Khaat found herself in the Hogwarts hospital wing. So Wilson had not killed her after all. She had vague memories of being struck with a cruciatus curse just as she fell. She was not bleeding now, and she was not wracked in torturous physical pain. She was, though, far from well. She was still dressed in the bloodsoaked clothing she had been wearing earlier. She had only been minimally tended by whoever stopped her bleeding.
Now she was confused, angry, humiliated, and above all, she could not stop the vision of her wrathfilled Uncle Remus who kept accusing her of being responsible for Shacklebolt's arrest by losing the duel. An aftereffect of the cruciatus that had not fully worn off, she knew. Knowing that, though, didn't make her beloved uncle's rage in her mind any less torturous for her. And right how, Hogwarts was the last place she wanted to be.
To her surprise, she found she still had her uncle's wand still locked tightly in her hand. A lot of good that had been to her! She conjured a piece of paper and a quill and wrote a message. She used her wand and summoned Archangel. She put the note in his talons and sent him off.
Then she got up, and made her way, one weakened step at a time, out of Hogwarts. She saw no purpose for being here right at this moment.
