In the omegaverse, "Packless Decay" was a term spoken in hushed tones, often described in medical journals and in the abstract of scientific papers. It was the omegaverse equivalent of hantavirus—a relentless virus that could cause a multi-systemic shutdown. The group that that targeted and prey upon were usually the most vulnerable; omegas, pups that didn't fit in the pack hierarchy or those outcast by society that the world had already deemed disposable.
It was the physical manifestation of a broken spirit: the moment an Omega’s biology surrendered, deciding that a life without a bond was a debt it could no longer afford to pay.
The onset of “Packless Decay Syndrome” was insidious. Notoriously deceptive and characterized by a ‘soft symptomatic phase’, one didn’t notice oneself dying until halfway gone. The early stages easily evaded diagnosis. It started as a restless mind and moved to a sick stomach. Eventually, the body began to treat food like an enemy, refusing the very energy it needed to keep going. By the time it hit the bloodstream, the damage was done. Without the support of a pack, the heart lost its rhythm and slowly faded away until it finally stopped for good.
Seventeen-year-old, vigilante and omega, Tim Drake, had reached the final stage.
It hadn’t been intentional. In all honesty, it has been an accident. For as long as he could remember he’d managed to scrape by on high-dose suppressants and patch stabilizers. But then his supplier got jailed, and by the time he managed to find a new one, his body had stopped responding altogether.
The shutdown had been absolute. Now he was a ghost in a med-bay bed, watched over by four Alphas whose concern was palpable, yet useless against a syndrome they didn't even know he had.
"The fluids aren't holding," Bruce said. His voice was a low rumble that vibrated in the air. He’d been staring at the monitor for a long time now, where Tim’s vitals had been scrolling in a frantic red line. Hypotension. Bradycardia. Sinus arrhythmia. The screen was a checklist of a failing system. Every new alert—the hypercapnia, the gasping tachypnea—felt like another nail being driven into a coffin.
Bruce looked exhausted. Not only were his eyes bloodshot, rimmed with a deep red, they were also hollow, lacking the usually sharp analytic spark that defined him. He couldn't remember the last time he’d actually slept. Not since they brought him here. Every time he allowed his eyelids to be heavy, the image of Tim’s sunken, hollow form and his short staccato breath flared his mind,. It haunted him. He was the world’s greatest detective, a man who could untangle the most complex conspiracies in Gotham, yet he was standing here powerless at the edge of Tim’s bed.
Worst of all, he was failing to solve his own son's case.
The data was right in front of him, but something... something wasn't clicking. The math didn't add up to a standard toxin or injury.
"His body is treating every calorie and every drop of saline as an invader. It’s an autoimmune collapse."
"It’s because he’s a stray," Jason growled from the shadows of the equipment racks from behind. Like a tiger who’d been caged for too long, he paced back and forth. It was clear Jason had been spiraling down this particular hole for hours, his mind miles ahead than the others, who were still frantically grasping for any medical solution that made sense.
"He’s been a stray for too long," Jason continued, his voice a jagged edge. His usually sharp, clean gunpowder scent had curdled into something bitter and metallic, like the aftermath of a lightning strike. "He’s been playing the lone wolf on black-market patches and sheer spite, and now his instincts have turned feral."
The atmosphere in the room shifted, turning thick and suffocating. The air grew heavy and sour as their collective distress spiked. Bruce’s scent of rain and ozone turned to the rank, stagnant smell of a coming storm, and Dick’s bright citrus rotted into a sharp, acidic vinegar that stung the back of the throat.
Even Damian, standing rigid by the monitors, gave off a scent like burnt cedar, dry and choking.
Jason stopped, his eyes fixed on Tim’s seizing form. "He’s literally dying of stress because his body thinks we’re here to finish him off. To him, we aren't family; we're just a cornering threat."
"He wouldn’t let us in," Dick whispered, his voice cracking. He could finally see the picture clearly. "Every time I tried to scent him, he’d pull away. Every time we invited him to a pack movie night or a den-pile, he had an excuse. A case. A lead. He thought he was being 'independent.' He didn't realize he was starving himself to death."
A wet, rattling cough tore through Tim. A thin, high-pitched whine—the sound of an Omega in total distress—echoed off the stone walls.
"The statistical probability of survival drops to a negligible two percent once the convulsions manifest," Damian stated, his tone a flat, dissonant chord. His hand tightened on the edge of the metal tray until the steel groaned under the pressure. "He is currently at ninety-seven. We are effectively observing a corpse that has yet to stop twitching."
