Kryptonians, for all their grandeur, were still animals once.
Beneath the steel and intellect of their civilization lay something older — the instinct to build, to prepare, to nest. Long before they learned to bend gravity or harness suns, they learned to soften a place for the ones they loved.
It wasn’t about walls or architecture. It was about presence.
A Kryptonian’s scent, the heat from their hands, the order they imposed on the space around them — that was the unspoken act of claiming, of protection. When the time came to welcome a child, that instinct became holy.
------
Clark remembered when it first happened to him.
When Lois was pregnant with Jon, he couldn’t stop rearranging things. It started small — changing the curtains, repainting a wall, making the air feel softer. He’d hover above the crib at night, his hearing tuned to the pulse of two hearts: Lois’s steady rhythm and Jon’s fluttering heartbeat, small and erratic like a bird in the womb.
He built that nursery like his body demanded it.
Every pillow was chosen by touch, every blanket tested for warmth. He spent hours folding, smoothing, refolding — unaware that what he was really doing was building a nest.
And when Jon was born, Clark swaddled him in one of his own shirts.
It was instinct, pure and primal — the child breathing in his father’s scent, imprinting safety through something as simple as air. When Jon stirred in his sleep, Clark would lift him close, and the baby would calm instantly, as if recognizing the rhythm that once surrounded him in the dark.
That was what love felt like to a Kryptonian — scent, warmth, nearness. The universe translated emotion through skin.
Years later, the instinct returned.
But this time, the child in question wasn’t a newborn. He was a boy already grown — too quiet, too careful, with a look that carried both defiance and apology.
Conner.
Clark didn’t expect the old instinct to wake again, but it did — quietly, insistently.
He found himself straightening Conner’s room, picking out sheets, replacing the cold lamp with a warmer light. It wasn’t the same kind of love as with Jon — this one was riddled with guilt and hesitation, the kind that blooms after years of absence.
He caught himself buying things Conner hadn’t asked for: books, gloves, a weighted blanket. Lois teased him for overcompensating.
“You’re nesting again,” she said one evening, smiling softly. “You did the same thing with Jon.”
Clark laughed it off, but he knew she was right.
He was nesting. Not for a baby this time — but for forgiveness.
Conner had been living with them for a few weeks now. The boy tried — he helped around the house, played with Jon, answered Lois’s questions with polite half-smiles. But there was always distance, a thin film of restraint around him, as if he was afraid of leaving fingerprints on anything that wasn’t his.
Clark noticed he never fully unpacked. His room looked too neat, too temporary.
Except for one thing: an old black shirt folded on the desk or draped over the back of a chair, always close, always within reach.
Sometimes Conner wore it when the evenings turned cold. Sometimes Clark saw him fiddling with its sleeve while reading or while watching Jon’s cartoons.
It was a strange, small detail — yet it clung to Clark’s attention like a burr.
The fabric didn’t look new. It didn’t even look like something Conner would buy for himself. It carried a faint, foreign scent — smoke, cedar, and something colder, more deliberate. Not his scent. Not Kryptonian warmth. Something human. Something like Gotham.
Clark didn’t mention it.
But every time he walked past Conner’s door and caught a whiff of that other scent, something wordless inside him tensed.
When he held Jon, he used to smell home — the familiar blend of sunlight, air, and earth that was his own. But when Conner passed by in that black shirt, Clark smelled Bruce.
And he didn’t understand why that stung.
He told himself it didn’t matter. It was just clothing. He told himself Conner had been through enough — let him keep whatever made him comfortable. He told himself all the right things, but none of them silenced the quiet unease building behind his ribs.
Every evening, when Conner retreated to his room and closed the door, Clark would find himself standing outside it, listening to the muffled rustle of fabric, the soft creak of the mattress, the quiet rhythm of breathing that was almost — almost — relaxed.
The air around that door always smelled faintly of cedar and ash.
And though Clark couldn’t explain why, it made his chest ache.
------
The house had settled into a rhythm — three heartbeats and one more, always slightly out of sync.
