If you look into that hint it gives us a plausible motive. Let's say Jay was caught in the act of cheating by noon other than Hae Min Lee and she says she wants to tell Stephanie. Jay stated multiple times that Stephanie was his everything so Hae telling Stephanie about his cheating on her could end that relationship. Jay is also quoted saying he would do anything for Stephanie. So how far is he willing to go? Is murder included when he says “anything”or is there a grey area. Going back to his own observations these are what make him the most questionable, Jay remembers way too many details about how Hae looked. If Jay killed Hae that would explain his extensive knowledge on the smaller details of the murder and the changes in story. The things he is sharing could quite possible be his memories that he now has to use to frame someone else unfortunately Adnan being the easy escape-go. Jay killing Hae premeditatively makes more sense she had something that jeopardized Jay’s relationship with Stephanie so her panned out how to kill her and ended up being able to frame
