Outside Sugarcube Corner
Pinkie had just had a day at the spa to forget what happened on the previous day. But even this could not hold her evil side back.
Before she knew it, she was standing before a yellow unicorn, pleading for her life. "Please, let me go! I won't tell anypony! I promise!", pleaded the pony. Pinkamena took over, and grinned widely. The unicorn's expression was that of shock. Then, it happened again. Blood once more splattered on the floor. "A few cuts on my flank won't stop me, you sicko." Sicko??, thought Pinkie. Just as she was going to stab the unicorn in the shoulder, it got out. She tried to run away, but her forelegs were so badly sliced, that they looked like gory stumps.
Something snapped inside of Pinkie. She was tired of having this second side bossing her around. The unicorn fell to the floor, and almost immediately, a pool of crimson blood seeped out from her. Pinkie ignored her, focusing her eyes on herself. "You said that I was supposed to be happy from this! But it isn't that way!", Pinkie Pie yelled at herself, her temper growing as fast as a wildfire. "You never helped! You never helped! You never-" Pinkie was silenced as a wave of insanity washed over, all her angers disappearing.
"NO!" ,yelled Pinkie. She began hitting herself. It was a long struggle. It brought her up to the 1st floor.
She was weak. She staggered to the wall. "I-I did it. I got rid of her." Said Pinkie. Everything became blurry. Then, everything faded away.
Inside Sugarcube Corner, the Following Morning
"Pinkie?", asked the curious purple pony. "Are you there?" Twilight Sparkle, and her friends, hadn't seen Pinkie ever since yesterday evening. Twilight Sparkle saw a figure, it was terrible. She screamed, and her friends came bolting to her side, asking her what happened.
She pointed downward. Slumped against the wall was a terrible sight. Pinkie Pie was slouched against the wall, bloodied up.
Her flank was bruised, and looked like it was broken. Her mane and coat had red blots and brown stains on them. She had a gash in her chest. All in all, she was a mangled, bloody mess. As the paramedics arrived and carried Pinkie out. She noticed, out of the corner of her eye, Pinkie had something in her hoof. Something like a doll. It was bloody, too. Twilight looked down in sadness. Then she realized it.
Pinkie was holding a homemade Rainbow Dash doll.
