If you want, I feel like we should establish stuff with Sokka and Rarity, seeing as how they're both Ravenclaw Fifths. And... Possibly Kowalski and Rarity, too, because Kowalski probably has an interest in the Ravenclaw house because BRAINS.

Also Kowalski and Mevin probably dress really lazily when not in their school robes, so that could be a thing.
