When a TV adaptation gets the multi-season treatment, it makes sense for new plots, characters and backstories to pop up. However, season one of Netflix's 13 Reasons Why stayed somewhat true to the novel of the same name by Jay Asher—that is, until the end. After listening to the tapes left behind by Hannah Baker, who died by suicide, book-Clay mailed them to the next person meant to listen and that's it, we never heard what happened next. On the show, Clay bypassed Bryce—a rapist in both versions—and handed the tapes over to the school counselor. Several new stories played out from there, and the season finale ended with Clay peacefully driving around with Tony and his childhood friend Skye, who, in the book, he doesn't reconnect with until the very end, once he realizes she's showing signs of being suicidal.
