JEREMY MAKES A DANGEROUS MISTAKE — Elena (Nina Dobrev) decides to take matters into her own hands and offers a tempting incentive to Rose (guest star Lauren Cohan) for her help. When things take an unexpected turn, however, Rose calls on Damon (Ian Somerhalder) to deal with the plan Elena has set in motion. Jeremy’s (Steven R. McQueen) reckless attempt to help Bonnie (Katerina Graham) retrieve the moonstone lands him in a life-threatening position and forces Stefan (Paul Wesley) to put himself in danger. Bonnie and Luka (guest star Bryton James) form a closer connection. Tyler (Michael Trevino) shows Caroline (Candice Accola) the Lockwood cellar, where she makes a discovery that leaves them both terrified.
