It sounds vaguely plausible at first, especially now that we’ve witnessed the reintroduction of Eight, but as people started to take the theory apart, they found flaws in the logic. As one commenter pointed out, “the d20 doesn’t get rolled for damaging hit points, it gets rolled for checking if an attack hits or not…” and the consensus was ultimately that the theory fundamentally misunderstands the rules of D&D. It’s still a fun one, but probably a bit of a reach.
Vecna is Creating a Wormhole to Time Travel
This is the dominant theory going into the next batch of season 5’s episodes.
We’ve already seen Hawkins’ science teacher, Mr. Clarke, explaining the concept of wormholes, telling the kids that wormholes could theoretically facilitate travel across massive distances, dimensions, or even through time itself. On his chalkboard, we also see that a similar hourglass/tunnel-shaped sketch that Will Byers drew based on his Vecna visions.
In season 5 so far, Vecna is targeting 12 children for capture, who some people say represent the “anchor point” hours on a clock (clocks being a common Vecna motif), and that he will use the kids as a kind of human clock to open a wormhole and rewrite time. Some also posit that the impenetrable wall we saw in season 5 is a circle with points laid out like a clock.
Though this theory is unsubstantiated, a big chunk of the Stranger Things fandom is pretty convinced that we will see Vecna or the gang have to rewrite or reset history to save the day. Robin’s joke about Back to the Future’s flux capacitor MacGuffin in season 5 has only added fuel to the fire.
Hopper Will Propose to Joyce Using Jonathan’s Ring
In a twist based on emotional stakes rather than timey-wimey plot machinations, some fans think that the engagement ring given to Jonathan isn’t for him to propose to Nancy, but for Hopper to propose to Joyce. This is based on repeated references to the number 37 showing up in various romantic scenes between Hopper and Joyce (“Jopper”, if you’re shipping).
