The barricade did not become safer because they finished building it.
It only became quiet.
That was worse in its own way.
Daren kept one hand on the filing cabinet after the others stepped back, palm flat against the dented metal, waiting for the next impact to travel through it. None came. The desks pressed against the door remained where they were. The cabinet leaned at an ugly angle. One chair leg stuck out from the heap like a broken bone.
Outside, the corridor continued to exist.
That was all the silence proved.
Mara stood with her sword lowered, but not sheathed. The classroom had no sheath for what she had become, no place where metal could stop meaning threat. Her eyes moved from the barricade to the windows, from the windows to the ceiling tiles, and finally to Kael.
He sat between the teacher's desk and the wall, propped against two chair cushions and a stack of textbooks someone had abandoned before the world learned how little coursework mattered. His head had tipped sideways. His right hand rested on the floor, fingers spread as if he still expected the room to tilt.
His left arm lay across his lap.
Wrong.
Carefully wrong.
Lena knelt in front of him with the supply bag open beside her.
"Don't sleep yet," she said.
Kael's eyes opened a little.
"I wasn't."
"You were."
"Then I was bad at it."
His voice came thin, scraped raw by pain and thirst, but it came.
That alone made Lena's jaw tighten.
She hated how quickly relief could become another thing to fear.
Eli slid down the wall near the covered windows and hugged the IV pole against his chest. The pole's wheels clicked once against the tile. He looked down at them as if the sound had betrayed them all.
"Sorry," he whispered.
"No one is hunting us by wheel noise," Daren said.
Eli stared at him.
"You don't know that."
Daren opened his mouth.
Then closed it.
"Fine. I don't know that."
Jonas stood near the teacher's desk, sorting the contents of the bag with hands that tried to be calm and failed in small places.
Gauze.
Two disinfectant wipes.
One sealed water bottle.
A cracked plastic bottle with half its label torn away.
Three adhesive strips curled at the edges.
A roll of medical tape nearly empty.
A pair of gloves stuck together by dried blood.
He set each item on the desk as if position could make them more useful.
"That's all?" Mara asked.
Jonas looked at the line of supplies.
"That's all we took."
"It's not enough," Eli said.
Mara did not look at him.
"We already had that conversation."
"Right." Eli swallowed. "Still hate the answer."
"So do I."
That made him blink.
Mara turned toward the windows before his face could do anything with the honesty.
The classroom sat on the second floor. Outside the glass, the campus had gone dark while they were too busy surviving to notice. Emergency light and smoke broke the night into uneven layers. Rain had become a thin mist against the panes. It blurred the courtyard beyond into a smear of black stone, fallen shapes, and distant red pulses from alarms no one had silenced.
One window was cracked from corner to corner, but the pane remained in place. Another had a small hole through the upper half. Not a bullet, probably. Something smaller. Faster. Angrier at glass than physics.
Mara touched the frame with two fingers.
"Windows stay covered."
"With what?" Eli asked.
Mara looked at the posters curling on the walls.
Eli followed her gaze.
"Exam schedules," he said. "Great. Finally useful."
Daren pushed himself away from the filing cabinet.
"I'll do it."
"You'll make noise," Jonas said.
"I make less noise than panic."
No one argued with that.
Daren started stripping posters from the walls. He moved carefully for a man his size, peeling tape slowly, jaw tight, axe balanced within reach against a desk. Eli stood after a moment and helped, because doing something with his hands was better than listening to the room breathe.
Lena did not look away from Kael.
"Can you drink?"
He gave the water bottle a wary look.
"Probably."
"That wasn't an answer."
"It was the closest thing I had."
She twisted the cap, wiped the rim with the cleaner side of her sleeve, then hesitated.
One bottle.
One sealed bottle for six living people and whatever counted as a few hours.
Kael saw the hesitation.
"Don't."
Lena's eyes flicked up.
"Don't what?"
"Use it all on me."
"I wasn't planning to drown you."
"You know what I mean."
"Yes," she said. "That's why I'm ignoring you."
She poured a little water into the cap instead of giving him the bottle. Her hand shook only after the water touched plastic.
Kael lifted his right hand.
It did not reach.
He stared at it for a second with something close to insult.
