Ross Mathews has been a massive fan of 90 Day Fiancé for over a decade. Now, he’s stepping in as host of the latest Single Life Tell All, which he promises will be full of “twists and turns.”

Mathews, 46, is marking his 25th year on television by hosting the 90 Day: The Single Life season 5 Tell All — a role he calls his “dream gig” after being obsessed with the show.

“I do feel like the super fan who won the golden ticket,” the host tells PEOPLE.

Mathews promises there will be “updates galore” during the spicy two-part event, where he says secrets will be revealed that even he wasn’t privy to. Anyone hoping for a shocking Tell All, he says, is “going to be thrilled.”

“This Tell All, we leave no stone unturned,” Mathews says. “We really go there. Nothing was off limits and I really tried to get answers.”

Mathews has grown quite familiar with 90 Day Fiancé over the years, having watched the reality show since it premiered in January 2014. “There’s something about this show that really reads as authentic,” he says. “And maybe it’s because I also am an optimist, so I’m truly rooting for people. I love seeing people fall in love.”

So when the opportunity came for Mathews to host the latest Single Life Tell All, he didn’t hesitate to accept the offer, which he called “a dream come true.” The host has “such respect” for both the show and Shaun Robinson, who began hosting 90 Day Fiancé Tell Alls in 2016 and was “grateful” to step in when asked.

Now, he just wants to “make the fans proud.”

“I am a fan. And so I took it very seriously,” Mathews says. “But I also knew that I would have so much fun doing it. It was like a front-row seat to my favorite show.”

As host of the upcoming Single Life Tell All, Mathews says his goal was to “be respectful” while pushing for “answers and accountability … and really the truth.” But as surprising as season 5 of The Single Life was, he promises the Tell All is even more shocking. “My jaw [and] all my chins were on the floor multiple times,” he says.

There is one moment at the Tell All, according to Mathews, that he “didn’t even see coming,” during which he had to “set my cards down.” He still “loved every second” of hosting and felt “surprisingly comfortable” in the host’s chair.

“The stuff you’ve been yelling at the TV, that I’ve been yelling too, I think we’re finally going to get resolution,” Mathews says. “And if not resolution, at least an explanation.”

As for whether viewers can expect to see more of Mathews in the 90 Day universe, he says, “Who knows? I would say, stay tuned. Dot, dot, dot.”
