According to Chuck, ears are just as identifiable as fingerprints.

I was dubious, but Google tells me this may be true.

Anyway, they track down Lloyds ear and have a go at follow him around D.C.

They do some Lloyd research and realize that Lloyd has an estranged son nearby.

Even though they havent spoken in 10 years, the FBI decide to bring in said son, Travis.

Meanwhile, the president meets with two senators and their lawyer to apprise them of the Lloyd-back-in-the-U.S. situation.

Since he promised transparency, Kirkman wants to reveal to the public that hes returned.

Emily and Aaron think thats a terrible idea, as it will create panic, and even Lyor agrees.

So they decide to inform the House Senate Committee.

Two senators come with their lawyer to talk with Kirkman, who lets them know the situation.

The Missouri senator is not pleased.

Hes from the Show-Me State, after all.

When Kirkman finds out,heis not pleased.

He calls him back in and verbally lashes the guy: I dont play ball.

Hannah and Damian head there immediately and find a car parked on the empty lot.

But just as soon as they start exploring, Lloyd starts firing on them.

Damian is grazed by a bullet, but Hannah is able to chase Lloyd down.

Shes about to catch him when he seals himself inside a metal bunker.

Chuck is able to cut off the bunkers T1 line Lloyds internet.

They use a firewall to confirm any communication with the outside world goes directly to them instead.

But Lloyd only sends one message…one straight to the president.

Emily says that military action against a civilian target is unprecedented and could be unlawful.

That doesnt work, though.

Hannah and Damian venture to breach the compound from a complex tunnel, and that doesnt work either.

So they end up dropping the drone bombs on the compound and neutralizing the threat.

The find Lloyds remains (SURE THEY DID), but no sarin gas.

Kirkman addresses the U.S. public, giving a rousing,West Wing-style speech.

And they dont know what it is.