Mornings came with the smell of coffee, Jon’s laughter, Lois’s voice calling for breakfast. Clark tried to believe it was enough — that Conner sitting at the table, spooning cereal in silence, was proof they were finally becoming a family.
But there were small things that didn’t fit.
Conner never reached for second helpings, even when Lois cooked his favorites. He never left his jacket on the couch or forgot his shoes by the door. He moved through the Kent household like a polite guest, careful not to disturb the air.
Clark noticed these things.
He noticed everything.
He noticed how Conner always folded his clothes in perfect rectangles, how he lined up his boots with precision. He noticed the soft clicks in Conner’s jaw when Lois brushed against certain topics — school, friends, Cadmus.
And, more than anything, he noticed the shirt.
The old black one.
The one Conner wore almost every other day, its fabric faded, the collar slightly torn.
Jon called it “the Gotham shirt.” He said it teasingly one afternoon, and Conner just smiled faintly without explaining. Lois scolded Jon for making fun, and Clark had said nothing — though the name stuck in his mind.
The Gotham shirt.
At dinner, Clark’s eyes often drifted toward it — the faint scent of smoke that clung to Conner’s skin, the way his fingers absently tugged at the cuff when he was thinking. It shouldn’t matter, Clark told himself. But the sight carried a quiet ache, something sharp and wordless that sat between love and envy.
Sometimes Lois caught the expression flickering across his face and gave him that look — the one that saw right through him.
“You’re overthinking again,” she said softly one night as they cleaned the dishes.
Clark smiled, embarrassed. “Am I that obvious?”
“Only to me.” She rinsed a glass, eyes glinting. “You used to hover the same way over Jon’s baby crib.”
He huffed a laugh, low and self-conscious. “That was different.”
“Was it?”
Her tone wasn’t accusing, just gentle — the way sunlight rests on water.
“You can’t make up for lost years by folding blankets tighter, Clark,” she said. “He’s not a nestling. He’s trying to figure out how to belong.”
He dried his hands, staring at the reflection in the kitchen window — the faint blur of Conner in the living room, sitting cross-legged on the floor while Jon showed him a Lego set.
They looked peaceful. But Clark could see it — the hesitation in the way Conner’s hands paused before touching the blocks, as though even the simplest gesture required permission.
“He doesn’t have to try so hard,” Clark murmured.
“Neither do you,” Lois replied.
He didn’t answer. He just watched as Conner leaned slightly closer to Jon, smiling — a real smile this time, small but alive.
For a moment, Clark felt hope bloom in his chest.
Then Conner reached to adjust his sleeve — and the black shirt came into view.
That single image undid all the comfort the moment had offered.
------
Clark excused himself early that night. He didn’t know how to explain to Lois that a piece of fabric could make him feel so small, so displaced in his own home.
Later, lying awake, he listened to the sounds of the house — Lois breathing beside him, Jon’s light snore, the distant hum of the refrigerator — and then, faintly, the door down the hall closing.
Conner’s door.
Clark rose, walked past the quiet hallway, and paused outside his son’s room. Through the thin wooden door, he could hear the soft rustle of cloth — the sound of Conner settling into bed.
For a heartbeat, Clark almost knocked.
Almost.
But instead, he let his senses drift through the room — gently, respectfully. The room was clean, the temperature steady, the sheets unused. And there, near the bed, that same scent lingered — smoke and cedar, the faint trace of Gotham rain.
Bruce.
Clark closed his eyes. The ache that followed wasn’t simple jealousy; it was something more primitive, more painful. It was the Kryptonian part of him — the part that understood what scent meant.
It wasn’t just memory. It was imprinting. Comfort.
Safety.
Conner was nesting, just as Kryptonian children did. Only he didn’t know it — and the scent he had chosen to hold onto was not his father’s.
Clark stepped back, quiet as the night, and returned to his room. He lay awake for hours, listening to the hum of the city beyond the windows, trying not to think about the old black shirt that smelled of another man’s warmth.
