The world had narrowed to the space where his hand met her cheek. The hum of the Vault, the cold of the dungeon, the weight of the past weeks—it all faded into a distant hum, secondary to the warmth of his skin against hers. He was looking at her as if he were seeing her for the first time, or perhaps, truly seeing her for the last time, without any filters left.
Slowly, as if afraid any sudden movement would shatter the moment, his other hand came up to cradle her face. His thumbs traced the arches of her cheekbones, his gaze following the path of his touch with a reverence that made her heart ache.
"I have," he began, his voice a low, rough scrape, "wanted to do that since the first time you corrected my arithmantic calculations."
A watery laugh escaped her, the sound trembling with relief and a dizzying joy. "You were insufferable."
"You were magnificent," he countered, his eyes finally meeting hers again, blazing with a sincerity that left no room for doubt. "A brilliant, infuriating, magnificent whirlwind. You still are."
He leaned in, his forehead coming to rest against hers. It was an intimate, grounding gesture. She could feel the faint coolness of his skin, the soft whisper of his breath, the thrum of his magic so close to her own. She closed her eyes, breathing him in—the scent of ozone, old books, and now, something uniquely, essentially him.
"I am sorry, Cassian," she whispered into the small space between them. "For what I said. I didn't mean it. Not any of it."
"I know," he murmured. "And I'm sorry for pushing you. For assuming the worst. For running." He pulled back just enough to look at her, his expression serious. "It's what I do. When things get… complicated."
"Well, get used to complicated," she said, a genuine smile finally breaking through. "Because I'm fairly certain this is just the beginning."
A real, unguarded smile transformed his face, the sight so breathtaking it made her chest tight. "I'm counting on it."
He didn't kiss her. Not then. The moment felt too large for that, too significant. Instead, he took her hand, lacing his fingers through hers, and led her to the stone bench. They sat, shoulders and knees touching, his hand still firmly holding hers as if he was afraid she might vanish.
They talked. Not about the Vault, or the book, or the Ministry. They talked about everything else. He told her about growing up as an only child in a quiet, remote wizarding household, his parents—academics who were more comfortable with runes than with people. She told him about her parents, the dentists, and the profound, lonely shock of discovering she was a witch. He confessed his childhood habit of accidentally enchanting the family portraits to argue magical theory with him. She made him laugh, a real, deep, wonderful sound, with a story about the time she'd set Snape's robes on fire.
The hours slipped away. The single blue orb began to dim with the approach of dawn, casting the chamber in a soft, pre-dawn grey.
"We should go," Hermione said softly, though she made no move to get up. "Before the castle wakes up."
Cassian nodded, his thumb stroking the back of her hand. "There's… something I need to show you. Something I've been working on since I left. It's why I was at the Department of Mysteries."
Her curiosity, ever-present, sparked. "What is it?"
"A theory. About the Vault. And the book." He stood, pulling her up with him. "But it can wait. This…" He looked down at their joined hands, then back at her face. "…this was more important."
He walked her to the Apparition point in the courtyard, the first hints of pink and gold staining the horizon. The air was cold and clean, smelling of damp grass and new beginnings.
"Can I see you tonight?" he asked, his tone hesitant, so unlike his usual confidence. It was endearing.
"Yes," she said, her smile feeling like it would permanently etch itself onto her face. "I'd like that."
He nodded, a slow, happy smile of his own spreading across his face. He lifted her hand to his lips and pressed a soft, lingering kiss to her knuckles. The gesture was old-fashioned and utterly sincere, sending a shiver up her arm.
"Until tonight, Hermione."
He Disapparated with a soft crack, leaving her standing alone in the dawn.
She looked down at her hand, the ghost of his kiss still tingling on her skin. The hollow ache of the past weeks was gone, replaced by a warm, humming fullness. The foundation they had built for their work had been shattered, but in its place, they had laid the first stones of something else. Something personal. Something fragile and strong and terrifyingly, wonderfully real.
The war was long over. The battle for the Vault was, for now, won. But as she turned to Apparate home, her heart lighter than it had been in years, Hermione Granger knew that her greatest adventure was only just beginning.
