Wonderful-I like the way Harry sort of eases his way into town and yet at the same time takes over-stealing Hermione, customers, then the parallel research. Very realistic that Severus would be somewhat jealous that Harry figured it out, even though really it was both of them, and then he would leave, only to be angered by Harry's generosity with crediting him. Wonderful way to bring them together again at the end. Very nice work.
