At Quantico, an emergency disciplinary hearing causes deep secrets to be spilled, while in the future Alex works covertly with her team to find the real bomber before her time runs out.
The twins, Caleb, Shelby, Natalie and Simon go to work investigating the rest of their class to find the real traitor. Liam frees Miranda and they convince Alex to put the others under surveillance since Alex is now the only NAT who cannot be guilty. Nimah discovers what they're up to and tells the others, while reprimanding Raina for her sympathies towards the terrorist they were dealing with. Simon meets with his bomb maker friend and then reveals to everyone that the Grand Central bombing is based on a dark plan he once devised, but denies knowing anything about the bombing itself. At Quantico, the NATs are assigned to help vet the next class. Alex and Ryan investigate Natalie who is called before the NAT review board under suspicion of lying on her application. Nimah learns the truth of Simon's past and forces him to reveal horrific details to the rest of the class. Ryan defends him, but accidentally reveals that Simon attacked him weeks earlier and Simon is dismissed from training. Natalie is allowed to continue while Ryan and Alex discuss their future before he departs.
