"speak" and 'thoughts'

Chapter three: Potions

- - - - - - - -

The next morning Harry showed Severus to the Great hall. Severus ended up sitting in between Harry and Hermione. As he had promised, the headmaster announced him as a transfer student at the beginning of the meal. Half through breakfast a stern looking woman who introduced herself as Professor McGonagall (not that he didn't know that already) gave him his timetable. It seemed like Dumbledore wanted him to spend as much time with harry as possible, since his timetable was identical with Harry's. Severus wasn't exactly sure how he felt about that. Deep in thought, he swallowed his last piece of toast. He tried to block out Hermione's nagging. She was an ok witch, but far to bossing for his taste. Even as hard as it was, he had to admit that he preferred Harry.

For their first lesson they thankfully had potions, though it didn't seem like harry was so glad for it. Deciding to find out why, he asked.

"Why is it that you don't seem to like this class that much?"

"Oh, well... it isn't that i don't like potions. I actually find them quite interesting. It's just that, well you can say that the Potions Professor and I doesn't get along that well."

"Who is the Potions master?"

"Professor Snape"

Severus stopped dead in his tracks. When he realized what he was doing, he collected himself and kept on following Harry down towards the dungeons. It shouldn't really had been that much of a surprise. After all he did love potions, and Dumbledore had told him that his older self was teaching here.

He was abruptly brought out of his musings when he smacked right into something soft.

"Watch where you're going Adler"

In front of him stood an almost identical form of Lucius. It took some seconds before he remembered that he was a Gryffindor now. He was just going to answer him, but Harry beat him to it.

"Back off Malfoy"

This left him frozen in shock once again. It really wasn't like him to be left speechless, but it wasn't everyday a Potter defended him. When he regained his senses he dragged Harry with him into the classroom. He had never liked the Malfoys, and it wasn't worth it fighting with them.

They sat down in the back of the classroom, as Harry insisted upon it. His usual place at the front was now occupied by Hermione.

The classroom doors burst open and in came a person all dressed in black with an impressive swirl of robes behind. He could only stare at his older self. The similarities were unmistakable.

The whole class became quiet immediately when he arrived, and everyones attention was directed forwards.

"Ah... yes. I see we have gotten new Gryffindor in our mids. Lets hope Mr. Adler that you're not as useless as the rest of your classmates."

Severus was godsmacked. This was absolutely not what he had expected. He was just going to answer back when he got a sharp kick on his leg from Harry.

"Don't bother. It will only make it worse. He's always like that to Griffindors. The only ones he like is the Slytherins."

As the lesson carried on, Severus was getting angrier by the minute. By the time it was over, he wanted to hit the man. A look at Harry, who was having troubles restraining himself, told him that he wasn't the only one. For absolutely no reason he had been given a detention later tonight. He couldn't believe that he was to become that man. The nickname the Gryffindors had given him was extremely fitting. He was a greasy git! Severus's stomach sank by the very thought.

After potions class he and Harry got much closer. The other classes flew by, and before he knew it they were over. Soon he would have to go down for detention. The other Gryffindors sent him sympathetic looks over dinner. Detention with Snape was compared with torture.

The rest of the meal was over all to quickly. He still couldn't understand why Snape seemed to dislike him so much. After all he had to know who he was, as he had been in his situation before. Hell, he had been him before.

Soon he was on his way down to the dungeons for the second time that day. Before he had left, Harry had promised to wait up for him. That thought made him smile, although he didn't exactly know why.

Before he could blink he had arrived outside of the potions classroom. The way down was in his opinion to short. With dread in his stomach he knocked on the door softly, and the familiar silky voice spoke.

"Come in."
