Theo sent a few letters with his owl, which hung around to await her replies after she asked it nicely to do so with a series of hoots. Their correspondence was rather infrequent, but often enough that Hermione was glad to reassure her parents that she had a penfriend. They didn’t discuss anything especially deep, being careful on both sides not to put anything in writing about Dark magic. So their letters were filled mostly with chatter about wizarding subjects they’d been reading about, and snippets of personal information like their favourite colours, what religion she believed in, and what their wands were made of – Theo’s new wand was aspen with a dragon heartstring core, and she told him about both of hers, though she described the core of her homemade one simply as a "magical feather". It was definitely for the best that content stayed light, for her father – much to her embarrassment – read over a couple of Theo’s letters, checking to see that there was nothing bigoted or rude in them, and thankfully they passed his scrutiny.
