 was the husband of Peggy Marsden. He also had a son before a nuclear war. He told Hex about the war. He was trying to build a fallout shelter. After the heat wave from the explosion he went to check the damage. He died of radiation sickness. When time rewound he was alive again. He had been in the timeloop for 100 years and for the rest of eternity. He was placed in the loop by the Seventh Doctor. The two times the TARDIS arrived he noted the colour of the external shell, black when the Doctor arrived and white when Ace and Hex arrived. He waited for Moloch, as his saviour. To escape he wanted to leave Hex and Ace in his place. (AUDIO: Protect and Survive)
