'Riverdale's Showrunner Teases There Are Dark Similarities Between Betty Cooper & Brother Chic

Chic Cooper finally made his debut on Riverdale last night — and he’s totally creepy!

After Betty (Lili Reinhart) saves him during one of his “fantasy fulfillment” jobs and takes him back to the Cooper household, he gets even more creepy by watching Betty sleep.

Showrunner Roberto Aguirre-Sacasa says that the Coopers might start to regret letting Chic (Hart Denton) into their home and lives.

“Like anything in Riverdale, there are going to be good things and bad things,” he shares with Glamour mag.

“In the end, I’m not sure. But I will say that we’ll find out next week what Chic was doing in Betty’s room.”

On top of that, Roberto added that Betty and Chic aren’t that different: “We’ll start exploring the darker similarities between the two siblings, which I’m excited about.”

Lili, who spoke with ET, says that she’s just as interested in Chic.

“She definitely kind of goes on the hunt to find information on this long-lost brother that she has and [needs to decide] whether it’s a good idea to try and bring him into to Coopers’ lives now and if that’s a good thing for Alice and Hal and Polly.”

Riverdale airs Wednesdays on The CW.
