NEW YORK, Sept. 10 (UPI) — Hayes Warner’s character Debbie seems to be the only person NOT obsessed with Homer Gere’s Robert In the FX/Hulu serial-killer thriller, The Shards.

“I love that with my relationship with Homer, too. I love him so much. I say that to him with love for, like, a brother,” Warner, 27, told UPI with a laugh in a Zoom interview Tuesday.

“Debbie is so much smarter than she appears to be and I think that that’s really also a tactic that she uses to kind of navigate and cope,” she explained.

“She really can pick up social cues and understand what’s going on, take information and just lock it away and know that it’s there,” she added. “She can read Robert. She clocks him and she’s like, ‘I know who you are.’ She thinks he’s entertaining and funny when he’s all that and telling about the different places that he’s been worldwide. But I think Debbie’s got bigger plans for herself.”

Created by Bret Easton Ellis and Ryan Murphy, the show wrapped up Wednesday on FX and Hulu with an enormous cliffhanger and, as of Thursday, hasn’t been renewed yet.

It follows wealthy Los Angeles teens through the doldrums of school, tense family energy and thrilling romance in 1981 as a homicidal maniac stalks them.

Robert is the mysterious new guy who shows up at school senior year, immediately threatening Debbie’s boyfriend Bret (Igby Rigney) and trying to break up Debbie’s best friend Susan (Kaia Gerber) and her long-time beau Thom (Graham Campbell).

“That age range is really difficult. It’s her first love. You don’t have much context for what it is and it’s exciting that someone wants you,” Warner said of Debbie and Bret.

“It’s according to her plan of how to be perfect and look perfect, which is not at all her reality and you get to really see that in her family dynamic and in her relationship and her friendships. She wants to look perfect and I think having a boyfriend is a huge plus for her.”

The relationship isn’t as solid as it looks, however, since Bret is cheating on Debbie with her film producer father Terry (Wes Bentley) and one of the male murder victims.

“What’s really devastating as the show goes on and heartbreaking is she has suspicions and she knows more than she gives off, but is not fully understanding it and blaming herself for not being wanted by Bret and putting so much pressure on herself,” Warner said.

“She wants him to want her, but doesn’t understand why he doesn’t.”

Terry’s seduction of Bret, along with other people in his orbit, also destroys his marriage to Debbie’s mother Liz (Evan Rachel Wood).

“With her mother, it’s really complicated,” Warner said.

“[Liz] says, ‘You are me.’ And I think that that’s her biggest fear that they are so similar and her mother’s relationship with her father really does mirror her relationship with Bret in a lot of ways,” she explained.

“And her mother’s big dreams for herself are similar to Debbie’s. So, with her mother, it’s a very complicated ‘love-hate’ relationship filled with jealousy and confusion and fear that they’re going to end up alike.”

It’s different with Debbie’s father, who spoils her with material things, then betrays her by stealing her boyfriend by promising to make his novel into a movie.

“It’s a lot more about trying to prove herself and improve her own path without being thrown into nepotism and trying to show the world that she can do it without him, but also dealing with the fact that he does have a weird reputation and she can pick up on a little bit of that weirdness.”
