Luna Foretold You So
Fate looked down upon the world, and frowned. The subject of her displeasure was the older Ravenclaws of Hogwarts bullying a small Luna Lovegood. Teasing her, taking her stuff, it went on and on Then Fate had a brilliant idea! The bullies would get their just desserts at the hands of the one they bullied. It would be the ultimate prank! Yes, Luna's Seeing abilities would come in handy…
Down on Earth, Luna stiffened up straight as her eyes glowed. "One from the house of the Brave shall join the house of the supposed clever. He will show the clever the error of their ways, and in the end the house will be begging for mercy…" The Ravenclaws, being smart as they were, realized what that was and what it could mean. With a final "FREAK!" they ran off. Luna slouched to the ground and passed out.
The next day, the Ravenclaws came down for breakfast only to see two 'claws talking together. One was obviously Loony, while the other was….NEVILLE? Why was a Gryffindor at their table? But then they realized he was wearing blue robes. Luna said something to him and he started laughing. In an evil sort of way. The older Ravenclaws looked at each other and thought, OH SNAP. As they sat down, Neville turned to one of them and said in a deranged tone, "Look what my gran sent me? Isn't it COOL? MWAHAHAHA!" He whipped off his robes, and underneath he was wearing a white lab coat singed by explosions. In both hands he was holding bubbling chemicals, and his hair was sticking all over the place. The Ravenclaws screamed, and ran back to their dorms. Luna smiled dreamily, and muttered in Neville's ear. Neville got an evil grin on his face, and walked out of the Hall.
When the older 'claws reached the common room, they sighed in relief. Their respite was brief, though! With a spectacular BOOM, the front of the room exploded, and Neville barged in. "Hello, FRIENDS! I have a little SURPRISE for you! BWAHAHAHAHAHA!" On cue, a big plant-man-monster-toilet-thingy crawled out from behind Neville and started munching on a bookcase. Then, it started munching on Cho Chang. Then, it started munching on Neville. "Not me, my plant-man-monster-toilet-thingy! Them! Eat them!" Then….you get the picture. Suddenly, Neville pulled out a bottle of some weird potion. He muttered something, and drank the liquid. Everyone cringed in unison, expecting untold horror to descend upon them. Neville said, "What? It's just a muggle energy drink! Being an evil scientist can be tiring, you know!" Everyone let out their breath and sighed.
Then said untold horror came. Dumbledore walked into the room through the hole in the wall, and said, "Lemon drop?" Neville offered a bright red potion to Ol' Dumbles and the old man gulped it down. Suddenly a giant goat was standing where Dumbledore was. With a mountain-shaking BAAAAAAA Dumbledore head butted a Ravenclaw out the window and started munching on the already-munched-on Cho. Roger Davies muttered "Oh snap." All of a sudden the plant-man-monster-toilet-thingy exploded and splatted all over the wizened old goat. The giant animal went berserk and head butted itself out the window. This was the last straw for the now former bullies and they fell to Neville's feet begging for mercy. Neville smiled, slipped on his Gryffindor robes, said in a perfectly normal voice, "Okay. See you in Herbology!", and walked out the hole.
Luna, watching in the background, said, "Neville is such a good actor…I wonder if he'll go to Hogsmead with me?" Far above, Fate looked down upon her and said, "Take that you bullies! Luna foretold you so! AAAAHAHAHAHAAHA!"
