"Lessons" is the first episode of the seventh season of the television show Buffy the Vampire Slayer. Dawn finds vengeful spirits in the new Sunnydale High while Giles is rehabilitating Willow in England. Plot In Istanbul, a dark-haired girl is pursued through an arched hallway by two people in hooded cloaks. After trying various escape routes, she is trapped in a dead-end. She sees a drain pipe and uses it to scale the building, barely escaping the duo and easily climbing up to the roof. There, another hooded figure is waiting and pushes her off the building.
