- In Chapter 8 of Prisoner of Azkaban, Harry is not allowed to attend Hogsmeade outings because he doesn't have a signed permission slip (presumably for his own safety), but danger finds him within the castle when Sirius Black slashes the Fat Lady's portrait which guards the entrance to Gryffindor Tower.- Today’s prompt is: Did Sirius purposely choose to attack Pettigrew on Halloween, the anniversary of Peter's betrayal, or was that a lucky coincidence?- This episode is hosted by Richa Venkatraman.- Join in the conversation on MuggleNet’s social media channels by using #PromptlyPotter
