We do wonder why Archie who is meant to be so central has been so removed from the mystery.
The theory continues...
"Why would Jason be tortured only to be killed and dumped in the river? I guess someone might have been trying to make him suffer, but then why decide to shoot him in the head? It seems more likely that they were trying to get information out of him. Maybe the reason they couldn't was because they got the wrong kid. When they finally realised it, they decided they had to kill Jason to keep him quiet."
Another use on the thread named Jordvnm added, "If [Grundy's] ex husband is as crazy as Grundy described him he'd kill him. The Blossom twins, Grundy, and Archie were all at the River at the same time, Grundy's ex husband follows Grundy and Archie there, but while trying to stay hidden, finds Jason (who yes, is a spitting image of Archie physically and characteristically) on the other side of the river, and kills him under the impression that it's Archie."
Although, that same user notes that the timeline doesn't add up with the way Jason was tortured.
"To torture someone you would have to be furious and personally offended, i.e. Grundy's ex-hubby. I don't know, the only thing this show is hanging off of at this point is who the killer is. We will see!"
