The Last Dance
Original vampire Klaus forces captured Katherine to torture herself. Meanwhile Klaus takes henchman witch Maddox’s advice to possess Alaric’s body and use his history teacher job as cover to work on the school-kids and attend the high-school 1960s theme dance, where he hopes to tempt Bonnie to overexert her hundredfold witch powers against an unbreakable charm until she dies. Jeremy mistrusts Bonnie’s assurance she can cope and consults Damon, who doesn’t even confide in Stefan, to brilliantly mount an elaborate trap. Matt teams up with the sheriff for Caroline’s sake.
