The Wheeler house has been hollowed out.
In the Upside Down, it isn’t ruined so much as possessed- the familiar shape of home stretched over something ancient and hungry. The front door hangs crooked on one hinge. The walls breathe, subtly, like lungs remembering how to function. Vines crawl along the siding and disappear into the cracks, threading their way inside as if the house itself invited them in.
Mike descends the basement stairs with his heart in his throat, Will at his side, eyes white.
Each step creaks too loudly. The sound echoes wrong, bouncing back at him from angles that don’t exist in the real world. Spores drift lazily through the air, glowing faintly gray, sticking to his hair and his jacket. He doesn’t bother brushing them away. His hands are shaking too badly.
Above him, beside him, below him- everywhere- there is war.
The Upside Down sky pulses red through the planks of the boarded-up basement windows. Distant booms roll through the ground, the sound of Hawkins fighting back: explosions, the roar of something enormous ripping itself to shreds, El’s power cracking the air like thunder. Somewhere far away, people are screaming. Somewhere closer, something shrieks in pain.
But down here-
Down here is quiet.
Too quiet.
Mike reaches the bottom of the stairs with Will and stops. Carefully, he lays Will down on the couch and crouches beside him, beads of sweat dropping down his face.
The basement looks like a memory someone left out in the rain.
The old couch is half-collapsed, swallowed by black growth. The support beams are wrapped in thick vines that pulse faintly, as if pumping blood. The concrete floor is slick with something dark and organic, etched over with symbols burned deep into the surface- circles, lines, maps, all layered on top of each other until Hawkins and The Abyss blur together.
And in the center of it all-
Will.
Mike’s breath leaves him in a broken sound.
Will lies on the couch, his body unnaturally still, arms slack at his sides. Candles burn around him, their flames bending inward like they’re bowing. The drawings on the floor tremble, lines shifting and realigning themselves every few seconds, like the world can’t decide what shape it’s supposed to be.
For half a second, Mike can’t move.
“You’re the heart”
But Mike feels like his own heart has stopped beating.
All he can see is Will’s face- too pale, lashes dark against his cheeks, lips parted just enough to show shallow, uneven breaths. Black veins faintly along his neck, fading in and out like a bad signal.
“No,” Mike whispers, panicked. The words feel torn out of him. “No, no, no-”
His knees dig into the ground, screaming in protest. He can’t feel it.
“Will,” he says again, louder now. “Hey. Hey, I’m here.”
Nothing.
Mike reaches for Will’s hand.
It’s warm.
Too warm- feverish, burning, like his body is working overtime to keep him anchored here.
“Oh my- shit,” Mike breathes. His fingers curl tight around Will’s. “Please. Please wake up.”
The air thickens.
“Mike,” Will softly acknowledges. His voice is butter, soft and exhausted and achingly familiar. It sounds like Will always sounds when he’s trying not to scare anyone.
Mike presses his free hand to his forehead, fighting the sting behind his eyes. “Yeah,” he says hoarsely. “Yeah, I hear you.”
“You should go help the others. I’ll be fine.”
“Yeah, well,” Mike huffs weakly, leaning closer, “you don’t get to make that call. I’m the heart, right?”
The basement reacts to that.
The vines along the walls tense, shuddering as if something beneath them has noticed. The candles flare higher, wax running like tears. Somewhere deep in the house, something large shifts, the sound reverberating through the beams.
Mike swallows hard.
He can feel it now- the other presence. Not a body. Not a face.
A pressure.
Vecna isn’t standing in the room, but he’s threaded through it, woven into the walls and the floor and Will himself. Every breath Will takes feels like it’s being watched.
Wills’ fingers twitch in Mike’s grip.
“It’s almost done,” Will strains. “Vecna- I- I can feel him getting weaker. If I break the connection here, the merge can’t complete.”
Mike’s chest tightens painfully.
“Break the connection?” he repeats. “Will, what does that mean?”
There’s a pause.
Not silence- because the world never stops screaming, not since 1983, but a hesitation so deliberate it terrifies Mike to his core.
“It means that… all of this is over. Once and for all.”
“No,” Mike says too fast, shaking his head. “No. Absolutely not.”
“Mike-”
“No,” he snaps, tears finally spilling over. “You don’t get to decide that. Not like this.”
The basement shakes violently, dust raining down as something slams into the house above them. One of the support beams cracks with a sharp, awful sound.
Will’s face tightens, jaw clenching as if he’s biting back pain.
“If I don’t do this,” Will spoke, agony creeping into his voice, “he’ll keep using me. I can feel him everywhere. In Hawkins. In here. I’m the last thread holding him in place.”
Mike grips Will’s hand harder, like he can physically anchor him.
