Chapter 14: A Kiss Before Dying

Theory: Grundy's ex is the killer

I think it was grundys ex that tried to kill fred, because she mentioned he was abusive to the extent that she had to leave and change her name. So he’s probably getting revenge because he’s jealous of all grundys affairs with students. We dont know if this was his first attempt to kill someone or that archie was grundy's first student affair. The killer he attempts to kill fred to get back at archie, and then kills grundy because hes mad at her for leaving him and having these affairs. It couldn't have been a coincidence that she was saying goodbye to a "student" when she was killed. There are a lot of holes in this theory, but the season has only just started.
