Noah Langford -November 2120
I don't even realise I've fallen asleep until Kai shakes my shoulder.
For a moment everything feels blurred and disconnected. Sunlight pours through the windows, far brighter than it should be, and my thoughts move sluggishly.
The ache in my neck tells me I've fallen asleep at the desk again, surrounded by open files, empty coffee cups, and glowing monitors I forgot to turn off hours ago.
Then I properly look at Kai.
The concern on his face cuts through the exhaustion immediately.
Before I can say anything, he suddenly steps backwards and presses a hand against his head as though pain hits him without warning. His balance shifts just enough to make panic tighten in my chest.
"Kai?"
I stand quickly, the chair scraping sharply against the floor, and grab his shoulders before he can stumble further. His body feels tense beneath my hands, warmer than normal.
Sweat has already formed across his forehead despite the cold air circulating through the lab, and when his eyes lift to mine they seem distant somehow, unfocused in a way I recognise instantly.
Something is wrong.
"I need you to explain to me what's happening" I say carefully, watching him closely.
Kai lowers his hand from his head and gently wraps his fingers around my wrist, almost like he's trying to reassure me instead of himself.
"I'm fine."
The answer comes too quickly.
"You're clearly not fine." I reply flatly.
He avoids my eyes after that, his gaze drifting toward the desk covered in scattered papers and medical reports.
"Why did you lock yourself in here all night?"
The sudden change in subject catches me off guard, though I should expect it by now. Kai has always been far better at redirecting concern than accepting help himself.
"Kai" I warn quietly, trying to pull his attention back.
But when he looks at me again, there's something distant in his expression that makes me hesitate. He looks exhausted in a way that goes deeper than lack of sleep.
"I was working" I admit.
"On what?"
The coldness in his tone makes something unpleasant twist in my stomach. For half a second it reminds me too much of our father, and the comparison alone is enough to make my chest feel tight.
"I've been helping Dr Edmund and Dr Thomas with the Burnout cure development," I explain. "And analysing your test results."
Admitting that aloud leaves an uncomfortable weight sitting beneath my ribs. I know I'm trying to help him, but under his gaze the exhaustion surrounding me suddenly feels obvious.
Kai sighs softly and lets go of my wrist.
"Noah," he says more gently this time, "you can't keep overworking yourself for my sake."
I release his shoulders and sit back down behind the desk, ignoring the ache spreading through my spine.
"Don't ask something that unreasonable."
I genuinely don't understand how he expects anything else from me. He's my brother. If there's even the slightest possibility I can help him, then sleep stops mattering.
The room falls quiet apart from the low hum of the monitors beside us.
"Now," I say, forcing myself to focus again, "are you going to tell me what's wrong?"
Kai immediately looks away, and I can practically see the hesitation settling over him as he debates whether he should say anything at all.
I already know that expression too well.
"If you refuse to answer," I continue, reaching back toward one of the files on the desk, "then I'll stay here and continue working."
His attention snaps back to me instantly.
For the first time since I woke up, he actually looks more like himself again. The distant expression fades, replaced by familiar frustration and concern.
Kai drags a hand through his hair before finally dropping into the chair beside mine with a defeated sigh.
"Fine," he mutters. "But only after you eat."
He nudges the untouched food container closer to me across the desk, clearly refusing to continue the conversation until I stop neglecting basic human survival.
I want to argue with him, but I already know it would be pointless.
Kai is stubborn in a quiet, immovable way. Once he decides something, he holds onto it with an almost terrifying amount of patience, and judging by the look on his face, he has absolutely no intention of speaking until I eat something first.
Reluctantly, I pull the food container closer and open it.
Heat immediately escapes from inside, carrying the smell of actual proper food instead of the stale coffee and chemical scent that has taken over the lab during the night. Only then do I properly notice the hollow ache in my stomach.
I can't even remember the last time I ate.
Kai notices my hesitation but thankfully says nothing about it.
I start picking absentmindedly at the food while organising the mess spread across the desk beside me. Papers slide into rough piles beneath my hands as I sort through neurological scans, blood reports, and unfinished notes covered in rushed handwriting.
Every few seconds, I glance back at Kai without meaning to.
He sits quietly in the chair beside me, arms resting against his knees while he absently twists his fingers together. The tension that was pulling at his expression earlier seems to have eased slightly now that he's sitting down, and in the softer afternoon light he looks far better than he did yesterday.
At least physically.
Yesterday had been different.
When he collapsed again, I knew immediately something was seriously wrong.
Not just exhaustion, but something deeper.
Before Ethan took Kai back to their room, I'd taken blood samples and strands of hair before anyone could stop me. Ethan had looked horrified when he realised what I was doing, but he hadn't tried to interfere. I think he understood that if I didn't investigate immediately, my mind would never rest.
And it still hasn't.
Finn spent half the night trying to convince me to take a break, but I ignored him.
The problem with knowing too much about biology is that once you notice an inconsistency, your brain refuses to let go of it. Every symptom becomes a variable. Every behavioural change becomes evidence. Every second spent resting feels like wasted time when someone you care about is deteriorating in front of you.