Lena raised the cap to his mouth.
"Slow."
He drank too fast anyway.
His throat closed halfway through the swallow. He coughed, folded forward, and the room tightened around him. Lena's hand went to the gauze. Daren stopped with a poster half-peeled from the wall. Mara turned. Jonas stepped closer without knowing what he intended to do.
Kael pressed his right hand against the floor until his fingers whitened.
The cough passed.
The wound held.
Lena did not breathe until it did.
"Slow," she repeated, softer this time and more angry for it.
Kael's eyes watered. He nodded once.
The next sip stayed down.
Then another.
Three caps of water.
Lena stopped after the fourth.
Kael looked at the bottle.
His body wanted the rest badly enough that he hated it.
Lena screwed the cap back on.
"Later."
He nodded again.
His lips were wet now. That felt absurdly intimate, like a luxury stolen from a world that had not agreed to keep producing luxuries.
Daren finished covering the cracked window with two exam posters and a ripped notice about academic integrity. Eli taped the edges with strips torn from another poster, because wasting medical tape on glass felt obscene. The result looked ridiculous, wrinkled and uneven, but it broke the line of sight from outside.
"Anyone else impressed by how ugly that is?" Eli asked.
"No," Mara said.
"I am."
"Be impressed quietly."
He nodded and pressed the last strip into place.
Jonas crouched near Kael's left side.
"We need to immobilize the arm."
Kael closed his eyes.
"Love that sentence."
"We're not setting it," Lena said immediately.
Daren looked over.
"Should we?"
"No."
The answer came too fast.
Lena heard it too and forced herself to slow down.
"No," she said again. "Not here. Not with this. Not when we don't know how bad it is."
Daren studied Kael's arm.
"It's broken."
"It might be broken in more than one place."
"Ah."
"And if we pull wrong, we could make it worse."
Daren looked at Kael.
"Can it get worse?"
Kael opened one eye.
"I'd rather not test how creative the universe is."
"Fair."
Jonas had already turned toward the chairs. He chose one with a loose wooden support beneath the seat and worked it free with careful pressure until the joint cracked softly.
Everyone froze.
Nothing answered from outside.
Jonas exhaled through his nose.
"Sorry."
"Wheel noise and chair cracking," Eli murmured. "We're basically musicians."
Daren gave him a look.
Eli lifted both hands.
"Quiet musicians."
They used the chair support, torn cloth from Eli's ruined hoodie, and the least bloody part of Kael's jacket to brace the arm. Lena directed with short sentences. Jonas obeyed. Daren held Kael's shoulder when the first wrap pulled the limb an inch too high.
Kael did not scream.
That frightened Lena more than a scream would have.
His face went empty. His mouth parted. His whole body locked around a pain too large to spend on sound.
"Stop," Lena said.
Jonas stopped instantly.
Kael blinked once.
The room came back to him in pieces.
Ceiling tile.
Dust.
Lena's hands.
Daren's sleeve beneath his fingers.
His own breath, trying to saw him open from the inside.
Stay here.
The thought did not feel brave.
It felt like an instruction written on the last wall inside him.
"Kael," Lena said.
He found her face.
"Still here."
The words were almost nothing.
They landed anyway.
Lena looked away first.
"Good."
Jonas finished the wrap more slowly. When it was done, the broken arm rested against Kael's chest, ugly but still. The stillness helped. It also made the injury harder to deny.
Kael looked at it for too long.
"That's mine?" he asked.
No one answered quickly enough.
His mouth twitched.
"Bad sign."
"It's yours," Lena said.
"Unfortunately," Daren added.
Lena glared at him.
Kael made a sound that might have become a laugh in a kinder room.
It hurt him enough that he stopped.
Mara dragged a desk away from the center of the classroom and set it on its side beneath the covered window. Then she pulled two more into position, building a low barrier between the glass and the rest of them.
"Barricade the windows too?" Eli asked.
"Slow anything that gets through."
"That wasn't a no."
"It was the shape no takes now."
Eli accepted that with a small nod and helped.
They rearranged the classroom by inches.
Desks became walls. Chairs became braces. The old order of the room vanished under the slow, ugly logic of survival. A place built for sitting, listening, and pretending the future could be scheduled by semester became a place for angles, weight, blocked sightlines, and things heavy enough to buy seconds.
