Harry Potter's sister ~~~ Fanfiction

Why??? part 90

Word that an unknown man could be sneaking around the school caused a great deal of panic amongst students. Girls in particular began trading jinxes and hexes, as well as physical methods to counterattack against any man seeking to overpower them.

Malfoy began joking about a scary man going after Gryffindor Children and ended up scaring some First Year boys into tears. He found this funny, but when no one was looking later Harry fired a Stinging Hex at his backside. He was of course questioned by Professors McGonagall and Snape but there was no proof he'd done it and, as McGonagall pointed out, the Stinging Hex was a well-known spell and everyone Second Year or Higher would know how to cast it.

Meanwhile, Harry retrieved the Marauders Map from his trunk and used it to search the school for any unknown or uninvited people. Unfortunately this proved difficult, there was no one inside Gryffindor Tower that he didn't recognise, but there were dozens of names all over the castle that he didn't, Hogwarts after all had a population of several hundred students.

Stumbled by this mystery he turned back to the other. Sirius Black. The search of the Castle was called off at around dinner time. Harry retired to the Room of Requirement. This was normally time he spent analysing Lawrence's paper, but the look on Black's face just didn't go away. Harry was again reminded of a conversation he'd recently had with his friends regarding Black's lack of trial. Suddenly the question of his guilt was beginning to register. Hermione had done a fair bit of research on Black before Christmas, after a bit of persuasion he got her to point out the sources she had researched.

Because it wasn't homework or anything, Hermione had not written anything down so Harry had to review the books and old Prophet articles himself. On the plus side it allowed him a fresh perspective.

Sirius Black was the eldest of two sons in the House of Black, which was something Hermione forgot to mention, that he had a younger brother. He was cast out at the age of sixteen, Harry couldn't find out why but it was likely he fell afoul of the family's values. This alone was probably a big red flag in Black's guilt. If he was such a big supporter of Voldemort, why was he cast out a family known to sympathize with him?

Harry looked over the case against Black, he was seen killing Peter Pettigrew and twelve Muggles. There were actual witnesses who saw Pettigrew name Black as the one who betrayed Harry and Emma's parents. But if Black so callously murdered Pettigrew and betrayed the Potter family, why that look? Black looked like Harry had very personally hurt him, but it was the other way round, Black had betrayed Harry.

But then why did he look so betrayed, and if Black was such a Dark Wizard, how could he cast a Patronus Charm?

"What the heck is going on?" Grumbled Harry.

He needed another perspective. One that was logical, unbiased, intelligent and very good at spotting inconsistencies. Thankfully for Harry, there was one person he knew held all those attributes.

"I'm worried about Harry." Said Emma. "He's closed himself off ever since he went after Black."

It was after classes on Monday, there was supposed to be a duelling session amongst the group in the Practice Room but Harry had yet to show up.

"I think he might have started obsessing about Black." Said Hermione. "He asked me for all the research I did on him a few months ago."

"You don't think Harry is going to…" Colin began to ask.

But then Harry entered the room, he could immediately tell by the sudden silence and the way everyone was looking at him that he had up until a moment ago been the subject of discussion. But that wasn't important right now.
