Gabrielle blinked at him a couple of times, waiting for him to shut his mouth, which was currently sort of ajar like he was about to speak. He didn't though, so she talked instead. "I've done magic here and I've never gotten in trouble," she said, a slight frown on her pretty face. "I mean, this is a wizarding area, isn't it? So there's magic happening around us all the time." Perhaps he just didn't know how the trace worked, she thought. Or - less likely, but still possible - maybe he was right and she'd been performing illegal magic the entire time. She didn't care too much either way, but she did make a mental note to find out what the actual rule was for later.
"No, sorry," she said, flicking her eyes down to the tattered and charred edge of his cloak before looking up at him again. Gabrielle liked clothes, but not enough to dedicate any sort of time to learning the spells one needed to be a tailor or a dressmaker. Or a cleaner, she thought, the idea tacked on at the end like an afterthought. "You could probably get a potion to get rid of the stain, but the burned bits... I don't think they can be fixed," she said, hoping she was at least a little bit helpful.
"Yeah, they were strange," Gabrielle said, glancing over her shoulder at the bookshop. There were still about ten minutes before she had to meet her friend. "Oh Jaspar... stay very still..." The blonde pointed her wand at his shoulder, where a large and dangerous-looking spider had suddenly appeared. "Stupefy," she said firmly, expecting him not to move at all.
