barrier created by Ace's trust in the Doctor stops the Haemovore. Fenric tells Ace she is one of his wolves, having created the time storm that took her to Iceworld to meet the Doctor, and she furthered her own cycle by making sure Audrey, her mother, was safe. Ace's faith in the Doctor is shattered but, instead of attacking, the Ancient One grabs Fenric and takes him into the gas chamber and sets it aflame. The Doctor and Ace flee the base before it explodes, killing Fenric and the Ancient One and ending the Haemovore threat. Ace takes a moment to contemplate why she hates her mother and to celebrate overcoming her irrational fear of the water, before she and the Doctor depart. Continuity The Doctor chants the names of his former companions to ward off the Haemovores. Most of the names he chants are inaudible, but a few can be made out, including Susan, Barbara, Vicki, and Steven, companions of the First Doctor. Ace mentions an old house in Perivale. This was originally intended as a foreshadowing of Ghost Light; the resequencing of the broadcast schedule, however, altered it into an apparent reference to a past story. Similarly, the Doctor's new wardrobe for season 26 was hidden throughout part one by a long duffel coat, setting up a dramatic revelation when he removed the coat. Sylvester McCoy, however, has stated that he was given the coat to shelter from the cold weather on location, and was permitted to retain it on-screen. Production Pre-production Writer Ian Briggs based Dr Judson on Alan Turing. In an interview for the DVD release of this story, Briggs said that since at that time it was not considered appropriate to depict a character's struggle with homosexuality in a family programme, he transformed Turing's frustration at being unable to express his true sexual identity into Judson's frustration at being disabled. In the same interview, Briggs stated that he intended to suggest that both Judson and Millington were gay and had a shared past, although this was not realised in the finished programme. This story was originally going to be titled The Wolves of Fenric (and before that, Wolf-Time). Fenric does refer to his servants as his "wolves" (and wolves play a strong role in Norse mythology, especially the monster Fenrir). However, Nathan-Turner felt that as the "wolves" connection was not revealed until quite late in
