Intro: Life is not easy even for a seven hundred year old Time Lord and at times of great stress, which is to say regeneration, he repairs to his sanctum sanctorum, the zero room, a part of the TARDIS which we were never privileged to see before tonight's adventure, "Castrovalva."

Outro: Next week, the TARDIS will intercept a giant, alien spaceship, manned by a [inaudible, possibly "stained"] green race called Urbankans. Their mission is as much a mystery as the title of next week's adventure: "Four or Doomsday." [source: ChicagoEpguides]
