***The following contains slight spoilers for 410***

On the newest episode of Evil, premiering today on Paramount+, there’s a hurricane coming, but is it more than just the weather causing it? As Kristen (Katja Herbers) and her daughters prepare, they are joined by David (Mike Colter), Ben (Aasif Mandvi), and Sister Andrea (Andrea Martin). However, that isn’t the only problem when Kristen discovers she has to be worried about her new neighbor. Meanwhile, Sheryl (Christine Lahti) continues on her quest to destroy Leland (Michael Emerson) and is joined by Dr. Boggs (Kurt Fuller) as they wait out the storm together, but are visited by someone, which is just the start of the shocking conclusion to the war between Sheryl and Leland.

During the episode, at the request of Kristen, Dr. Boggs visits Sheryl at DF, and is witness to a man who appears as a demon, but he once again seems to think it could all be in in their heads. According to Fuller, who recently spoke with SciFi Vision, it’s important that what really happens often remains ambiguous. “Once you start reaching conclusions, the show is over,” explained the actor to the site. “…You’ve got to keep the mystery going. You've got to keep the open ended questions going.”

Everything is psychological manifestations to his character. “Boggs does not believe in angels, demons, otherworldly anything,” he continued, saying that Boggs’ explanations have progressively gotten worse over the seasons. “Let's face it, a demon tried to kill [them], but Boggs will not let himself believe that, because it would rock [his world]…He can't handle that, because he's so wrapped up in trying to be the greatest, most world renowned therapist that he can. He’s writing books on therapy. He wants to be a leading intellectual figure in in psychology, and demons and metaphysical things just don't fit that, and he won't allow himself to believe it.” The actor added, however, that he thinks subconsciously Boggs fears that these things could actually exist, but he “won’t go there.”

Fuller also talked about Boggs’ selfishness and if he’s actually a good doctor. “He over prescribes medication all the time,” said the actor. “He's given pills out. His first answer to everything is some kind of psychotropic drug…He only wants to help people, because he wants to be famous. He wants to be famous and respected, and he's so afraid that he's not, and he never went as far and did as well as he thought and as he thinks he deserves.”

For more from Fuller, including if Boggs is worried about the his demonic muse, how the song “Allouette” gets stuck in his head, and more, read the full transcript below. New episodes of Evil stream Thursdays on Paramount+.

SCIFI VISION:   To start out, the one thing I want to ask about is, obviously this show is a lot of times open to interpretation, whether the evil is kind of a physical manifestation and all in their head, or whatever. Boggs is a psychiatrist, so I'm sure he has different ideas. But after what's happening in 410, he's talking about, you know, folie à deux, and things. So, I'm just kind of curious, where do you think he's at now? Does he believe in any of this, or is he still sort of not sure?

KURT FULLER:   Well, I'll say two things about what you said. First of all, in order to do the show, you know, it's very hard; once you start reaching conclusions, the show is over. So, it's sort of like in Cheers. When Sam and Diane actually did the deed on the show, the show ended, because you’ve got to keep the mystery going. You've got to keep the open ended questions going. That's number one regarding the show. Not that you're saying it shouldn't be that way, but I'm just saying that's what I think. And Boggs, his whole life he has been dedicated to the world is the world as it is. All problems are psychological manifestations. I imagine Boggs doesn't believe in God. I play, [it that way], but anyway, I'll tell you, Boggs does not believe in God. Boggs does not believe in angels, demons, otherworldly anything, except that he's seen things that he's trying to explain, but his explanations really have gotten worse and worse and worse as the seasons have gone on. Folie à deux, I mean, give me a break. Give me a break. What we saw, what happened, let's face it, a demon tried to kill [them], but Boggs will not let himself believe that, because it would rock [his world]. He doesn't have the character to have his world rocked like that. I hate to say bad things about my character, and when I act it, I don't think those things, but looking back, now that I've done it, he can't handle it. He can't handle that, because he's so wrapped up in trying to be the greatest, most world renowned therapist that he can. He’s writing books on therapy. He wants to be a leading intellectual figure in in psychology, and demons and metaphysical things just don't fit that, and he won't allow himself to believe it. But I really think that he's extremely afraid that that might actually be true, that if you could pull his subconscious out, there would be a huge amount of fear that these things are real, but he won't go there.

He let a demon in to write his book originally, when he was trying to get his ideas, his demonic muse. Is he then, not, I guess, worried that he did that? Because, well, he kind of gave up his soul, or said he did. Whether he did, I don't know, but…

It's such a great question, and it's a great observation. I've also thought a lot about it, and taking the evidence, you know, every script I take as a Bible, and I don't try and second guess it, but Boggs moves in and out of consciousness about these demons. When he's been overtaken by these demons, and when he had that whole thing last year with the singing and the this and the that, he was fully in it. But once he stopped, it ceased to become a part of his world at all. He never thought about it, talked about it, until the demon came back. The only thing that I can conclude is that when those demons come, Boggs, his whole world, he goes into an alternate reality. When those demons aren't around, and when Leland isn't doing whatever he's doing, I guess, he conveniently, or, just really, he loses the conscious remembrance of and it stays in that alternate world. That's the only conclusion I can draw from the way the way the show has gone.

