Their story isn't over.
The TV phenomenon that is Selena Gomez's 13 Reasons Why gripped fans around the world when it launched on Netflix earlier this year.
A second season of 2017's most tweeted-about show is on the way, but what can you expect? From who's returning to plot details and fan theories, here's everything you need to know.
13 Reasons Why season 2 release date: When is it on Netflix?
Netflix officially announced a second season to air in 2018. Everybody from the cast to the author of the original novel Jay Asher was calling for it, so ultimately the renewal was no surprise.
Showrunner Brian Yorkey – who was behind season one – will be back at the helm, with 13 more hour-long episodes of the show in the works.
The official 13 Reasons Why Twitter account posted a short teaser trailer confirming season two, showing various memorable locations from the first season such as Liberty High School, The Crestmont, and Monet's.
The video on social media had the caption: "Their story isn't over."
Right now, there is no exact release date besides "2018".
On June 12, 2017, star Christian Navarro (who plays Tony Padilla) shared that the cast and crew were on set for the first day of filming for season two.
Season one launched on March 31, 2017, so Netflix may consider releasing season two at around the same date in 2018.
13 Reasons Why season 2 cast: Will Hannah be back?
Despite showrunner Yorkey playing around with the idea of making 13 Reasons Why an anthology series at one point – à la True Detective – season two will keep the same cast and the same setting.
Most notably, yes, Katherine Langford will be back as Hannah Baker.
"I think one of the things that is still hanging out there is this question of, is someone responsible for Hannah's death?" Yorkey said. "Is the school responsible? Who is responsible, if anyone is?
"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 also can't have a second season without Clay Jensen. Actor Dylan Minnette seems certain to continue on, as he shared this pretty cool Instagram snap:
Ross Butler (Zach Dempsey) confirmed his return, after he revealed that he dropped out of Riverdale to be part of the second season of 13 Reasons Why.
Christian Navarro (Tony Padilla) tweeted that he was back on set, while Kate Walsh (Olivia Baker) gave an interview confirming her character will play a part in the new episodes.
Brandon Flynn (Justin Foley) said he was excited for season two, posting on Instagram: "Can't wait to get back to work with this beautiful team!"
Alisha Boe (Jessica Davis) and Justin Prentice (Bryce Walker) also seem certain to come back, with Yorkey stating his interest in continuing their stories (more on that later), while Miles Heizer (Alex Standall) suggested his cliffhanger will be addressed – meaning he will return in some form.
Michele Selene Ang (Courtney Crimsen) said on Instagram: "See all you freaks back at Liberty High."
13 Reasons Why season 2 spoilers: What will happen?
Firstly, the tapes are being scrapped. Those cassettes still exist, of course, but rather the episodes will no longer be structured around Hannah's narration.
Instead, there will be a "different sort of analogue technology that plays a hugely important role in season two", showrunner Yorkey teased.
"The cassette tapes aren't at the centre of it – those two boxes of tapes are still hanging around and matter to people, but there will be a new piece of technology for 13-year-olds to Google and try to understand what it was."
Season two will keep the multiple-timeline storytelling, but Hannah is no longer the narrator. Instead, somebody else will be providing the voiceover.
We will see "other perspectives on Hannah's story", too. This is particularly interesting, because there were a couple of moments in the first season where certain characters questioned Hannah's "truth".
Of note, remember the letter that Hannah gave to Zach? The one which she claimed he had thrown away, thus rejecting her plea for help?
The reality is that Zach actually kept the note. Did Hannah lie, or was she just mistaken? Maybe that will be explained.
Lastly, a lot of fans seem to think that Tony is either a ghost or a figment of Clay's imagination.
This one is a little more difficult to swallow, mainly because we have seen Tony interacting with plenty of other characters besides Clay, but it's interesting nonetheless...
