Determined to celebrate Bonnie's (Kat Graham) birthday, Elena (Nina Dobrev) convinces Jeremy (Steven R. McQueen) that it's what Bonnie would have wanted. After piecing the broken ascendant back together, Elena, Jeremy and Damon (Ian Somerhalder) attempt to send Bonnie a message, but the situation turns dire when they make an unsettling discovery. Meanwhile, after uncovering Stefan's (Paul Wesley) secret about his great-niece Sarah Salvatore (guest star Tristan Mays), Enzo (Michael Malarkey) enlists a reluctant Matt (Zach Roerig) to help interfere with her life. Elsewhere, Stefan keeps a close eye on Caroline (Candice Accola) as she unconventionally attempts to cope with everything going on around her. Lastly, realizing it might be time to move on with his life, Jeremy contemplates leaving Mystic Falls for good.
