The Two Doctors

TV Season 22, Serial 4

Aired: 16 February - 2 March 1985

The last multi-Doctor story in the classic series, and Patrick Troughton’s last appearance on the show. Unfortunately, it messes up continuity something fierce, because the Second Doctor is clearly older and working for the Time Lords, along with Jamie, which could mean it’s meant to be set after “The War Games,” or if you prefer, it takes place in the middle of “The Black Hole.” See the Season 6B theory for more info.
