Their footsteps echoed on the stone walls around them as the walked up a flight of stairs that changed directions as they walked. Sherlock had lost track of the days (unusual for him) and lead John up a staircase which changes on a Tuesday. They were now late for class, and John was sweating profusely as he was determined to make a good impression on his new teacher, "A bit late now." he moaned under his breath.

They reached the fourth floor and Sherlock smiled at John nervously before pushing the door open tenderly. All of his classmates were gathered around the front table, looking obediently into the soft face of the professor. He had greying hair and what Sherlock could hear by the conversation as he entered the room, a thick London accent. "Muggle born maybe?" Sherlock thought. On the whiteboard, written in neat, swirly handwriting he had written his name. "Prof. Lestrade" it said.

(To say the least, he looked pretty cool; he seemed calm in front of his new students and he wore pretty muggle-ish clothing, except for the long robes he wore over a green jumper. Nobody turned as they entered the room quietly, the students too engaged in what Lestrade was saying to be bothered by the slight creak of a door. They sidled into the classroom slowly before joining the back of the crowd to join in on the class discussion.

The Gryffindors and Ravenclaws always took D.A.T.D.A with the Hufflepuffs which Sherlock liked. The Hufflepuffs weren't very smart but they didn't slow down the learning of others with tedious questions which had been answered a few moments prior. Sherlock despised lessons with the Slytherins. There's one brand of "full of yourself" which is perfectly acceptable,but there's another (common among Slytherins) that makes Sherlock's stomach turn. Potions with Professor Moriarty is the lesson Sherlock despises. He tries his best to enjoy and engage but Moriarty is particularly biased toward the Slytherins, awarding them with unnecessary house points, and deducting them from the Ravenclaws. To add to the misery in potions, John isn't there to share the lesson so Sherlock has to partner with Dimmock, who he doesn't get on with very well. Anderson's always on his case, spiking Sherlocks potions, stealing his ingredients, rigging his scales, scribbling in his text books, the full monty. Sherlock was just thinking of a way to turn Anderson's skin purple when he heard a faint voice in the distance.

"Excuse me? Hello?"

Sherlock snapped out of his daydream to find the whole class staring at him, Lestrade holding up a string of something and his hands covered in strange-looking goo. Sherlock blushed.
