After recently releasing a teaser trailer, the streamer has dropped a full-length Season 2 trailer ahead of the controversial teen drama arriving back on our screens later this month. And true to form it raises so many questions, like what do all the polaroid photos mean?

If you haven't watched the first season yet, here's a quick recap: after high school girl, Hannah Baker (played by Katherine Langford) takes her own life, a series of cassette tapes are given to Hannah's friend Clay Jensen (played Dylan Minnette). On the tapes, Hannah gives reasons why she made the devastating decision to end her life. The reasons include various horrible things other students at their high school said or did to her and Clay is left trying to figure out what really happened.

But the first season didn't really end with conclusive answers, it left fans of the show wanting more Hannah (who appears regularly to Clay in flashbacks or during scenes from the tapes), more Clay and more reasons.

So even though the tapes are done, the story isn't. The new trailer for Season 2 opens with Clay walking the school halls saying, "I thought this whole thing would be over, but it's not." He opens his locker and a polaroid falls out which says, "Hannah wasn't the only one."
