Season Twenty-Three a (the original)

The original Season Twenty-Three was cancelled. Three of the scripts were later published, and form the basis of Season Twenty-Three a.

Season Twenty-Three - The Trial of a Time Lord

Code	Title	Type	Rating	Notes
7A	The Mysterious Planet	(4 episodes)	5
7B	Mindwarp	(4 episodes)	5	Peri leaves.
7A-C	The Trial of a Time Lord - Trial Scenes	14 episodes	5	The trial scenes immediately follow Mindwarp. Mel appears.
ED1	The Eight Doctors (Chapters 17-21)	Guest Appearance	4	This happens between scenes of The Trial of a Time Lord part 13. Technically, this doesn't feature the Sixth Doctor. The Sixth Doctor we see is an alternate Doctor from a timeline where the Valeyard tried to execute him.

Season Twenty-Three b

There are a number of stories set between the trial scenes of Trial of a Time Lord and the Doctor's regeneration in the next season. I have chosen to group these as a separate season, even though one of the later ones (Terror of the Vervoids) was shown as part of the trial season.

MA8	Time of Your Life	Virgin Novel	5	This happens immediately after the trial. Grant joins.
MA23	Killing Ground	Virgin Novel	5	This happens immediately after Time of Your Life.
