invite them to Caroline's party later. Stefan is not in the mood of partying but Lexi convinces him that they should go. While Stefan gets into the shower, Elena knocks on the door and Lexi calls her in. Lexi is shocked seeing how much she looks like Katherine and Elena is surprised seeing Lexi in a towel and knowing Stefan is in the shower, believing that the two of them slept together and leaves. Lexi immediately runs back to the bedroom and ask Stefan what is wrong with him and why is he after a girl who looks like Katherine's twin sister. Stefan reassures her that Elena has nothing in common with Katherine and Lexi sees that Stefan is really in love with Elena. Stefan stops by Elena's house before he goes to the party to ask her what she wanted to talk to him about. He realizes what Elena thought seeing Lexi and he explains that she is only a friend — his oldest friend — and she is in town for his birthday. Elena is relieved but she still does not want to go to Caroline's party and declines Stefan's proposal. At the party, Caroline asks Bonnie for the crystal, but Bonnie does not give it back. Caroline tries to take it, but it shocks her the moment she touches it. The two of them argue and Bonnie leaves. When later Damon asks Caroline if she got his crystal back and she tells him no, he tells her that she is useless and shallow and leaves the bar. When he gets out he sees a young couple making out, he attacks them, kills the boy and compels the girl. Elena changes her mind and arrives at the party seeing Lexi and Stefan having fun while playing pool. Lexi gets to the bar to order some drinks when she sees Elena. She approaches her and the two of them have a nice talk about Stefan making Elena relax a little bit about Stefan being a vampire, to give him some time and he will soon be totally himself around her. When Lexi goes back to Stefan, Stefan thanks her for what she did. Sheriff Forbes finds the girl who survived Damon's attack and she asks her if she saw anything. The girl nods that she did and the Sheriff asks her to tell her everything. Back at the party,
