As Sherlock takes his first steps into The Great Hall a wave of warmth and the smell of melting wax washes over him. It's breathtaking, even for Sherlock, a talented young wizard who was more than enthusiastic to be starting his first year at Hogwarts. He had been waiting quite impatiently for this day ever since he received his letter a month, 2 weeks and 3 days ago. He had done extensive research into the wizarding world, with the help of his acquaintance Molly Hooper. Her mother being a witch and Molly being unable to keep secrets from Sherlock was the perfect storm for Sherlock to get his hands on all the reading material he could've hoped for. Leading up to today, Sherlock read every book Mrs. Hooper owned, as well as several others he requested. During that time he had heard from Molly that Harry Potter would be attending Hogwarts this year. The boy who lived. The stories Sherlock's heard about him, if they were true, would be simply put, brilliant.
Molly had attempted to talk Sherlocks ear off all summer about her mother's previous school years at Hogwarts, for the most part he was able to ignore her but every once and while she would catch his attention. One of the things she had mentioned that had stood out was Molly's mother's specific interest in transfiguration. Through further questioning Sherlock had discovered that his main interest and skill, what he calls Deduction, was not a class provided at Hogwarts. Shocker.
Deduction is a skill that Sherlock has possessed for as long as he can remember, he had been harnessing it through his primary school years and considered himself an expert at this point. He used it mostly to harness the skill, for example, looking at someone's nails and determining exactly what they had for breakfast and exactly which instrument they play. Sherlock in his last years of primary school had come to use deduction to determine that everyone he had met, teacher and students alike, were so blissfully unaware of the world around them it had made Sherlock jealous at times. If only he could see Harry to see what he could deduce of him.
Suddenly Sherlock is drawn out of his trance as all of the first years stopped walking. Professor Mcgonagall as she just announced herself to be, is standing beside a stool with a lumpy old hat resting atop it, Molly's books had informed him this was the Sorting Hat. Sherlock honestly can't be bothered to care which house he gets put into as long as it's not Hufflepuff. Hufflepuff's aren't inherently bad, Molly's mother had informed him in fact that they're the nicest students at the school. But that's exactly why Sherlock doesn't want to get sorted into Hufflepuff, because he considers himself the opposite of "nice" and is quite indifferent to making "friends".
Sherlock is rude, arrogant, and completely unaware of other people's feelings as Molly loves to inform him. But above all the comments she had paid him over the years, "genius" was by far the most common. And he is. Incredibly intelligent and loves to prove just how much. Sherlock knows this of course, and according to him, everyone else is stupid, just as he informed Molly she was a week ago. She hadn't spoken to him since. He often wonders how the human race has survived this long. If he was forced to pick though, Sherlock would choose to get sorted into Ravenclaw. Ravenclaw's are smart, abrasive, and exactly the kind of students he wants to associate himself with.
Although, thinking back on it, the kid he met on the train, John Watson was it? He wasn't all that bad. But John was no genius, he definitely wasn't a Ravenclaw. He seemed like a Hufflepuff, Nice, generous, and caring above all, caring. He was the only one on the train to invite Sherlock to sit with him as Molly still wasn't talking to him. They talked the whole way to Hogwarts, cracking jokes, showing off the little amount of spells they knew, and eating chocolate frogs. John was definitely a very kind person, the first Sherlock had met who didn't irritate him. But there was something else about him that adorned Sherlock to him, but he couldn't name it.
Sherlock was able to deduce however, that he wasn't an only child, most likely the youngest, due to his borrowed and ill fitting robes and battered books. The initials on his suitcase didn't match his name, they were H. W. Sherlock had deduced that the bag had initially belonged to John's older brother on account of a book of his with the same initials also, but signed "Love Clara". Sherlock shared his deduction with John who was thoroughly impressed with the rest of Sherlock's deductions but almost regretfully informed him that H. W. stood for Harriet Watson, his older sister. Sherlock was grateful John seemed impressed but Sherlock thought about his incorrect assumption the rest of the train ride to Hogwarts.
