We literally do know though? The series literally states that MF was being controlled by Henry and was essentially an extension of Henry. MF doesnt have its own mind. Why do you think Will has a link to Henry if it was just MF targeting Will? If it was actually MF acting on his own, then Will only would have a connection to MF alone but he has a connection to Henry and he knows how he thinks and feels and what kind of a state he is in. It is Henry that he is feeling, not the Mind Flayer. It is Henry that Will remembers his memories, not the Mind Flayer's. I don't understand why people ignore that and downplay what Will went through by saying it was just the Mind Flayer. It was Henry, I am not sure why people keep denying this?
Also it is not much of a theory anymore, it is clear that Henry is the one who targeted and captured Will to the Upside Down too. You can make the argument that all of Will's trauma starts from that point. Because Henry just keeps coming for Will and traumatize him.
All of Will's trauma is because of Henry and it starts with Henry. If anything, Will should be the key player to take him down alongside El. But for El, at least you can make the argument that all of her trauma starts because of Brenner. It is Brenner who stole and kidnapped her, stripped her off of her childhood, it is Brenner that made El's mother lose her mind. It is Brenner who experimented on El and it is Brenner who started all that lab mess in the first place. Henry plays a role in that too, but for El her problems start because of Brenner.
For Will, it all starts because of Henry. It is Henry who targeted and kidnapped him to the Upside Down. It is Henry who used the MF to target Will again, specifically because he is the one to kidnap Will in the first place for reasons that have not fully revealed. It is Henry who possessed Will because again-- if it was just the MF possessing Will, then he only would have sensed MF. He doesnt though. Now it is revealed that he has a direct link to Henry.
What I mean is that all of Will's trauma starts because of Henry and it continues because of Henry. It is important to address because people keep downplaying it by saying it was just the demogorgon or the mind flayer that targeted him when it is clear now that it wasnt.
i see what you’re saying, but we actually never see will being linked to henry. his episodes are triggered by the mind flayer. those memories are the mind flayer’s, because they show us that when we see will mentally searching the tunnels. i agree that henry was the one who led to his initial kidnapping, but beyond that there hasn’t been a direct connection made between henry and will beyond the parallels. i think henry did target will, but the mind flayer is the one actually causing all the horrible things will goes through with being possessed and never being freed from that feeling whenever it’s near.
also, we don’t have confirmation that henry is controlling the mind flayer. that scene of henry shaping the mind flayer was entirely from henry’s perspective, one which is very skewed. unreliable narration happens constantly in this show, so we’re only being led to believe that henry controls the mind flayer because henry believes he controls the mind flayer. the mind flayer itself is a being of great power, but it isn’t able to open gates: it gave henry more strength in order for them to achieve a common goal. what we are told about the mind flayer, based on the comparison given by dustin, is that it does have a consciousness and that it seeks to conquer other worlds. that lines up with the mind flayer doing more than just targeting will, but also trying to extend itself into hawkins over and over again.
henry didn’t possess will. the mind flayer did. henry doesn’t trigger will’s episodes. the mind flayer does. henry may have started the process, but the mind flayer has continuously gone after will and affected him.
also, comparing brenner to henry doesn’t make much sense. brenner abused el for 12 straight years, manipulated her, and hid the world from her. he was the source of a vast majority of her trauma; henry is not the source of will’s trauma, simply the person who set it in motion.
and, i literally said i don’t want el to be the one to kill henry because it pushes her story, but rather because it pushes henry’s. henry needs an ending that will not just kill him, but one that makes him realize that everything he’s done has been for nothing and that he’ll never be able to achieve his goal because of his choices. anyone could kill henry, but i think el would be the one who makes the most sense for henry’s story. other antagonists are given an ending in a way that makes sense, and that needs to apply to henry too.
el got her peace with brenner, and that was a fantastic choice because brenner’s death was necessary for el’s arc. henry’s death is important for both will and el, but henry just doesn’t have that personal connection with will that he has with el.
thanks for making a counter argument though!! i think i addressed all the points you made, but if i missed something lmk :) my memory of s4 is a bit hazy because i haven’t rewatched it in a hot minute, so if i find some stuff that disproves my points or supports them, i may come back and address those
