'What We Do in the Shadows' boss on what that major death (and rebirth) means for Season 4

Across three years, FX's What We Do in the Shadows has become one of the wildest and funniest shows on TV. But it introduced some major shake-ups at the end of Season 3.

***WARNING! The following contains major plot spoilers for the Season 3 finale of What We Do in the Shadows!***

So yeah... we don't think we'll ever be able to forget the haunting final image from last night's Season 3 finale of What We Do in the Shadows. As much as we try to wash out our eyeballs, the visual of a slimy newborn with Colin Robinson's face will always be there. It's only fitting that such a disgusting visual would lead us into the "Halloweekend" and set the stage for the hit show's fourth season, which is now in production.

Speaking with Deadline about the finale, co-showrunner, executive producer, and writer Paul Simms explained how Colin's (Mark Proksch) rebirth factors into the upcoming episodes. For instance, will the child — which burst out of a dead, 100-year-old Colin — grow into the same energy vampire or will it become something else entirely?

"That’s really the puzzle of Season 4 and what drives it with nature vs. nurture," Simms explained. "It’s a little bit of: Can you avoid your fate? Are you destined to be what you’ve always been or can you make a new start? I know this makes it sound like it’s some heavy, premium cable downer of a show, but it’s all as silly and cartoonish as it ever was before."

"Once you hit 100, you’re automatically tipped to being interesting in some way," added fellow showrunner and executive producer Sam Johnson. "You’re fodder for the local paper. So, I think you can’t continue being an energy vampire even one that’s slightly more interesting than you were before."

And then there's the issue of raising the kid, a responsibility that rests squarely on the shoulders of the sex-crazed Laszlo (Matt Berry). He's the only vampire for the nannying job, having stayed behind on Staten Island while his fellow housemates — Nandor (Kayvan Novak), Guillermo (Harvey Guillen), and his wife, Nadja (Natasia Demetriou) — left for international excursions.

"Laszlo is such a blowhard and just a windbag and an idiot, that the last thing you would want is to entrust into his care a helpless anything," Proksch told Deadline.

"Yet, at the same time, I think Laszlo despite himself having to show Colin a good time during what he thought was his last moments on earth, has developed some kind of affection," added Simms. "Laszlo is supposed to go to England but stays behind because there are beings that require actual care and he has this sense of duty. He also probably has some scientific interests in the experiment of nature vs. nurture. Can he form this Colin into a different creature than what he was?

During an exclusive press round table at New York Comic Con earlier this month, Simms revealed to SYFY WIRE that the Season 4 opener will address the Suez Canal blockage that occurred in the spring.

At the official panel later in the day, the showrunner also teased "the most ambitious episode we've done as far as seeing the other creatures of the supernatural world. You'll have to wait a little for that, but it's gonna be amazing."
