"Mr. Malfoy, I’m sure you’re aware of how important Miss Granger is to those boys. She’s important to more than just them in our world. I’ve made arrangements for new head quarters, you’ll both have individual passwords through two separate portraits. You’ll share a bathroom and a common room. You will make sure Miss Granger eats, you will make sure she turns in her assignments, you will be responsible for her. Think of it as penance. Reparations for what was done to her at the hands of your blood. Tomorrow, we will travel to Hogwarts via side-along. Your things have been moved there already. I hope for your sake you’re successful in eliciting some sort of reaction out of her"
