The castle was quiet.
Sirius had done his usual rounds. Corvus and Rigel first. Rigel had finally loosened his grip somewhere between the corridor and the family wing, had allowed himself to be carried, had fallen asleep with the heaviness of a child whose body had spent everything it had and had nothing left for staying awake. He was asleep now with one hand still loosely fisted in the fabric of his blanket, as though some part of him had not entirely let go. Corvus was beside him, close in the way they were always close, blonde curls against the pillow.
Lyra was in her own room. The compass was on the bedside table where it always was. Her breathing was deep and even and entirely untroubled, which was its own kind of relief. She had come back to herself in the corridor. Lyra not asking questions was the most alarming thing about the evening in its own way. He had tucked her in and stood there longer than he needed to.
Alphard had been asleep before they reached his room.
Now Sirius stood in the corridor outside Esme's door.
He had been standing here for longer than he would have admitted to anyone. Not pacing. Just standing, one hand raised, not quite knocking.
The light under the door told him she was awake. It was late — past midnight, the veil thickened again, the night finally and completely itself rather than something else — and the light was still on and he knew she was in there and he knew what tonight had been for her and he was standing in the corridor outside her door with his hand raised and not knocking.
He knew what the children needed when they were frightened. He had learned that, slowly and carefully, over the past months. What Rigel needed, what Corvus needed, what Lyra needed and what Alphard needed and how each of them was different. He had gotten reasonably good at comforting the children.
He was considerably less certain what Esme needed.
She was not a person who announced distress. She was not a person who asked for things easily. She was a person who processed in private and presented the finished version to the world, and he had learned to read the gap between what she showed and what it was costing her but reading it and knowing what to do about it were not the same thing.
She had spoken to her mother tonight. Through their four-year-old daughter's body, in a cold corridor with the darkness moving around them and the wind coming from nowhere. She had heard her mother's voice for the first time in years.
Sirius did not know what to do with that. He was not certain anyone did.
He knocked.
A brief silence. Long enough that he wondered if she was asleep after all, if the light under the door was simply a lamp left burning, if he should—
"Entrez," she said.
He opened the door.
She was on the bed. Not under the covers, and still in the clothes she had been wearing since before the corridor, lying on her side with her back to the door, her hair loose across the pillow. The lamp on the bedside table was lit. The nigella on the windowsill caught the light.
Sirius stood in the doorway for a moment.
He knew her habits. He knew that Esme changed before she rested, always, that she was particular about it in the way she was particular about most things, that the ritual of it was part of how she closed one part of the day and moved into the next. He had never seen her forgo it.
She had not moved since he opened the door.
She still hadn't moved.
The silence stretched between them.
"Are the children all right?" Esme asked quietly.
Sirius nodded, a reflex even though she wasn't looking at him. "Yes. Rigel finally calmed down. Lyra's breathing is steady; I checked twice."
He watched as the rigid line of Esme's shoulders finally dropped, a fraction of the tension draining out of her.
"Good," she said. She still didn't move.
There was more silence, heavy and thick with the ghosts of the corridor.
"Do you want to talk about it?"
The silence stretched long enough that he thought she wasn't going to answer.
"She called me mon trésor," Esme said.
She still had not turned toward him.
"She always called me that," she said. "From when I was very small. I thought I remembered what it sounded like." A beat of heavy silence passed. "I had forgotten. I did not know I had forgotten until I heard it again."
Sirius said nothing. He simply listened, refusing to crowd the space, offering her his absolute presence.
"I just... I didn't expect her to be so angry," Esme murmured.
"I didn't entirely understand the context," Sirius said gently, leaning forward a fraction. "But why was she so furious that you were married to me?"
"I don't know," Esme answered, her brow furrowing in the dim light. "She seemed to think that he set it up. That he forced me into it."
"He?"
"I think it's my father."
It was then that Esme finally turned to him. As her gaze met his, a new, chilling realization seemed to dawn in her eyes. For the first time, she looked at the jagged pieces of her past and saw a larger, uglier picture. There had to be more to why her parents had separated. Why they had lived apart for so long without ever divorcing. There must have been some sort of hidden agreement regarding her, and whatever it was, it was the catalyst for her mother's centuries-old fury.
"My mother kept a promise," Esme said. "Whatever happened between them — and something happened, I am certain of it now — she kept it to her grave. She did not tell me. She came through tonight and she still did not tell me." A pause. "Which means the answer is not on her side."
Sirius watched her face. "So, you're going to confront your father?"
Esme looked at the ceiling for a moment longer. Then, in the tone she used for things she had already decided.
"Oui," she said. "Je pense que oui." Esme looked away, her posture stiffening again. She wanted answers—the need to know the truth was already gnawing at her but the thought of meeting with her father filled her with a deep, cold discomfort.
"Do you want me and the children to come with you?" Sirius asked.
Esme turned her head back, giving him a wry, humorless look. "I do not think Arcturus would be particularly happy if the Malfoys met the children before he did."
"Ah."
The realization hit Sirius with a physical thud. He would never hear the end of it from the old man if that happened. And knowing his family, Arcturus would absolutely find out about it, one way or another.
"Besides," Esme added, her voice dropping to a steadier register, "I think this is something I should do alone."
"Well," Sirius said softly, reaching out to place a comforting hand near hers on the mattress, "if you are sure."
"Hmmm." Esme hummed.
The silence settled between them, not uncomfortable. Her hand still against his on the mattress, neither of them having moved.
"We have to think about the children," Esme said.
