Aleski had always enjoyed potions. He saw it as not a branch of magic, but an art. You must be extremely specific to get exactly what you want, or course, but if you changed the process even slightly, the effects could be... interesting. He often enjoyed experimenting with potions in his free time but was never able to take it to far, as if something went totally wrong he would end up with rather a lot of explaining to do.
He never understood why the subject had to be held down in the dungeon although he suspected it may have something to do with space. It had always added a bit of a gloomy atmosphere to the subject, even the new improved dungeon he saw when he came down the stone steps and entered the classroom, and it was always colder than upstairs. He had taken to wearing a hoodie under his robes as sometimes the school jumper wasn't quite enough and his old professor had never gotten him into trouble for it although he suspected this new teacher may have something to say about it. He knew nothing about her except that she was head of Gryffindor, so she probably stood for bravery and all that, which could occasional effect work and grades. He saw a confused looking Gryffindor and muttered sixth year and above, look at your time table genius as he walked past.
He found an empty table and sat down before setting up his cauldron and waiting.
