Riverdale [1] is about to go full-on Glee. On Tuesday, we got a sneak peek of a scene from the upcoming episode, and it's really something. After Archie gets locked up in juvenile detention for Cassidy's murder [2], Veronica decides to surprise her man with a little impromptu dance by the Riverdale [3] Vixens. Because nothing says true love like a choreographed dance number, right? As the girls dance and sing along to Elvis Presley's "Jailhouse Rock," Archie and his jail mates are spotted losing their cool at the fence. Yeah, really. If you thought Betty's strip tease from last season [4] was uncomfortable, just wait until you see this.
