First of all, the giant. Or, the half-giant to be precise. Sherlock had thought he was part giant, since the moment he saw him. He had said that his name was Hagrid. Not a typical giant name. While the party walked to the boats, Sherlock had caught up with the half-giant and he'd asked him: "Which one of your parents is a giant?". The man looked down on him and had patted Sherlock on the head. "Ye ar' a clever boy, ye ar'" He had said. Sherlock had tried to shook the other man's hand off, but his hand was so heavy, he had not succeeded. Hagrid had leaned down to face Sherlock. "But don't ye trouble tellin' anyone, d'ya?" Hagrid had spoken in a low voice. Sherlock had nodded unsure. His question was still unanswered, but he'd trouble to know later. Somehow, he began to trust the half-giant. Something in is voice was purely friendly and helpful.
On their way to the castle, Sherlock got in a boat with a blond, small boy with a dinky face, a boy who was talking very loud with the boy next to him and a quieter boy with black, short hair, who was eyeing him all the time, while talking to the boy with the brown hair. Sherlock did not like this boy. Something in his air made him shiver. But he was not sure what it was. He thought it was quite interesting though. Not many boys of his age were interesting to him. Most of them only were interested in quidditch and spells that make your bogies run dry. Regardless of the origin of the uncomfortable feeling, he would find out.
A tall, rather severe-looking woman had welcomed them to the castle. She was wearing a green wizard-hat, which covered most of her black hair, tied into a tight bun. She had greeted them with great formality and had accompanied them to the stairs where they were standing right now. Sherlock thought she was a tough woman, which showed though the amount of smiles she gave. She was a powerful witch too. She did not blink very often. She was alert, but not evil-hearted. She did look confident.
The blond boy and Sherlock still stood next to each other. The boy was small, but not fat or chubby in any way. It was difficult to tell how his muscles were developed through the thick robes he wore. The boy did not look like someone to challenge him. His face was dinky and without any ill-intentions. His blonde hair was cropped short. The blonde noticed Sherlock watching him and looked back. Sherlock briefly made eye-contact, before turning his eyes away. Unfortunately, he looked in the way of the quieter boy with black hair. Sherlock could observe him better in the candle light, but his vision was still not optimal. The boy was small of stature, like the blonde on the right of Sherlock. The boy had messy black hair and a vulgar grin on his face. The boy was still eyeing him. Sherlock did not want to show any emotion. Sherlock eyed to the right of him, where the blonde boy was still looking at him.
'Ermm... hi' the other boy said, showing his open hand for Sherlock to shake. The boy's eyes were blue and looked him right into his eyes. Sherlock got an honest impression of him, so he grabbed the other's hand and swallowed.
"Hi. My name is Sherlock Holmes."
