Chapter 1 – Volatile Potions

"Potter, my office NOW!" Professor Snape snarled at Harry, his piercing black eyes flashing dangerously.

Harry stared back at Snape. "No." he replied defiantly. At this, Harry's classmates gasped in horror. First lesson of the new school year, and it looked like Harry was about to lose them a lot of house points. If Snape didn't kill him, the other Gryffindors would.

Neville paled and looked as though he might faint. Even one or two of the Slytherins looked scared as they waited for their Head of House to respond.

After a few moments of stunned silence, Snape grabbed Harry's arm, and dragged him into his office – slamming the door behind them so hard that several bottles fell off the shelves onto the classroom floor.

Ron and Hermione gave each other horrified looks. Shouting and crashing could be heard from Snape's office, although the students outside couldn't make out what was being said. After a few minutes, everything went quiet – but Harry and Snape didn't reappear.

Ten minutes passed in an uncomfortable silence, then Hermione went over to the door, knocked, and tried to open it – with no success. "Ron, I'm worried about Harry, I think we should fetch the Headmaster. I've never seen Professor Snape look that angry before"

Ron looked a bit green, "I don't know Hermione; I think Snape would go ballistic if we called Dumbledore, it might make things worse."

"And where is Professor Snape?" a familiar voice asked quietly from behind.

Hermione looked relieved, "Oh, Professor Dumbledore, it's Harry, he and Professor Snape had an argument, oh it was awful, you see ...", she started, talking far too quickly, as she tried to explain what had happened earlier. The Headmaster raised a hand to stop the girl's rush of words, "All in good time, my dear. Where are they now?"

The Headmaster instructed the class to remain seated, and opened the door with a flick of his wand. He entered the office, closing the door quietly behind him. A few minutes later, he emerged alone, with a serious look upon his face. "Ms Granger, Mr Malfoy please inform the other Professors that I wish all staff and students to make their way to the Great Hall immediately. The rest of you will make your way there now, and wait quietly until I arrive".

"Is Harry okay? He …" Ron started to ask, the Headmaster looked at him and repeated kindly but firmly, "Please go to the Great Hall now", before returning to Snape's office.

Fifteen minutes later, Dumbledore entered the Great Hall. Professors and students alike stared at him, wondering why they were there. The seventh year Gryffindors looked past the Headmaster, hoping to see Harry, but he wasn't there.

After making his way to the head table, Dumbledore stood up, surveyed the room carefully and declared, "I have a grave announcement to make".
