Warning: Stranger Things season 3 spoilers ahead.

With the fourth season of Netflix’s hit series Stranger Things officially confirmed, fans are (unsurprisingly) already coming up with some pretty detailed theories about what’s to come for the Hawkins gang.

One of the biggest questions viewers have is regarding the fate of David Harbour’s character, the beloved Jim Hopper. The third season concluded with him supposedly dying when he sacrificed himself to close the Upside Down—but after a confusing post-credits scene, nearly everyone is convinced he’s still alive. Now, people are posting tons of theories online as to how he’ll be making a comeback in season 4 (if he does at all).

The stars of Stranger Things have regularly been asked about Hopper’s fate, and although Eleven actress Millie Bobby Brown is remaining tight-lipped, she did just admit that the show's cast and creators are reading those fan theories. While speaking with Seventeen, the 15-year-old Emmy nominee was asked whether Hopper—her onscreen “dad”—would be alive next season, to which she replied, "I have no idea, but I love hearing everybody else's ideas and thoughts.”

“Ultimately," Brown added, "it’s nobody’s decision but the Duffer Brothers—you know, they’re writing it. I think the Duffer Brothers definitely feel the pressure of people's fan theories, though."

Brown is, of course, referring to Matt and Ross Duffer, the brothers who created the hit series. While the duo has yet to reveal anything about the the recently-announced fourth season, they better be prepared for plenty of questions about Jim Hopper. The fans need answers, and with no confirmed release date for the fourth season, we’re sure the brothers will be seeing a whole lot more theories in the coming months.
