With their energy levels running low, the Cybermen return to their tombs whilst the Cyber-Controller and a partially converted Toberman meet with the group. Taking him to the revitalizing chamber, the Doctor attempts to sabotage the process, only for the Controller to escape and turn on the group. After it murders Kaftan, Toberman breaks free of the Cybermen's conditioning and apparently disables it. Whilst he, the Doctor and Jamie return to once again freeze the tombs, Klieg, unable to accept the Cybermen will not forge his alliance, tries to stop them, only to be murdered by a remaining Cyberman. After Toberman destroys it, the Doctor activates the tombs, hoping that the Cybermen will stay there for good.
