Suze Howard is trying her best at being a single mother to daughters Cassie and Lexi, while the former is struggling with just about everything and the latter is brilliantly observing. She’s known for always having a glass of wine in her hand, much like OTH’s Deb Scott in her early seasons.
Deb went through a similar period of adjusting to single-motherhood after being married to Dan Scott for nearly 20 years. She had some questionable parenting moments throughout the show, but generally just wanted Nathan to grow up to be happy and nothing like his father. Suze and Deb would likely get along great or have a difficult time being in the same room with one another.
Cal Jacobs is one of, if not, Euphoria’s greatest villains. His energy is eerily similar to Dan Scott, who murdered his own brother on season 3 of One Tree Hill.
Cal and Dan are both bad dads who are inherently selfish individuals. They don’t care who they’re hurting as long as they feel like they’re getting revenge. The only difference between them is that over the course of nine seasons Dan eventually is gifted a redemption arc, while Cal has yet to clear his name in any way, and by the looks of it from the season two finale, won’t get a chance anytime soon.
Chris Keller first appeared in season 2 of One Tree Hill as the bad boy threatening the marriage of Nathan and Haley. He showed up with his guitar in tow and was played by real-life musician Tyler Hilton.
Elliot’s character is pretty much the exact same, only he’s a bit more down-to-earth. Elliot befriends Rue and threatens her relationship with Jules — and then ends up hooking up with Jules. His guitar skills are also present on the show, as he is played by a real-life musician, Dominic Fike.
Kat Hernandez started season one of Euphoria being more mild-mannered and taking a back seat to her best friend, Maddy Perez. She soon went through a metamorphosis that elevated her confidence and allowed her to become more like her friends.
Marvin “Mouth” McFadden had a similar journey to Kat’s, standing in the shadow of his best friend Lucas for most of the first few seasons. It wasn’t until he formed friendships with the popular kids that he became more confident in who he was, and got the chance to transform into a main character whose storylines were front and center.
Julian Baker showed up during season 6 of OTH as the movie director who would go on to steal Brooke Davis’ and fans’ hearts. He had a passion for entertainment and was a little bit of a se a fan-favorite for his charisma and ability to tell a story.
Lexi Howard is Euphoria’s Julian, writing and directing her own play and telling the story of everyone around her. Much like how Julian hoped to turn Lucas’s book into a film, Lexi takes Rue’s life story thus far and creates a theater performance so controversial that it resulted in breakups, catfights, and many tears.
Jules Vaughn is a compelling supporting character with huge main character energy. She has a sensitivity and lovingness that makes her easy to root for, much like that of One Tree Hill’s Haley James.
Haley and Jules are both supportive best friends (and significant others) who also know when to draw the line and set boundaries. For Jules, it’s when Rue is clearly relapsing that she realizes she has to step in and get her help. For Haley, it’s calling out Lucas’s unkind, playboy behavior and threatening to end things with Nathan early on if he didn’t become a better brother and person.
