13 Reasons Why Season 2 Trailer Reveals That 'Hannah Wasn't The Only One'

13 Reasons Why season 2 swaps cassette tapes for mysterious polaroids, and promises that "Hannah wasn't the only one."

Ahead of the season 2 premiere of 13 Reasons Why on May 18, Netflix dropped the first official trailer for the new batch of episodes. The footage opens on Dylan Minnette's Clay Jensen, the introverted boy next door who fell for Katherine Langford's Hannah Baker and was, surprisingly, one of the reasons why she committed suicide at just 17 years old. Clay is seen opening his locker door, in which he finds a polaroid that teases Hannah's death isn't the only tragedy that will hit Liberty High. 

Though Hannah may be gone, she won't be forgotten. Actress Langford will remain a major part of the second season, and her on-screen mother, Kate Walsh's Olivia Baker, is set to team up with Clay to seek justice for Hannah's suicide. Clay's need to right the wrongs that led Hannah to take her own life pushes him to the brink, and it's revealed in the trailer that he now owns a gun.

The first season of 13 Reasons Why was divisive to say the least, with some feeling it offered a starting point for important conversations and others arguing it depicted suicide and sexual assault in a dangerous light. When Netflix announced that a second season was in the works, many believed it wasn't necessary. Series showrunner Brian Yorkey explained to Entertainment Weekly his decision to continue 13 Reasons Why: "We saw Hannah's version of events unfold, but there's a lot more to be told also about those characters. To me, there's a tremendous amount that I still want to know. I've said a few times that this show is about the way we raise boys up into men and the way we treat girls and women in our culture — and what we could do better in both cases."

He continued, "One way we'll explore that question is through the trial and also through all of these kids reflecting on where they are a few months down the road and what other secrets are being uncovered. That's going to take us into the past, into Hannah's story. We're going to get some new context for events we already know about and we're going to see a lot of things we hadn't even heard about yet that fill in some really interesting gaps in our understanding of who Hannah Baker was and what her life was ... We're going to continue to look very truthfully and very honestly at what they go through, even when it's painful at times. But I think what we're going to discover is, as they begin to emerge from this very dark time, there's hope and there is some light to be found."

More recently, Yorkey revealed how season 2 differs from season 1, stating that "in season 1, Hannah was telling us her story, we were experiencing it with Clay, and it was the central monolithic story of the season — her story, where it ended, and how that fell out in the present day." Season 2, on the other hand, is "very much more about everyone else's perspective on that story — their side of the story, their reaction to it, their coming to terms or refusing to come to terms with their role in Hannah's life and death."

Here's the official Netflix-issued synopsis for 13 Reasons Why season 2: "13 Reasons Why continues in the aftermath of Hannah's death and the start of our characters' complicated journeys toward healing and recovery. Liberty High prepares to go on trial, but someone will stop at nothing to keep the truth surrounding Hannah's death concealed. A series of ominous polaroids lead Clay and his classmates to uncover a sickening secret and a conspiracy to cover it up."

13 Reasons Why also stars Christian Navarro as Tony Padilla, Alisha Boe as Jessica Davis, Brandon Flynn as Justin Foley, Justin Prentice as Bryce Walker, Miles Heizer as Alex Standall, Ross Butler as Zach Dempsey, Devin Druid as Tyler Down, Amy Hargreaves as Lainie Jensen, Derek Luke as Kevin Porter, Ajiona Alexus as Sheri Holland, Michele Selene Ang as Courtney Crimsen, and Tommy Dorfman as Ryan Shave. Season 2 will introduce a total of 11 new characters and include trigger warnings ahead of each episode.

13 Reasons Why will return to Netflix for season 2 on May 18.
