It has been days since Elias had been able to sleep in past dawn.

He drifted inside it, carried by lists and the quiet scrape of thought. Sera’s words kept returning like a tide he could not ignore.

You are not human anymore.

Incorrect, every trained part of him argued.

He had lived with protocols for years, each step nailed down with double checks and sterile gloves.

He had watched vials, logged batches, recorded adverse events until numbers felt safer than air. He trusted the chain more than he trusted memory.

But chains break. He knew that, too.

He eased onto a stool at the far end of the kitchen counter and opened a notebook.

His handwriting had always been neat enough to pack into small spaces, precise enough that anyone on his team could read it. It looked the same now. That alone calmed him.

Observation: Unusual stamina in cold.

Observation: Night vision improved beyond normal range.

Observation: Minor aches resolve faster than expected.

Hypothesis: Adrenaline, training, diet.

Alternative: Mutation as a result of the vaccine.

He underlined the last word, then frowned at it as if the mark might burn through the page.

Laughter drifted from the living room—Lachlan low and warm, Alexei bright and careless. Zubair’s voice cut through once, the tone that ended arguments without raising volume. Sera’s reply followed, short and final.

The rhythm of the KAS team plus one was beginning to feel normal, if anything about this new world could claim the word.

He turned his attention to his body, the lab he could not leave.

He pressed his fingertips along his forearm, finding the faint yellow where a bruise should have been purple. 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

He checked his pulse: steady, a fraction slower than yesterday after a similar run of stairs.

He timed his breath and counted to sixty without the ache he expected. He flexed his hands and watched tendons rise and fall like small animals under skin.

"What are you doing?" Lachlan asked from the doorway, a mug of tea cupped in both his hands.

"Gathering data," Elias replied, a little too crisp. "Do not mind me."

Lachlan leaned one shoulder to the frame. "Sera was right, you know. Not human anymore doesn’t have to be a curse."

"Language shapes thought," Elias countered, eyes still on his wrist. "I prefer accuracy until the data insists on poetry."

Lachlan lifted the mug in truce and drifted away.

Elias inhaled and reached for the small steel bowl he had filled with snow earlier.

The crystals had melted to slush, but the temperature still bit when he held it for too long.

He plunged his hand in up to the wrist and started counting in his head.

Pain arrived on time, a clean edge that should have forced him to stop by thirty.

He reached sixty.

He passed ninety.

He felt discomfort, yes, but not the sharp warning his training taught him to trust. He withdrew his hand, watched the skin pink, watched the capillaries answer without delay.

He dried his wrist on a towel and wrote ’Tolerance to cold increased’. He added a question mark he did not like.

The corner of the page wrinkled under his thumb. He smoothed it, irritated at himself for caring about paper when the world wore ice.

He listened, the way he had learned to listen for a change in a patient’s breath down a long hall.

The tower’s bones gave their soft creak. The greenhouse fans turned. Zubair’s spoon struck the pot in a slow, steady rhythm, a metronome for someone else’s patience.

Luci’s nails tapped once against tile, then stilled.

Elias slid the notebook aside and stared at his hands.

He had always liked them: capable, clean, trained.

He turned them palm up, palm down.

The small nicks across the knuckles from moving crates two days ago had faded almost as soon as they appeared. He rubbed a thumb across the place where a paper cut should have complained and felt nothing but smooth skin.

"Coincidence," he muttered. "You are tired. You missed the window when the bruise looked worst. You are making stories where none exist."

He stood and crossed to the hall where the light ran thin.

He fixed his focus on the darkest corner and let his pupils adjust.

The corner did not vanish. It resolved. A torn thread on the hem of a curtain. A faint scratch where Luci’s small claws had tested the baseboard the first night.

Dust on the edge of a frame that had been out of reach until Sera introduced them to walls as ladders.

He pinched the bridge of his nose and returned to the counter. The notebook waited, patient as a good instrument. He wrote ’Vision: low-light acuity abnormal’ and underlined the word abnormal twice.

He reached for the snow bowl again and stopped, fingers suspended over the rim. He did not want to invent an injury to test healing.

He refused to cross that line.

But he could watch time.

He drew a small circle with pen on the back of his hand, pressed hard enough to raise the skin.

He waited.

The line should have remained for several minutes, impressed by pressure. It vanished in one.

"Adrenaline," he argued with himself. "Warm room. Good circulation."

Sera walked past the entry to the kitchen then, Luci trotting in her shadow.

She did not pause. She did not need to. Her presence altered temperature by existing.

Luci glanced up at Elias and blinked a slow, serious blink that looked older than he was.

Elias tried to blink back with equal gravity and failed.

Alexei laughed from the couch, voice carrying. "He’s judging your notes."

"He can take my practicum when he is literate," Elias returned without looking away from the pup.

Sera’s hand dropped for a half-second to brush Luci’s ear.

The gesture warmed the entire room more efficiently than the fire. Elias watched the line of her mouth and wrote Leadership remains constant; change under control.

The note belonged nowhere on his list, but it settled something essential.

He rolled his shoulders and returned to the snow. Hand in. Count. Breath steady.

The bite came, but it did not own him.

He reached one hundred again, pulled free, and pressed his palm flat to the counter to watch the color return.

"You are not human anymore," he rehearsed under his breath, testing the shape of the phrase in his mouth like a pill he refused to swallow. "You are not—"

The capillary refill was too fast to ignore. He did not write it. He did not need to.

He closed the notebook and left it on the counter, pen balanced across the top like a lever.

In the living room Lachlan was telling Luci a story about a dog from his childhood who had eaten an entire loaf of bread and then apologized for a week.

Alexei was pretending not to listen and failing. Zubair watched the stairs between stirs as if the act itself could call Sera down. The tower hummed. The day held.

Elias flexed his hands once more and stared at them as if they belonged to someone he would meet soon. He did not fear them yet. He did not trust them either.

"Science first," he reminded himself, voice too quiet to travel. "Belief later."

His fingers hovered over the snow a third time, suspended between what he had been and what the ice wanted him to become.

He lowered them in and kept counting, breath even, eyes on nothing and everything all at once.
