The rebel guerrillas attack the Controller's base and rescue the Doctor, though Boaz is killed. The rebels take the Doctor back to their hideout and tell him the rest of the story: Styles organised the peace conference, and when Auderly House was blown up, everyone was killed. The rebels believe that Styles engineered the whole thing and caused the century of war that followed. Their plan was to kill Styles before he could destroy the peace conference, thus stopping the century of war and subsequent dalek invasion. The Doctor is sceptical, believing Styles to be stubborn, but a good man. When the Doctor finds out that the rebels had brought a bomb made of dalekanium with them, a powerful but unstable explosive that will even affect Dalek body casings, he realises that the rebels are caught in a predestination paradox. They will cause the very explosion that they went back in time to prevent in the first place, and thus create their own history and timeline. Indeed, back in the 20th century, Shura has found his way into Auderly House and plants the dalekanium bomb in the cellar.
