Katherine's (Nina Dobrev) mind games are getting on everyone's nerves, but Damon (Ian Somerhalder), Stefan (Paul Wesley) and Elena (Nina Dobrev) realize that her knowledge of Mystic Falls history will help them stay alive. Frustrated with her relationship with Matt (Zach Roerig), Caroline (Candice Accola) finds a new way to get his attention. Alaric (Matt Davis) makes a surprising confession to Jenna (Sara Canning), and Katherine makes a different kind of confession to Damon. Stefan and Bonnie (Katerina Graham) try to convince Jonas (guest star Randy Goodwin) and Luka (guest star Bryton James) that they should all be working together, but Jonas' lack of trust leads to a violent and fiery confrontation.
