Intro: As sometimes happens, the regeneration has not gone well and The Doctor decides to retreat to the planet of Titan 3 until he can work things out. Unfortunately "The Twin Dilemma" will follow him there.

Outro: Next week, The Doctor and Peri investigate an intergalactic distress call and meet an old nemesis. Be with us next Sunday night at 11 and witness the "Attack of the Cybermen." [source: ChicagoEpguides]
