Doggett finds a strange disfigured man in the X-Files office; believing he is Mulder, Scully has his DNA tested, and the results reveal him to have the same pattern as Mulder. The disfigured man sticks a needle into William, which the other agents believe to be a virus of some kind, but it is later revealed to be a cure for William's powers. The unnamed man is later revealed to be Jeffrey Spender (Chris Owens), Mulder's half-brother. In the season finale, Mulder returns from hiding in the attempts of finding classified information at an army base. He is caught, however, after allegedly killing an apparently indestructible "Super Soldier", which causes him to be tried before a military tribunal. With the help of Kersh, Scully, Reyes, Doggett, Spender, Marita Covarrubias (Laurie Holden) and Gibson Praise (Jeff Gulka), Mulder breaks out, and Mulder and Scully travel to New Mexico to find an old "wise man", later revealed to be the "Cigarette Smoking Man" (William B. Davis). He tells the two that aliens will begin colonizing the planet on December 22, 2012. Cigarette Smoking Man appears to be killed by a missile, launched under the command of Knowle Rohrer (Adam Baldwin), who is revealed to be alive and well. Mulder and Scully escape, but become fugitives on the run from the FBI. The final scene of the season features the two in a motel room facing an uncertain—but possibly hopeful—future.
