Jon Pertwee Third Doctor Doctor Who science-fiction television programme produced by the BBC. The adventures of the Doctor, a Time Lord. Exploring the universe in his TARDIS, a sentient time-travelling space ship appearing as a blue British police box.
Journey's End is worse than Doomsday. Not even because he's lost Rose again, but because he got everyone back, everyone he cared about, everyone who helped him survive, and lost them all. It's no wonder regeneration wasn't long in coming after this.
