Dinner lady (School Reunion)

This Dinner Lady was a Krillitane who had taken human form and worked at Deffry Vale High School as a dinner lady. She fed the children chips cooked in Krillitane oil so they would become smart enough to solve the Skasis Paradigm. She was killed when K9 heated up the drums of Krillitane oil in the kitchen and blew up Mrs Jackson, the other Krillitanes, the school and himself. (TV: School Reunion)
