The Vampire Diaries 5x20 "What Lies Beneath" - When Tyler (Michael Trevino) turns up at the Salvatore house with the news that Markos' (guest star Raffi Barsoumian) plan to break the witches' curse puts Stefan (Paul Wesley) and Elena (Nina Dobrev) in imminent danger, Damon (Ian Somerhalder) suggests they hide out in the remote cabin once owned by Caroline's (Candice Accola) father. Once there, it becomes obvious to Caroline that Stefan and Elena are keeping a secret, so Damon (Ian Somerhalder) comes up with a parlor game designed to expose the truth. A ghostly presence at the cabin uses violence and fire to make itself known. Meanwhile, Matt (Zach Roerig) takes charge of Tyler's plan to get information from one of the Travelers, and Bonnie (Kat Graham) continues to keep the truth about the Other Side from Jeremy (Steven R. McQueen), despite warnings from Grams (guest star Jasmine Guy). Joshua Butler directed the episode written by Elisabeth R. Finch & Holly Brix (#520).
