Wonderful story! As throwaway explanations for Bob's corporeality go, "Willow" would be enough deus ex machina for me to accept it without elaboration, but the detail and complexity you put into this made it really satisfying. It was lovely seeing Bob blackmail Mai, and I like the idea that he and Harry gain friends who understand their world and don't have to be protected from the truth. All in all a lovely story. Thanks for sharing!
