Your father is going to disown you for befriending a Mudblood," Draco warned Theo very seriously after one minor lunch-time battle in an empty classroom that had left Pansy (with the support of Tracey and Sophie) rushing off to find a prefect to reverse one of Hermione’s nastier charms that had left her with uncontrollable vomiting. Daphne had squealed unhappily at the noisome green liquid Pansy had retched up all over her shoes and robe, and had retreated with disgusted moans to the nearest bathroom to try and repair the damage as best she could. Hermione made a mental note to make that spell a standard part of her spell-casting arsenal.
