do you think Mikeās behavior towards Will in S2 would somehow parallel his behavior towards El in S3?
Interesting ask! I like that comparison, though they are starkly different in nature. LETS THINK!!
So what you mean to point out is the glaring shift in attention from Will to El between seasons. I might've talked about this in an earlier post, but I love talking about it anyway, so let's dive in lmao.
So, I feel like it's pretty fair to say Mike is quite the easily-attatched, obsessive kind of person. And not in an insane way, at least not all the time, but you can see it in every season and in the way he sets his priorities. I mean, every season he finds something to latch onto and makes it his entire personality till something new comes along. And that's sort of what happened between seasons 2 and 3.
In season 2, Mike's sole purpose was to be by Will's side and to help figure out what was going on with him and the mind flayer. He was the one that was the most involved with his possession other than Joyce, and since he's just naturally such a leader and a genuinely objective-driven person, it was the only thing he focused on or worried about at all frankly all season.
Mike's determination to find Will in season one was his initial fixation, and I don't mean to use the term fixation to lessen the meaning of how much he invested himself in it. It's mainly a better way to express just how hyperfocused he gets in things like that. Mike nearly killed himself in season 1 for the slight chance that they might find Will again. WTF!? Anyway, season two was no different. With Will, his determination and general need to be of help is so prominent and almost default to him. It's really revealing of his priorities, the mere fact that he didn't go anywhere else for a solid few days while he watched over Will and wracked his brain for anything that could help fix the situation.
And that all changed, of course, with the reintroduction of El at the end of the second season. Of course, Mike still helped figure out how to stop the Mind Flayer without killing Will, but it was at that point that we knew once this was all over, his attention would shift to El in a similar manner.
Now, there's a bit of a difference in the behavior from season 2 to season 3 in terms of how he expresses that "obsession" or as we should probably just call it, "fixation." In season 2, it was driven with the intention of being helpful to Will in any and all ways that he could, whether that be comfort (the scene on his bed where they talk about the Mind Flayer), rationality (helping Joyce, Bob, Hopper etc. figure out the connections and offer useful understanding), or just company for a slowly deteriorating Will Byers, which can be backed up by the way he was solely with Will for a far majority of the season.
In season 3, the fixation he has for El is a little less within the area of his expertise, and lot more forced. And that's not at all to say that he just up and goes to El's cabin at the same time every day against his will lmfao. I really just mean that the organicness with which he latched onto Will's situation couldn't exactly be replicated here. Mike doesn't really get fixated on something without there being an end result or something useful to come out of it. So... that is to say he most definitely still had a goal in mind with his relationship with El. It's really just part of his formula and the recurring patterns presented in each season with every action he takes. Despite being an idiot, he's very methodical in what he does. And that's no different with El.
Mike after getting a girlfriend and thus eradicating the loser allegations:
Basically, what I'm saying is a regurgitation of what plenty of others have said on this app, and it's that he wants very badly, whether he knows it or not, to do one of three things:
for himself to come off as normal and typical teenage boy-ish as possible
for himself to come off as non-homosexual as possible
to prove to everyone that he is not "weird", as so many others have suspected (his bullies, his parents, literally everyone)
But, to be fair, those are all basically the same things. At least in Mike's book. And in his mind, a lot of his issues with not fitting in and the internal fear of being seen have a solution within his relationship with El. With her, he finds an excuse to back out of all of the things that remind him of just how "weird" he is. Turning down Dungeons and Dragons, the Cerebro setup, and indulging in all that teenager-y romance drama and moodiness was so out of character for him, and I feel like that really means something in the grand scheme. There have been many analyses on the stark capitalistic, bright and flashy artificiality of season 3, and Mike was a MAJOR part of that, especially in his drastic change in persona in just that season. (Note this analysis of his clothes in s3 I chimed in on as well, because it fits well with this lmao). Now, so many things that he once loved to do before can now be turned down with the excuse that he has someone. Someone (a girlfriend) that symbolizes (to society and by default, to him) manhood and true maturity and whatnot. She, to him, can be the light at the end of the bleak tunnel called life in Hawkins, Indiana, where he can't be who he wants, but he can settle for a questionable relationship with a friend that excuses all of that weirdness (*cough* queerness *coughcough*) in him that he can't seem to shake without her.
It's smart of him, really. I mean, he likes her! They've gone through a lot together, and having a good friend that he can easily deem as someone he like likes despite not really knowing what he wants is just him taking easy street. Sadly, he neglected to realize that pretending to be in love with someone might cause said someone to fall in love too. Someone innocent, new to the world, and susceptible to that kind of feeling. BAD IDEA MICHEAL.
He saw a lot of the repercussions of that in season 4, where El's feelings came a lot more into play and the whole "being normal" and "getting girlfriends" deal had begun to wear off in his mind. His relationship with DnD came back with that too, and I think it has a lot to do with his realization that he fucked up. Big time. Season 4 is really a whole other story. Basically him trying to salvage their relationship despite realizing his attraction toward her was all a lie. He didn't really like like her, he just liked the idea of being relieved of his societal expectations by being with her. And once he met Eddie and learned that conformity is what's killing the kids, it finally dawned on him that he really dated El solely to conform. And that's fucked up. And he realizes this. But isn't sure how to fix it.
Oh well, that's an issue for season 5 to resolve.
My purpose for writing this is not to confirm Byler or to shoot down M!ileven. All I hope to do is offer script-centered reasoning and analysis for the events depicted in the show, so that it can help connect the dots on what may happen next. Truthfully, whether Mike ends up gay, straight, with Will, with El, or WHATEVER, I truly believe that the narrative in season 4 intends for us to pick up on the fact that Mike has come to the realization that he isn't in love with El, he never was really, and that he is dealing with the shockwaves that his too-young compulsory love decision has wrought for them. It is kind of his fault, because despite being young and stupid when he initiated it between them, she was even younger and stupider and happened to follow his lead. (I love El, I am NOT calling her stupid lmfao I just mean he sort of used her lack of knowledge and experience in society to his advantage unknowingly and led them down the path to where they are now.)
Anyway, that's what I think about Mike's behavior between seasons. Sorry, this was unnecessarily long, but I hope it answered your question LMFAO.
Please shoot me a message or another ask if there's any more questions or thing you'd like me to expand more on! Y'all know I can yap for hours over this.
