Stefan (Paul Wesley) and Damon (Ian Somerhalder) are furious when they discover that Elena (Nina Dobrev) has defied them both to make a new ally and take control of the plan to out-maneuver Klaus (Morgan). Disagreement over how to protect Elena leads to growing tension between the Salvatore brothers. Meanwhile, Stefan has his hands full trying to keep a confused and frightened Jenna (Sara Canning) safe. Flashbacks to 1491 reveal Katherine's (Nina Dobrev) introduction to Elijah (Daniel Gillies) and Klaus, along with the origin of the moonstone curse.
