okay but what if the pictures in the dark room were all of tyler’s possible targets. it’s clear that toward the end of the series Tyler is being pushed toward violence and anger. On top of bullying the came along with clay’s picture he is also being pushed around by Monty. this could possibly be why alex’s picture is torn down because we see him in the ambulance before it is confirmed who it is. that’s why the head wound left alex alive but in critical condition, because he didn’t do it himself. the odds of someone surviving a self-inflicted gunshot to the head are usually unlikely. plus after we see the ambulance we see tyler stashing away his guns probably after fleeing his crime scene as he has gotten good at stalking. he is probably planning on targeting the school and everyone mentioned on the tapes. BUT LIKE THATS JUST MY THEORY IDK I JUST KINDA HOPE THERES A SECOND SEASON. I LIKE THE SHOW AS A STAND ALONE AND THOUGH ITS VERY CLOSE TO THE BOOK AND I LIKE WHEN THINGS STAY ACCURATE ID REALLY LIKE A CONTINUATION
