And she claims that her goal, once she realized Allison was never going to admit the truth, was to frame Allison for the murders, but we never see any evidence that might lead anyone to suspect Allison. Why allow him to live? Not to mention that Margot loved Johnny and had no attachment at all to Dylan, so it's bizarre that she'd kill her best friend instead of the guy she barely tolerates. She says she killed Johnny because Allison loved him most, but everyone knew that Allison was hung up on Dylan. But it doesn't actually make sense in the context of what we know about Margot and Allison. Margot tells Allison that her goal in killing half of Wai Huna was to force her to admit the truth, that Lennon was dead and that she, Allison, had assumed her identity. While it was absolutely the right call to go with an established character as the killer, 'I Know What You Did Last Summer' completely drops the ball in trying to explain why she did it. Riley winds up having more lives than a cat, yet none of the big reveals that she's inexplicably still alive wind up being witnessed by anyone or having any impact whatsoever on the story. Bruce used to be married to Clara, who was in the cult, and witnessed the teens hiding Lennon's body, but then Clara dies and none of it matters. There is an extended subplot about Allison and Lennon's father Bruce (Bill Heck) carrying on a not-so-secret romance with Sheriff Lyla (Fiona Rene), yet they end the series more or less in the same place they started.

only for none of that to really be particularly relevant or explained. The first episode introduces us to a mysterious cult whose members all killed themselves years earlier, and subsequent episodes reveal that familiar members of the community are actually still involved in the cult themselves. Unfortunately, while the expanded cast makes plenty of room for red herrings and surprise reveals, it also opens the door for countless subplots that never get much room to breathe and don't really lead anywhere.
