Max surviving has got to play a role somehow. Based off how when she was in Lucas’s arms while in the attic her eyes were still cloudy (I’m pretty sure she even said “I can’t see”) I’m assuming she has permanently lost her eyesight and now will be some kind of “seer” she’ll be connected to Vecna in a similar way to Will. Will can feel what Vecna feels and Max can see what Vecna sees. I don’t know it’s just a thought based on her injuries. I don’t know anything about D&D so I could be way off base.

Will Byers being a connection to the realm and the mind flayer makes sense. I did have a feeling that Vecna has been preparing Will since around season 1 to be his vessel if things turned sideways. But if that is the case, wouldn't that make Will the actual heart of the group? I would say that Mike is the inspiring leader, but definitely not the heart. Can't wait to see the finale of Stranger Things!

To be honest, I cried waterfalls when Eddie died specially on what Justin said to Eddies Uncle "He saved the town that hated him"

Everyone keeps ignoring Kali's role. She was teased in the first episode of season 4 with papa's crossword puzzle, she made people see creepy psychic spider's just like Vecna, she gave 11 the same advice about tapping into a painful memory to unlock 11's full potential, and she's on her own bloody quest to return order and balance to the world. I see her joining Vecna in season 5, betraying him, and being killed in turn. I didn't know abot the Kas connection before, but Kali might take the role of Kas.

that pop up shop in Paris was actually pretty cool, was lucky enough to go last month

matpat actually was really close to the actual lore in his first stranger things theory. although when st2 came out a lot of people were commenting how it was completely off but as we went further into the seasons and got more info, it turned out that matt was right all along

I have a theory that Vecna's horcrux (can't remember the name of the D & D version) is going to be the clock. The clock has often and/or always appeared in victim's visions, and they include a specific scene of Nancy seeing him rewind the clock. The reason everyone sees the clock might be because when Vecna takes over their body, they are a part of his mind. (Also side note, I think when Chrissy sees spiders crawling out of the clock it's an analogy for the four gates and the Upside Down.)

As for the theory about Vecna killed the eight, it works out. Vecna was one and eleven was, well…Eleven. And we also have to remember that the one girl escaped when she was little and joined a “gang”. So, all of the other telepathic kids represent the eight

If Will has gone through everything he’s gone through and sacrificing his love life for people he loves and then has to sacrifice himself physically before ever getting the happiness he deserves, I think a large portion of the fandom will riot. He has been unnecessarily to a degree tormented in this show. It’s not even like Eleven where she has been fulfilled in some portions of her life since the show has been going on.

The Duffer Bros said a lot of S5 would be similar to how things were in S1. And that worries me. Because at the end of S1, El ended up sacrificing herself to save everyone else. I do think Will and El taking down Vecna would be a really satisfying conclusion considering he's been tormenting the two of them since the show started. And Will and Henry both are described as sensitive kids with a knack for art. So I definitely think there's more to their dynamic.

I think Will is going to have a Harry Potter arc where he “dies,” but comes back to defeat Vecna.

Genuine question here: am I being silly by immediately thinking the theory was going to say that the Grandfather Clock was going to be a Phylactery when MattPatt introduced them? He was going down the path of saying it was obvious and I was going "yup, that big clock as it tolls whenever he captures someone so is prevalent in hospital existence." and then he goes onto Will.....I mean, yeah, sure he is a clear one also, but I 100% thought it was going to be the clock.

Vecna actually has even more foreshadowing in season 1. The most damning moment to me is how Brenner says, that the Demogorgon wants to contact El, because it “wants her”, as Martin says. We know, that the Demogorgon has the consciousness of Vecna inside of him, so this shows that Vecna wants to contact El specifically, not any other human. This means that they already had in mind the story of the main villain knowing El (because they were both test subjects)

I feel like Eleven's sister will really come in handy in season 5, I mean they really left us off in a cliffhanger when Eleven decided to split with her last second. I also remember she showed her that she can make things appear when their really not there so I feel like that ablititly itself will really help Eleven in what she needs to do

I'm surprised so many people disliked the way Eddie died. I thought it was very sentimental and gave an already tragic character a phenomenal ending that still lingers in my mind. Don't get me wrong, I really liked Eddie. But I don't think he would have made such a huge impression on me if it wasn't for his last words or the fact that, despite everything that went down, he still wasn't vindicated in the real world. Sometimes characters don't need a "happily ever after" ending to shine through.

