TYLER (Michael Trevino) RETURNS TO MYSTIC FALLS—Elena (Nina Dobrev) and Damon (Ian Somerhalder) set off together to make sure Jeremy (Steven R. McQueen) is safe in Denver, and to see if his special abilities can help reveal the information they need about ancient vampire bloodlines. It doesn't take them long to learn that Jeremy has been hanging with the wrong people. Stefan (Paul Wesley) and Klaus (Joseph Morgan) both go to brutal extremes in their search for the missing weapon. Caroline (Candice Accola) is thrilled when Tyler returns to town, but Tyler soon suspects that something has been going on between Caroline and Klaus. Matt (Zach Roerig) has his hands full trying to keep Rebekah (guest star Claire Holt) busy organizing the school's upcoming 1920s Decade Dance.
