Zagreus (audio Drama) - Plot

Plot

Zagreus sits inside your head, Zagreus lives among the dead, Zagreus sees you in your bed and eats you when you're sleeping...

- old Gallifreyan nursery rhyme.

Following directly from the events of Neverland, the casket of anti-time which was destined for Gallifrey had exploded within the confines of the TARDIS. It seems that the Eighth Doctor and Charley have saved Gallifrey, and that the paradox of Charley's existence had been resolved, but the Doctor begins behaving strangely — he has been taken over by Zagreus.

The Doctor/Zagreus rages through the TARDIS and strikes Charley, but there is a loud explosion, and when they recover the Doctor/Zagreus is alone in the TARDIS. Charley finds herself in Harley Street talking to her mother Lady Louisa Pollard, who mentions amongst other out of place information that one of her sisters is called Romana. Charley is taken to see a Dr Zagreus, and her mother turns into a white rabbit from Alice's Adventures in Wonderland. Charley then meets someone whom she recognises as the Brigadier.

The Doctor/Zagreus, unsure of his true identity, stumbles into a TARDIS library. He hears a mysterious voice in the TARDIS, that of one his previous incarnations, the Third Doctor. The Brigadier tells Charley that everything she has seen is a holographic projection created by the TARDIS. She is then shown scenes from her own memory to provide her with insight into what has happened to the Doctor.

The Doctor leaves the library through a secret passage and finds a part of the TARDIS unaffected by the anti-time infection, from where he is able to converse with Zagreus. Zagreus shows him all possible alternate time lines, including universes where the Doctor plucked out one of his own hearts1, and tells the Doctor that he would destroy all of them if he was unleashed.

Charley and the Brigadier find themselves in another holographic projection, this time a 1950s army barracks. Charley realises that the Brigadier is also a hologram, created by the TARDIS. The Brigadier mentions something called "The Divergence" and says that the Time Lords would not be able to intervene lest they become infected with the anti-time. In the TARDIS, the Doctor hears the Third Doctor's voice again and finds a book The Alice Compendium in which he reads Charley's name and the phrases "the divergence" and "Nana Saviltride".

Charley and the Brigadier realise the projection is of Cardington, where the R101 was launched in 1930. There, a Doctor Stone is conducting an experiment, which causes a huge explosion. The Doctor hears the explosion and rushes to the TARDIS control room, but finds himself instead in a forest. There he encounters a talking Cat and a large metal box. The Cat tricks the Doctor into entering the box, which is a Schrödinger's cat demonstration. The Doctor realises the meaning — if he left the TARDIS he would become either fully himself or fully Zagreus.

At Cardington, Stone argues with the base chaplain Matthew Townsend about his research. Townsend expresses reservations about possible military applications of Stone's research, and wonders about the course of human evolution. Charley overhears Stone talking about the military application of "Dionysus"2 — the code name of her project. It had torn a hole in reality, which might be used as a weapon. Miss Foster, who had told Charley and the Brigadier that she was a military secret agent, tries to plant a bomb on the Dionysus project; she was in fact a spy for communist Cuba. Threatening to kill them all, Foster forces Townsend to operate the machine, creating another rift in time. All but Charley and Townsend are sucked into the rift; on the other side of the rift are creatures trying to break through.