I think the three-year gap was the reason why Stranger Things S4 did so well. We were waiting for so long, and they knew exactly how to hype up each season, then they did another smart thing by releasing it into 2 parts. Just over a span of a month so people wouldn't forget, and it made people discuss and make theories. This not only brought in more people but it made even more hype

Petition for Mat to make ‘predicting the ending’ an actual series on the channel for all sorts of shows

I'm with you on Eddie. His death was easily the dumbest part of the season.

How does nobody realize that *Billy* might end up being Kas? Dude was the first one Vecna targeted when developing his plan. It was Billy that was being talked to, and it was Billy that gathered people to make the mind Flayer in the world. *And if nobody truly dies and instead lives in Vecnas mind, then THAT would give Max even MORE of a purpose and connection to Vecna by connecting to what is left of Billy.* They even brought him back for an entirely NEW scene in season 4. If they hadn't had any plans for him in the future, then they'd just have max remember him by using previous footage. Max being blind could also make her have a connection with him.

my conspiracy theory: The Mind Flayer is Kas and Will is going to fill the role of the sentient sword. in the lore, its the Sword of Kas that corrupts kas into betraying vecna. In previous seasons its been shown that will is an important counterpart to the mind flayer with his connection to the upside down and for a time the flayer himself. I think in season 5 will is going to use that connection to ally with the mind flayer against vecna somehow.

I have this feeling Will is going to have his Harry Potter moment, since season one the news clipping at the end of the season “the boy who survived” has always sat with me… i think he’s going to sacrifice himself for everyone to destroy vecna and i’m not sure if he’ll come back from that

There is one person we are not taking into consideration as Kas: Max. The former best friend now brought back to life by Vecna as a sick joke against Eleven which then backfires might be a really compelling arc. We also do not see Max when El tries to go search for her at the end of the season which has me believing Max is taken by Vecna. That ending scene has to mean something. So this is my theory.

The clock sounds were added to the old episodes just before season 4 was released. They weren't there at the time of their debut. The creators had talked about going back and adding some details to old episodes.

“Just like Eddie uses against the dema-bats during the final battle” *camera pans over Eddie holding a spear*

Fun fact: The Shadowfell was actually named the Veil of Shadows in advanced d&d and was referenced in season 1 to describe the upside-down.

Honestly, I think that Max will will have to die. She says herself "I'm still connected to Vecna. I'm still marked." So if Will has to die because he's connected to Vecna, wouldn't Max have to die aswell? But permanently this time.

16:14 so Will is kinda like Harry Potter. He's the boy who lived, and he still has a connection to Vecna (like Harry to Voldemort)

Yooooo I got chills when you discussed will being a part of the hive mind. I think you nailed it. This final season is gonna rip my heart out.

As much as I love Eddie, bringing him back I feel will cheapen his emotional death scene and his uncle’s and Dustin’s loss. Makers can’t also bring characters back just coz fans want them back, even in a fantasy dynamic. I do however agree in the belief Will is going to be either be the big unwitting baddie of the final season or the sacrificial hero, either way he’s gotta be saved with mental consequences or mercy killed to claim peace for both him and Hawkins..

I really really hope Will doesn’t die, he’s been through too much :( Also, as who the “Kas” will be, I feel like it will be Will, since he’s somewhat with Vecna. It would be great to give the usual victim the chance to be there rescuer.

Honestly, I kinda think Eddie's death might have been so shoehorned in because they were set on him being Kas and choosing a song that could symbolise that turning well after his confirmed death kind of makes it even more compelling for me, as if they were really trying to justify his forced death. However, I really dislike how often they bring back characters so I'm kind of hoping this theory about Eleven is correct.

5:19 Eddie had to die because when the demmobats saw that it was a recording, they would go directly back to the mansion. Ergo Eddie had a resin to die

I would like for Mike to take a bigger role in season 5. Since Season 2 he’s been kinda sidelined. I think max might also be connected. Maybe she is in a coma connected to a hive mind. Maybe that’s what rips the original boys. Mike and will die and Lucas is heartbroken. Maybe their familys die or Dustin loses steve. The loses could bring Nancy and Jonathan together too

Theory: One phylactery could be the clock, as it has so much significance but could be easily overlooked as a common item

This theory is so tragic, and it’s so depressing, but it’s brilliant. Though it would be heart wrenching to watch something like this go down and watch Stranger Things come to an end like that, it would probably be one of the best endings to a show ever, if written well and done right. I mean, I hate to say it because I don’t want to see my favorite characters die off like that, but it would be an insane ending to this story.