When I analysed Kai's blood samples, the first abnormality became obvious almost immediately.
The regenerative cellular structures we identified in the counterfeit subjects had increased dramatically in his bloodstream after he regained consciousness.
That shouldn't have been possible.
Before now, we'd been concerned by how low the concentration levels were. The working theory was that the lack of regenerative cell activity was preventing proper stabilisation at a cellular level, meaning his body couldn't repair damage efficiently enough to sustain itself long term, which is why he wouldn't wake up.
But after he did, the numbers changed completely.
The increase wasn't gradual either. It spiked aggressively.
I still haven't figured out what triggered it yet.
Stress response... Neurological activity...Adrenaline... Consciousness itself. At this point every possibility still feels equally dangerous. What unsettles me most is that the increase should theoretically be helping him. Instead, he seems different.
I stab my fork absentmindedly into the food while my thoughts continue spiralling through possibilities.
The zoning out, headaches, sudden instability and his elevated temperature.
Neurological involvement seems increasingly likely, which means I'll need more scans, more bloodwork, and probably tissue analysis, if I had the equipment.
The idea alone makes my stomach tighten.
I look over at Kai again.
He catches me staring almost immediately.
"You're analysing me again," he says quietly.
I don't deny it, because he's right.
Even now, part of my brain is cataloguing every movement he makes. The way he keeps flexing his hands. The slight delay before he responds to things. The faint tension around his eyes that suggests the headache never actually faded completely.
Kai lets out a tired sigh and leans back in the chair.
As soon as I finish the last bite of food, I push the container aside and turn my chair fully toward Kai.
"Okay," I say, folding my arms loosely. "Now talk."
Kai glances at me briefly before leaning his head back and stares up at the ceiling lights. For a moment he stays silent, like he's trying to organise the thoughts properly before speaking.
"It's been strange," he finally admits quietly. "Since I woke up."
I immediately pull my notebook closer across the desk and uncap my pen. The motion is automatic. Every symptom matters. Every detail could explain what's happening to him.
Kai notices what I'm doing but doesn't comment on it this time.
"I keep getting headaches" He hesitates for a second before adding, "But my power feels stronger somehow."
My pen pauses against the page.
"In what way?"
Kai lifts one hand slightly and flexes his fingers uncertainly.
The shadows around the lab react instantly.
Darkness shifts faintly beneath the desk, along the corners of the walls, beneath the chairs. It's subtle at first, but once I notice it I can't ignore it. The shadows aren't still anymore. They move in slow restless patterns around him like living things responding to his breathing.
As if they're waiting for something.
Kai stares down at his hand with a faint frown.
"I don't really know how to explain it," he says. "It feels like they're always there now. Just moving. "
As he speaks, a thin mist of shadows curls slowly into his palm without him fully summoning it. The blackness twists between his fingers like smoke suspended underwater.
My mind immediately starts piecing possibilities together faster than I can properly process them.
Increased neurological synchronisation. Heightened responsiveness. Reduced separation between host and ability output.
None of those possibilities are good.
I place the notebook down and quickly pull open the drawer beside me.
"Stay still for a moment," I say as I retrieve a handheld diagnostic reader. "I need to take another reading."
Kai finally looks properly at me as I lean closer and place the small device carefully against his forehead.
For a second, nothing happens.
Then the machine begins to beep.
A display flickers to life on the screen, numbers rapidly climbing as the scanner processes his neural activity and energy output levels.
I stare at the results in silence.
15%.
22%.
31%.
My stomach tightens.
The numbers keep rising.
39%.
44%.
47%.
The display flashes amber.
My chest drops so suddenly it almost feels physical.
"Kai," I say quietly, lowering the scanner slightly. "Your burnout level is at forty-seven percent."
The words sound wrong even as I say them aloud. That should be impossible. As far as I know, he hasn't used his powers enough to trigger another spike. Not after what happened last time.
Which means something else is causing the increase internally.
That would explain the headaches and the instability. But if his burnout levels are rising passively without active power usage, then his body may already be stuck in an accelerated feedback loop.
My thoughts start moving faster.
I immediately grab my laptop and pull up the previous scan results, typing the new numbers into the analysis program while dozens of possibilities spiral through my head at once.
If the counterfeit regenerative cells are amplifying neural pathways connected to his abilities, then the nullifer part of the formulation may not simply be stabilising him anymore.
It may be enhancing the connection itself.
Which means every second his powers remain active could be forcing his nervous system further toward overload.
I barely notice Kai moving until the laptop screen is suddenly pushed downward. I look up sharply and Kai is watching me closely now.
"How is that even possible?" he asks. "I don't feel any of the normal symptoms."
That unsettles me more than the reading itself.
"It might be a side effect of using the counterfeit formulation in the cure," I mutter, rubbing a hand against my forehead as my thoughts continue racing. "The regenerative cells may be interacting with your neural pathways differently than we predicted."
Differently... A dangerously inadequate word.
I lean back slightly in my chair and press my fingers harder against my temple, trying to force my thoughts into something coherent.
