"Well, what's done is done, and now I have to find a new instructor for DADA." Dumbledore muttered, but was surprised when Arthur spoke up. "Headmaster, I may have an idea about that. As I'm sure you are aware, Sirius Black was declared Innocent, and freed from Azkaban Prison recently. He has been offered his position as an Auror back, but doesn't feel his skills are up to par yet, why not bring him in as DADA Instructor? He could use something to keep him busy, and it would help him hone his skills back to the level they were before he was betrayed."
