Harry leaned into the hug, pressing his face against Roger's neck with the excuse that the height difference put it at just the right angle. If he happened to get a good whiff of Roger's particular scent, well, that was between him and the late-night fantasies that he definitely didn't have.
"Hey," he said back, voice muffled a bit by Roger's shoulder. And then Roger was pulling away, and Harry tried not to feel too sad about it. He nodded, and if he stood a little too close as they Apparated, well, he didn't want to be Splinched now, did he? He kept his hold on Roger rather longer than necessary after they reappeared, but in his defense he always felt a little shaky after Side-Along when he wasn't the one Apparating. Eventually he had to let go.
"Nice day for Quidditch," he commented as they went through the line to get in.
