'What We Do in the Shadows' star reveals there's a 'very disturbing' twist on the horizon for his character this season

• "What We Do in the Shadows" star Mark Proksch teased a "disturbing" twist coming this season.
• Proksch, who plays energy vampire Colin Robinson on the show, says the twist is also "hilarious."
• "It's definitely something that will shake the show up a little bit," the actor told Insider.

Mark Proksch teased a "very disturbing" but "incredibly hilarious" twist involving his character Colin Robinson on this season of "What We Do in the Shadows."

Proksch plays the "energy vampire" on the FX comedy, which premiered its third season on Thursday. Colin usually manages to avoid any conflicts with his vampire roommates, but the actor said that there's a "big twist" involving his character at the end of this season.

"I know what happens to my character, which is rare on the show. They usually play it pretty close to the vest," Proksch told Insider in a recent interview.

According to the actor, the nature of the twist involving Colin was the reason he was made aware of his character's fate ahead of time.

"It's going to be very disturbing, I think, for a lot of people," Proksch revealed. "But I think it's also going to be incredibly hilarious, and definitely something that shakes the show up a little bit."

"I have no doubt that they're going to kill it when it comes to the writing," he added.

Season two of "What We Do in the Shadows" ended with a major cliffhanger - Nandor's human familiar, Guillermo, was revealed to be a vampire slayer who's actually the descendant of Professor Abraham Van Helsing (a famous monster hunter).

And when Guillermo outed himself as a slayer in order to save Nandor, Colin, Nadja, and Lazlo from being killed by the vampire council, the famously finicky housemates were left to determine his fate. (Thankfully, they decided by the end of the season premiere to let Guillermo live.)

Proksch also told Insider that there were several celebrity cameos happening this season, but couldn't divulge who exactly would make an appearance on the show.

The first two episodes of "What We Do in the Shadows" are currently streaming on Hulu, with new episodes premiering Thursdays at 10 p.m. ET on FX.
