The Ultimate Foe (TV story)

Synopsis
The final episode in the season-long 'Trial of a Time Lord' saga, a surprise appearance of the Master reveals the treachery of the High Council of Time Lords, and that the Valeyard is not what he appears to be.

Story Notes

 * Mel leaves with the Doctor at the end of this story, despite being from the Doctor's future. This is extremely odd, since it dramatically increases the probability that this "older" Mel will encounter her younger self at some point, and fall victim to the Blinovitch Limitation Effect.  This possibility was neatly sidestepped by the following story, Time and the Rani.  Since it immediately depicts the regeneration of the Sixth Doctor, there is presumably a wide gap between it and Foe.  The arrival of the Seventh Doctor instantly mooted any televised treatment of the asynchronicity between the Sixth Doctor and Mel.  Nevertheless, the issue has been addressed in other media.  In MA: Time of Your Life, writer Steve Lyons posited that the younger Sixth Doctor immediately took Mel back to his older self.  The issue of the Doctor's knowledge of Mel prior to their first meeting is examined in PDA: Business Unusual''.
 * What the Master said about the Valeyard giving him the remainder of his regenerations to him contradicts the Master's explanation of his regeneration in The Sound of Drums and mostly The Five Doctors.
