++++++++++++++++++ Hello Potions my old foe. ++++++++++++++++++

Harry stood outside potions class. It was the first day of the new year, bright and fresh and exciting. It was going to be a great, great year. His summer vacation hadn't been any worse than any others, and he'd even had a decent birthday with a cake from his friends and everything. Then the trip to Hogwarts had gone smoothly, despite the strange creatures pulling their coaches. Nothing horrid or unusual had happened. Even Malfoy had been his usual nasty, jealous self, even if he was rather sullen and bitter about it. It wasn't good that Malfoy was picking on him, but at least it meant things were as normal. Harry couldn't even begin to imagine Malfoy being nice. A Malfoy being nice was either a symptom of mental illness, or a sign to run before the other shoe dropped.

His two best friends Hermione and Ron were acting the same as always: Hermione trying to the two boys to study better, and Ron too busy being mad keen on Quiddich to take her advice. Yup, it was a great start to the year. Even though the threat of Voldemort hung over everything, from the way people spoke, to their fervent wish to learn defense spells. Even though there was an unspoken tension in everything, this year was starting out just great.

Except for potions. Potions was never great. And it never started out well either. Harry just knew that Snape would have something extra nasty in store for him on the first day back. He just knew it. Things were going too well. Things were just a little too normal. Professor Snape would cook up something evilly difficult just to disrupt the peace, if nothing else. Harry took a deep breath, let out a sigh and opened the door. Hermione was already sitting inside, and he gratefully took a seat beside her. Just in time too. Snape whirled into the class like a thunderstorm soon after Harry was settled.

"Welcome back.." Snape paused and gave Harry a look which conveyed that Harry wasn't included in that sentiment. ".. This year is going to be the toughest you've ever been through, and Potions class will be no exception. I will expect nothing but excellence from you each and every day you are in my classroom. If you feel that you are somehow lacking in any way.. "He paused again to look at Harry. ".. I suggest you leave now."

Harry just looked determined. He didn't care about Snape's threats. Potions was a required class if he wanted to be an Auror, and he wasn't going to let anything get in the way of that, not even a bitter old Potions master.

Snape surveyed the class carefully, looking over who had dared return to brave Advanced Potions. He apparently didn't like what he saw. He turned his back and started making notes on the board for the class to copy down. Harry breathed a sigh of relief, and started writing about the uses of feathers in sun-shield potions.

The notes were surprisingly short. The whole class put down their quills in relief. Then Snape favored the class with a peculiar smile, sending a shiver down everyone's back.

"Get out your cauldrons, you will be making this potion alone."

"And make it good, or else points WILL be deducted."

Harry and Hermione looked at each other in disbelief.