I figured the phylactery was the grandfather clock from his childhood that lurks in every nightmare. The hive mind connection with will may be separate from the phylactery, or the hypnotic effect of its pendulum may be an integral part of establishing his connection.

I (along with MANY other people) feel like Will needs to play a big role in the next season. If he did die it would be very tragic (aT LeAsT hE cOuLd mEeT eDdIE) but could be a way that would fit the story. However, I feel like Will and Max could be candidates to be Kos if Netflix doesn't want to end their storyline tragically with a barricade of emotionally distraught fans. I also feel like Dustin and Steve have a strong connection point for the group. Great theory as always!!

Honestly they should've saved off Eddie's death for Season 5, that way they could find a more useful death and given us some more time to build his character and make a death more impactful.

I think it's important to point out that party level and growth in D&D can be EITHER XP based OR Milestone based (gaining levels based on achievements or completing quests). So even if we won't get an exact theory calculating party levels, it's easy to say that everyone who's still with the group has to be rocking some pretty high levels with everything they've done!

eddies guitar solo in master of puppets was amazing, #justiceforeddie

I think the mason jar with the dead spider in it is a great candidate for Vecna's phylactery, as it predates Will entering the upsidedown, and it seems to have held some special significance when its found.

I’m just hoping they do more with Will. Since the 2nd season with everything that started happening to Will after he escaped the upside down, I’ve been hoping he would get powers or be the hero. I mean come on, out of everyone that got sucked into the upside down in season one, he was the only one to somehow survive. He even survived being possessed in season 2 by the mindflayer. I know they’ve put a lot of emphasis on Eleven being the hero, but have the secret weapon in the background; its Will, it has to be! When they play DnD, he is the cleric…I don’t know much about that game, but from what I looked up, this is the description of that role: “Clerics are skilled in the use of divine magic. Clerics are powerful healers due to the large number of healing and curative magics available to them. With divinely-granted abilities over life or death, they are also able to repel or control undead creatures. Clerics also have specific 'domains' which usually align with the character's alignment... Whether the cleric repels or controls undead is dependent on the cleric's alignment.” I think *alignment* being the key here. He’s been in the back of the team so far. In season 3 & 4 they made Will seem kind of weak emotionally with him being sad about his friends not playing with him, everyone getting into relationships except him, and his feelings for Mike. Even that painting he made for Mike, he put himself way off into the backline of the depicted fight. Maybe the show writers did that on purpose to make Will seem like an unlikely choice to essentially “win the game” for everyone. With DnD being the theme of the show and how much emphasis they’ve put on that game (his disappearance was even told/predicted by the game in the first episode) , it only makes sense for him to finally be put in the frontline and use his power to somehow control and defeat Vecna. The show started with Will being the first one to be targeted by Vecna, so it needs to end with Will fighting him. Those are my thoughts anyway.

really mat! netflix has to change their script now.

I think you’re right up until Will’s death. I think it’s gonna be a struggle when they find out Will needs to die but when Mike gets killed Will and El will have a conversation where Will confesses his love for Mike and then decides to sacrifice himself to take down Vecna and avenge Mike.

My favorite moment in the show was when Vecna said: "Its Vecnin Time" then Vecna'd all over the place. Truly some stranger things. Ty for the likes

I think the more important link between Eddie and Kas is that Kas is known for his signature spike-laden shield which Eddie uses. Not his sword

The song choice used for Eddies death scene would lead me to believe he's still alive, the show has used the song b4 in scenes where we think someone is dead but they come back to life (season 1 episode 8 - 37:40 ish area) They did this again with another song, Peter Gabriel's Heros. Used when they find Wills fake body in season 1 and again at the end of season 3 when we think Hopp is dead. To me it looks like music plays a large part in the show, both the above songs repeated on the show, and the connection to should i stay or should i go" and "running up that hill"

I still feel like they're saving 8 to bring her back for a big revelation. Since 5 is going to be their last season I think it's going to be her year but that's just me

I’m gonna be sad when Stranger Things ends. It’s such a good show and we’ll thought out. I love all the characters and don’t want anyone to die. Especially STEVE!!

I agree so hard with the pointlessness of Eddie's death. Half the characters carry portable tape players like a Walkman. They could have rigged that to the guitar amp easy peasy and pushed play and walked away...

