Intro: "You can't go home again" wrote Thomas Wolfe, and perhaps The Doctor should have heeded that advice. What Wolfe meant, of course, was "Things ain't what they used to be." And The Doctor, on his way to Gallifrey, will ruefully learn that truth. "The Deadly Assassin" is next.

Outro: Leela is a lovely looking bird. Trouble is, she carries a crossbow and a knife and is inclined to stab first and ask questions later. The Doctor befriends this attractive savage next week when he confronts "The Face of Evil." [source: ChicagoEpguides]
