Chas didn't really react to Theodore coming in, neither smiling nor frowning, which really was a summary about how she felt about the man. Truthfully, she didn't have much of an opinion. He wasn't a Death Eater, though his father had been, but he also wasn't part of the rebellion, either. Not to mention, Patience seemed to like him... which sometimes actually did weigh to an extent on Chas' opinion.

She looked down and made a face. "I never get sick."
