But as he tells the story, it almost sounds like fate played a hand in him landing the role of Tyson, Percy's (Walker Scobell) half-brother who is a Cyclops. "When I first read the books, I was 12 or 13 years old, and I became obsessed with Greek and Roman mythology," Diemer told The Hollywood Reporter on the show's set in late 2024, during the filming of season two. "Poseidon became a huge thing for me, so I've had this for years."

"It's in a movie I did recently [2024's Absolution, starring Liam Neeson and filmed in late 2022], so it's proof that I didn't just get it when I got this job," Diemer added, laughing. Diemer's necklace is also almost identical to one Scobell has himself. "When I met him for the chemistry read, he walked in with that on, and I had literally, just like a month earlier, bought a silver chain trident from the same company," Scobell recalled. "It was insane." The chemistry read between the two actors apparently went well, as Diemer has integrated seamlessly into Percy Jackson's ensemble in season two. As Tyson, a big (as Cyclopes tend to be) but naive Cyclops whom Percy's mother (Virginia Kull) took in, Diemer plays his childlike qualities while also showing an undercurrent of darkness from having lived on the street. Both have been on display through the first three episodes of season two, with Tyson marveling at the amenities onboard the cruise ship Princess Andromeda - but also building a small bomb to help him, Percy and Annabeth (Leah Sava Jeffries) escape after they're captured by Luke (Charlie Bushnell) and his troops. "I wanted to be really honest and dedicated to the source material and respect the character that he was in [The Sea of Monsters, the second Percy Jackson book], but also use where I am as well and add the complexities of somebody that grows up on the street, somebody that's dealt with monsters for years," Diemer told THR. "I think we found a really nice balance between the innocence and the naiveté, this extremely lovable, heartfelt energy that he moves through life with, and these complexities." The depth with which Diemer can discuss the character is due in part to his training as an actor - which, as it turns out, was another connection to Percy Jackson and the Olympians. Andrew McIlroy is the show's acting coach, someone who executive producer Dan Shotz called "a game changer." He has worked with the entire cast, but particularly the younger stars as they take on the heavy load of leading the series. "When we were coming back for this season, we started doing our reads of [potential] Tysons," Shotz told THR. "This guy, Daniel Diemer, kept rising to the top. And wait, he's actually from Vancouver. This is really convenient. He was really the choice the entire time, and Andrew didn't say a word. Finally I went to Andrew, and I was like, 'Hey, can you look at this tape? This is the guy we're thinking about casting as Tyson.' It was such a big deal because he's such a fan favorite, and so huge for the season. And Andrew didn't say anything until the moment where I was like, 'We're gonna cast this guy, this is the guy.' And then Andrew goes, 'I was his coach.'" Diemer picked up the story from there: "My first ever acting class was with him. He's the reason I became an actor. I was 18 or 19 and was going to university for medicine and had about nine months off before my program was supposed to start. I needed a part-time job, and I had done a music video in high school. I was like, yeah, maybe I can do some acting work on the side for a little bit. Then I thought, no, I should probably take an acting class. I googled acting classes in Victoria [British Columbia], and he was doing a three-day workshop. I took it with him, and we connected. He invited me out to Vancouver, where I did a six-week program with him, just watching all his top students in the city, and I just fell in love with acting through that. I [later] came back and did a month or two with him in person, and that was the start of it
