#steve also has the prehensile demobat tails btw

[xenon-demon]

Something something steddie role swap AU. Steve and Eddie swap places for the final fight against Vecna (because you don’t really need to be able to play the guitar to make a distraction with one, and Steve is already injured while Eddie is Not), things proceed as in canon - the bats get in, Steve is self-sacrificial because that’s the Steve Harrington Agenda™, Steve gets himself killed.

Dustin has to watch his older brother die in his arms. Robin has to come back from a fight that she’s pretty sure they lost to find the other half of her soul is gone. Lucas finds out that not only has he lost Max, but he’s also lost his role model, one of his biggest supporters. Eddie is stuck in a town that’s falling apart, filled with people that hate him, and the only people who will understand are mourning someone Eddie barely knew. Someone whose shoes Eddie is never going to be able to fill, even when he feels like he has to try because that’s what he does; protect his people. And no matter how fucked the circumstances that got them here are, he’s decided these are his people now.

(They have to be, now that not even Uncle Wayne can calm him down when he has the nightmares, seeing Chrissy’s lifeless eyes staring down at him as he hears her bones crunch and twist-)

Eddie can’t breathe with how the gaping absence of Steve Harrington is threatening to swallow him whole. It’s always there, in the way Robin is isolating herself, sleeping over in Steve’s empty house whenever she can, and no one can get her to talk about it. It’s in the way Dustin, overcome with grief, keeps oscillating between blaming Eddie for agreeing to switch places and blaming himself for suggesting it in the first place. It’s in the way Eddie wonders sometimes, as he turns the events of Spring Break over in his mind, if maybe there was something there, or could have been something - and then he’s immediately overcome with guilt, because he’s lusting after a ghost. A ghost of someone he didn’t even know, really, as he’s learning more and more every day about the ways Steve has changed since high school.

So after a few weeks of this, especially with the added stress of Hawkins falling apart at the seams and being constantly invaded by hellbeasts from the gaping portals all over town, Eddie does what he does best.

He runs away.

He doesn’t even think about where he’s going, just puts one foot in front of the other - even as he crosses over a portal into the Upside Down, one near the trailer park, he doesn’t let himself stop and think. If he does that, he’s going to have a panic attack, and having one of those here in Hell is absolutely going to get him killed, the otherworldly hisses and screams echoing around him amongst the trees are a pretty potent reminder-

There’s a snap behind him, sounding way too close for comfort. Eddie spins around, heart racing in his chest, tensed and ready to run if he has to.

There’s nothing there. Nothing living, at least, because Eddie can see a broken branch just dangling down from one of the trees he just walked past. From this far away, it looks like something has pulled down on it, snapping the top part of the branch and leaving it attached at the bottom by just a thin layer of wood. It’s such a tenuous connection that the branch is bobbing slightly under the weight of gravity, and it looks like at some point it might just break under its own weight.

The main problem with this is that it was definitely a whole, intact branch when he first walked past it.

Eddie finds himself taking a few steps forward without really thinking about it. As he gets closer, his heartbeat gets louder and louder until he can hear it pounding in his ears. He feels a deep sense of wrongness here, like something - someone, maybe - is watching him, waiting for some kind of trigger. It crawls up his spine like a spider, making his skin crawl, his shoulders twitching involuntarily.

The feeling only intensifies when he’s within arms reach of the broken branch. It’s like a block of ice gets dropped into his chest, the way he suddenly goes cold; from this distance, he can see the branch is thicker than his upper arm. Whatever it was that did this, it’s stronger than a human, that’s for sure. Eddie feels the sharp buzz of panic begin to settle over his body, is dimly aware of a hysterical noise starting to bubble up within him-

The breath is slammed out of his lungs, too quickly to even scream. At the same time, he feels pain bloom across his upper body from being grabbed by the shoulder and shoved up against the tree. Eddie feels pinpricks of pain all up his back, his thin Iron Maiden t-shirt doing little to protect his skin from the tree bark.

Eddie’s eyes are screwed tight as he waits for the inevitable; he’s seen enough of this place to know he doesn’t want to see whatever it is that’s about to kill him. He feels something sharp scrape against his neck, followed by a pressure along the underside of his jaw, and his last coherent thought is, Jesus Christ, can’t believe I’m leaving Henderson fatherless.

Except... he doesn’t die. Eddie Munson keeps breathing, quick and shallow gasps with his eyes still tightly shut. It doesn’t make any sense, his brain can’t even begin to process what’s happening to him, so after a few seconds - when he’s sure he’s actually still alive, and not just having a delayed reaction to being eaten - Eddie opens his eyes. Immediately he feels like throwing up.

Because there in front of him, mere inches away from his face, face twisted into an utterly chilling smile, is Steve Harrington.

Or at least - something that was Steve Harrington, once upon a time. The creature now in front of Eddie has- christ, where does Eddie even begin. He doesn’t know where to look first, his brain overloading trying to take it all in - Steve has fangs now, that Eddie’s certain of, sharpened canines that jut out under Steve’s top lip and glint whenever lightning crackles overhead. He can see streaks of what looks like dried blood trailing down Steve’s chin from the fangs, following his neck downwards until they’re lost in the ring of scar tissue and dried blood at the base of his neck where he got choked by the demobats.

Most captivating of all, though, are Steve’s eyes. Once he makes eye contact, Eddie can’t bring himself to tear his eyes away. Steve’s eyes have always looked pretty to Eddie, in that strange middle ground where they look brown in some lights and almost green in others, but now they shine with a soft golden glow in the darkness. He’s not quite sure, it’s hard to focus enough to be sure, but Eddie thinks his pupils are no longer human-like, instead vertical slits like a cat’s eye.

Now that Eddie’s made eye contact, out his peripheral vision he sees Steve’s grin grow impossibly wider. At the same time, that pressure around his neck gets worse momentarily as Steve squeezes, oh fuck, he has his hand around Eddie’s throat. That sharp prickling sensation is back again, too, and Christ Almighty he’s pretty sure Steve has fucking claws.

Steve leans in even closer, and Eddie feels his breath fan across his face as he drawls, “Did you miss me too, baby?”