“You’re not a thread,” Mike argues fiercely. “You’re- you’re not just something he gets to use.”
“I’ve always been the connection. This is how it’s always been.”
“That doesn’t mean you’re expendable!”
Will’s breathing falters.
Mike leans down until he’s sobbing into Will’s chest, ignoring the heat radiating off Will’s skin.
“You listen to me,” Mike says, voice shaking but determined. “You don’t get to disappear again. You don’t get to decide everyone’s better off without you.”
The air grows heavy, pressing in on them from all sides. The black veins on the walls pulse faster, creeping closer to the circle.
“He’s getting closer,” Will warns. “Mike, you have to go-”
“No,” Mike asserts. “I spent years being afraid of the wrong things. I’m not doing that anymore.”
Mike doesn’t pull away when Will’s eyes open.
If anything, he leans deeper into him, fear creeping up his back, shielding Will because he couldn’t before.
“I keep thinking about the time you first disappeared,” Mike says, his voice low and shaking. “About how I didn’t know what was happening, just that you were gone. And it felt like the world had… shifted wrong. Like someone had taken a piece out of it and expected the rest of us not to notice.”
The pressure in the basement pulses, agitated.
“I told myself it was fear,” Mike continues. “That I was scared because you were my friend. Because that’s what made sense. Because that’s what I was allowed to feel.”
He lets out a breath that sounds like it’s been trapped at the bottom of his lungs for years.
“But the truth is, I’ve always known that it was you. When something is wrong with you. My chest tightens. I can’t really think straight, I guess. It’s like nothing else in the world matters to me anymore.”
His grip tightens in Will’s jacket, fingers curling like he’s trying to hold on to the final piece of Will, and that he might dissolve any second.
“I watched you come back from the dead, and I promised myself I’d protect you. And then I didn’t. Not really. I let you stand behind me. I let you think you were less important. I let you think you were… replaceable.”
Will’s breath stutters, a choked sob escaping his throat.
“I thought if I said it out loud- if I admitted what this is- I’d lose everything,” Mike says, tears slipping free now, unashamed. “My parents. My friends. Myself. You. I thought it meant I was weak, or unstable. Or that I’d turn into someone my dad would look at and not recognize.”
The house creaks, vines shriveling as Vecna’s influence falters.
“But what actually hurt me,” Mike says, voice breaking, “was watching you believe you didn’t matter to me. Watching you be willing to die because you thought that was all you were good for.”
Mike shakes his head in defiance, a small, furious movement.
“You’re not a weapon. You’re not a sorcerer. You’re not some sacrifice.” His hand squeezes Will’s even harder. “You’re the kid who said yes to being my friend on the first day of kindergarten. You’re the reason I knew I wasn’t alone before I even understood what that meant.”
He laughs weakly, breath hitching.
“You’re the person I look for in every room. You’re the one I trust when nothing else makes sense to me. And I don’t care how long it takes me to unlearn all of the complete bullshit I was taught to be afraid of- I’m not losing you because of it.”
The pressure snaps violently, like a cord pulled too tight and finally breaking.
“I love you,” Mike says, his voice steady and confident this time. “Not as a best friend. Not as some half-thing I can explain away. I love you, Will. And I hope that lameass Vecna can hear this, because I’m choosing you over everything. Right now. Out loud.”
For a moment, the world genuinely seems to hold its breath.
Then WIll inhales sharply, a real, full breath, and his hand fists in Mike’s palm like it's the only solid thing left in existence.
“Mike,” he says, voice wrecked. “You’re here.”
“I’m not going anywhere,” Mike says immediately. “Ever.”
Will moves first.
It’s tentative at first, unsure of which direction it’s headed in. His lips brush Mike’s, barely there, a question more than a kiss.
Mike answers without hesitation.
He kisses Will like he’s been waiting his entire life to do it- careful but desperate, hands coming up to cradle Will’s face, thumbs warm against his tear-streaked cheeks. Will exhales into the kiss, a soft, broken sound that feels like relief, like grief finally letting go.
The world doesn’t end.
The kiss deepens, slow and grounding. Will’s fingers curl into Mike’s hair, pulling him closer, like he needs the contact to stay tethered to reality. Mike feels the warmth of Will’s mouth, the familiar closeness that has always existed between then now given a real form.
It’s not fireworks.
It’s something steadier, grounded.
It’s the feeling of that final puzzle piece clicking into place after being lost for years.
When they pull back, they’re both shaking, breaths mingling.
Will smiles- small, disbelieving, real.
“You stayed,” he whispers.
Mike presses a kiss to his forehead, then his temple, then back to his lips, softer this time.
“Always,” he says.
And above them, the cursed, harsh red lightning fades- not gone, but retreating- as the world begins, slowly, to scab over.
