Dinner lady (School Reunion)

Mrs Jackson 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 were smart enough to solve the Skasas Paradigm. She was killed when K-9 heated up the drums of Krillitane oil in the kitchen and blew up Mrs Jackson, the other Krillitane, the school and himself. (DW: School Reunion)
