"I understand, Miss Granger. We still have a few days, but I would appreciate a response as soon as you've spoken with them. I've packed a few things for Miss Black; fear not, she has access to her funds separate from the Lestrange vault. Miss Black will return to Hogwarts with you for your sixth year and be placed in your house. If either of you requires any assistance with anything, Professor McGonagall or I will be happy to help. But I implore you both about the benefits of keeping Miss Black's true identity hidden."
