On Riverdale, Archie Andrews was struggling with the shocking murder of his former lover, Ms. Grundy, on top of the fact that he's already been on edge ever since a masked killer shot his dad, Fred Andrews.
"The autopsy showed that she was strangled. With something the killer grabbed on hand. A cello bow, of all things. There was a struggle. She fought back," said Alice Cooper to Archie. After learning how Grundy was murdered, Archie's mind immediately started racing until he, ultimately, came up with a theory that the mysterious masked murder who shot his father was also the person who killed Grundy, and it all happened to target him. At the police department, Archie explained his relationship with Grundy to an officer, sharing, "We were close. And I'm thinking... He found out about me. Ms. Grundy was killed with a cello bow. I gave her one before she left Riverdale. I'm betting it's the murder weapon. Can't you see, he's sending me a message."
Archie continued to be on edge throughout the entire episode, even attacking his friend Reggie who tried to pull a prank on him. Reggie then made a comment to Archie, "What if I had been the guy?" asked Reggie. "You would have just tackled him? He has a gun, Andrews. He's shot people. Only a dumbass lunatic brings a baseball bat to a gunfight," which had Archie thinking of a new plan.
At the end of the episode, Dilton Doiley gave a gun to Archie, who says, "I'm not crazy, the guy's still out there. It's just for protection."
Archie wasn't crazy. The mysterious killer was still out there, and this week's episode had another shocking ending that really drove fans crazy when the masked killer was seen walking up to Moose and Midge hooking up in a car and shot Moose!