I’m so excited for the new season! And the ending is not so predictable but your theory always makes me so interested on it.

Someone else in the comments talks about this a little more but I think Max is gonna be able to see what Vecna sees kinda like how Will can feel what Vecna feels. It would make sense because of how after the mind flayer left Wills body he got his "true sight" ability.

I feel like they've been setting will up to die sense season 4. They made him more relatable, racked up the sympathy for him, all to drive him tword a very emotional death after he finally figures himself out like we've all been hoping.

if stranger things does follow this theme, one of vecna's phylacteries could be the clock as he uses it so much throught the entire show, e.g. when hopper is in the tunnels, when will falls off his bike, when max sees the clock. the clock is used to much that it will definitely be used in season 5.

I think the clock noise before will gets trapped in the upside down is his bike wheel turning

there's dis whole theory that Kali's acc gnna come back and it's been teased at the start of s4. Not only the crossword puzzle being a part of it but in the beginning, while they were playing dnd, rolling an 11 wasn't enough to defeat Vecna and during dis Lucas, who is no.8 (Kali was also no.8) was needed to win the basketball game. So it seems pretty full circle and foreshadowed.

Steve better get a good ending, he hasn’t had a real big win in the entire show. He deserves it

Great theory, but on Eddie's death feeling pointless, I feel like everyone forgets that the bats could've followed him through the portal, and if they didn't, they could've gone for the gang at the house so, it's a sad death but ultimately its not pointless

Maybe 11 should go inside Will’s mind to find the Vecna as he still is connected to Will and also find out that Will has feelings for Mike

He predicted GOT ending in 2016, the man is a prophet. The algorithm is indeed weird because it recommended me that video in 2022. I'm taking his stuff seriously now.

The last episode which was 2 hours and 22 minutes long is better than most of today’s movies with the same runtime. Not one second I was bored. The creators of this show deserve an Emmy.

i feel like Matt is completely wrong here, i think stranger things' Kas might just be Will, why do i think this? 1.Will definetely is building up to be important in season 5, Max style 2. His connection to Venca and the upside down may lead to Vecna wanting to partner up with him in some way (i think it might be a thing of him manipulating Will) 3. Will has been through a lot, which might make him vurnerable enough to help Vecna in some way. But in the end he will betray Vecna and save the day

Please do another one of these I’ve been waiting for so long

I’ve thought that it was gonna be either Billy or Eddie, since the end of last season. But apparently Eddie is coming back the next season, so at least I’m happy about that, he was literally my favorite character.

Theory: Karen’s (Mike’s and Nancy’s mom) stranger things 4 poster also has Vecna’s house in it. Plus she’s the only side character that has a poster, she’s also the only parent that has been showed a lot more than the other ones (besides Joyce). Maybe she might play an important role too? And Nancy also said that she saw her in the vision. Idk just a theory 🤷‍♀️

Steve needs a win man. He’s my favorite character and the past few seasons he’s been getting knocked down time after time. My friend didn’t believe me until he saw the ending.

Could Kas be Will? Someone that Vecna has used in the past? It could be a cool arc to see Will finally triumph over Vecna, who’s been manipulating him throughout the seasons

We can also assume that when Max said she can’t see or feel anything Vecna tried to reference a hand and an eye. Something I wanted to point out I didn’t see in the video

These are my points/thoughts for S5. 1. The deaths from past characters lingers and are actually useful to our heroes, but to Vecna as well. Dustin just joined the "Vecna messing with your head" club with Eddie. Like Nancy and Barb or Max and Billy. 2. The show already hinted at the parents getting involved and don't forget the world is still after our kids, and considering Hawkins is about to become an apocalyptic place, The parents will have to step up and protect their families. Based on the interaction with all of them together, Mike's mom seemed to be the "leader" worthy person of that group followed by Lucas' mom? 3. I always thought either Hopper or Mike would die bc they're the 2 most important people to El. She needs a boost to fight Vecna if you will, just like how 8 trained her. 4. We still don't know what other powers El is capable of as she did do something to Max at the list minutes to "save her". 5. I think the bats will have an effect on Steve, bc Robin might have foreshadowed rabies with bats. 6. I still think the therapist is sus bc of her necklace being a key, and the keyhole on the clock. Maybe the clock is an item or the house? 7. What happened to Murray and Enzo? We didn't see them, but I'm assuming Murray is hiding him and let's not forget the Russian gov and our gov still hunting El and Hopper or the traitors. 8. 8, that's right. I hope she comes back to help or even bring back up. 9. There's going to be a lot of mind tricks, "Will" duplicates or soldiers. 10. I don't want anyone to die, but there's probably going to be pre deaths, followed by final moment deaths. 11. I DEMAND JUSTICE FOR WILL. LEAVE HIM! I also hope Mike changes bc I don't care if he dies bc he's such an idiot and a jerk rn, but I don't want El to hurt again lol. Gosh I hope it ain't gonna be Hopper or Dustin or Steve. They're like my top 3, followed by El and Max and Joyce and Will for 4th place

