Betty Cooper Has the Serial Killer Gene on 'Riverdale' — but Is That a Real Thing?


Let's be honest: there are a lot of storylines on The CW's Archie Comics series Riverdale that are far-fetched. After more than one musical episode, multiple secret siblings, and a cult-like farm, there's nothing that would really surprise us anymore.
