intern, citing her clothes as evidence (ha!
), and steps in front of her to keep the gunman from shooting her.
Looks like the crew is after some evidence.
You know, as you do.
1 arrives with Ducky in tow.
He spots Torres framed desk photo of himself (excellentcallback see what vanity gets ya, Nicky?)

2 works for Fincher and is addicted to pills.

In MTAC, McGee listens to the order and realizes theres another conspirator involved.
The call is coming from inside the house!

Torres humblebrags that hes never been dumped.
Senior asks, and Torres says theyre not an item, but asks eagerly, Did you hear something?

In the orange room, Gibbs has rigged the office equipment to start making noises, distracting gunman No.

Wright finally gives him the go-ahead, and he and an armed team storm in.
Vance does, and with Gibbs gun, no less.
As she regularly sleeps in a coffin, she managed to nap through the whole ordeal.
Then another explosion rattles the building.
NOT COOL, Bishop.
(Palmer, I know you were just along for the ride.)
To celebrate, Senior offers to take everybody out for drinks, although nobody can find Gibbs.
Seriously, was there ever any doubt whose rooftop hideaway that was?
