Translation: The Irish kid’s been blowing shit up since the day he got here, ask him
I always wondered with Seamus… He can’t be that terrible at magic, I mean he can conjure a fox patronus and was in most of Harry and Ron’s classes and we know they’re not terrible at magic. He probably follows the steps like it says in the books and studies but he still manages to set things on fire or blow them up. So what if that’s just a part of his magic? Like if different people were specially skilled in certain areas.
What if someone was especially talented in levitation that they levitated in their sleep or never really touched the ground when they walked.
Imagine a muggleborn growing up pretending to be a mermaid and can hold her breath for longer than normal and it turns out she has a special talent for water charms.
That wizard using wandless magic in the Leaky Couldron making his toy cars move as a boy, sending books flying across the room when he’s upset, now being able to move everyday things with a wandless gesture.
And Seamus’ accidental explosions one day leading to wandless, wordless fire conjuring?
