One thing is certain: on the evidence of the Matrix, the Doctor is guilty as charged! In Terror of the Vervoids, the Matrix relates how the Doctor and Mel arrive on a space liner just as a series of grisly murders begins. In The Ultimate Foe, the Doctor asserts that the evidence of the Matrix has been tampered with. In a dramatic intervention, the Valeyard's true identity is revealed...
