The CW has released a synopsis for “Chapter One Hundred and Ten: Things that Go Bump in the Night”, the fifteenth episode of Riverdale’s sixth season. The episode is scheduled to air on Sunday, May 22nd. All season long, Archie and his friends have been dealing with Percival Pickens (Chris O’Shea), a man who presented himself as a descendant of one of the town’s founders, but as it turns out is an evil force with sinister plans for Riverdale. And despite the best efforts of Archie, Betty, Jughead, Tabitha, and others to stop Percival from getting a hold on the town, they keep getting defeated at every turn. The latest episode saw Percival use personal items to gain power over them, though they were ultimately able to break free of that and from the sound of things in this new synopsis another plan to stop Percival fails as well.