A map of emergency evacuation routes, darkened by mildew, was pulled from the wall and spread across the teacher's desk. Jonas smoothed it flat with both hands, then frowned when half the ink came away on his palm.
"Useful?" Mara asked.
"Maybe."
"What does maybe mean?"
"It means the building used to make sense."
Daren leaned over the map.
"Stairs?"
Jonas pointed.
"Here and here. If this map is accurate, we're near the east wing. There should be bathrooms down the hall, vending machines near the lecture rooms, and maybe a staff lounge farther north."
"Bathrooms mean water," Lena said.
"Maybe."
Daren looked at Jonas.
"You use that word a lot."
"The world keeps earning it."
Mara's gaze stayed on the map.
"Bathrooms first when we move. Water, medicine, cloth, anything sealed. We do not open rooms unless we have to. We do not split more than one door apart. We do not chase sounds. We do not investigate anything because it might help."
Eli raised a hand halfway.
"What if it is definitely help?"
"Then we discuss how likely it is to kill us first."
"That feels fair."
Daren tapped the map with two fingers.
"When?"
Mara looked at Kael.
Lena did too.
Kael hated that his body had become the clock.
"Not now," Lena said.
Mara did not argue.
"For a few hours if we are lucky."
Daren glanced at the barricade.
"Luck has been performing badly."
"Then we use the few hours before it remembers us."
That ended it.
For a while, they worked without speaking.
Daren checked the barricade until his hands were black with dust and dried blood. Mara inspected the ceiling tiles, lifting one with the tip of her sword and staring into the dark gap above until Eli begged her with his eyes to stop doing that. Jonas gathered anything that could become useful. Pens. A stapler. Scissors from the teacher's drawer. A small roll of tape. A phone charger with no phone.
He also kept three chalk sticks, though the classroom had no chalkboard.
No one asked why.
Eli found a half-full bottle of hand sanitizer in a drawer and held it up like a relic.
"Treasure."
Lena looked over.
"Give it to me."
"It says lavender."
"Eli."
"Right. Medical treasure."
He brought it to her.
She used a little on her hands, then immediately regretted the smell.
Lavender spread through the classroom, thin and false, too clean for the blood on their clothes. For one awful second, the room smelled almost normal.
Kael's stomach turned.
The scent did not belong here.
It belonged to bathrooms, backpacks, people caring what their hands smelled like before lunch. It belonged to a world where cleanliness had been a habit instead of a strategy against infection.
Then the smell reached deeper.
Not memory.
Almost memory.
White light behind closed eyelids.
A cold sleeve around his arm.
A voice asking him to squeeze if he could hear.
Kael's right hand twitched.
Lena saw it.
"What?"
He swallowed.
"Nothing."
"You're very bad at nothing."
"Smell."
"The sanitizer?"
He nodded once.
"Bad?"
"No."
The answer was true and not true enough.
He could not explain that the smell had pressed against a door inside his skull and found it locked from the other side.
"Just strange."
Lena studied him for a moment, then capped the bottle.
"Fine. We use less."
"I didn't say—"
"I heard what you didn't say."
Kael looked at her.
She looked away before the moment became too soft to survive.
Jonas set the scissors, tape, and charger on the desk.
"We should talk about watches."
"No one sleeps," Daren said.
Eli made a small sound that was almost a sob and almost a laugh.
"That's a plan made by someone who is going to fall asleep standing."
Daren looked offended.
"I don't fall asleep standing."
"You look like a statue someone forgot to finish."
"I look fine."
"You have blood in your eyebrow."
"That's not structural."
Mara cut through them before Eli could answer.
"Two awake at all times. One at the door. One at the windows. Lena rests first."
Lena's head snapped up.
"No."
"That was not a suggestion."
"I'm not leaving him."
"You are sitting three feet from him and your hands are shaking."
"They're fine."
Mara crossed the room.
Every step was quiet.
That made it harder to ignore.
"They are not."
Lena curled her fingers into her palms.
"I can still work."
"Yes," Mara said. "That is why you will rest before you stop being able to."
The room held its breath around the two of them.
Lena's face tightened.
