My brain has created a fun amalgamation of these two posts (link, link)
Steph deciding after Startcourt life is way too short to continue living it for anyone else and immediately starts transitioning, everyone who matters in her life is of course accepting. and the rest of Hawkins is too wrapped up in the drama of the mall to notice that Steph and Steve are the same person, its just assumed Steve got out of dodge after the mall burned down.
the party starts going to hellfire and Stephs babysitter mode activates because these people don't know what monsters and references could set her kids off so she decides to tell Eddie what he is not allowed to use in his campaign or even mention around them. She goes in boymode because no one knows Steph but Steve still has a reputation.
Eddie is very very confused when Steve Harrington approaches him and immediately gets into what he is not under any circumstances to mention in front of the newest members of hellfire and its got to be the weirdest prank or something because the kids have never mentioned knowing Steve at all and all and the only connection Eddie knows about it that Steve is Nancy's ex which would not explain this behavior at all. so of course he has to test it, to disastrous results they do a good job at putting on a brave face but its clear they're terrified and as soon as the session is called they pull out a walkie and start calling for check ins. a voice that must be the mysterious badass and beautiful babysitter Steph that they're constantly going on about tells them to stay put and that she'll come in and get them. they protest that they aren't kids anymore but she isn't hearing it.
Eddies excited to get to see her for himself to see if she really is all they've built her up to be or is this is just a childhood crush clouding their judgment. he decided they haven't been doing her enough justice as she swings the door open and is doing head counts and visual wellness checks backlit from the fluorescents in the hall way like some kind of angel. once shes assured of the partys safety she rounds on him hands on hips looking so bitchy and disappointed "you used something off the list didn't you" it isn't a question. the party catches her attention before he can untie his tongue ruffling hair and giving half hugs, he'll have to thank them latter because the wave goodbye Henderson gives him is definitely conspiratorial like he was taking her attention on purpose.
It takes a day after the weirdness that was the last hellfire meeting for curiosity to get the best of him and he goes to get answers, he has no idea where Steph lives but he's sold at enough Harrington house parties to find his way. Imagine his surprise when its Steph that opens the door and starts talking to him like they've actually conversed before. Like she was the one that gave him the list of things not to mention, while simultaneously dressing him down for not listening.
for at least a brief moment Eddie assumes Steph is dating herself, it would explain how she knows about his conversation with Steve why Steve felt it was his place to tell him about the monsters, maybe she had been busy and he'd offered to go in her stead, and why she was answering his door.
She explains that she can't actually explain all that much about why he cant use demogorgons and mindflayers in his campaigns, because NDAs are a bitch. but does give him what she can leaving him even more curious because what the hell did a bunch of 14 year olds get into in Hawkins that require NDAs
before he leaves though he has to ask how she knows steve because that shouldn't be some huge secret.
Steph looks like a deer in headlights for a moment before doubling over with laughter, snorting hard to breathe crying laughter ( it really shouldn't be as cute as it was) once shes composed herself enough she just states "I am steve"
