It happened on a day so ordinary that for several hours afterward Lily kept trying to force it back into ordinariness by talking around it.
That was how Severus would remember it later. Not the weather first. Not the lane or the wall or the exact shape of Petunia's face. The talking. Lily's voice too quick, too bright, moving around the thing as if speed alone might keep it from settling into its proper meaning.
But before that, it was only afternoon.
A pale one. Warm enough for sleeves pushed up, not warm enough to trust. The kind of day summer made when it had not fully committed to itself. The sky held high white cloud. The street smelled of dust and damp brick and something sweet from a bakery further off toward the high road. School had ended without incident. The mills droned on. Windows were open in patches along Spinner's End, and because of that the row of houses sounded almost more alive than usual, voices and radios and pans crossing the road in loose pieces.
Lily had found him at the corner before he reached home.
Petunia was with her.
That was the first sign the afternoon might go badly.
Petunia had been coming less often lately, which made her presence now feel deliberate. Not because she had chosen joy in the outing. Because she had chosen not to be left out of whatever Lily thought the day might become. She stood with her cardigan buttoned wrong and fixed at once, as though even her own clothes offended her if they slipped from order. Her expression said clearly that she was already tired of the company before it had begun.
"We're not going to the river," she announced before Lily could speak.
Lily frowned. "I hadn't said we were."
"You were going to."
"I wasn't."
"You always are."
Severus looked from one to the other and said nothing.
This, too, had become habit: reading first, speaking later. The sisters' tensions had their own weather systems now. Most of the time Lily walked through them as if under light rain, barely dampened. Petunia carried them like evidence.
Lily turned to Severus. "We can go behind the houses instead."
"Why?"
"Because Tuney says she won't get mud on her shoes."
Petunia said, "Because I don't want my shoes ruined, yes."
"They won't be ruined."
"They always are with you."
The sentence landed with more weight than shoes merited.
Lily rolled her eyes in the direction of the sky and started walking before either of them had properly agreed. Petunia followed because not following would have meant surrender. Severus followed because once the sisters had entered motion, standing still looked stranger than participation.
They went behind the row first, through the narrow cut where broken fence posts leaned into nettles and the ground changed from pavement certainty to dirt threaded with roots. The backs of the houses were worse than the fronts in ways most respectable people preferred not to know. Rusted tins. Sagging lines. Old crates. The smell of damp laundry and ash. Yet the space also felt less watched. Children used it for that reason.
Lily moved ahead.
Petunia moved carefully.
Severus moved with the strange divided attention such places always drew from him, one part on the ground and one on the people in it. He had come to understand by now that Lily's trouble lay not in cruelty but in motion. She reached for whatever caught her first and assumed the world would adjust. Petunia's trouble lay in memory. She retained every slight and every exclusion, then carried them forward until the next small incident had to bear the weight of all the ones before.
He knew this shape.
He did not know yet what to do with it.
The path widened behind the old brick wall where the Evanses' yard ended and waste ground began. Someone had once tipped cinders there and then forgotten the place. Sparse grass had come through anyway. Near the wall grew a tangle of summer weeds and a young hawthorn leaning at the wrong angle because no one had staked it when it first needed it.
Lily stopped at once.
"Oh."
Petunia sighed. "What now."
Lily had found foxgloves.
Not proper garden foxgloves, neat and tended. Wild ones. Tall, extravagant, almost too bright for the place, their purple bells crowding one side of the wall where broken mortar held more soil than sense.
Severus saw them and knew at once what they were.
"Don't touch those," he said.
Lily looked back, surprised. "Why?"
"They're poisonous."
Petunia folded her arms. "Everything's poisonous according to him."
"No, it isn't."
"Yes, it is."
Lily, instead of entering that familiar argument, bent nearer to the flowers without quite touching them. "They're lovely."
"Don't," Severus said again.
She looked over her shoulder. "I'm not."
Petunia came up beside her, unwilling to be excluded even from disobedience. "What happens if you do?"
Severus hesitated.
This was already going wrong.
"Nothing from just touching," he said. "Probably."
Petunia seized at once on the uncertainty. "'Probably.'"
He ignored her.
Lily was still studying the foxgloves. "How do you know?"
"Book."
"That's his answer for everything," Petunia muttered.
"It's a better answer than making things up," he said.
The words escaped sharper than intended.
Petunia's face changed.
Not much. Enough.
Lily straightened at once, hearing the shift if not understanding its future. "We weren't making things up."
Severus looked at the flowers because looking at either sister now would be worse. "I didn't say you were."
Petunia said, "You meant it."
He did not answer.
The afternoon held for one brief second, all three of them arranged around the wall and the purple flowers and the sentence not quite denied.
Then Lily, perhaps feeling the tension and trying to move them past it by force of attention, said, "Look."
She pointed to the highest bell on one stem.
Inside, half-hidden in shadow, a bee had gone deep enough that only its striped middle remained visible. The flower moved faintly with its work.
Lily smiled.
Petunia looked too, but only for a second. Then her eyes moved to Lily's hand.
"Don't."
Lily had lifted her fingers toward the bell, not to crush it, perhaps not even to touch it. Only to look closer.
