'The Vampire Diaries' Season 5 Episode 13 Spoilers: Enzo and Damon Go on a Bloody Rampage [Video]

Now that Enzo is back on the scene, he and Damon will partner up to raise hell on an all-new episode of "The Vampire Dairies" this week.

Last week on the show, TVD fans saw the return of Enzo and witnessed Damon reverting back to his sinister side. Plus, Katherine continued to spice things up while in possession of Elena's body.

In this Thursday's episode, entitled "Total Eclipse of the Heart," Damon and his devilish former cellmate, Enzo, will go on a deadly rampage in Mystic Falls. Whitmore College will also host a "Bitter Ball" dance and Stefan will make a "disturbing discovery" that will hopefully lead to the revelation that Katherine is in control of Elena's body.

According to Hypable, a synopsis of Episode 13 reads: "Hoping to help everyone move past recent traumatic events, Caroline convinces Elena and Bonnie to attend Whitmore College's 'Bitter Ball' for broken-hearted students. Bonnie is intrigued with a fellow student named Liv, who appears to be dabbling in witchcraft. Tyler starts to worry about Matt's relationship with Nadia. After making a disturbing discovery, Stefan has a frustrating conversation with Damon and Enzo. Dr. Wes struggles to continue his research project with help from a new benefactor named Sloan. Still bent on revenge, Damon and Enzo resort to violence to convince Bonnie and Jeremy to help them, but their plan takes an unexpected and horrifying turn."

In a teaser video of the upcoming episode, everyone from Nadia, Katherine and Stefan seem to be talking about Enzo. However, Stefan is not impressed when he meets him face-to-face and quips to Damon that he and Enzo are "murder buddies."

The promo video also teases the 1980s-themed college dance in which Stefan is seen dancing with "Elena" who asks him, "What did Damon do now?"

In another clip, Stefan and Enzo go head-to-head and Stefan demands tells him, "Leave my brother out of it," adding, "What I do to you, Enzo, will be final."

There may also be potential for Stefan and Caroline to hook up later in the seaon. Executive producer Julie Plec told TV Guide that, "Caroline and Stefan are really beautiful friends and we'll continue to shine that beautiful friendship. We'll see if it evolves into anything more or if each of them go in their own direction."

S5E13 of "The Vampire Diaries," "Total Eclipse of the Heart," airs on the CW on Thursday, Feb. 6 at 8 p.m. ET.
