Nina Dobrev & Paul Wesley: Bitter Ball on 'The Vampire Diaries' Tonight!

Stefan (Paul Wesley) and Katherine/Elena (Nina Dobrev) share a dance in this still from tonight’s episode of The Vampire Diaries.

In “Total Eclipse of the Heart,” hoping to help everyone move past recent traumatic events, Caroline (Candice Accola) convinces Elena and Bonnie (Kat Graham) to attend Whitmore College’s “Bitter Ball” for broken-hearted students.

Bonnie is intrigued with a fellow student named Liv (guest star Penelope Mitchell), who appears to be dabbling in witchcraft. Tyler (Michael Trevino) starts to worry about Matt’s (Zach Roerig) relationship with Nadia (Olga Fonda).

After making a disturbing discovery, Stefan has a frustrating conversation with Damon (Ian Somerhalder) and Enzo (guest star Michael Malarkey). Dr. Wes (guest star Rick Cosnett) struggles to continue his research project with help from a new benefactor named Sloan (guest star Caitlin McHugh).

Still bent on revenge, Damon and Enzo resort to violence to convince Bonnie and Jeremy (Steven R. McQueen) to help them, but their plan takes an unexpected and horrifying turn.