But the thought refused to leave.
It clung to him, as persistent as love itself.
------
Dinner at the Kent household was usually warm, in its quiet and human way — the smell of Lois’s cooking, Jon’s chatter filling the air, the hum of conversation softening the edges of the day. But tonight, beneath the golden light and the clinking of silverware, the air felt fragile.
Conner sat across from Clark, posture straight, polite, a guest in his own home. He said little. The glow of the kitchen lights brushed the faint shadows under his eyes. Lois asked about his patrol shifts, Jon talked about school, and Clark nodded when spoken to — but his mind was elsewhere, orbiting around a single object folded neatly on a shelf upstairs.
The black shirt.
Bruce’s shirt. Still smelling faintly of old leather, metal, and cologne.
It had haunted Clark for weeks.
He told himself it was ridiculous — that he was a grown man, that his son was safe, that none of it mattered. And yet… the sight of Conner wearing that shirt, the way he touched its hem absentmindedly, like one might touch a rosary or a talisman — it crawled under Clark’s skin.
He waited until Lois and Jon were distracted. Then he asked, lightly, too lightly.
“Hey, Conner,” Clark began, feigning casualness. “You wear that black shirt a lot. It looks… worn. Is it still holding up alright?”
Conner looked up. His fork paused midair. A flicker of something — wariness — crossed his eyes.
“It’s fine,” he said after a beat. “Still fits.”
Clark smiled, gentle.
“If it’s old, I could get you a new one. Maybe you should throw it aw—”
“No.”
The word came faster than either of them expected. It wasn’t loud, but it cut through the air like a blade.
Jon went quiet. Lois’s eyes darted between them.
Conner took a slow breath, steadying himself.
“Bruce gave it to me,” he said, tone measured but tight. “When he found me. It’s mine.”
Clark blinked.
“I didn’t realize it was—”
“It was the first thing I ever wore after Cadmus,” Conner interrupted, his voice low, controlled. “It’s… personal.”
A heartbeat of silence stretched. Clark’s throat went dry. He forced a nod and smiled — too stiff, too polite.
“Of course,” he said softly. “I just didn’t know.”
Dinner carried on. Lois laughed at something Jon said, but Clark didn’t hear a word. Across the table, Conner’s shoulders had tensed — defensive, guarded, the walls slamming back into place.
------
The next morning, Metropolis was wrapped in sunlight, all glass and silver. Conner had gone out early, patrol shift with the team. The house was quiet — too quiet.
Clark stood in the doorway of Conner’s room. The black shirt was there, lying across the chair, faintly rumpled. His gaze lingered on it, on the faint trace of Bruce that clung stubbornly to the fabric.
It wasn’t rational. It wasn’t heroic.
It was jealousy — raw, stupid, human jealousy.
Before he could think, he picked it up, bundled it with the rest of the laundry, and tossed it into the washing machine. He told himself it was time, that the scent was old anyway, that he was helping. But deep down he knew exactly what he was doing.
He listened to the cycle start, the hum of water filling the drum, and for a fleeting moment he felt something like triumph — and shame immediately after.
------
Conner came home that afternoon. His steps quickened the moment he noticed the faint smell of detergent in his room.
He froze.
The chair was empty. The shirt — clean, wrong, scentless — was folded neatly on his bed.
He stormed downstairs.
“Did you wash my clothes?”
Clark looked up from the living room couch, startled.
“Yeah, I— I threw in a load this morning. You had some laundry piling up, so I thought I’d help.”
“You touched my stuff?” Conner’s voice trembled with anger, disbelief.
Clark stood, palms open.
“Conner, it’s just laundry. I didn’t mean anything by it.”
“You didn’t mean anything?” His voice broke — quiet but seething. “You had no right.”
“Conner—”
“That shirt was—” He stopped himself, fists curling. “Forget it.”
“Conner, I didn’t know it would—”
“Yes, you did!” Conner snapped, eyes burning now. “You knew what it meant to me, and you did it anyway.”
