Now they are both trapped in Paris. The ants have followed them and Kadiatu takes the Doctor to M. Thierry's house for shelter. Despite his confused state of mind, the Doctor still realises that Thierry's young son is not all he seems and suspects Thierry is really in league with the ants. Thierry and Kadiatu have been helping the Doctor recover, playing for time and hoping that he will reveal to them the information that Ship couldn't take from his mind. Ace has the TARDIS buried in the monument at Amarna and writes a message on the wall, so the Doctor or Bernice will eventually find it. She then uses Sesehaten to open the rift and with the help of the force shield, escapes through it. In 1798, Bernice does indeed find the TARDIS and after saying goodbye to Denon, she too leaves for the Doctor's location. In Paris, Thierry uses the ants' technology with Kadiatu's time machine to stabilise the rift, but unfortunately the Doctor has filled it with explosives, hoping the ants would take it back to Ship. The resulting explosion kills Thierry and tears the rift completely open. A little boy appears and attempts to stabilise the rift as first Ace, then the TARDIS come through. He is a machine built to stabilise the rift like Sesehaten. As the rift widens, Ace shoots the boy, sealing the rift in the process. The Doctor, his mind recovering, explains to Ace and Benny that Ship is an organic computer, built by a human colony to store their minds in a gestalt entity, but having fallen through Kadiatu's rifts, it is now trying to store all organic matter in the universe and has built the ship and the ants to fulfil its purpose. The travellers return to Paris and Ace watches the chaos around her. Knowing that the Commune will fail and thousands will be killed, she tries to persuade the woman fighters that their attack are pointless, just as Akhenaten's religious reforms were ultimately undone and forgotten. But the fighters believe that fighting for their beliefs is more important than winning. Bernice finds Kadiatu is giving Ship dead bodies killed in the Commune to process into organic machinery for time travel. Ship has also infected Kadiatu with an organic virus that is slowly taking her over. She has been playing for time hoping to come up with a virus
