'This is just great' thought Harry. After leaving the chess room, where they had to leave Ron behind, he, Hermione, and Angelyka had to progress onward. While playing the game, Hermione had tried to get Ron to direct the chess pieces in a way that would have seriously injured Angelyka, and reflecting on that, Harry would have liked it if Ron had listened. Because the next room had contained potions and poisons, and only one of them could drink the right potion could go on.
When Angelyka created a magical force field without using her wand, Hermione snapped. She grabbed the going back potion, drank it all in one gulp, then rushed out the way they came shrieking "Oh well she's your problem now bye!"
So now Harry was faced with a choice: stay here and starve, or follow Angelyka on to the next room. It was a tough decision. Eventually he decided to drink the potion, because he was Harry Potter, and therefore had to suffer. Of course.
Harry swallowed the potion and walked through the exit. Angelyka was waiting for him. "Great! Now we can face danger together!"
Harry kept trying to move away, but she kept moving with him. And then the hall got very narrow, so they were squeezed right next to each other. Eventually, the corridor opened up to reveal a large room. And inside that room was a mirror. And standing next to that mirror was a familiar face. It wasn't Snape. It wasn't even Voldemort. Oh, and it wasn't Quirrel either.
It was Angelyka. Or, at least it looked like her. Only her eyes were red, not blue. An evil smile lit up her face, instead of the normal Angelyka's clueless one. She was wearing short, blood red robes, and her hair had red streaks in it. She was like Angelyka, but in an evil way.
"Hello Angelyka. I am you from an alternate dimension."
