Everyone's talking about 13 Reasons Why, a 13-episode Netflix series based on Jay Asher's book with the same name. The series follows teenager Clay Jensen in his quest to uncover the story behind his classmate Hannah's decision to end her life.
Warning: spoilers ahead.
We found out during the last moments of the final episode that the 17-year-old who was rushed to the hospital after suffering a gunshot wound to the head (episode 12) was Alex. The wound was reportedly self-inflicted; however, one fan theory suggests Tyler, Hannah's stalker and Liberty High's bullied photographer, shot Alex.
