Rose

A vampire named Trevor takes Elena to an abandoned house, where she meets Rose, another vampire. When Tyler witnesses Caroline's abilities, she reveals that she is a vampire. Elena overhears Rose and Trevor arguing about a vampire named Elijah. Using a spell, Bonnie locates Elena. Elena tries to extract information from Rose, who tells her that Elijah is one of the "original" vampires. Rose and Trevor are using Elena, the Petrova doppelgänger who is the key to breaking the curse, as a bargaining chip. Elijah arrives, and Rose offers him Elena in exchange for their pardon. Elijah agrees but kills Trevor. Elena tries to stall Elijah by saying that she knows where the moonstone is, but he compels her to tell him its location. Stefan and Damon arrive to fight with Elijah and stake him. Elena's vervain necklace remains at the house. Later that night, Damon is in Elena's bedroom with her vervain necklace in his hand. He tells her that he loves her but doesn't deserve her, and that Stefan does. Then he compels her to forget what he said. In the abandoned house, Elijah pulls the wooden stake out of his chest.
