In the second episode of the four-part story "Terminus," the efforts by Turlough (Mark Strickson) to destroy the TARDIS forces the vessel to lock itself into the flight pattern of an alien space station. To the Doctor (Peter Davison), this is danger enough, but things are far worse than they seem; the space station is populated by victims of the highly contagious Lazar's Disease. First telecast on February 16, 1983, "Terminus, Episode 2" was written by Stephen Gallagher. ~ Hal Erickson, Rovi
