The Human Enigma[]

Mason boards a train in the Italian Alps, on a mission with Citadel. He finds his colleague, Nadia, who seems surprised to see him- insisting she can handle this mission alone. Mason covers Nadia as she locates and moves in on her target. He fights some of the target's men and beats them. Mason enters the dining car and sees Nadia in trouble. He starts shooting, but the target detonates a bomb and Mason goes flying out of the railcar.

Mason wakes up in a hospital bed in Bellagio, Italy. A doctor tells him he's suffering from retrograde amnesia. He tells him his name is Kyle Conroy and passes him his passport and wedding ring, informing him there is no record of him in the U.S.

His former colleague Bernard points a gun at him and his family, instructing them to get in the car. Mason has no idea what's going on because he doesn’t recognize Bernard. Back at Bernard's, he explains to Mason his real identity and his former profession- as a Citadel agent. He asks Mason to help him with an urgent Citadel mission- in exchange, he'll tell Mason who he was before the train crash.
