I have a question about the Order being reformed. I know Dumbledore told Sirius to gather up the old crowd but didn't they still believe he was the mass murderer who betrayed his best friends and the Order itself?
How would the 'old crowd' react when he told them that he didn't betray them and that Voldemort was back?
How did Sirius feel about having to face all these people again, especially since he knew what they would be thinking about him?

Any help welcome,