"Then I suggest that Bruce better stop playing doctor and start being an Alpha!" Jason yelled, the tenuous thread of patience snapping all at once. His eyes were glowing with a predatory, protective heat. It looked like he was about to throw hands if someone didn't do something.
"Look at him, Bruce! He’s slipping! He doesn't need more IVs or oxygen masks. He needs a reason for his heart to keep beating! We need to find him a reason to stay!"
Bruce looked from the monitors to the boy on the bed. Tim was a genius, a detective, a hero—but right now, stripped of the suit and the gadgets, he could see the image more clearly. How underneath it all, Tim was just a dying Omega whose soul was untethered.
"Move the equipment," Bruce commanded peremptorily
Dick and Jason didn't hesitate. They shoved the rolling monitors and the IV stands back, took the oxygen mask, and created a small, clear space on the oversized medical cot.
Bruce moved with a staticky, desperate gravity. "Tim," he rumbled. He didn't use the voice he used for the Mission; he used the Alpha Command, a deep, resonant frequency designed to cut through the noise to reach pack. It wasn't a directive to Tim to obey, but a tether—a primal invitation to remain in the land of the living.
He climbed onto the bed, the frame creaking under his weight. He sat against the headboard and hooked his arms under Tim’s pits, dragging the younger man’s limp, fever-slicked body up against his chest.
The contact was a physical shock to Tim’s haywire system. Instead of a scream, a thin, broken whine escaped his throat—a high, confused sound of a pup that had forgotten what it was like to be held. It was the sound of a creature that didn't know if it was being comforted or consumed.
On the monitor, Tim’s heart rate spiked into a blurred, frantic line, the alarm a continuous, panicked shriek.
"Too much," Jason hissed, his own scent of bitter char thickening in the air. "He's drowning in you, Bruce! His brain thinks you're the predator that finally caught him."
Bruce didn't pull away. Instead, he bared the scent glands at his neck, forcing a heavy, rhythmic pulse of calm, rain-drenched earth directly into Tim’s space. He was trying to overwrite the "trespasser" signal with the "protected" one, but the air in the med-bay was a toxic soup. Dick moved in on the other side, rubbing his scent-heavy wrists against Tim’s cooling ankles, adding a frantic, cloying sweetness to the mix.
The room smelled like a battlefield of desperate love—a suffocating wall of Alpha pheromones that was supposed to be a sanctuary, but felt like a cage.
Tim’s head lolled back against Bruce’s shoulder, his eyes unfocused and glazed. Another whine vibrated in his chest, weaker this time, as his body struggled to decide whether to fight the embrace or finally, fatally, go still within it.
"Easy, pup," Bruce rumbled, his chest vibrating against Tim’s back. He turned his head and pressed his throat—the most vulnerable part of an Alpha—directly against Tim’s nose. He forced his scent glands to open wide, flooding the immediate air with the smell of the "Home." It was the scent of the Manor’s library, of the damp earth of the Cave, and of the deep, unshakable safety of a father.
The air in the med-bay was thick enough to choke on, a toxic cloud of adrenaline and fear until Dick shifted. He leaned in, pressing his forehead against Tim’s temple, and began to purr as well.
It wasn't a sound humans were supposed to be able to make; it was a low, visceral thrumming that started deep in his chest and vibrated through his ribs. In Alpha biology, it was a physical metronome—a biological "stop" command designed to synchronize a frantic pup’s heart rate with the steady rhythm of the Pack-Alpha.
On the other side of the cot, Damian’s mask finally shattered.
His hand, still crushing the edge of the metal tray, trembled before he let go. He was the youngest, the only one among them still technically classified as a pup in the eyes of biology, and the instinct to answer a pack-call was a lure he couldn't resist.
Damian stepped forward, his movements uncharacteristically jerky. He didn't ask for permission, instead he climbed onto the edge of the bed at Tim’s feet, curling his small, rigid frame. Then, he joined in.
He purred.
Damian’s purr was higher, a sharper tone—the frantic, demanding thrum of a younger brother refusing to let a pack-mate drift away.
The sound filled the room, two different frequencies of Alpha protection layering over one another until the very air seemed to vibrate. It was a wall of sound, a sensory cage of "You are ours" that began to drown out the mechanical yelps of the heart monitor.
Tim’s body convulsed once, a sharp, jagged twitch, and then he let out another long, stuttering whine. But this time, the sound was less terrifying. His head drifted, chin tilting up instinctively toward the source of the vibration in Bruce’s chest, his senses overwhelmed by the sheer crushing weight of a pack that refused to let him be "packless" for even a second longer.
