There's a winking irony in Kenworthy's character, Chet: He's an athlete who got disqualified Olympics because of drug use, which subsequently led to a buildup of rage and a drinking problem. That doesn't sound like someone who definitely wouldn't commit murder.
It's partially because of his Olympics embarrassment that he decides to haul ass out of the city to Camp Redwood with his friends from aerobic class, Xavier (Cody Fern), Montana (Billie Lourd), and Ray (DeRon Horton). When the jazzercisers are discussing their plans to escape the City of Angels -- and the home invasions and attacks by Richard Ramirez, AKA the Night Stalker -- Chet is introduced to Emma Roberts' Brooke. He gives her a smoldering look, the two lock eyes, and he brings charm deserving of a gold medal as he rushes to her defense when Xavier badgers her into spending the summer at Camp Redwood.
It's the sort of meet-cute that indicates the start of a more serious relationship. Sure enough, when the season was first announced, Ryan Murphy billed Kenworthy as Brooke's boyfriend, which could have been a sleight-of-hand move to hide the character's true role. But it looks like these two are set to get a lot closer, and with Brooke featuring as the main focus of the ensemble, Chet will likely play a crucial role, too.
