Thornton was nerrrrvous. This was his first, proper, not adult-heavy birthday party. And he had no idea what to expect, especially given that there was a theme. He'd never dressed up - Halloween had been a shock and then History of Magic just added to it - and superheroes were completely foreign to him.

So he'd hit the muggle studies section of the library.

He'd had no idea there were so many!! He'd gone back and forth about who he could be and what sort of costume he could manage without buying something or destroying something, either of which would sorely disappoint his parents. So being anyone recognizable was out of the question.

Arriving at the party, Thornton had a piece of purple cloth with two eye holes cut out, tied round his head, an extra large yellow towel tied round his neck like a cape, his winter gloves and boots, and a paper lightening bolt taped to the front of his purple teeshirt.

Entering the treehouse timidly, Thornton looked around. Superheros don't reveal their real identities Huh. Maybe no one would know it was him...
