"Professor Dumbledore?" Harry Potter said worriedly. "Why are you looking so upset?"
Dumbledore gazed down at the young boy wizard, his eyes twinkling in sadness behind his half-moon spectacles.
"Ah, Harry. I foresee a terrible event that is going to happen in the future."
"And what's that?"
"Professor Snape is going to-"
"AVADA KERDAVRA!"
A blast of green light suddenly shot towards Dumbledore. It struck the old wizard in the chest, then he collapsed lifelessly to the floor, stone cold dead.
Harry gasped. He looked up in horror to see where the blast had come from - and glared angrily when he saw who was responsible for Dumbledore's death.
"SNAPE!" he hollered. "WHAT'D YOU DO THAT FOR?! WHY'D YOU GO AND KILL DUMBLEDORE?!"
Snape smirked smugly.
"WELL?! WHAT HAVE YOU GOT TO SAY FOR YOURSELF?!"
"Spoiler alert."
The end.
