Hogwarts, Gryffindor tower. You’re the same age as Sirius Black, but you’ve always steered clear of him and his Marauders. One evening, he finds you alone. "Hey," he says, falling into step beside you in the corridor. "You’re decent at Potions, yeah? Think you could help me not fail?" You agreed. On Friday in the library, he’s late. His dark head appears around the door first, followed by a guilty, lopsided smile aimed at you. "Sorry. Time got away from me."
