Sirius grinned as the cool breeze drifted through the courtyard. He had school books sitting beside him, clearly waiting to be read and used properly. Instead, they were just paperweights for parchment that he wasn't paying attention to currently. The dark haired teen was scratching away at a bit of paper in his hand, quill scrawling across it quickly. Any other student passing by could make a guess at what he was doing, but he doubted that they would be right.

Certainly no one would think that he was doing school work, no matter how many feet he needed for an essay. That would be done in the dead of night when no one else was looking. Only the other Marauders knew how and when he got his school work done. It impressed the teachers that he even handed anything in, and the other students around him were shocked that he had the capacity to get it done.

He was intent on scribbling down all the ideas in his head. There was a mess of things floating through his mind and not all of it was devoted to pranks to be pulled. He was so engulfed in the task at hand that he barely noticed that lessons were ending or students were finding their way around the castle without others knowing. Even those sneaking around wouldn't care if this particular Black saw them as he was more often than not getting into trouble himself. If he was around, they would be a lot safer from getting detention.
