Bryony had still never been to the markets, despite how close they were, but she had seen the things that Braith or Ophelia would bring back from their trips - part of her longed to go and see all of them for herself, but she had no muggle clothes and no idea where to get them, so she was restricted to the wizarding areas of London. She couldn't even go see the galleries she'd read so much about. None of that was Dean's fault, of course, so she smiled at him for his offer. "I'm fine, but thank you for asking."
She didn't want to seem like she was sending him away, she liked having other people to talk to who knew about art and was wary of losing the opportunity to do so in future if she seemed reticent now. "I'll probably still be here when you get back. Good luck with your idea."
