It was supposed to be a normal summer in London—sticky air, late nights, everyone pretending they had nothing better to do before term started again. Lily, Marlene, Mary, Dorcas, and Alice had dragged the Marauders out for a concert “just for fun.” Sirius insisted on getting them in through the back. James called it illegal. Remus called it predictable. Sirius called it character development. They sneaked in anyway. At first, it was just noise and lights and a singer they didn’t really know—until a few songs in, when something shifted. The voice hit a certain note, and the whole stage seemed to tilt into something sharper, more controlled, almost familiar in a way that didn’t make sense. Sirius went very still. “…No,” James said slowly. “That can’t be—” But it was. Celeste. Not Celeste the myth people whispered about in magazines or radios—but the girl from Hogwarts. The one who sat too quietly in Slytherin robes like she wasn’t already someone else entirely. By the time the set ended, none of them were looking at the stage the same way anymore. And none of them said it out loud on the way out. Because first day back at Hogwarts was next week. And now they all knew exactly who they might be sharing the castle with.
