Hydra took Harry to an old run-down pub and told him to ask the bartender, whose name was Tom, if he could please take him to Diagon Alley. Tom easily did this by tapping bricks on the wall and Harry was in awe of what he saw behind the wall. A huge street with people all dressed in funny clothes walking about. There were no kids who looked to be around his age, but he was okay about his he didn't really get along with kids anyways. Hydra told him to walk right down this street to the big building that had Gringotts written on it. Once he got there, he just stood there for a couple of minutes taking in the beauty of the building. Finally he had the courage to enter.
