In the last chapter, we are told that Alex shot himself in the head, he’s at the hospital, it took all of us by surprise! But that’s exactly how they wanted us to feel. Surprised.
Why? Everyone who sees suicide from the outside thinks you can get signs from people who are about to do it, they are trying to make us understand that it is not that easy to catch those signs.
Let me explain… before Hannah died she had problems talking to her parents about personal stuff, her emotions and Alex can’t talk to his dad because they have different point of views, he doesn’t trust his father, he even calls him sir.
Before Hannah died, she ordered her room, the last scene where you see Alex is when he’s in his room cleaning up, and it is the first time he calls his father “dad”.
When they said “17 year old guy shoot him self” we thought about Justin and Tyler who recently got guns… but Alex’s dad is a cop. Alex had a gun.
Although I’ve seen some other theories that actually make sense, this is mine, this is what I think happened. Xoxo SB.
