In four seasons, ''Teen Wolf'' has morphed from a guilty pleasure into a bloody thrill ride, making teen-scene royalty out of leads Tyler Posey (as wolf Scott) and Dylan O'Brien (as his friend Stiles). Off screen, the 22-year-old actors are real-life pals who display an easy rapport despite some philosophical differences on things like sports and tattoos. EW visited the set recently for scoop on the sexiest, scariest, most bonkers show on MTV.

As you near the end of season 4, do you ever think back to how much Teen Wolf has changed since that first year?
Tyler Posey All the time. So much of this show is Dylan and me and our relationship, and the thing that blows my mind is how young I felt when we first started hanging out.

Dylan O’Brien And at such a transitional point in our lives, too. We were 18, and it’s only been four years, but I feel like for us that’s a lot longer of a four years than for anyone else.

What do you remember about your screen tests?
Posey That’s where we first really hit it off.

O’Brien He walked in and asked where the bathroom was. And I remember thinking, ”Wow, he’s really comfortable. That’s so badass.”

Posey At this point, I [had been] acting for, like, 12 years, and I never really liked going to auditions because the kids were lame. When I saw Dylan, he had on a DVS shirt, which is a skateboard company, and I grew up skateboarding. I immediately thought, ”Okay, this dude seems cool.”

What should people know about Teen Wolf that they don’t?
O’Brien The show is not what people would expect at all. There has to be such a stigma when you hear the name and what it is and the network it’s on. People don’t immediately give it a chance. They hear Teen Wolf, and it’s like, ”Oh, that movie from the ’80s!”

Posey I think people are afraid to like it…. If they actually check it out, it’s really entertaining.

O’Brien And it’s really aware of itself, too. It’s important to have a sense of humor that makes it easier to believe in the world you’re watching. We’re very aware of the fact that we are a teen werewolf show.

Dylan, are you happy that you don’t play a werewolf?
O’Brien Always. I love the character that I play, and I understand my role, and there are times when, yeah, I’d love to be a werewolf, but sometimes it’s way more awesome when I see these guys having to put on makeup for an hour and a half.

Between the two of you, who has had the weirder fan interaction?
Posey I’m sure you do.

O’Brien I don’t know if I can say this. It’s inappropriate. But it’s pretty funny. I just got it at an autograph signing. They hand you notes and letters and portraits, photo books, little bracelets — all kinds of amazing stuff. But I got an envelope, and the first things that dropped out were two condoms that said something…graphic on them.

Dylan, you’re about to headline The Maze Runner. Are you nervous about what’s to come?
O’Brien If you want to get down to it, this would turn into a therapy session. But I’m really proud of it, and I poured my life into it, and hopefully I’m going to do it for another few years. I’m really excited for people to see it.

What is one interest the other has that you just don’t understand?
Posey He’s really into sports. I want to understand them — I want to be into sports.

O’Brien I actually genuinely don’t understand how tattoos work. He always tries to explain them to me, and I keep confirming with him and he’ll be like, ”No, no,” and he’ll start over again. Like, do they sew it in?

Would you get a Teen Wolf tattoo, Tyler?
Posey I love Teen Wolf. It’s done monstrous things for my life. I’ve thought about it, but I don’t think I’d ever get a Teen Wolf tattoo, and I don’t know why.

O’Brien You could draw the most microscopic S.

Posey S + S equals heart. Stiles + Scott.

O’Brien They would…iron it in?

Posey Yeah, you got an iron?

O’Brien Really?! Oh. I thought you were confirming that burning it in is how it works.

What is your mother’s favorite thing about the other person?
O’Brien My mom’s always had the same opinion I’ve had about Tyler. She’s always just like, ”Tyler’s so sweet! He’s so funny.”

Posey It’s the same thing with my mom. She loves Dylan because she knows how much I love him.

O’Brien We should start spending time with each other’s moms.

Posey When I was younger, I would hang out with my friends’ parents all the time.

O’Brien You know your friends’ parents when you’re kids, but not anymore.

Posey We got a lot of years to work on that, buddy. This ain’t over yet!

Teen Wolf: What We Saw On Set
If it wasn’t clear from the action-packed premiere that Teen Wolf was raising the stakes in season 4 — more deaths! crazier fights! creepier sets! — a visit to the show’s Los Angeles set all but proved it.

”We were definitely going for a Raiders of the Lost Ark vibe this season,” says exec producer Jeff Davis, who’s eager to show EW a new set piece dubbed the Obsidian Room — crumbling catacombs connected to spooky church ruins. There, six cast members (including one whose new look might shock you) are practicing a finale fight scene that will take two days to shoot.

Season 4 has been dark for Scott and his pack (being hunted by assassins is a bummer, after all), but there’s more adventure and less horror coming. The finale will bring the story full circle to the Mexico opener — which is all part of Davis’ master plan to keep fans guessing. ”I like to say that we didn’t jump the shark,” he explains. ”We ate it.”
