Timothy didn't even catch Theo catching sight of his tail in his quiet excitement. He nodded along to what Theo said, having heard that about Potions and struggling himself, very impressed that Theodore was taking it to NEWT level, that he was in that exclusive class. "You're really clever." he said honestly.
That shyness came back to him when the topic turned to him and what he liked and he ducked his head a little, fiddling with the hem of his robe. "Yeah, I like Care of Magical Creatures, but I'm doing good in Herbology and Transfiguration." Even if the latter was because he'd been doing so much independent study on the subject in an attempt to get rid of his tail. "I think Astronomy is my favourite, although I get really sleepy in class." He liked the wide open space above him, as different to a crushed Quidditch stadium as you could get. "Is Potions your favourite?" he queried, aware that you could be good at something but not like it very much.
