Riverdale season 2 has long been teased as much darker than the show's freshman season, which is saying something considering that season 1 dealt with Clifford Blossom murdering his own son. Season 2 was set up during the season 1 finale, when Fred Andrews was shot during a supposed robbery at the diner.
Though Fred lived, Miss Grundy wasn't so lucky. Now residing over in Greendale, she was strangled by the same person who shot Fred, and it's now clear that whoever the man in the black hood is, they're deliberately targeting people close to Archie. At the end of season 2, episode 2, Moose and Midge Klump were busy getting high off jingle-jangle when the masked killer shot them both. Fortunately they survived, and in this week's episode of Riverdale the shooter was kind enough to drop off a big clue, in the form of a letter sent to Alice Cooper:
This is the Black Hood. I am the man who shot the adulterer at Pop's. I killed the child predator at Greendale. I shot the drug and sex addicted teenagers at Lover's Lane. Riverdale is not innocent. It's a town of hypocrites, degenerates, and criminals. My wrath is the price of your lies, your secrets, your sins. I will not stop. I cannot be stopped. I am the wolf. You are the flock. This is the bloodletting. You will hear from me again.
Very dramatic - but not necessarily the truth. If the man in the black hood has a different motive for his actions, the "sinner-targeting serial killer" story could just be a cover-up to disguise the real reason that the victims were selected. Perhaps Fred, Moose and Midge survived because the man in the black hood only really wanted Miss Grundy dead, but wanted to make her murder look like part of an attempted killing spree.
With little about the killer yet confirmed, let's break down a few characters in the show who could be the man (or woman) behind it all.
Before we get started, let's point out that to only suspect characters who have green eyes is silly, because (aside from the fact that colored contact lenses exist), it could well be a hitman acting on someone's behalf... and we already know Hiram Lodge has no qualms about hiring other people to do his dirty work. His motive for having Fred shot is clear; he wouldn't have liked the fact that Fred and Hermione had a fling while he was in prison. But why would he go after Miss Grundy? That's a little more tricky, except that we do already know that Hiram won't warm to Archie through season 2. Could he be going to extreme lengths to make sure the entire Andrews family stay away from his wife and daughter? Although the character has only appeared in 2 episodes so far, it's very clear that he's not someone to cross, and he has few qualms about lying, cheating and deceiving others to get his own way.
If we're going to base a guess on the look of the killer, then Hal Cooper fits the bill, even if the motive is unclear. There's been something shifty about him throughout season 1; this is the man who sent his young daughter off to a convent to have her baby given up for adoption, all because he was trying to hide a deep family secret. But why would Hal go after Fred Andrews? It would make more sense for him to seek revenge on the Blossom family in some way. We're also drawing a blank on why he'd go after Miss Grundy. Given his connection to the Blossom family, there's a possibility he's involved in the supply of jingle-jangle that's going around Riverdale but even so, would he really shoot two teens who are getting high?
