Remus Lupin was getting bored waiting for his guard duty to get over. He had been disturbed a lot recently. Disturbed not about the problem related to him being a werewolf, and his loneliness, but about the death of his closest friend alive. But more than that he was concerned about Harry, and he knew that the child of his two best friends was not doing well at all. Harry had been close to Sirius and the loss was eating him inside out. Harry blaming it on himself was also not helping matters at all.
He was assigned the guard duty for Harry from time to time, and whenever he was there, he used to watch Harry in his room through a spell, created by none other than Lily Potter, which worked much like a remote controlled muggle video camera, albeit the remote part was taken over by wand in the spell's case.
Remus had always been intrigued with the ease with which Lily had invented that spell. A spell that had taken a month for him to master. Before he was friends with her, he knew her to be quite talented by her adeptness at spell learning. But it was only after he became friends with her that he realized that she was no less than a prodigy, a real genius. She had taken the path of a charms researcher specializing in Muggle Inventions at the ministry which he knew was well suited for her and the last project which she talked to him about, her dream project, was truly brilliant.
A sharp horn from a passing car broke him out of his reverie. This was not a time for him to dwell on past memories. Harry was grieving, much like him, and he was blaming all of it on himself. Remus knew he was far from over the loss of Sirius, but he had had people all along to help him with that, specially Tonks. He still wondered why people let him in on their lives, him being a werewolf and the danger that his presence included, though he had finally come to accept it. Harry hadn't. He still had been grieving over Sirius's loss. And it had been over a month. Harry had never been one on the healthy side but his recent condition could only be described as worse than what he looked like after a full moon. Only the questions that would be asked about how he knew it, and the reaction of Harry, kept him from telling others about his condition. Only a few days were left in Harry's birthday and he was desperately counting them so that Harry could be taken back to the people he cared about, and who cared about him. But before that he would have t o talk to Dumbledore about all the pain that he had inflicted upon the boy, even if unknowingly. He was not going to let him put Harry in such misery again if he could help it. Though he knew that Dumbledore always had the best intentions at heart, the man was human and had made mistakes in the past. The upbringing of Harry had been a direct example of his misgivings.
Sirius's upcoming funeral was another thing that kept tugging at his mind. He had asked the headmaster to wait so that Harry could also attend it and he had obliged. Looking at Harry he was glad he had made that decision, because he was now sure that Harry needed some closure to get over Sirius as did he. The funeral was going to be a small function at Godric's Hollow where Sirius was buried near the Potters, and only a few members of the order, harry and his friends and the Weasleys were going to be there. The funeral was bound to invoke some unpleasant memories and he knew it was going to be hard for him to control his emotions, but he also knew that it was going to be harder for Harry because he always had Tonks to support him and get over the loss of Sirius over the summer while Harry had no one.
Now things were going to change, he thought. He would make sure to be always there whenever Harry needed him. And he would not let Dumbledore make more mistakes as far as Harry was concerned. With these thoughts in mind, he saw his watch and realized that it had been well past his guard duty. Mundungus was late again. So he got his things together, and disappeared with a crack to inform him of his duty and get a good night's sleep.
