Walking through the [Ministry of Magic] for the first time, Harry is amazed by the entrance hall and the [Fountain of Magical Brethren]. He and Mr. Weasley then check in at the desk and take the elevator to level two and the [Auror Headquarters].
In [Auror Headquarters], Harry and Mr. Weasley chat with [Kingsley Shacklebolt], pretending not to know him more personally, and with Harry all the while staring in awe at the evidence of Kingsley's search for Sirius Black.
Mr. Weasley leads Harry into his office, where they chat for a bit about Mr. Weasley's job, until [Perkins] rushes in to tell them that the time of Harry's hearing has been moved, and he's already five minutes late, prompting Harry and Mr. Weasley to take off for [Courtroom Ten].
