Quidditch was a good thing for Nat. It was the second best thing, after potions, for occupying his otherwise far too busy brain. It helped him focus. It helped him clear his thoughts. But when practice was over and the lights were off it was harder to focus anymore, and his busy thoughts and the conflicting emotions that came with them pushed their way back in. He was headed in to the castle when he saw the sparks by the Slytherin locker room. His curiosity got the better of him.

Climbing the bleachers he found Pete charming things and throwing them. "You know, You could catch the pitch on fire like that. Pretty sure that would make us forfeit to Hufflepuff." And that was not happening on Nat's watch. They were going to beat Hufflepuff, even if Pete's girlfriend was on the other team. End of discussion. 

Nat pulled a lose scrap of paper with doodles of birds and palm trees that he'd done during Muggle Studies out of his bag. Crumpling it, he charmed it and tossed it towards the Slytherin Locker room too. Exploding was a good stress release, he supposed. Not as good as aggressively chopping potion ingredients in to minuscule pieces. In Nat's opinion anything to do with potions would always win. But exploding was pretty cool too.
