Harry was staring at the ceiling of Number 4 Privet Drive. He was extremely hungry, as his uncle was starving him, but he knew that his body would not respond to his bidding while he reminisced about Sirius's death over and over again. Sirius Black, he thought, was an ex-auror, ex-convict, false Azkaban prisoner, illegal Animagus, Harry's godfather, Harry's only father figure and relative. Sure, he had Remus, but the man was not as close to him as Sirius.
After Sirius's death, Harry had to rethink a lot. He had decided to work on his Newts harder, also to defeat Lord Baldemort once and for all, to avenge Sirius. He made a mental checklist of what he should do.
1- learn about wizarding culture
2- Learn Occlumency
3- learn if he had any magical talent.
4- learn if he had any ancient houses.
Harry started to think how to do any of this. He had wanted to learn Occlumency, but he knew that Snape's teaching method was obviously because Voldemort would never let anyone into his mind, let alone read his memories to learn Occlumency, not even Bellatrix. Eventually, he made a plan. he knew that leaving Privet Drive would alert Dumbledore of his whereabouts. So, he decided to call the only person who would help him without questioning or annoying him.
"DOBBY!"
