Cheyenne Jackson plays phobia specialist Dr. Vincent Anderson on FX's "American Horror Story: Cult," airing 10 p.m. Tuesday.

This article contains spoilers about Tuesday's episode of "American Horror Story: Cult."

Brooksfield Heights, Michigan has a new vacancy for a phobia specialist.

On Tuesday’s “American Horror Story: Cult,” Dr. Vincent Anderson, played by Cheyenne Jackson, was dramatically mutilated and then executed by his unhinged young brother Kai (Evan Peters), after Vincent threatened to institutionalize the aspiring cult leader.

As with seasons past, Jackson said in an interview Tuesday he only knew so much going into “Cult." In fact, the only specifics he got about Vincent came in a single, light-on-details text message from co-creator Ryan Murphy.

"We know only what we need to know," Jackson said.

With Vincent now the latest of Kai's victims, Jackson is now left in the dark about where the season ends.

“I didn’t get the final script, which I kind of love,” he said. “Now I can just be a fan.”

Jackson said “Cult,” which leans heavily on the contentious aftermath of the 2016 presidential election, has been his favorite season of the FX anthology series to shoot because it is so unsettlingly and often uncomfortably bound to the present.

“The subject matter has been the most relatable and frankly frightening because there are no supernatural elements,” he said. “This is about those people who are diametrically opposed to what you believe in and I think that is a real, clear and present danger right now in our society.”

When he was first introduced, Vincent was a calming -- if not suspiciously so -- presence for Sarah Paulson’s phobia-stricken Ally. If viewers were under the impression Vincent was possibly prescibing a dose of subtle antagonism, Jackson said that was intentional.

“I didn’t know early on whether Vincent was in on anything,” he said. “But the producers asked me to play things in a little bit of a grey area.”

Ultimately, Vincent wasn't a shadowy part of Kai's murderous cult. Instead, the protective older brother just thought his blue-haired sibling was starting a grassroots movement empowered by his recent city council win.

“Cult” marks Jackson’s third consecutive season in the “AHS” troupe of actors, first playing fashion designer Will Drake opposite Lady Gaga in “Hotel” and then ambitious reality show producer Sidney James in “Roanoke.” In the former role, Jackson said his admiration for Gaga and co-star Kathy Bates made his debut in the series a bit rocky.

“I was really scared and I didn’t have much fun until about halfway through because I was in my head,” he said, adding eventually just had to go all in.

But with “Cult,” he is now one of the show’s veterans, here to usher in a new class of actors including Billie Lourd and Billy Eichner.

Jackson praised the chemistry that builds by working with a consistent group of actors, and kept fresh and unpredictable by the show's constant evolution season to season.

“It is a great challenge and opportunity,” he said. “I've known Sarah for 10 years. When I see she is in a scene with me, you know that she is going to come out fully, like she’s being shot out of a cannon. You just have to be ready and prepared.”

Jackson is likely referring to their explosive final scene together in Tuesday's episode is explosive, where Paulson's Ally violently threatens Vincent.

“AHS” has been scaring -- or at the very least, disturbing -- audiences for seven seasons, but Jackson said he doesn't succumb to the scare tactics easily.

However, in doing research to play Vincent, he did find himself a little shaken whenever he stared too long at the show’s porous imagery -- meant to trigger a phobia of holes called trypophobia.

Jackson might not be in the know about this season's endgame, but he was able to tease the episodes leading to the climax will build upon all that Kai and his acolytes have been working toward.

“The narrative of Kai and this locomotive that everyone either gets on or gets out of the way of definitely has a unbelievable payoff that’s emotional,” he said. “As a viewer and just a citizen in the world today, I think it is pretty timely and scary.”

“American Horror Story: Cult” airs 10 p.m. Tuesdays on FX.