"I'm not doing anything."
"You are."
"I'm not."
"You always are."
The sentence was too quick, too loaded. It came from somewhere deeper than the flower.
Lily turned. "What's that supposed to mean?"
Petunia flushed. "You know what it means."
"No, I don't."
"Yes, you do."
Severus felt the air alter.
Not the real magical pressure yet. Only the human one that sometimes came before. The sisters stood too close now, one still bright with interest, the other sharpened by something that had been gathering for weeks. The wall behind them held the heat of the day. The foxgloves leaned in their own dangerous beauty. Somewhere beyond the houses a dog barked and was ignored.
Lily's voice changed first.
Not louder. More hurt than confused now. "I only wanted to look."
Petunia laughed once through her nose. "You always only want to look."
That stopped Lily.
The silence after was small and exact.
Severus knew then, with a clarity he did not want, that Petunia was no longer speaking only about flowers or fields or whether she had been dragged along unwillingly. She was speaking of everything Lily had begun to turn toward that Petunia could neither share nor stop. The river. The lane. The questions. The impossible things. The very fact that Lily's attention could move away from her and settle elsewhere without asking.
Lily did not understand this fully.
Not yet.
But she understood enough to hurt.
"What's wrong with you?" she said.
Petunia's face went white and then red so fast it looked painful.
"What's wrong with me?" she repeated.
Severus took one step closer. Not because he had a plan. Because movement sometimes prevented worse movement if timed right.
"Leave it," he said.
Neither sister heard him.
Lily said, "I didn't do anything."
Petunia's voice sharpened into a shape he had never yet heard from her. "That's exactly it."
Lily stared.
Petunia stepped back from the wall.
Her heel found the loose patch of cinders near the edge of the waste ground. Severus saw it the instant before it happened. Saw the bad footing, the narrow drop where old bricks and rubble had been tipped years ago and half-covered by dust and weeds. Saw Petunia's weight shift the wrong way.
He opened his mouth.
At the same moment Lily reached toward her.
Whether to catch her, to stop the quarrel, or simply because Lily always reached first and thought later, Severus never fully knew.
Petunia jerked away from the reaching hand.
Her foot slid.
For one terrible second she did not fall exactly. The world only tilted under her. Arms out. Shoe scraping for ground that gave. The cinders hissed and shifted. Then she went down hard onto one knee and one hand against the broken edge of the tipped rubble.
The cry came after the impact.
Sharp. Real.
Lily gasped and moved at once.
Severus was already there.
Petunia sat in the dirt with one hand pressed to the ground, the other to her knee, face stunned not by pain first but by humiliation arriving through it. Dust had gone up the side of her skirt. One palm was scraped raw. There was a white mark of shock across her mouth before colour came back hard and furious.
"Don't touch me," she snapped, though neither Lily nor Severus had yet reached her.
Lily froze anyway.
"Tuney—"
"Don't call me that."
Her voice broke on the last word.
Severus crouched a little away, close enough to see the damage and far enough not to become part of it unless asked. The scrape on the palm would hurt. The knee might bruise badly. Nothing seemed broken. The cinders had shifted under her in the ordinary way loose cinders did.
And yet.
And yet he had felt something in the moment between slip and impact.
Not the clean wrong-air certainty of the broken window. Not the hot defensive lash of the boy on the corner. But something. A small sudden pressure, badly aimed and overfast, as if two different wants had struck the same second and made the world lurch.
Lily looked from Petunia to the wall and back again, face gone pale. "I was only—"
Petunia turned on her.
"You pushed me."
Lily recoiled as though struck. "I did not."
"You did."
"I didn't!"
Severus heard, under Lily's denial, real fear now. Not fear of punishment. Fear of the possibility itself.
Petunia's eyes were wet but furious. "You did. You always do things."
That sentence changed everything.
Lily stared.
Severus felt the blood go colder in his arms despite the warmth still trapped in the wall behind them.
Petunia was breathing too quickly. Dirt streaked the side of her hand. The scrape had begun to gather bright red through the dust.
Lily said, quieter, "I was trying to help."
Petunia's laugh was ugly with tears. "No one asked you to."
Again, the real quarrel sat below the visible one.
Severus stood because crouching now felt wrong. The whole scene had gone brittle. The foxgloves by the wall seemed almost theatrical in their stillness, purple bells hanging untouched above the mess beneath them.
He said, because someone had to say something not sharpened by sisterhood, "You slipped."
Both girls looked at him.
Petunia's eyes flashed. "I know what happened."
"No," Lily said at once, turning toward him with relief and desperation mixed together, "I think she did. I think the ground—"
Petunia twisted toward her. "Don't."
Lily stopped.
The silence that followed had a new quality.
Not argument now. Division.
Petunia pushed herself up with her uninjured hand, refusing both their help. Her face had set itself around the pain into something colder than before. She looked first at Lily, then at Severus, and in that sequence Severus understood that whatever resentment had been growing in her had just found a harder shape to live in.
Not because she truly knew whether Lily had pushed her.
Because ambiguity was enough. Ambiguity left room for all the other grievances to move in and settle.
"I'm going home," Petunia said.
