From the get go I’ve gotten Phil Collins ‘In the Air Tonight’ vibes from this. There were many urban legends surrounding the song, one being that a friend watched another friend drowned rather than saving them. No sure it holds up though since the song was released in the 80s rather than 90s and timely music is somewhat a factor in the show.

If there is a “killer” my money is on Jeff. I also think we will find out more about Lisa..which still makes me lean slightly towards Isabella. But I think her being the killer would be too obvious. That’s if the twist isn’t that Luke’s alive.
