Stefan and Klaus team up once again to stop Connor, but Klaus leaves to find Alexander's sword. Connor takes Jeremy, Matt and April hostage. April who doesn't know of vampires yet, and so thinks Connor is delusional and is naturally scared of him. Stefan and Damon argue on the best course of action. Damon is knocked unconscious and the situation turns violent when one of Klaus's minions is sent to stand up to Connor. Meanwhile, Shane is trying to get Bonnie to get over her guilt via hypnosis, which at first appears not to work when he tries to get her to light a single candle, but when Bonnie opens her eyes she sees she lit every candle in the room. Jeremy tries to talk to Connor, who explains a friend of his was once turned into a vampire but he had to put that friend down, and then the tattoo began to appear. Elena breaks in and attacks Connor, but he is taken away by Stefan. Damon catches up to them and confronts Stefan on why he doesn't kill Connor and he explains Connor is the key to a cure. When Connor makes a run for it, the brothers witness him being killed by Elena, much to her guilt.
