Chapter 31: The Halloween Episode
POV: Adam
October 31st, and Hawkins Middle School buzzes with costume excitement that feels obscene when weighed against the warnings screaming through Adam's system like air raid sirens announcing the end of the world. Children parade through hallways dressed as ghosts and goblins, innocent monsters that pale in comparison to the real nightmare preparing to manifest through his brother's increasingly fragile consciousness.

[RECOMMENDED ACTION: PREPARE FOR DIMENSIONAL BREACH]
Today. It happens today. Will's last day of being entirely human.
The Byers house thrums with domestic energy that feels like the calm before atomic storms. Joyce attacks Halloween preparations with the manic enthusiasm of someone who's decided that normal traditions can force reality to cooperate, while Bob documents everything with his camcorder—dad jokes and paternal pride wrapped in RadioShack polyester.
"Hold still, Will," Joyce says, adjusting the proton pack she's constructed with impressive attention to Ghostbusters authenticity. "I want to make sure the lights work properly."
She made it herself. Spent hours in the garage with wire and batteries, creating something that brings joy to her son's face.
Will stands patiently while Joyce fusses with LED arrays and switch configurations, but Adam reads tension in his brother's posture that has nothing to do with costume adjustments. Something fundamental is wrong—Will moves like he's listening to sounds only he can hear, his eyes tracking movement that doesn't exist in normal reality.
"You okay?" Adam asks quietly while Joyce adjusts his own Ghostbusters uniform.
Fifty-eight percent. The infection is approaching critical mass.
Will forces a smile that doesn't quite reach his eyes. "Yeah. Just... feeling weird. Like something's watching me."
Something is watching you. The Mind Flayer is preparing to make you its primary host.
Bob films everything with the dedication of someone who's discovered the joy of family documentation, his enthusiasm infectious despite the undercurrent of approaching catastrophe.
"This is going to be the best Halloween ever," Bob announces, zooming in on Will's proton pack with professional focus. "Wait until the other kids see these costumes. You guys are going to be the hit of the neighborhood."
If we survive the night. If Will survives the night as himself.
The afternoon passes in a blur of final preparations and forced normalcy. Max arrives at the designated meeting point with a costume that perfectly captures her personality—punk rock witch, all attitude and carefully controlled rebellion. Lucas and Dustin immediately begin competing for her attention while Mike maintains hostile distance that makes group dynamics feel like diplomatic negotiations.
The Party is fracturing just when we need unity most. And I can't explain why that matters without revealing everything.
As evening approaches and they begin their trick-or-treating circuit, Adam maintains constant surveillance of Will through their empathic link. His brother's emotional state fluctuates wildly—moments of genuine Halloween joy interrupted by flashes of terror that taste like dimensional static.
He's fighting it. Will's consciousness is fighting the Mind Flayer's influence, but he's losing ground.
They're walking down Maple Street, candy bags growing heavy with suburban generosity, when it happens. Will freezes in the middle of the street, his eyes rolling back to reveal only white while his consciousness gets pulled somewhere else entirely.
No. Not here. Not in front of everyone.
Adam lunges forward, catching Will before he falls to the asphalt, and suddenly he's pulled into the vision through their brotherly bond—swept into the Upside Down where a massive shadow creature looms over them both like a living storm.
The Mind Flayer.
Ancient. Hungry. Impossibly vast.
It regards them with intelligence that predates human civilization, appendages made of storm clouds and malevolence writhing with predatory satisfaction. Through Will's terrified perception, Adam feels the creature's attention like physical weight—crushing, inescapable, absolutely without mercy.
"You cannot hide from me forever, little spy. Soon you will be mine completely."
The voice comes from everywhere and nowhere, bypassing normal hearing to resonate directly in their consciousness. Will's terror floods through the empathic link like ice water in Adam's veins, making his borrowed body convulse with sympathetic trauma.
Get out. GET OUT OF MY BROTHER.
When the vision snaps back to normal reality, both boys are screaming. Will collapses in Adam's arms while trick-or-treaters scatter like startled birds, parents rushing to help children they assume are having some kind of Halloween-induced panic attack.
"Will! Adam!" Mike's voice cuts through the chaos. "What happened?"
What happened is that the most powerful entity in the Upside Down just claimed my brother as its primary host.
"It found me," Will gasps, clinging to Adam with desperate strength. "The shadow monster. It knows where I am now."
It's always known where you are. It's been building its connection through you for months.
Joyce arrives in a screech of tires and maternal panic, bundling both boys into the car while demanding explanations no one can provide. The drive to Hawkins Lab passes in a blur of medical jargon and desperate questions, Dr. Owens running tests that can't detect dimensional parasites while Will describes visions that sound like psychotic breaks to anyone who hasn't seen the Upside Down firsthand.
"It's massive," Will whispers to the assembled adults while Adam holds his hand and counts heartbeats. "Like a spider, but made of shadow and storm. And it's so angry. Always hungry, always angry."
Hungry for our dimension. Angry that humans exist independent of its control.
While the adults debate treatment options and containment protocols, Adam excuses himself to the bathroom and checks his system readings with growing dread.

[MIND FLAYER ENTITY CONFIRMED]
[CLASSIFICATION: HIVE LORD]
[THREAT LEVEL: EXTREME]
[RECOMMENDED ACTION: PREPARE CONTAINMENT PROTOCOLS]
Using the camera hidden in his jacket, Adam documents every detail of the lab's layout—exits, security measures, holding cells that might become necessary if Will's possession accelerates beyond the point of normal medical intervention.
If the Mind Flayer takes complete control, we'll need somewhere to contain him without destroying his body.

[SUCCESSFUL CRISIS MANAGEMENT]
That night, they return to the Byers house under medical supervision, Will sedated but still restless, his dreams invaded by visions of spreading shadow and ancient malevolence. Adam lies awake in the next bed, listening to his brother's whimpers while counting the creatures he's positioned around the house like a defensive perimeter.
Four Demodogs. Six Vine Crawlers. Scout on overwatch. It won't be nearly enough when the Mind Flayer makes its move.
Through the bond, Scout sends updates from patrol routes that now include monitoring for dimensional incursions. The creature network is detecting increased activity at weak points throughout Hawkins—reality preparing to tear open like infected flesh.
Tomorrow, Will won't be Will anymore. Tomorrow, the real war begins.
And I'm the only one who knows what's really coming.
But as sleep finally claims him, Adam makes a silent promise to the darkness and the horrors it contains.
I saved you once, little brother. I'll save you again.
Whatever it costs. Whatever I have to reveal.
The Mind Flayer wants a war? It's got one.
