Kevin Porter: Clay... we don't know what was in her mind or in her heart. There's no way to know why she did what she did.

Clay Jensen: Actually, there is a way. Before she died... Hannah recorded 13 reasons why she killed herself. And you're number 13. And everyone who comes before you on these tapes knows what you did and didn't do. And they always will. And they'll know what they did. You're the last person to get the tapes. Hannah didn't leave any instructions on what happens after you... so you get to decide. And I added tape number 14... which I hope will help you make that decision.

Kevin Porter: How do you have these tapes?

Clay Jensen: I'm number 11.
