His eyes flickered down to where her hand had been on his arm a moment earlier, and he nodded, taking it perfectly in stride - it felt less surprising than it should have, somehow - and left the Hall, heading in the opposite direction to sweep a few of the more traveled corridors. His mind was a mess tonight, strewn with so many different unconnected old feelings, that he had little opportunity to dwell at all.
But really, he thought it was a genuinely good idea. The only reasons it might not have been - that his job demanded something else of him and he wasn't in the habit of letting people know him at all - were laughably unpersuasive. He had never cared much about the former, and the latter was ... less than attractive, tonight. It was without very much anxiety that he made his way down toward the kitchens and the Hufflepuff common room, where he assumed he'd find her.
