Owen and Clay are in the midst of a power war.
A small community in Virginia has been evacuated over an explosion at a nearby plant.
All the nearby water supplies have to be checked for contamination before any of them can return.

So Shelby, while finding really good info, does something really weird.
The only person missing from the brainstorm is Nimah.
Hearing she was a mascot and not a real member of the team understandably has her upset.
Shelby wont let her wallow, though.
She tells her to make herself irreplaceable so Clay is forced to respect her.
With enough evidence, Clay says that the group can pay a visit to the trolls.
There are ongoing FBI and CIA investigations into this group and they cant compromise any active missions.
The only people left behind on the mission are Ryan and Nimah.
When he arrives, its Sasha, our inquisitive reporter.
After a brief gun-threat, he admits that the chemical spill isnt real.
Still holed up in her room, Nimah finds a break in the case.
She calls Clay to share her discovery, but Clay screens the call.
(Hes busy continuing his power struggle with Owen, and also, he doesnt care for Nimah.)
Desperate, she actually goes and finds the van and breaks into it.
Greypool isnt looking for a thing; theyre looking for a person.
Now, the Senator is trying to eliminate anyone who knows the truth behind the matter.
Harry and Dayana create a diversion upstairs so Alex and Ryan can slip Mallory out, unnoticed.
She recognizes him immediately.
Clay and Nimah are still uneasy with each other.
There is also the matter of letting Baynard off the hook (for now!)
Clay and Owen meet separately to figure out their next moves.
Then they head off for Mallory.
Meanwhile, Alex sets off to find Harry.
She wants him to join the team permanently and stop trying to get back in Her Majestys good graces.
Hes on the team!
He asks her to dinner, and she agrees.
Also, Clay and Shelby have an oddly flirtatious conversation.
She says in her voicemail that she wants to catch up, but Leon cant answer ever.
