When Davros is revived and asked by the head of an Earth corporation to use his great genius to work for good ends, the Kaled scientist seems to be playing along. The Sixth Doctor arrives and insists that Davros cannot be trusted, that he is "one of – no, actually, the most evil being this galaxy has ever produced!" Forced however to work alongside his nemesis, on projects such as famine relief, the Doctor seeks to uncover Davros before he can put new schemes to create a powerbase into effect.
