Doctor unmasks Popplewick as Valeyard

As the Doctor and Mel assess growing threats within the ship's deceptive engine room, Popplewick's over-the-top mannerisms arouse suspicion. The Doctor seizes an opportunity to confront him directly, using improvised bindings to restrain his suspected enemy. When Mel joins in the effort, the Doctor strips away the Victorian servant disguise to reveal the Valeyard's true identity beneath. The confrontation escalates as they uncover the Valeyard's weapon—a particle disseminator capable of annihilating all matter at a subatomic level. Realizing the peril to the Time Lords in the trial room, the Doctor forces Mel to leave and deliver a warning before the weapon can activate itself to devastating effect.
