Recap / The Sarah Jane Adventures S1 E1-E2 "Revenge of the Slitheen"

"The day I was born, I saved the world. Now I've helped to destroy it."
Luke Smith

Luke and Maria start their first day at their new school, but not everything is as it seems, the cafeteria food is mouldy, the air smells like batteries, people are spontaneously getting ill and worst of all, the portly head teacher has gas problems. Aided by their new friend, Clyde Langer, Sarah Jane and the gang discover a sinister revenge plot engineered by the Slitheen, for what the Doctor did to another branch of their family.
