On a date with both Betty and Veronica, Archie's car is attacked by a werewolf, and after the three retreat back to Pop Tate's, Reggie happily reveals that it was a joke, and that he had been dressed as the monster. He's quite proud of his prank, but the next day, the police come by Riverdale High. There have been some disturbances around town, and the culprit was a werewolf. Archie refuses to back up Reggie's alibi, and so the prankster is taken off to jail. And later, a werewolf attacks again, wearing Reggie's letter jacket. It seems that Reggie really is the culprit, after all...or is he?
