"Well, you haven't seen her looking like this; but, this is Bellatrix Black. I took her from Azkaban; and; after taking care of her husband and Malfoy, I found her looking like this. I did a quick check of her magical aura; and; it's almost completely clean; there is no sign that she ever cast any of the Unforgivables or any other harmful spells. From what Hermione and I have been able to determine; both in talking to her and in researching different types of spells, it seems as though her husband had put her under an extreme version of the Imperius Curse. She literally has no memory of anything between arriving home after graduating in 1977 and the end of August, this year. If you'll notice, she doesn't have the Dark Mark, and it doesn't look like it was ever on her arm."
