It's midterm exam time at Quantico where the NATS are given an explosive assignment which results in some people going home for good. In the future, Alex continues to try and clear her name, finding Nimah and Raina who provide more questions than answers leaving Alex and the world to wonder, "who can you really trust?"

At "Quantico," the NATS attend a class with guest speaker Dr. Susan Langdon. Dr. Langdon is a former agent and profiler who tasks the trainees with looking at serial killer cases to find the one victim that doesn't fit the case, but when Simon becomes too good at finding things that don't belong, it's his life that becomes endangered. In the future, Alex is interrogated by a highly sophisticated FBI team while Ryan's life hangs in the balance.
