Disclaimer: If I was JK Rowling, the whole Harry Potter series would be so much more random!
Set during Prisoner of Azkaban
I spy, by my little eye, a PLOT BUNNY!
Harry, Ron, and Hermione were trying to keep awake during History of Magic. Hermione took notes to keep herself awake and so the rest of the Golden Trio wouldn't fail out of that class altogether. Ron and Harry were playing Fantasy Quiddich on a piece of parchment. Hermione scowled at them and then looked up and gasped in surprise. A white rabbit in a waistcoat holding a pocket watch and was standing behind the ghost of Professor Binns. "Professor, there's something behind you, sir." Hermione said.
"Pardon me - Miss Gibbons?"
"Er- there's a rabbit in the room -" Hermione started, but the rabbit had moved closer to the classroom door. The rest of the class didn't seem fazed, and Professor Binns droned on.
"Pst - Ron, Harry, do you see that?" Hermione asked.
"No - Krum should definitely be seeker - that would get the Irish into the playoffs!" Ron said to Harry. "What?" He looked over where Hermione was pointing. "Oh." He said. "That's weird."
"Well, looks like we're on a mission." Harry said. He pulled his Invisibility Cloak out of his pocket and threw it over the three of them. They inched to the side of the room and followed the white rabbit out the door.
