The NATS meet representatives from various FBI branches to help them decide their future paths. In the future, Alex continues to search for the terrorist, and in the process, discovers some familiar faces – including one who knows the terrorist's endgame.

The NATS are excited that graduation is near as they prepare to leave Quantico and head out into the real world for their new assignments. In the future, Alex learns someone she cared about at Quantico is not who they seemed to be, as she finds herself at the heart of another possible attack.

Shattered by Amanda's programming, her inability to save everyone, and her ultimate responsibility for the tragic events at Division, Alex reverts to old ways and violently strikes out.

As memories of Division's glory days haunt them, Birkhoff struggles with his own personal losses.
