Bear with us here. A fan theory that first surfaced on the internet (naturally) had Molly Ringwald's character as the big baddie of season 2, and it's steadily gaining momentum. It's also not as implausible as it might sound. While the theory didn't state in what capacity Mary Andrew's villainy would occur, it's pretty easy to draw logical connections from the killings that could point to her being the one who's hired a hitman. At the end of season 1, Mary wanted Archie to move back to Chicago and he refused. Did she have Fred shot as an act of revenge? Did she also find out about Miss Grundy's affair with her teenage son and decide to take matters into her own hands? Both of those are plausible enough, but why would she be looking to take out Moose and Midge...unless it was to throw us all off the scent.
Again, the killer does appear to be male owing to the size and build, so we're going with a hitman in this guess. Hermione has been massively on edge about her husband returning to town, and was definitely anxious about him catching up to Fred. If you watch back the first episode of season 2, she's shady as anything when she arrives at the hospital with Veronica to offer comfort. Is that because she ordered the shooting? She's also pretty unhappy about Veronica's attachment to Archie; anything that seemingly influences her daughter too positively (such as her friendship with Betty, or her love for Archie), she immediately wants Veronica to leave behind. In the Lodge family, it's all about toeing the family line, and Veronica won't do that while Archie is still on the scene. So, is Hermione aiming to avoid conflict with Hiram by removing Fred from the scene, and also trying to bring enough turmoil and upset to Archie's life that he'll eventually break it off with Veronica?
During season 1, Reggie was unfailingly decent to Archie - something that irritated longtime Archie Comics fans, as they're renowned for their rivalry. While he didn't feature in the first episode of season 2, he was featured in episode 2 when he supplied Archie with jingle-jangle to keep him up at night. Again, it seemed as though he was doing this only to help a friend out, but is there an underlying motive? Does Reggie have a long-held grudge against Archie that has now come to fruition? That would give motive to the shooting of Fred, the killing of Miss Grundy (did she spurn him, perhaps?), and the shooting of Moose and Midge... especially if he is worried about being caught dealing jingle-jangle which could, in turn lead to the police detecting his other crimes.
BONUS: Kevin Keller
This was going to be a list of five guesses... but it's also occurred to us while writing that Casey Cott, who plays Sheriff Keller's son, has been promoted to series regular this time around. Thus far, he's not been given a lot to do and it's about time he got a decent storyline. He also has green eyes. Whoever is carrying out these killing attempts has made a crude hood with cut out eyes - it doesn't look very slick. A homemade attempt from an inexperienced individual? Watch this space...
