Spoilers follow for the first four episodes of Stranger Things Season 5, “Chapter One: The Crawl,” “Chapter Two: The Vanishing of Holly Wheeler,” “Chapter Three: The Turnbow Trap,” and “Chapter Four: Sorcerer.”

By the end of Stranger Things Season 5, Volume 1, the Hawkins campaign against Vecna (Jamie Campbell Bower) is most certainly game on. Will Byer’s (Noah Schnapp) throwdown of Vecna’s Demogorgons seemingly positions him as the Dungeon Master extraordinaire. But there’s still so much that the Hawkins party doesn’t know about their adversary’s endgame, including everything at his disposal to ensure he achieves the horrific vision of Hawkins that he shared with Nancy (Natalia Dyer) in Season 4.

As always, every new batch of Stranger Things episodes opens the door for new questions, and that’s certainly the case again at the conclusion of the first four episodes of Season 5. As we’re still processing the insanity of that cliffhanger, here are a few burning questions we’ll be pondering until the next three episodes arrive on December 25, 2025.

What Is Dr. Kay’s Overall Mission?

The Duffers love their ’80s-era iconic actors. They’ve cast quite a few in some juicy parts across the seasons, including Matthew Modine as Dr. Martin Brenner, Sean Astin as Bob Newby, Paul Reiser as Sam Owens, Cary Elwes as Larry Kline and Robert Englund as Victor Creel. In Season 5, Linda Hamilton joins their esteemed, nostalgic company as the enigmatic Dr. Kay.

In the first four episodes, all we know about Kay is that she has her own well-funded and well-protected lab in the Upside Down. She’s not exactly warm with her subordinates, and is more in keeping with the behavior of Bishop the android (Lance Henriksen) from Aliens when it comes to their shared intensity regarding alien creature vivisection. But her acquired knowledge seems to have given her control of some of the critters, like the one that chokes out Hopper.

By the end of Chapter 4, we do know that she’s somehow found and forcibly taken Eleven’s (Millie Bobby Brown) fellow lab sister Eight, a.k.a. Kali (Linnea Berthelsen). We can assume that the same sound device Kay uses to immobilize Eleven also works, or worked, on Eight. Now she’s harnessing Eight’s powers in some kind of machine, but how? As a reminder, Eight can manipulate and project illusions into the minds of those around her, which begs the question: Is what Eleven and Hopper see in the lab real, or is Kali projecting whatever Kay tells her to? It’s too early to tell if Kay is a nefarious player in the military’s research or a sympathetic scientist when it comes to all things in the Upside Down.

How Did Kali/Eight Wind Up in the Upside Down?

As alluded to above, Kali Prasad/Eight was one of Dr. Brenner’s lab children that he conducted experiments on starting in 1979. Prior to One/Henry Creel/Vecna killing all of the children in the lab except Eleven, Eight had escaped the lab and collected her own family of misfit runaways in Chicago. In Season 2, Eleven seeks out the girl who escaped and they bond over their shared experiences and special powers. They part ways that same season and haven’t reconnected until Eleven finds Eight in Dr. Kay’s Upside Down lab machine. We have to imagine that she was never really as off the grid as she imagined, between Brenner’s files and perhaps even the tracking of Eight after her escape. And when Kay needed to bring Eleven into her Upside Down lab, the best bait would be Eight.

Will the Wheelers Survive?

Karen Wheeler (Cara Buono) and Ted Wheeler (Joe Chrest) got shredded as they attempted to protect their youngest, Holly (Nell Fisher), from that rampaging Demogorgon in their house. They were both slashed up so brutally that we actually felt a teensy bit bad for Ted, who has been consistently inert as a father and partner across all five seasons. The pair were both alive when they arrived at the local hospital, and Karen even was conscious enough to identify Holly’s “imaginary friend” as Henry. That said, we wouldn’t be surprised if one, or both, were sacrificed to the stakes of this finale season. On the other hand, we also wouldn’t complain if Karen survives and gets to escape the purgatory that is Hawkins suburbia.

When Is Steve Going to Call Dustin on His Shit?

As Steven Harrington (Joe Keery) has evolved from lunkhead high school jock to emotionally perceptive adopted dad of the Hawkins misfits, the writers have recognized that he’s their secret weapon for great character moments. He gets to land some truth bombs on Jonathan Byers (Charlie Heaton) in this block of episodes, but we’re really waiting for an overdue thrown down between him and bestie Dustin Henderson (Gaten Matarazzo). The typically enthusiastic science nerd hasn’t processed Eddie Munson’s (Joseph Quinn) death from last season at all, and it’s turned Steve’s little bro into an angry, bitter shadow of his former self. In turn, their bromance plays out more like a troubled marriage in these first episodes as they snipe and bicker at one another. We know it’s just a matter of time before Steve gets to the bottom of what’s going on with Dustin and when it happens, we don’t expect to survive it without some ugly sobbing.

Is the Organic Wall Connected to Vecna’s Evolved Look?

The organic matter that energizes Vecna in the attic of the Creel home has been an evolving organism ever since we first got a good look at it in the Upside Down in Season 1. We’ve seen those tendrils attach to Vecna and replenish him during his regeneration time. And then he seemed to use them to bind and contain his victims in the Upside Down version of the Creel house. But what they are and if they’re autonomous from Vecna remains a mystery.

In Season 5, the massive organic wall discovered by Hopper and Eleven in the Upside Down is reminiscent of the wall that Vecna attaches Will to in the season’s first episode, just writ large. Is the size of it now indicative of Vecna’s power? When he appears through the portal into Hawkins in "Chapter Four: Sorcerer,” Vecna looks different. His once humanoid-looking right arm is no more and matches his entire body in appearing more thorny, with active movement slithering across his form. He’s jacked too now, so maybe the size of that wall is directly connected to this more ‘roidy-looking Vecna. Is there a way to damage what the wall parallels in the Rightside Up in order to weaken the demon?

If Max Is Revived From Her Coma, Will She Be Changed Irrevocably?

For 584 days, Max (Sadie Sink) has been roaming inside Henry Creel's memories. Even though she’s found a safe space inside the rock cave — a place Henry won’t enter — the question remains: What will the cost be for Max to spend so much time trapped inside that monster’s head? Even if Holly is the key to Max’s escape from the cave and the coma, will she be irrevocably changed for the worse? The best case scenario is that her time in Henry’s head will help the gang figure out how to take the villain down. Maybe she can look to Will’s burst of power to figure how to harness what she’s learned from Henry’s memories to use them against him?

How Does Will Pull Off an Eleven Power Move — Bloody Nose and All — at the End of Episode 4?

The prologue of "Chapter One: The Crawl" makes it very clear that from the moment Will Byers was yoinked into the Upside Down, his connection with Vecna has been physical, intentional and part of a long game. It was wild to see tiny, vulnerable Will encased in organic matter and forcibly face-hugged by Vecna as he did who knows what to the kid. But it certainly confirms that every Will neck tingle, every phantom feeling, every barfed-up slug has been strengthening whatever Vecna initiated between them. What we don’t know is if Will’s Eleven-style power move at the end of "Chapter Four: Sorcerer" was always part of Vecna’s plan, or if Will’s increasing confidence paired with his love for his family and friends manifested in his siphoning of Vecna’s power, which facilitated that Demogorgon massacre? Either is interesting, but the latter is a twist that could finally tilt the power tables against Vecna.
