Or it actually IS Simon and the obvious red herring is just to throw us?
Nimah did mention that the building services people helped keep the Twin Twist secret.
Before I go down a suspect hole I cant crawl out of, lets recap Guilty.
Shes famous for writing a book about the welfare mom serial killer she caught.
To help forget their feelings, shes taking them out for drinks.
Well, that was easy an easy lesson!
At the bar, the NATs are taking shots and playing the serial killer drinking game.
(FBI agents must be a real hoot to hang out with.)
Simon cant let go that one of the victims in his file didnt seem quite right.
He tells her what he really thinks happened to victim No.
He must have struck a nerve because next thing you know shes threatening his life.
She forcefully leads him out of the bar, but luckily Ryan sees it and follows.
Dr. Langdon kisses Simon and whispers, Youll never prove it, before fleeing.
Nimah and Nat yell at Simon when he says he was the informant.
He wanted to hold the bureau to a higher standard, but they see it as a betrayal.
Somehow this leads him to call his bomb-maker friend and plan a meeting.
At their covert meeting, he hands Simon blueprints for the train stations.
Oohhh, looks like we have a new Suspect No.
I think thats code for, We want her to talk freely and tell us where the bomb is.
Hes there as Alexs legal counsel.
They lead her to a room where theyve strung up Ryan, who clearly never made it to safety.
Ryan screams and screams, but Alex has nothing to tell Wells.
Meanwhile, Caleb has been investigating the email his father received about SA Diane Goodwin.
And even more suspicious: Her phone is missing but not her badge, keys, or gun.
Before the FBI was only looking at her movements at Grand Central, nothing before.
Caleb and Elias review the footage of Alex leaving her apartment and find a blind spot where she disappears.
(The biggest mystery of this episode was why it wasnt named Blind Spot.)
In the Hyatt room, they found a very large, empty duffel bag.
He then has a much-needed real talk with Alex.
He tells her hes sorry it took him so long to believe she could be telling the truth.
