Apollo Zabini, Slytherin Keeper extraordinaire, had turned into a determined recluse. And the library had become his place of residence, so to speak. It was quiet, nobody asked him what he was writing - as Naomi did when he spent time in the study room with her. Merlin, that girl was a piece of work. But she and Aleksa were his only friends, at that point. So he would just deal with that.
But today he actually had work that he could do rather than writing some pondering or other to Lily. Not that she would mind, or that he didn't enjoy it. But he did need to reorganize his priorities, as she'd said the last time he saw her alone. School work had fallen off at one point, but he only went to his apprenticeship, now, when the Minister of Magic needed his help. And Apollo was still, endlessly shocked by that. But it was wonderful and he would never complain.
So, anyway, he had time. He was still curious about the potion that he'd made to save the Minister's hand that first day. So when he finished his Charms work, he went in search of a book that might list it. Before he checked the restricted section, he sought out the general potions aisles. Side-stepping one of the tables nestled between the sections, he began browsing, and selected one as he came up alongside the table of a younger Gryffindor.
Apollo glanced the boy's way, but wasn't sure that he recognized him, so he stayed standing rather than asking if he could sit and join them. Whoever the kid was, he'd undoubtedly heard the rumors about the horrible Slytherin bloke in sixth year. Right? So what was the point in trying to be friendly?