I need more data.
I need to understand why his body is behaving like this before the burnout progresses further.
"Noah."
Kai's voice pulls me out of the spiral. I look back up at him immediately and his expression has changed completely. It is more focused and Intense.
"I need to be back up and running," he says firmly. "I need to be able to fight again. No matter what."
For a second I just stare at him, genuinely unable to process what he's saying.
Fight?
After everything that happened?
After he nearly died?
The statement triggers an immediate spike of frustration sharp enough to make my chest tighten.
"How can you even say that?" I ask, my voice quieter than it should be. "Kai, your body is already approaching half-burnout levels without active strain. Plus you only woke up yesterday."
"And people will die if I can't fight."
The answer comes immediately with no hesitation.
Of course it does. Because this is who Kai is.
He will destroy himself without a second thought if it means protecting someone else and somehow that only makes the fear sitting inside my chest worse
I stare at him for several long seconds, waiting for him to take the words back, but he doesn't.
Kai simply holds my gaze while the shadows around the room continue shifting faintly behind him, moving along the walls and beneath the furniture like restless smoke reacting to his emotions.
"You almost died," I say carefully.
"I know."
"You collapsed again yesterday, your burnout levels are rising for reasons we still don't understand, and you're sitting here telling me you want to start fighting again."
Kai exhales slowly and leans back further into the chair.
"I'm telling you I need to. With or without your help"
Frustration tightens in my chest almost immediately.
"Kai, your body is already showing signs of instability. The headaches alone suggest neurological strain, and if the counterfeit regenerative cells are amplifying your abilities internally, then forcing yourself back into combat could permanently damage your nervous system before we even realise what's happening."
"I understand the risks."
"No, you understand them theoretically," I reply sharply. "I'm the one analysing the actual data."
The room falls quiet after that apart from the low hum of the monitors behind me. Kai looks away first, rubbing tiredly at the back of his neck before speaking again.
"You think I want this?" he asks quietly. "Ever since I woke up it feels like the shadows are constantly there now. I can feel them moving even when I'm not using them." His fingers tighten slightly together in his lap. "Everything feels sharper and louder. But despite that, I'm still standing."
I stay silent, listening.
"And if I'm still standing, then i'm fine" he continues, "I can still protect everyone here... I need to protect you and Ethan. No matter what"
Of course that is where his mind goes.
Not himself.
Never himself.
I lean back in my chair and rub a hand across my forehead, exhaustion making my thoughts feel heavier than usual.
"Kai, your definition of being fine is medically horrifying."
The faintest hint of amusement flickers across his face before disappearing again.
"I'm serious."
"So am I."
His expression hardens slightly as he looks back at me.
"You know father won't just let us go. If he decides to attack us and I can't fight because I stayed hidden recovering while people get hurt…" He shakes his head slightly. "I can't do that."
I hate that part of me already understands his reasoning.
Strategically, he is right. We are already short on people capable of handling large scale threats, and Kai's abilities make him one of the strongest fighters we have. But emotionally, the thought of allowing him anywhere near another battle makes me feel sick.
I glance down at the scan results still glowing across my laptop screen.
Forty-seven percent.
The number feels burned into my mind now.
"If I even consider allowing this," I say slowly, "then your training would need to be controlled and monitored properly."
Kai straightens slightly in the chair, though he wisely says nothing yet.
"You would start with limited output sessions only," I continue, my brain already shifting unwillingly into planning mode. "No combat exposure until I can confirm your neural activity remains stable during power usage. I'd need continuous burnout readings, bloodwork before and after training."
Kai watches me carefully.
"And the second I see signs of worsening burnout, we stop completely."
He hesitates slightly. "Noah…"
"I mean it," I interrupt firmly. "If your burnout levels increase unexpectedly, if the headaches worsen, if you dissociate again, if your powers become unstable in any way, then training ends immediately."
The shadows near his chair ripple faintly again before settling.
For a moment Kai says nothing, clearly weighing whether he can tolerate those conditions.
Finally, he nods.
"Okay."
I narrow my eyes slightly.
"You actually mean that?"
"Yes." His voice softens slightly. "I know you're just trying to help me."
That answer catches me off guard more than it should. I look away briefly, reorganising the papers on the desk mostly to avoid the weight of that statement.
"I'm not risking losing you because you decide to ignore your limits again" I mutter quietly.
Kai stays silent for a moment before speaking again.
"I'll stop if things get worse."
There is enough sincerity in his voice that I finally let out a slow breath.
I still hate this idea.
Every instinct I have as both a scientist and his brother tells me this could go horribly wrong. But at least if I monitor him myself, I have a chance of catching the warning signs before it becomes irreversible.
"That doesn't mean I approve of this" I say eventually.
A small smile appears briefly on Kai's face.
"You never approve of anything involving me fighting."
"Because your survival instincts are terrible."
A quiet laugh escapes him at that, soft enough that some of the tension in the room finally eases.
Only slightly.
Because even now my mind is already calculating possibilities, risks, and contingency plans in case his condition worsens the moment training begins again.