The silence afterward was deafening.
Clark took a hesitant step forward.
“I just wanted to help—”
Conner shook his head, jaw clenched.
“You don’t touch it again. Ever. Do you understand?”
And then he turned and left — out the door, out into the fading light, leaving the air cold and hollow in his wake.
Clark stood frozen in the middle of the living room. The washing machine hummed faintly in the background, a cruel echo.
He had drawn a line where he never meant to. And over something as simple, as devastating, as a shirt.
------
Weeks passed.
The silence between them became a presence in the house — invisible, suffocating, like gravity itself had thickened.
Clark still made breakfast in the mornings. Conner still sat at the same table. They exchanged the same polite greetings, the same hollow small talk about weather or missions. Jon tried to fill the gaps with jokes; Lois gave Clark the kind of worried glance that said fix this, but he didn’t know how.
Every time Clark looked at Conner — at the boy’s slouched shoulders, his careful avoidance of eye contact — guilt hit him like radiation under his skin. The shirt was gone from the chair now; Clark didn’t know where Conner kept it, but he knew it still existed. He could sense its absence, and what it meant.
He had washed away something sacred.
And no apology could bring it back.
------
The Watchtower was orbiting over the Pacific when Clark’s thoughts drifted again.
A Justice League meeting, one of many. The holographic display glowed blue across the round table — tactical updates, supply lines, meteor tracking, the usual rhythm of duty. Clark sat in his seat, eyes fixed on the projections, but his mind was elsewhere — on the dinner silences, on Conner’s clenched jaw, on the sound of that single word: Ever.
He didn’t notice Diana pause mid-report.
Didn’t see J’onn glance at him with concern.
Only when the meeting ended and the others filtered out did Bruce stay behind, arms crossed, the faint clink of his gauntlet echoing.
“You’ve been off lately,” Bruce said. “Distracted.”
Clark gave a half-smile that didn’t reach his eyes. “Long days.”
Bruce’s gaze didn’t waver.
For a moment, Clark wanted to shrug it off. But the weight in his chest was too heavy to carry alone anymore. He exhaled, slow and shaky, the admission clawing its way out.
“It’s Conner,” he said quietly. “I— found something in his room. A shirt. Yours.”
Bruce frowned. “Mine?”
Clark nodded.
“He said you gave it to him after Cadmus. He… kept it. Slept with it. Like it was…” He hesitated, searching for words that felt too raw to speak. “Like it was you.”
Bruce said nothing at first. The silence stretched between them, uncomfortable but not cold. Then, finally—
“I didn’t know,” Bruce said simply. “He was shivering when I found him. I handed him the first thing I had in the car. It wasn’t supposed to mean anything.”
Clark gave a soft, humorless laugh. “Well, it did.”
Bruce studied him. “And you couldn’t leave it alone.”
Clark met his eyes.
“I washed it.”
That, more than anything, made Bruce’s brow crease — not in judgment, but recognition. The kind of mistake only a parent could understand.
“You washed it,” Bruce repeated quietly.
Clark nodded. “It smelled like you. And I—” He swallowed. “I hated that it brought him comfort more than I did.”
For once, Bruce didn’t lecture. Didn’t sigh. He just looked at Clark — the same way he had once looked at Dick, Jason, Tim — the look of someone who had been there before, in his own way.
“He’s half Kryptonian,” Bruce said finally. “But he’s also half human. You can’t reach him with instinct alone. You have to reach him with words and actions.”
Clark frowned. “Instinct is how we— how I build bonds. Kryptonians nest, we create environments of safety, of belonging. I did that for Jon, and it worked.”
“Because Jon grew up knowing you,” Bruce said. “Conner didn’t. He never had that foundation. You can’t expect him to respond to something he was never taught.”
Clark’s eyes fell to the floor. The truth stung.
Bruce stepped closer, voice low but firm. “You want to connect with him? Stop building a nest. Start building trust. Start with a real conversation.”
Clark let out a quiet breath. “You make it sound easy.”
