Rainbow Dash was flying along, as usual, sightseeing and testing her wing’s limits. There was nothing Rainbow Dash enjoyed more, besides perhaps meeting with pinkie pie to mess with other ponies all day. She was approaching the Everfree forest, when she noticed a mysterious hole in the ground. She was instantly filled with curiosity, as she had never seen it before. As her curiosity got better of her, she slowly descended towards it and peered inside. It was pitch black, and obviously extended a considerable distance. Rainbow Dash knew this was new; as a filly, before she was even eligible to pass flight school, she was forced to memorize all of Equestria in order that she make it as fast as she can to wherever disaster may arise. Not once did she ever see this. Rainbow Dash’s bravery told her to jump in, while her logic nagged at her and told her to stay put. Of course, as always, bravery beat logic. She jumped and descended for about 5 seconds before spotting a surface. Rainbow Dash opened her wings at the perfect moment and slowed to a landing speed. Once she was grounded, she looked around a bit. Rainbow Dash could see nothing but what was above her and that was a bit of light from the entrance of the tunnel. She was about to leave and just ignore the tunnel forever, when she felt the ground shaking. For a brief second, it stopped, and she sighed in relief. A few seconds later, the ground opened up, and she fell into a large, dim, white room. Rainbow Dash landed uncomfortably inside, as she wasn’t really expecting the sudden fall. The ceiling closed behind her, but Dash wasn’t worried about that. She was more concentrated on the center of the room. There appeared to be a silhouette of a pony. Rainbow Dash could tell it was one of her friends. The mane of her was quite easy to recognize. It had to be twilight. Rainbow Dash walked closer to the silhouette. “Hey Twi, what are you doing here?” Rainbow Dash asked her. There was no response from her unicorn friend. “Twilight, are you okay?” Rainbow Dash tapped her on the neck. To Rainbow Dashes extreme surprise, Twilight fell into the floor and the room was instantly illuminated, easily revealing the size of the massive space. There was a static noise, then some maniacal laughter audible from a large speaker hanging from the ceiling. “Wha- what the? Who’s there?!” She asked in a terrified tone of voice. A few seconds later she heard it. “Why hello, Rainbow Crash! Nice of you to drop by!” Rainbow Dash was shocked. “F-Fluttershy?!” “yes. It is me. You know Rainbow Dash, I’m moderately sad to do this to you! But you had it coming…” Rainbow Dash was confused and scared at the same time. “Wh-what are you talking about?!” “You know DAMN WELL what I’m talking about Rainbow Dash! Don’t play jackass with me!” Rainbow Gasped. “You couldn’t possibly mean… You don’t truly forgive me do you?! I thought we said we would let this go!!!” “What’s with all this ‘we’ stuff? You should replace all those ‘We’s with ‘me’s. Oh Rainbow Dash, you don’t know how much your ‘surprise’ affected me. To put it simply, I’ve been spent months working on what the appropriate technique would be to torture you. There are 4 stages. They get progressively worse. Ready? Let’s begin.” The speaker was pulled by motor out of the chamber. Rainbow Dash was upset that Fluttershy hadn’t forgiven her, but Rainbow Dash was also un-intimidated by her setup. Stage one began with the walls groaning and moving inwards on Rainbow Dash. They stopped after moving a few feet. The buildup of pressure was obvious, but all Rainbow experienced was her ear popping. “PFFFFTTT! Are you serious Fluttershy? You think a little ear pop is gonna hurt me? I always knew you were too gentle to cause any harm!” Fluttershy only replied with a maniacal laughter. “That was only phase one, peabrain! Phase 2 is where it gets serious.” With that, the walls started moving in further, this time a few meters instead of a few feet. The pressure inside was much greater now, and it was making breathing harder for Rainbow Dash. She knew, based on the amount of increase in movement in just one phase that she wouldn’t be able to survive much more. “Ready for phase 3 Rainbow Crash?” Fluttershy asked rhetorically. “W-wait! How much farther will they move?!” Rainbow asked in desperation. “I don’t know, maybe around 10 meters. You can’t prevent your punishment, so face the music and SHUT UP.” She replied. With that, the walls began moving again. Rainbow Dash was facing an extreme amount of pressure, and her head felt like it would quite literally pop. “Having fun, Dash? I know I am. Phase four is next. It’s a bit different than all the other phases.” A few seconds after she stopped talking, a small hatch opened and allowed a large amount of air to leave the room. Rainbow Dash breathed a sigh of relief. Fluttershy only replied in a psychotic giggling. “Oh Rainbow Crash, things are going to get WORSE, not better! I don’t want you to die in this last phase, so I’ll give you some advice; Hold your breath and don’t let it out.” Rainbow Dash was confused, but she felt like Fluttershy was being serious about holding her breath, so she went ahead and gulped down all the oxygen she could fit into her lungs and waited. The walls began moving outward as soon as the hatch had closed. “A vacuum…” Rainbow Dash thought to herself. “No wonder I need to hold my breath.” Her ears popped again, but the walls kept moving. Eventually, her eardrums burst and a steady flow of blood came from both sides of her head. Rainbow Dash wanted to scream, to holler, to beg for mercy, but the force of the vacuum attempting to take her sweet breath from her kept her mouth shut. Rainbow’s body began to implode on itself, and eventually one of her ribs snapped. Fluttershy grinned at the sight, and shut the chamber down. The hatch opened and Rainbow took a deep breath of fresh air…before collapsing to the floor with a loud thud. Fluttershy took Rainbow Dash to the hospital with the story she had been preparing for days; “She was hit by a dragon, and it screeched into her ears and broke her eardrums. She fell to the ground, I tried to catch her but I couldn’t make it in time. She broke her rib on impact.”
Rainbow Dash woke up in a hospital bed. She had tubes from her hooves and 2 devices to aid in her hearing temporarily stuck into her ears. She groaned in agony when she saw she was wearing a lower body cast, and wouldn’t be able to leave for several weeks. She quickly looked to the door to find it opening. She shook with terror. It was Fluttershy. Rainbow Dash just waited, watching Fluttershy’s every move. They exchanged several glances. After a few seconds of staring into each other’s eyes, Fluttershy ginned evilly. “I guess then… we’re even…” She said. She turned to leave, and her mane lifted, revealing a long scar for about half a second…before she disappeared from view behind the door.
