Sirius / Remus dranks.
It was true, Sirius was loyal to a fault. It was really something of a wonder that he hadn't ended up in Hufflepuff. It probably would have been a nice stint right there next to the kitchens. But no, his reckless nature and acting-before-thinking attitude had trumped most anything else. Well, that and the fact that he'd been brave enough to defy his family completely by not wanting anything to do with the Slytherin title.
It'd worked out well, anyway. He'd met and kept his very best friends in shared rooms and next to a roaring fireplace. Hogwarts had been a much simpler time, even when he'd been making mistakes.
Sirius liked it when Remus did that thing -- smiled in a way that was practically sharp, a little predatory. It suited him, even if it was a look that rarely came out. He liked it more that it mostly came out for him. "Well," he said, taking another drink to slow his words, "fancy meeting you here, then. I reckon we could find some way to sate all that curiosity if we try hard enough?"
