Stranger Things has no shortage of tragedy, with a boy's mysterious disappearance kicking off a series of terrifying and supernatural events in the small town of Hawkins, Indiana. The Duffer Brothers' hit Netflix show stars a cantankerous but noble police chief named Hopper (David Harbour), who joins forces with the boy's distraught mother Joyce (Winona Ryder) to investigate the matter and push back the dark force at play. But the sheriff's own tragic past also has a lot to do with his current mission, and a new interview with Harbour suggests that Hopper's daughter might be integral to his figurative reemergence in Season 2.

As fans will recall from the show's first season, Hopper's young daughter Sara died from cancer at a young age. The loss of her prompted him to turn to alcohol and a hedonistic lifestyle, which ultimately drove him to return to his hometown in Hawkins.

But what exactly happened to his daughter in the years leading up to her death? Reddit user keulenshwinger points out that in a scene from season one, Sara can be seen wearing a blue hair tie. And if you look closely at the shot, she's holding a stuffed animal that looks eerily similar to Eleven's.

In a recent interview with TV Guide, Harbour seems to confirm that Sara will indeed be a major player in Season 2, though he's tight-lipped about the specifics. He says that Hopper's understanding of his relationship with Sara will be "a much bigger focus in Season 2," but he's not giving away any further details about what to expect from the episode.
