Malcolm Wainwright

Malcolm Wainwright is grandson of Kathy and Ben Wainwright. In the episode Blink he delivers a letter from his dead grandmother, Kathy, who a second ago had been by Sally Sparrow. His great-uncle is Larry Nightgale, who was Kathy's brother. At the end of Blink, Sally walks off with Larry, which could suggest that one day Sally will be related to Malcolm.
