Michael Malarkey

The Vampire Diaries villain Enzo may be dead, but his revenge is only just beginning.  

After learning that the love of his life, Maggie (Heather Hemmens), was killed by his own best friend Damon (Ian Somerhalder), Enzo (Michael Malarkey) flipped the 'ol humanity switch so he could exact retribution without a care in the world. After battling it out with Stefan (Paul Wesley), Enzo died, but fortunately for him, he can still make moves from the crumbling other side — and no one, not even Caroline (Candice Accola), is necessarily safe.

"Now that he's flipped his switch, he has no ties holding [him] to caring about any of these people," Malarkey tells TVGuide.com. "He's a time bomb waiting to explode. He's feeling rather anarchist, so anybody who's in his way — off with their head. Yes, he's got this vendetta with Damon and Stefan, but at the same time, if anybody gets in his way and stops him from getting what he wants, he's going to be remorseless. So that's dangerous."

Since Damon isn't yet aware of Enzo's death, the beginning of Thursday's hour will find him doing what he can to locate his former ally. Despite Damon's effort, Malarkey says, "He doesn't see that moment, but even if he were to, he'd be like, 'Mate, you've had three strikes, you're out.' Enzo has had it up to here with him doing wrong. So if there is a chance for redemption in their friendship ,it's going to be quite a challenge to achieve."

As Enzo gets comfortable on the other side, he'll quickly realize that everyone around him is coming to terms with the fact that their world is about to permanently destruct. "There are rifts happening and everyone on the other side is freaking out," he says. "Enzo is quite quick to join the club, like, 'Maybe this isn't a good place to be.' He meets some strangers along the way who he may or may not use to get what he wants [which is] to get out of there."

Although he had an ominous presence when he joined the show earlier this season, Enzo quickly became a fan favorite, which isn't an easy task for newcomers on a series with an established fan base. "I'm absolutely honored people have taken to him so well, especially since playing a villain sometimes people are less understanding and just want to see good stuff happen and people make out," Malarkey says. "I think part of it is that he's a bit of a renegade. The accent apparently helps. Also he's charming and witty, and it's important to keep that spark and fun in the show and he's brought a bit of that out."