I theorize that Max will gain powers due to some of that classic 80s "power of love" cliche. We see how Eleven is saved from One as a child by her remembering her mother's love. Defeating him gave her increased power. Since we see Max somewhat saved by El's love, but left blinded, it is possible part of Vecna lives in her now and she will gain powers.

As a Long-Term GM, did you consider Module Completion Experience when estimating Levels? Each Character gains an amount of EXP determined by length and difficulty of the module, as well as Equivalent Party Level. (The Key being that there are 2-3 Active Parties at any given time during Stranger Things). Would love to see your opinion on Levels using your equations plus like 1,500-2,000xLevel EXP per Character per Module/Season.

Adding on to the death of the 8 sorcerers when Vecna showed up in DND, he killed 8 of the other psychic children. He killed all but himself, #8 and 11. Just adding on to Matt’s already amazing look into this.

My theory is: Nancy mentioned monsters, army from what she saw. That has to mean new beasts, right? One of them has to be Borys. The three-headed dragon. 2. I feel like that the mind flayer will return in season 5. Some posters showed the mind flayer and the dark clouds might even feuture it. 3. Max will possibly wake up from coma/vecna’s mind in the end or in season 5 4. The ending shows us that there is the last vines from upside down or there is a hidden gate.

Never once did I think I’d hear the name critical role in a film theory video

I loved hearing you mention Critical Role! I wish we could get a theory on campaign 3, it is such a wild ride so far, but man what a time sink x3

You know what would've been fun for the community? If they released the episodes weekly. So that every week all the fans could talk and speculate about all the different theories they have running in their heads. Like legit speculate about the questions that continue to arise as they watch it episode by episode. Lots of people get it wrong, lots of people would get something right. Either way, people think more about the show. Kinda like gravity falls way back when. Where the community racked their heads for answers, as each episode came out.

If you're talking about connections to the mind flayer, then I'm pretty sure Max might be another character that will die because she's connected to Vecna, she's just in a coma and maybe her death could lead to the climax of season 5

One of my theories is that Steve is going to sacrifice himself for Jonathan. It will bring it around full circle to season 1 where Steve was bullying him and show how much Steve has changed since then.

Fun fact: The characters named the monsters after the ones from dnd because their powers were similar

It's been forever since Matpat did a video about Stranger Things. Its about time

One thing about Kas’s sword is that it is tied to Nerull, the old evil god of death. It is believed that Nerull corrupted Kas…further corrupted Kas…through the sword, leading to the betrayal. This could be a way to lead to the “there’s another bad guy more powerful than the last one” trope. While the hand and eye are the most iconic, there’s also the heart of Vecna which is in possession of a powerful lich known as Queen Osterneth, the Bronze Lich. She’s quite obscure, but would make a great miniboss on the quest to take out the philacteries. His other most popular artifact is the Book of Vile Darkness. It is so powerful that he keeps it in his ribcage.

I need more will screen time I'm happy he's one of the lead actor in the last season

Great video as usual I thought about this a couple months after the show. But when I was thinking about I was think Will wanting to sacrifice himself for Mike. Since they kinda wink at the idea of Will liking Mike.

I believe that Will is gonna play a major role in season 5. He wasn’t one of the main characters unlike in past seasons and I feel like season 4 was his upbringing season since he wasn’t as active compared to other characters. Also I hope 5th season they fix his haircut they did him mad dirty.

I believe Vecna’s phylactery is actually his childhood home, think about it he is completely attached to it and has his tendrils all throughout the house.

vecna clock could be whats keeping him alive

I think Eddie is done, but maybe will come back as memories, whether flashbacks for motivation or used by Vecna to mess with others. Great character, but his line of not running this time gave him closure and redemption. His uncle got closure, the town/government/media has someone to twist the story onto just like with past events, plus his death will be Dustin's motivation since he is probably the only one with someone to not fight for (actively since Suzie is far away and so far has been a plot forwarding device). Though on that note, I hope that with events probably being covered nationally, maybe Dustin will tell her what's going on, she will somehow get to Hawkins and be the team's techie to aid in the final battle.