Bruce’s mouth twitched — the closest thing he ever had to a smile.
“It never is.”
------
That night, Metropolis was quiet beneath the stars. Clark flew home slow, carrying the conversation like a weight in his chest.
He hovered outside Conner’s window for a long time before landing. The light inside was off, but he could hear the faint rhythm of Conner’s heartbeat — steady, distant.
He didn’t go in.
Not yet.
He just stood there, on the porch, hands in his pockets, watching the night breathe around him.
There would be a time for words. For rebuilding.
But tonight, Clark let himself feel it — the ache of jealousy, the sting of failure, and beneath it all, something deeper and far more fragile: the hope that maybe, just maybe, Conner would let him try again.
------
The city slept in a hush of silver and glass.
From the Kent apartment, the hum of traffic below sounded like a heartbeat — steady, far away, almost comforting. Clark stood in the hallway, his hand resting against the frame of Conner’s door.
Inside, there was only the faint sound of movement — the rustle of fabric, the sigh of someone trying not to think too hard.
For days, Clark had rehearsed this. All the ways to start, all the sentences that might matter. None of them felt right. Words had never been his problem; silence was. But with Conner, words often made things worse.
He knocked once.
No answer.
He pushed the door open gently.
Conner sat by the window, half-lit by the neon bleed of the city. He wasn’t wearing the shirt, but it lay folded on the nightstand. The fabric had faded even more now — frayed at the collar, softened by years of touch and care.
Clark stood there, unsure if he was welcome. Conner didn’t look up.
“Lois says you skipped dinner,” Clark began softly. “She saved you a plate.”
“I wasn’t hungry,” Conner murmured.
Clark nodded. “Okay.”
The silence stretched, awkward but not sharp. The kind of silence that still had room to breathe, if either of them dared to.
Clark stepped forward, eyes on the shirt.
“I shouldn’t have touched it,” he said quietly. “Back then.”
Conner’s gaze flickered, guarded.
Clark continued, voice low, almost a confession.
“Where I come from… we have this instinct. To build things for our children. A nest. A space that smells like us, feels like safety. I thought if I gave you enough of that, you’d know you belonged.”
He paused. “But I was wrong. You didn’t need a nest. You needed to be heard.”
Conner’s hands tightened slightly in his lap. His voice came after a long beat — rough around the edges.
“I didn’t mean to… make it weird. The shirt, I mean. It’s just— I didn’t have anything. Bruce gave it to me when I didn’t even know who I was yet.”
Clark’s throat ached. “I know.”
“I’m not… replacing you.”
The words were quiet, but they hit like a sunrise after weeks of rain.
Clark took a breath, stepped closer. The air between them shifted — still fragile, but warmer. He reached behind him, pulling out a soft, worn flannel — red and tan, faded from years of work and weather.
“This one’s mine,” he said. “It’s seen better days. But it’s warm. Smells like coffee and hay and maybe too much ink from the Planet’s office.”
He smiled faintly. “If you want it… it’s yours.”
Conner hesitated. For a moment, Clark thought he might refuse — too much pride, too many bruises left from the fight. But then, without a word, Conner reached out and took it.
Clark exhaled slowly, something unclenching deep inside his chest.
He didn’t say anything else. He just nodded, left the room quietly, and closed the door halfway — not a boundary, not yet an invitation. Just enough space for light to spill through.
------
Morning came soft and gold.
Lois moved around the kitchen, humming under her breath; Jon was already halfway through his cereal. The smell of pancakes lingered in the air when Conner appeared in the doorway.
Clark looked up — and froze for just a second.
Conner was wearing both. Bruce’s black shirt underneath, and Clark’s flannel over it, sleeves rolled, collar uneven.
He mumbled a sleepy “morning” before sitting down, reaching for the orange juice like nothing had changed.
But something had.
Clark didn’t say a word — didn’t need to. His chest felt too full, too fragile, like the smallest sound might break it open.
It wasn’t forgiveness. Not yet.
But it was something like home.
And that, for now, was enough.
