Q would have no idea someone liked him unless they beat him in the face with a shoe. He was just that kind of clueless. Savannah was nice...and pretty...and was interested in his magic. That was more than enough to get her on his good side. But like him? She was WAY out of his league in his opinion.
Still, he had no trouble agreeing to meet up with her to talk magic and show her some card tricks both mundane and augmented. He was good enough at both that it might be difficult to tell the difference.
He arrived at Off Broadway before she did and got them a table. While he waited, he shuffled his deck of cards and toyed with them.
