He'd gotten out alive. He saved a couple of lives. His mentor had gone into retirement because of his age and the fact that he could not stand another war like that. Doyle resigned as professor, but stayed as Headmaster. He was now the only one left within the halls, the professor of Defense Against the Dark Arts. James William Wilson managed to survive the attack on Hogwarts, another one, and way now enjoying his well-deserved vacation. Just yesterday, he returned from Paris where he spend a week resting with his family and he was now rediscovering the streets of London he had not seen in ages because of his duties at school.
He strolled through Diagon Alley, observing the people and the shops that had changed since the time was here at the age of 11. It was not that long, he was not an old man, but still, things managed to change, some owners changes, some shops disappeared and some have been replaced by new ones. He wondered how interesting it would have been to observe the change in DIagon Alley, to observe how history and time take their tool on this small place accessible only to the few lucky ones that posses magical abilities. But, he comforted himself with the fact that he had witnessed another history, the history of Hogwarts, the academic institution that had made him into what he is today. Witnessing that history was something special and something he was glad to have been a part of. In some way, his name shall be remembered within the archives of the school, both as a professor and as acting Headmaster on a couple of occasions. He smiled.
As his tall persona moved through the bodies that paraded Diagon Alley, Wilson managed to his something he soon realized to be a human being. He observed everything in front of him, but was, until now, pretty successful in avoiding small obstacles, which is why he, mechanically, stopped looking down. Now, though, he hit something, or someone and he was not too happy with such a course of events. He positioned his glasses and cleaned his dark blue suit before observing the child that he had probably hit. He then directed his view upon her. He was, and that was an underestimated deduction, surprised to see that the child he had hit was actually his student, his pupil with whom he had some extra classes last term. He did not know how to react, so he just smiled stupidly and greeted her with a nod. ''It's... you'', he said, looking at her with a bewildered expression. He liked that girl, but his reaction was probably the result of his poor social skills and lack of company. He smiled at her once again.