Lily took one step forward. "Tuney, I didn't—"
Petunia stepped back from her as if from something dangerous in a way that made Lily stop at once.
"You keep away from me."
The words were quiet.
That made them worse.
Then Petunia turned and walked toward the houses, one leg stiff with the bruise already beginning, her back held so straight it looked painful. She did not run. She did not cry again. She only went, carrying the injury like proof.
Lily remained by the wall.
The colour had left her face almost entirely now. She looked younger all at once. Smaller. The hand she had half-lifted toward her sister still hung a little from her side as though the gesture had not fully understood it had failed.
Severus looked at the cinders.
They had shifted. Obviously. Plenty to account for a slip. Yet he could not stop replaying the instant before. Lily's reaching hand. Petunia jerking away. The strange small pressure, not from himself this time, he thought, though thought was the problem. He did not know. That was the whole horror of it.
Magic, when it came tangled with fear and anger and two children already midway through hurting one another, did not arrive with labels.
Lily said, barely above the sound of the mills now coming back into hearing, "I didn't push her."
He looked at her.
She wasn't asking him to fix it. Only to witness the sentence.
"I know," he said.
It was not certainty.
It was the nearest thing he could give that would not wound her more.
Lily looked down at her own hand. Opened it. Closed it. The movement was small and unconscious.
"I just wanted her to stop being cross."
He said nothing.
Because he knew, and did not know, and because the words available to children were not built for this sort of thing.
After a moment Lily rubbed the heel of one hand against her skirt as if trying to erase a sensation from it.
"She'll tell Mum I pushed her."
"Yes."
Lily looked up, startled by the plainness of the answer.
"She will," Severus said again.
The truth of it settled between them.
Lily turned toward the row of houses where Petunia had already vanished inside. Evening had begun lowering itself over Spinner's End without waiting for anyone's quarrels to finish. Windows lit one by one. A radio started. Somewhere a pan lid struck a stove. Ordinary things resumed.
Lily swallowed. "Should I go?"
He knew she was not asking about the path.
"Yes."
She nodded.
They walked back together but not close. The afternoon had altered too much for closeness. At the corner before the Evans house, Lily stopped.
"Do you think I did?"
He looked at her.
No answer here would be clean.
If he said no too quickly, it would sound like comfort and not truth. If he said yes, or even perhaps, he would be placing in her hands something she was already too frightened to hold. If he said he didn't know, that would be the truest answer and the cruelest.
He chose what children often choose when the truth is too jagged to carry whole.
"I think she slipped," he said.
Lily searched his face.
He held still.
At last she nodded once, though he could see she had heard the incompleteness in it.
Then she went in.
Severus crossed the street and entered his own yard with the whole incident still moving in him like unsettled water. His mother was at the sink when he came into the kitchen, sleeves rolled, the steam from the kettle clouding the new pane. She looked over at him.
"You're late."
He set his satchel down.
"Petunia fell."
Eileen's hand stopped on the cup she was rinsing.
"How?"
He looked at the table. At the spoon by the loaf. At the ordinary kitchen objects suddenly made unbearable by their certainty.
"By the wall," he said. "Near the cinders."
His mother turned off the tap.
"That sounds foolish."
"It was."
She watched him for a second longer. "Was it?"
He looked up then.
No one else in the world could make a child feel more seen by using fewer words.
He hesitated.
The pause told her enough.
After a moment she said, "And Lily?"
"She says she didn't push her."
Eileen set the cup down carefully. "But Petunia says she did."
He nodded.
His mother was quiet a long time.
Then: "Did you see?"
Another terrible question with no clean answer.
"Not exactly."
Her gaze stayed on him.
He said, because there was no use pretending less than this, "It felt strange."
Something in her face changed and was controlled at once.
There.
That was the answer.
Not explanation. Not comfort. Recognition.
Eileen dried her hands slowly on the cloth. "Sometimes," she said, "people remember the fear more clearly than the thing itself."
He stared at her.
She went on, still in that same careful practical tone that made the sentence more serious rather than less. "And sometimes something happens in the middle of it that no one can sort after."
He thought of Lily's hand reaching. Petunia pulling away. The slide. The pressure. The impact. The accusation.
"Yes," he said.
His mother looked toward the darkening window. "That may be enough."
Enough for what, he did not ask.
He knew.
Enough for Petunia to harden around it. Enough for Lily to begin fearing a part of herself she had mostly met through flowers and leaves. Enough for one afternoon to divide into before and after without ever producing certainty.
That night, from his bedroom window, he could see the Evanses' front room light on later than usual. Two shadows moved inside. One stiff and sharp. One restless. Once the door between rooms closed harder than necessary. Once a raised voice blurred through brick and distance. Once, unmistakably, Petunia's.
Severus let the curtain fall and went to bed.
Long after, lying in the dark, he still could not decide exactly what had happened by the cinder patch.
Petunia had slipped. That was true.
Lily had reached. That was true.
Something had changed in the moment between those truths. That, too, he could not deny.
But the incident itself would not live afterward as a fact. It would live as versions.
And Petunia's version, he thought as sleep came slowly, was already turning colder than the bruise on her knee.
