The Trial of a Time Lord: Part Thirteen 

The charge against the Doctor changes from mere meddling to inexcusable genocide. His future looks both grim and very short.

With the evidence for the defense at an end and the trial nearly over, it would seem that the Doctor's fate has been well and truly sealed. But the shock intervention of an old adversary throws new light on the case with the Doctor's future traveling companion Mel and the roguish Sabalom Glitz being presented to the courtroom as surprise witnesses. Shocking revelations come to light involving the high council of Time Lords, the Valeyard and their corrupt conspiracy which involved the Doctor and his affairs with the planet Ravolox. But with an even more mind blowing revelation brought to the fore, the Doctor is forced to come to terms with an enigmatic link between himself and his sinister prosecutor.

Two deadly foes.
28 December 2019 | by Sleepin_DragonSee all my reviews

Facing a charge of genocide, The Doctor stands accused, but a deadly foe explains the true sequence of events.

I loved it, this really did feel like a game changer, the appearance of The Master comes as a big surprise, but it's more true identity of The Valeyard, and the possibilities there surrounding. At the time the concept of a Doctor so far in the future must have felt a lifetime away, whereas now it's a reality.

I know it's right at the end for him, but I've always considered this to be Colin's definitive performance, he is outstanding here, and his speech in the court, his finest moment.

The stuff surrounding The Matrix and The Sleepers was excellent, great storytelling.

Loved it. 9/10