"We do," Sirius agreed.
"Lyra." She said the name with the weight of a problem she had already begun turning over. "Being a medium — it is not something I know well. I have read about it. Portia had manuscripts in the family library, some of them very old, and I went through them when I was young because Portia thought I should understand what the Peverell connection to death actually meant in practice." She paused. "The only medium I know of with any living reputation is the head of the Laveau family. I have never met them."
"Is that — a wizarding family?"
"Old. Very old. French Creole in origin, though the family has spread considerably." Esme's voice had taken on the tone she used when she was pulling from memory rather than speaking from experience. "They have a long relationship with mediumship. It is their family gift the way — the way the Black gift is the Metamorphmagus ability." A pause. "If anyone would know how to help Lyra understand what she is, it would be them."
Sirius looked at the ceiling. "I'll reach out. I know people who know people — someone in the ICW network will have a connection." He paused. "She's so young. The thought of her carrying this without anyone who understands it—"
"She is not carrying it yet," Esme said. "Tonight was the first time it broke through properly. She does not understand what happened to her. We have time to find the right people before she needs to."
"Not much time," Sirius said. "If it broke through on Samhain it will break through again. The leyline is active now. The veil thins four times a year. It is just thinnest during Samhain."
Esme was quiet, acknowledging this.
"She removed her mask," Esme said.
Sirius turned his head toward her.
"During the bonfire walk." Esme's voice was even. The tone of someone stating a conclusion they had reached some time ago and had been sitting with since. "She must have removed her mask at some point." A pause. "I don't think it was off for more than a few seconds. But the cleansing is when the spirits are most active — when the veil is thinnest and they are looking for ways through. It is why the masks exist. To confuse them. To make the living unrecognizable." She looked at the ceiling. "Without it, even for a moment, she was visible. And she is — what she is. A door. They would have found her the moment she opened it."
Sirius was quiet.
"It is not her fault," Esme said. "She is four years old. She didn't know." Another pause, shorter. "I should have anticipated it. I should have—"
"Esme." His hand turned slightly against hers. "You couldn't have known she would do it. You couldn't have known what she was. Both of us couldn't have known."
"No," Esme said. "But I know now."
The implication was clear. Next Samhain, next Imbolc, next threshold night — she would know. The masks would be secured differently. Lyra would be watched more closely, or kept inside, or managed in some way that Esme had not yet decided but would decide before the next time the veil thinned.
She was already solving the next problem. That was Esme.
"It wasn't your fault either," Sirius said quietly.
A long pause.
"Je sais," she said. And then, slightly wry, slightly dry, the composure returning in the way it returned when she had decided to stop sitting in something: "That does not make it less annoying."
"There is also Alphard." Sirius said.
A beat of silence that had a different quality to it — the silence of two people who had been carefully not thinking about something and had now agreed to think about it.
"A Metamorphmagus manifesting at two years old," Esme said. "It is — early. Earlier than any case I have read about. The ability usually surfaces around four or five when the child has enough conscious sense of self to trigger it." She paused. "Which suggests his is not triggered by conscious thought. It is entirely instinctive. He saw Nymphadora change and his body simply — followed."
"Which means it will happen again," Sirius said. "Without warning. In front of people."
"Yes."
"The Ministry."
"Yes," Esme said again, quieter.
Sirius stared at the ceiling. The Ministry's relationship with rare gifts was something he had spent the better part of September thinking about on Andromeda's behalf, and now it had arrived inside his own house in the form of a two-year-old with pink cat ears. Nymphadora had at least had eleven years before registration became a concern. Alphard had considerably less time than that if his ability kept manifesting.
"It speeds things up," he said.
Esme didn't ask what he meant. "The headship."
"The headship," he confirmed. "The protection it provides. The standing. If the Ministry comes looking at this family—" He stopped. Thought about Lyra and what a medium meant to people who studied and catalogued and used rare gifts. Thought about Alphard. Thought about Rigel and Corvus. "We need to be the kind of family they cannot simply approach without consequence."
"You were already planning to take it," Esme said.
"I was planning to take it eventually. I am now planning to take it soon." He paused. "I need to talk to a lot of people. People who understand what these gifts mean practically, what the implications are, who to watch out for." He looked at the window. "And I need to learn more about ancient magic."
Esme turned her head slightly toward him. "Rigel."
"What I saw tonight was not — it was not what I have been seeing for the past few months. The wisps have been silver and white. Old and settled. What came from Rigel was gold." He said it carefully, the way he said things he hadn't finished understanding yet. "Different. Stronger, I think. And I don't know what that means and I need to know what that means."
"Portia's library," Esme said. "There is more in it than just the mediumship manuscripts. The Peverells studied ancient magic extensively. If there is an answer about what Rigel carries it may be in there."
"Then we go to Germany."
"Eventually. Right now, it won't open for us and Lyra is too young. Ragnok has advised against it until she is seven years old." Esme said.
"I guess we have to wait." Sirius said.
The lamp burned lower. The sea moved outside, steady and unchanging. The castle was quiet around them. The children asleep, the leyline settled back into its low hum beneath the stone, the night finally and completely ordinary again.
Sirius meant to say something else. Something about the headship timeline, or Portia's library, or the Laveau family, or any of the things that were waiting on the other side of tonight to be dealt with.
He didn't say it.
The ceiling was very still. Esme's hand was warm against his. The lamp guttered once and steadied.
Somewhere between one breath and the next, the conversation simply — stopped.
Neither of them noticed when it did.
