Muggleborn kid with a talent for magic. Not real magic. Like, sleight of hand magic. And then a prefect catches them doing something like making a ball appear to vanish or whatever, and just loses their shit because this 11 year old kid has utterly mastered Vanishing Spells and what the hell how is that even possible.
