'Riverdale' Boss Roberto Aguirre-Sacasa Teases Cliffhanger On Tonight's Season Finale

Riverdale season four is coming to an end early tonight (May 6)!

The CW series’ finale lands on the 19th episode, out of 22, due to production being shut down because of the pandemic.

Showrunner Roberto Aguirre-Sacasa opened up about making this episode the finale, the episode’s cliffhanger, and where it will pick up next season.

“We had gotten through shooting more than half of episode 20, which is our big prom episode, [before production shut down],” Roberto told ET. “When it became clear that we weren’t gonna be able to finish the season, the first thing I kind of did was look at episode 20 to see if we could cobble together an episode from that.”

“And though we actually shot the prom, where a lot of dramatic stuff happened, there were so many emotional scenes with Archie and Veronica and Jughead and Betty that it felt like we just couldn’t quite do it,” he added.

Roberto shared that after watching a first cut of the episode, “It felt like we could definitely treat 19 as our finale and then senior prom would be our season premiere next year.”

“It has a really disturbing, kind of, gruesome cliffhanger,” he continued, before praising Mädchen Amick, who made her directorial debut with the episode.

“19 is so fun and turned out so well and Mädchen directed for the first time and she did great!” Roberto shared. “It’s such a fun teenage type of story that it felt like, ‘Oh, this will be as satisfying to the fans as any episode — or more satisfying than a lot of episodes.’ So we felt good about it.”