For a moment, Kael thought she would refuse again. Then Mara's expression changed by almost nothing. Not softness. Not pity. Recognition, maybe.
"You bought him time," Mara said.
Lena went still.
"Do not spend the rest of yourself proving it counted."
The sentence entered the room and found every bruise.
Lena looked down at her own hands.
There was blood beneath her nails. Kael's, mostly. Some not.
She nodded once.
It was small enough to be a wound.
"Fine."
"Good."
"I rest beside him."
"I assumed."
Lena shifted from kneeling to sitting against the wall near Kael's right side. She did not lie down. Mara let that pass.
Daren took the door first. Mara took the windows. Jonas sat at the teacher's desk with the ruined map in front of him, though his eyes moved more often to Kael than to any exit route. Eli curled near the wall with the IV pole across his knees.
No one slept at first.
Then exhaustion began making liars of them.
It started with Eli.
His head dipped once, jerked up, dipped again. He opened his eyes too wide and stared at the covered window like concentration could replace consciousness. The third time, his chin hit his chest and stayed there.
Daren looked at him from the door.
"Useful."
Mara's voice came low from the window.
"Let him."
"He's holding a pole."
"He's not on watch."
Daren grunted, but said nothing else.
Jonas lasted longer. He wrote something on the back of an exam poster with a pen that only worked when held nearly vertical. His handwriting started precise and grew worse by the line.
East wing.
Bathrooms likely.
Water uncertain.
Unknown creature in hall.
Vent access dangerous.
Kael stabilized.
He paused after that last word.
Then added a question mark.
Kael saw it from across the room.
"Rude."
Jonas looked up, startled.
"I thought you were asleep."
"Everyone keeps accusing me of that."
"It's because you keep almost doing it."
Kael closed his eyes.
"Jealous."
Jonas smiled faintly.
It disappeared quickly.
"How is the pain?"
Kael considered lying.
The effort sounded exhausting.
"Everywhere is competing."
"That bad?"
"That organized."
Jonas's pen stopped moving.
Lena's eyes were closed beside Kael, but her voice came anyway.
"Fever?"
Jonas reached out and touched the back of his fingers to Kael's forehead. He was awkward about it, as if afraid the gesture might mean more than measurement.
"Warm."
Lena opened her eyes.
"How warm?"
"Too warm for comfort. Not enough for certainty."
Daren snorted softly from the door.
"Maybe."
Jonas ignored him.
Kael swallowed. His mouth had already gone dry again.
Under his ribs, the hunger remained curled tight and quiet.
It had not vanished.
That mattered.
But it had stopped leaning toward anything.
That mattered too.
The sealed wound throbbed with each heartbeat. Not in rhythm exactly. Close enough to make him aware of both. His heart worked. The wound held. The thing beneath the wound listened with the patience of a closed mouth.
Thock.
Pressure.
Thock.
Heat.
Thock.
Still here.
He did not want to sleep.
Sleep meant losing the room.
Sleep meant trusting other bodies to notice danger before his own did. Sleep meant the dark behind his eyes, and the dark behind his eyes had not been empty lately.
Still, his body began taking him by degrees.
The classroom blurred.
The barricade became a shape.
The covered windows became pale rectangles.
Mara's sword became a line.
Lena's shoulder rested near his without touching. She had finally slipped sideways, eyes closed, chin tilted down, one hand still open on the floor between them. Not holding him. Close enough to become pressure if his wound changed.
Kael looked at that hand until his vision softened.
Don't make her do it again.
He did not know whether the thought was a promise, a prayer, or just pain trying to sound useful.
For a while, nothing tried the door.
That did not make the room safe.
It only made the room theirs.
For a few hours, if Mara was right.
For less, if she was not.
Across the room, Daren watched the barricade. Mara watched the covered windows. Jonas watched the map until his eyes stopped reading it. Eli slept with both hands around the IV pole.
No one looked peaceful.
That was all right.
Peace belonged to rooms that expected morning.
This one only promised not to kill them yet.
Under Kael's ribs, the hunger stayed curled and quiet.
Thock.
Still there.
Thock.
Still his.
Thock.
Eventually, his body took what his mind refused to give it.
Kael slept sitting up.
And the room held.