I understand that opening part was done more for comedic effect - but First: it's actually interesting how in early editions of D&D to gain levels you should've taken heaps of money to the training facilities because it was sometimes ten times more efficient way to get XP than just by acummulating battle victories. So funny thing: El would have bigger numbers by a lot, because of this military/government funding. And second: as soon as AD&D came to be and further down the road, it has become common to measure characters' expertise by how good they did in three pillars of RPG gameplay, which are: exploration, social interaction and combat. And every life's obstacle, requiring more-than-average effort from the character is considered "an encounter". So it turns out there's a way for them to get quite a good amount of levels, that one could calculate. Although it would require to have comprehensive morphological analysis of each occurrence that's considered an encounter, taking in consideration who of main cast participated where. For 4 seasons each of them running from 8 to 13 hours - that's on par with "What levels is Pikachu" episodes and even harder

Ah yes, Eleven's random sister that never gets mentioned during the entirety of the Henry flashback. Surely she'll save them, somehow. Also the thought of Veccna killing Mike has a much bigger psychological impact if they play into the whole "Will might have feelings for Mike" thing they've been hinting at.

I think that it would be cool if there was a segment of the story where will has to go inside some sort of dreamlike state to take out the part of him with the hive mind.

We need to know how Henry got his powers, it can’t be out of nowhere. Maybe Vecna chose to give him that powers, knowing that he will eventually merge with him and open the portal.

I think another important component is the clock. When you look at the clock there is a key hole on the side of it. The therapist has a necklace with a key and a clock is on the key. Because everyone who visits her winds up dead or is aimed at by vecna, I think the therapist could be working with vecna or at least controlled by him as well.

Hopper wielded an actual sword in the season 4 finale. What if that’s foreshadowing him being Kas? I know it doesn’t make a ton of sense, but it would be interesting to see him as a mind controlled villain

16:51 -Me just imagining how much hate the directors and producers will get if this happens. gosh I can’t even imagine it happening, I’ll probably cry for days if it does

I think time travel will have something to do with it.. Nancy noticed that they went back in time, when they went to her house to get the guns.. 11 will need to go into the upside down, open the original gate, that she 1st created to send 001 to the USD, and if they leave the USD using that gate, they will essentially time travel back to that time, and somehow stop 001 (Maybe using the song that 001 listened to as a little boy) The fact that they even put the scene in, where Nancy notices the travel back through time, tells us time travel will be involved.. because it just doesnt fit in with anything else. I really think we will see some sort of travel through time, and defeating on 001 in the past, to save all the people who died, Barb, Bob, Eddie, Shmirnoff.. ect.

The Duffer brothers DID NOT intend for the show to get more than one season and neither did Netflix at the time. The duffer brothers went back and added the hints that Vecnas there even when he wasnt. Tere are videos on KZfaq about changed scenes because they aren't as clever as people want them to be.

Let's be real. We all wanted this. Also, can we say how weird it is that they go from Demogorgon (demon prince with his own massive swarms of demons he governs), to a mind flayer.... Almost feels like a step down if you think about the dnd part.

This was posted 11 months ago Me: Ok, perfect time to watch it! Get it?

What if part of how Vecna is defeated is by causing him to remember his fondest memories, thus making him vulnerable? I'm not sure whether he may have some pleasant childhood memories, like when he may have been really young, but I do know there is a theory floating around regarding the possibility of him being Eleven's father. That's something that he may have been aware of, but she wasn't, and it may give an interesting twist if in the process of him remembering that, it's revealed to her also. After all, she was also able to see Billy's fondest memory. It would also give Henry telling Eleven that they're alike an even deeper meaning, aside from just saying that because they're both test subjects. It could also be the reason he wanted her to join him. With a twist such as that, I see several possibilities. Also, if Will is to play an important role, which I've been hearing that he is, perhaps this sort of thing could be used to his advantage, seeing as he's able to feel what Vecna feels.

There are so many interesting parallels and symbolism between Will and Henry that I hope you go into, because the proposed ending you have I think is not in the least bit satisfying (even though I enjoy your theories!) I believe the series will end with both Will and El being alive and both of them playing huge roles in ending Vecna