"He's reacting," Jason whispered, his own throat working as if he were fighting the urge to add his own roar to the chorus. "Look at the line. It's smoothing out."
The monitor was still red, still frantic, but the jagged peaks were rounding off. The 'Decay' was meeting a force it didn't know how to fight: a pack that had decided to stop being a "threat" and start being a heartbeat.
Jason climbed onto the bed from the other side. He didn't do "gentle" well, but he did "solid." He draped his heavy legs over Tim’s and wrapped his massive arms around both Tim and Dick, effectively sandwiching the dying boy in a wall of Alpha heat and muscle.
For a terrifying minute, it seemed like it was too late. Tim continued to shake, his skin remaining cold and clammy despite the four bodies pressed against him. His scent remained a toxic, sour miasma of "Packless Decay."
"Come on, Timmy," Dick pleaded, his purr faltering for a second. "Just take a breath. Just smell us. We’re right here. You’re not a trespasser. This is your den. We’ve been waiting for you to come home."
Jason growled, a deep, vibrating sound that was meant to ward off the "sickness" itself. "You don't get to check out, kid. You don't get to die because you're stubborn. Open your scent glands and fight back, or so help me, I’ll drag you back myself."
Deep within the haze of his failing organs, Tim felt the shift. For weeks, the world had been a blur of white noise and sharp pain. He had felt like he was floating in the dark. He had been so tired. The "sickness" had told him that it was okay to let go, that he didn't have a place, that he was an anomaly—an Omega who didn't have a pack.
But now, the dark was being pushed back by a tide of warmth. He smelled Bruce, Dick, Jason. He even smelled Damian now, whose puppish scent of milk and woodsmoke—uncharacteristically soft and pleading—told him he didn't have to be alone anymore.
It was an overpowering scent that commanded him to go with the pack, to stop fighting the warmth and just be with them. His senses were overwhelmed by the sheer, crushing weight of a pack that refused to let him be "packless" for even a second longer.
Tim’s hand, which had been limp on the sheet, twitched. His fingers curled, catching the fabric of Bruce’s shirt. He let out a sob—not a whine of distress, but a broken, ragged sound of relief. He buried his face into the crook of Bruce’s neck, his teeth grazing the skin in a desperate, uncoordinated attempt to "claim."
"That’s it," Bruce whispered, his large hand coming up to cradle the back of Tim’s head, shielding him from the rest of the world. "I’ve got you. The pack has you."
The monitors began to change. The frantic, jagged red lines slowed. The blood pressure, which had been bottoming out, began to stabilize as Tim’s nervous system finally exited "flight or fight" mode and entered "protected."
The biology of the Omega was a strange thing. Tim’s body began to heal the moment the bond was acknowledged. The "Decay" couldn't survive in the presence of a functioning pack. The pheromones acted like a key, unlocking Tim’s ability to process the fluids and the nutrients that were being pumped into his veins.
The room, once filled with the scent of death and antiseptics, was now thick with the heavy, musk-sweet aroma of a "Pack." It was a scent that meant stay. It meant ours.
Hours passed. None of them moved. Tim was no longer shaking. His skin had regained a faint and healthy flush. His breathing, on the other hand, was deep and synchronized with Bruce’s. He was still exhausted—his body would probably need weeks to fully recover from the physical toll of the decline of his system—but the risk of a “shutdown” was gone.
"He’s asleep," Dick whispered, his head resting on Tim’s shoulder.
"He’s grounding," Jason corrected, though his voice was uncharacteristically soft. He hadn't let go of Tim’s hand. "Look at the vitals. He’s finally resting."
Bruce looked down at the boy in his arms. Tim looked younger when he was asleep, the lines of worry and the weight of being a "detective" smoothed away by the biological safety of the bond.
"He’ll try to apologize when he wakes up," Bruce said, his eyes finally closing as he allowed himself to feel the relief he had been suppressing. "He’ll try to say he’s sorry for being a burden."
"And we’ll tell him he’s an idiot," Jason muttered, though there was no heat in it.
"We’ll tell him he’s home," Dick said.
In the quiet of the Cave, the five of them remained tangled together—a pack that had been broken, now fused back together by the very thing that had almost destroyed it.
Tim Drake was no longer packless.
He was anchored, he was claimed, and for the first time in a long time, he was safe.
The mortality rate of the world outside didn't matter; inside the den, the only thing that existed was the breath of the pack.
