So much ado by the Valeyard and the Master over the Doctor's death makes the Doctor wary of being made decoy for some other, truer target. Continuing in the Matrix itself, he may find both them and the answers he seeks.

Production on this episode was notoriously troubled. 'Robert Holmes' (II) was originally commissioned to write the two episodes. However, he died from a chronic liver ailment after completing a draft of the first and left nothing beyond a plot outline of the second. The series script editor Eric Saward
resigned around this time due to disagreements with the producer, John Nathan-Turner
, but agreed to write the final episode based on Holmes' outline, and also rewrite Holmes' draft to tie the two together, for which he was credited as Script Editor. The original ending to this segment (and, indeed, the whole Trial story and possibly the series) would have seen the Doctor and the Valeyard in an inconclusive cliffhanger, both (seemingly) plunging into a void to their deaths as an extra "hook". However, Nathan-Turner felt this was too downbeat and believed that it was important that the season did not end on an inconclusive note since it was important after the hiatus to prove the series was back in business. Saward refused to change the ending and withdrew permission to use his script very late in the day, by which point the production team had been assembled and the segment was entering rehearsals. Nathan-Turner commissioned Pip and Jane Baker to write a replacement final episode. For copyright reasons they could not be told anything of the content of Saward's script (and there were lawyers observing all commissioning meetings). See more
