While he's always seen following around Sy, a Jerk Jock, Reid himself is more of a Jerk With a Heart of Gold. Reid and Sy are Fire Forged Friends who irritated one another until Sy became captain. His talent in Transfiguration implies he's Brilliant But Lazy, and plays dumb sometimes to get out of doing anything he deems too difficult. On the Quidditch team, he's not easy for his captain to handle, but when it comes to being a Seeker, he's ridiculously good, and Sy just kinda has to deal with it.

Reid indulges in lots of Heroic Self Deprecation, but deep down he's a Wide-Eyed Idealist. All the same, his opinion on being a prefect is that Being Good Sucks.
Also, parkour and swans. Reid thinks he suffers from a little swan-brain even as a human. He might be imagining it.
