A brief scene shows Tyler buying a gun from someone in an alleyway and later storing it in a hidden compartment in a trunk in his room that's stuffed with other weapons. It's a clear indication that the relentlessly bullied Tyler has a school shooting planned. During his admission to Hannah's parents about the tapes during his deposition, it looks like Tyler sheds some of the weight and guilt on his shoulders. Let's hope it's enough to keep him from doing something drastic or at least reach out for help.