That's fair. So, he's not worried about it, but maybe he should be. [laughs]

Exactly, exactly.

He's still writing about cannibals and everything else. [laughs]

Oh my God, and that's the other thing. What the hell is he doing? I mean, has he really read that? I mean, I’ve got to tell you, like, when the kid came in, and the kid trashed his work, has Boggs really read it? I mean, does he understand? He doesn't understand what a jumble it is at all. So, the other thing I can think is that it made complete sense to him when he was under that spell, but if he sees it now - you know, you've asked me a question. It's very hard to answer. If he sees it now, why wouldn't he go, “I wrote that?! What?”

Yeah, you have to question if he read it back.

I don't think I have a satisfactory answer for you, but that's the only way I could play it.

No, that's good. I guess the other question is, how important is the book to him? I mean, obviously, I guess, if he didn't believe he was selling his soul, then maybe it doesn’t have as much of an importance as I'm looking at it as, but how far do you think he would go? I mean, how would he go further? I'm just curious what you think?

Go further in what regard?

I don't know. I'm thinking, is there further than selling his soul? I just mean, he seems to be willing to do anything to get his book out there, to get it public.

I think if Boggs was the star of this show, and they spend all their time on what's going on with Boggs, he would have an enormous struggle if he had to kill somebody for his book. He would seriously consider it. I don't think he would. I don't think he would kill anyone, but he would go certainly farther. Yes. He is desperate to be respected and admired. Desperate.

Yeah, definitely. Now, a silly question, how much was that “Allouette” song stuck in your head?

It's still in my head. If I'm just sitting around and my mind wanders, I start singing in my head. I can't get it out of my head. I don't know why. I mean, it's not like a song I sang as a child. I didn't grow up in Paris, but it is one of those tunes that is sort of primal. I really can't get it out of my head. It doesn't haunt me, I'll tell you that, but it does come in and out, yes.

I think it did to viewers too.

I know, I know, very creepy. One of those songs, you know, it's not even that great a tune, really, but it does stick with you.

Definitely an earworm. So, back to what you were saying before about how as you play him, that you have to kind of be open with whether it's real or not, whatever, does that make it harder, though, as a performer, to not be able to have one specific side to be on?

I played a character in Supernatural who was horrible, but who had a sense of humor. So, I just played him like a guy who thought he was the funniest, most entertaining person on earth. Boggs has a lot going on, but he really wants to help people, and if he helps enough people, he will become famous. So if you find the the positive thing that your character is doing, and you play that, everything else they do, bad, horrible, it's justified and it makes sense, and people will still watch you, because you haven't made them hate you, even though you're doing horrible things. So, I just found the good in Boggs every time and played that. You know, it was hard when I was a younger actor, but once I figured that out - actually, Tom Hanks, I did this movie called The Bonfire of the Vanities, and he told me that, and I've used it ever since, so I can't even take credit for that.

I'm sure it helps, especially with a thing like this. So, I know obviously, like you said, he really wants to help people, but I feel like maybe he needs to, I don't know, be more careful, have better security. Because he’s maybe a good doctor, in one sense, but in the other sense, well, he's not kept their privacy very well.

No, and is he a good doctor? He over prescribes medication all the time. He's given pills out. His first answer to everything is some kind of psychotropic drug. I mean, he’s given Kristen all this medication. He gave Sheryl all this medication that didn't help them. I don't know if he's a great doctor. He thinks he's a great doctor, but he's disorganized. I just feel like he's not a centered person. And really what he wants to be, he only wants to help people, because he wants to be famous. He wants to be famous and respected, and he's so afraid that he's not, and he never went as far and did as well as he thought and as he thinks he deserves. I just think his eye is not on the prize. His head is in the clouds, and he's not paying attention to his his practice, really. So, you're absolutely right.

Yeah, I was going to say a little bit of selfishness in with that altruism there. [laughs]

You think?

Yeah, just a bit.

Well, you know what? That's the other thing I love, that all these characters are flawed. They should be. We all are flawed. So, why not?

Is it sometimes hard to, I guess, balance - obviously some of the things in this show could go very over the top, and you have to reign it back a little bit sometimes. Is that a hard thing to do? Or do you enjoy just kind of going all out? How do you feel about that?

I'm afraid of going all out, because I can chew the scenery, if they let me. I really I can. I'm one of the great over-actors of all time, and so I have to watch that. When things are very, very potent, when they're written very powerfully and huge things are happening, you don't have to play them that big, because the visual is there. So, yeah, it's hard. Actually, it's hard, but it's the way it has to be, because when the picture and the story is so intense, if you match all that, it's too much. It's overkill. So, really, you have to - the old, less is more thing. Yeah, it really applies on a show like this.

I like the tone, though, because it's always something different. Half the time you're laughing, and half the time freaked out.

Yes. Without the humor, this show, I don't think would work. I think that was the brilliant idea that the Kings added, and I think it's fantastic.
