Sirius Orion Black, escaped convict, former Marauder, grim animagus, and godfather to Harry James Potter, was absolutely livid. After a lot of coercing from Hermione, Harry had told the animagus about how he was treated at the Dursleys. It wasn’t just their treatment of his godson that had angered Sirius so. It was the fact that Harry was placed with Lily’s sister when the Potters’ wills explicitly stated Harry was not to go to Petunia. On top of that, Dumbledore refused to let Harry go elsewhere for the summer holidays. Sirius swore he would get back at all of them somehow, though he pretended to let it go when Harry practically begged him to leave it.
