"So..." Sirius crawled behind the curtains that this kid had drawn all around his bed, not seeing them as the obvious 'stay out' sign that they were. He heard James talking to Peter, but he was on the second part of the mission. Befriending this kid.

Trouble was that he had no idea how to go about it. He didn't even know his name, because during the sorting he had been too distracted by the impending doom unfolding in front of him, given he had been one of the first to be sorted, sitting down at the Gryffindor table to be welcomed by icy looks all around.

Things had thawed once James was there. And now he had to break the ice here too. "I'm Sirius."

Wait. "I mean, I'm pretty funny actually. But I'm called Sirius."
