Astoria raised a brow at his position. It seemed a bit uncomfortable, but to each the own, she figured. He was acting a bit strange and she wasn't sure how to point that out without sounding rude. He had come to visit her after all, the least she could do was be polite and courteous. Telling him was being a bit suspicious would do no good.
His shifting away did not go unnoticed either. Julian probably shouldn't have been there in the first place. Keeping that in mind, Astoria move away even further from him, making sure there was plenty of room between them. There was no point in being subtle. They both knew he didn't want to get sick. And she didn't blame him. "Are you sure you are?" Asking a second time was worth a shot, wasn't it?
How was she? "I'm...a bloody muggle." Or she almost was. She would lose her magic completely soon enough. She would rather jump off the Astronomy Tower, though that probably wouldn't go over very well with certain people. "I'm not quite sure how to deal with the situation," she said, her voice tinged with anger. Sometimes she couldn't keep it in check. It did distract her from him, however, and that was certainly something in his favor.
