In the Ministry Atrium, the supposed Boy Who Lived, Barry Potter, spit on Fudge’s photo. When the Aurors gave chase, Barry escaped through the Floo. The Aurors went to Potter Manor and arrested Barry’s twin brother Harry (the true Toddler Defeater of Voldemort), despite Harry’s protestations of innocence.
At Harry’s trial, not only did Ron Weasley and a strangely-monotone-speaking Hermione Granger testify against Harry, but Dumbledore talked for five minutes about all the ways that “Harry is going Dark.”
Three years later, Dumbledore showed up at Harry’s cell in the maximum-security wing of Azkaban. Dumbledore tried to hand Harry a written pardon. Instead of taking the pardon, suspicious Harry demanded to know, “What’s the catch?”
It turned out that if Harry accepted the pardon and left Azkaban, he then had to do one of two things immediately: marry Pansy Parkinson (because of a new marriage law that had been passed a year ago), or else track down “the eighth horcrux,” which was somewhere within an active volcano in Hawaii.
Harry’s reply to Dumbledore was to reach through the bars and to grab the robes of the nearest Auror, to pull him close, and to punch the Auror in the face. This new crime of “Assaulting an Auror” was not covered by the pardon.
The End
