Sleepy Hollow airs its two-hour season finale tonight (8 p.m. ET on Fox) with John Noble returning as Sin Eater Henry Parrish and Victor Garber guesting as the estranged father of Ichabod Crane (Tom Mison). Since Mison — whose character is still trying to free his wife Katrina (Katie Winter) from purgatory while battling evil with Abbie (Nicole Beharie) — and costar Orlando Jones, whose Capt. Frank Irving must answer for the deaths surrounding his daughter’s demonic possession, couldn’t offer too many spoilers about the genuinely unexpected twists that lie ahead, we asked them to reveal a few details about themselves instead. Watch them each take the EW Pop Culture Personality Test below. Then, see what teases we were able to coax out of them.

Bonus fun fact: That bit of trivia on Mison’s IMDB page about his great great aunt being in the circus with Charlie Chaplin is true. “My great great aunt was an acrobat in the circus with Chaplin. They fell in love, went to America, and she had to come back because her mother was sick, and he stayed in America, and that was that,” Mison says. “But then she bought a pub in London on Carnaby Street called The Shakespeare’s Head, and she had a vaudeville theater above it, and she had a singing troupe called the Mumming Birds.”

Finale teases:

• Attention, Ichabbie fans! There will be a few moments that can be “hijacked by the shippers,” Mison says: “I’d never heard the term ‘shipping’ before [this show],” he admits, with a laugh. “I had to Google it. I thought people were insulting us. ‘Tom Mison — ship. ‘It’s like, ‘I beg your pardon.’ But it’s good apparently.”

• We’ll hear more about Jeremy, Ichabod and Katrina’s son, who had his heart stopped by Katrina’s coven and was buried: Like us, Mison was surprised that the death of Jeremy’s Golem was such a tearjerker in episode 110: “Who’d have thought that you’d get emotional about, basically, a 6½-foot turd in a little loin cloth,” Mison says, laughing again. “We had brilliant special effects makeup, and I was surprised at how moving Derek Mears, who’s inside the costume and also reappears as Moloch [in the season finale], was. You can see his performance through half an inch of makeup, which is very difficult — hearing those pathetic little noises he made as he was lying down on a freezing floor in the middle of the carnival.”

• We’ll be exhausted after watching it: “I was exhausted reading it,” Mison says. “Almost every page there’s a massive revelation. It’s one of the most exciting scripts I’ve read for ages. And, of course, there’s large elements of the ridiculous within it.” Adds Jones, “What’s fun about it is, you’ll feel a little bit the way you felt through the pilot: Some parts you’re laughing, some parts you’re scared, some parts you’re trying to figure out what’s gonna happen, and then a left turn happens that doesn’t really seem like a left turn,” he says. “Nobody knows where it’s going. And it’s right in front of you. And you missed it. It’s literally there, and you’re all guessing wrong. I love it.”

• Expect cliffhangers: “The season finale ends on several cliffhangers,” Jones says. “Though it sounds really cryptic right now, when you watch, you’re gonna go, ‘Ohmygod, he was right.'”

Here’s Jones teasing the “devastating” finale while trying to keep a balloon from hitting the floor (we’ll try anything to get people to slip and say too much):

Bonus video: In honor of Noble’s return, revisit his 2013 Personality Test. We could watch him describe the reality TV shows he watches when he’s alone for two hours.
