Cory had suspicions when he received reports of Dalek-like ships near Kembel. To carry out his mission, he comandeered a spacecraft and, without revealing his suspicions to his superiors, crash landed on Kembel with crew members Jeff Garvey and Gordon Lowery, who did not know the true purpose of their expedition. There, he was proven correct as Garvey had gotten infected by a Dalek-created Varga plant and made into a homicidal creature. Cory informed Lowery of the mission. Cory was forced to kill him, just as he had already killed Garvey.
