WTTW split the story into two parts, with the break occuring during episode two as the Doctor identifies he needs to go to Seville and prepares the TARDIS for "transference". [source: ChicagoEpguides]

Intro: If The Doctor's former self dies, how does that affect his present self? And how can he avoid it? Did Captain Kirk ever have a problem like this? The answers to the first two questions are forthcoming in the conclusion of "The Two Doctors," next.

Outro: One can't be too careful on Karfel, the planet where The Doctor and Peri will find themselves unwilling guests next week. The Doctor had been there in a previous regeneration but there have been some changes made, and they promise to make things interesting, if not to say, dicey. Be with us next Sunday at 11 for "Timelash." [source: ChicagoEpguides]
