Isabella walked down the corridor, on her way to the dungeons. A cry made her turn her head. At the same moment that she looked to the side, Professor Trelawney almost collided into her.
"What's wrong, Professor?" she asked, hoping to comfort the sad woman.
"Oh...Sev- I mean...Professor Snape yelled at me again!" she sighed, and she thought about Professor Trelawney's interest in her head of house. She wanted to help though, so she came up with a great idea...or so she thought...
"Maybe you could help him make some potions? I bet he'd appreciate it!" she said happily.
Professor Trelawney's eyes widened and she smiled thoughtfully.
"That's it! I'll show him I can help him!" she declared with vigor as she ran down to the dungeons. Isabella shook her head slightly and smiled, changing her direction to go to the Gryffindor Common Room.
As she entered, she saw her friend Rex there. Once Isabella had happily explained what she had done to help the Professor, his eyes went wide.
"Isabel! Don't you remember? She's obsessed with Snape! He hates her!" he explained, looking scared.
Isabella's eyes grew wide with realization of what she had done. Professor Snape was going to kill her!
They noticed that it was time for dinner and left the Gryffindor Common Room. Isabella was shaking like a leaf, and even more so when she heard the last voice she wanted to hear.
"MISS DEANGELO!" Professor Snape bellowed. Rex paled and quickly said his goodbyes, running into the Great Hall. Isabella didn't blame him, Professor Snape wasn't just mad, he looked like he was about to kill someone. That someone...might be her.
"What on Earth possessed you to tell her that I may need her help!?" he shouted and Isabella shook even more, not used to seeing her head of house this angry.
"I'm sorry, P-Professor S-Snape! I r-really am!" she apologized, but it didn't work.
"Two months of detention and twenty points from Slytherin!" he bellowed.
"P-Professor! That takes us out of the lead for the house cup!" she said urgently.
Snape sneered. "Then you had better work hard to get them back, or else I will make sure every one of your classmates knows that YOU cost us the house cup! Be at my classroom at eight o' clock to serve your detention, or else!" he growled, storming away.
Suddenly, Isabella didn't feel hungry anymore...
