No matter what Self tried, it just couldn't get the Vibrations to reoccur. It could make its own vibrations, of course, but that wouldn't help it explain the anomalous vibrations it'd observed. It could try speeding up the Progression further and further, but then it might miss some of the finer details. It made the most sense to simply focus on studying something else until they reoccurred on their own. And so, it returned the Progression of the Superstructure to its normal pace and turned its attention to the five Interactions it'd witnessed so far. On second thought, it sped back up the Progression of the Structures that were pushing it, curious to learn what lay ahead.
        Before her brain had much time to process her situation, she suddenly found herself rapidly growing back to her normal size. Wanting to avoid any more close calls, or worse, she decided to go see Twilight while she still could. Maybe she'd have some idea about what in Equestria was going on with her, and, more importantly, how to stop it.
        As she left the kitchen and made her way towards the door, she felt lighter. At first; she thought it was just an illusion caused by her legs not having to work any more, but with each step she found herself propelled farther forwards, moving like she was on a trampoline. Pretty soon, she was moving forwards without any effort of her own, like coasting on a bicycle. Not long after that, she found her hooves unable to reach the ground, and she simply floated forwards like a puck on an air hockey table. Without any way to slow herself down or change her direction, she ended up crashing into the wall to the right of the front doors.
        She felt like throwing up, as the fluid in her ears started spinning every which way, no longer having a definitive up or down to give it a fixed direction. The fact that gravity wasn't holding her food at the bottom of her stomach anymore. She decided it was probably a bad idea to try to float herself over to the library with no way to change her direction, possibly knocking ponies over along the way. And she was quickly very glad she'd made that decision.
        It wasn't long before she noticed that her personal g wasn't stopping at zero; instead of staying put, she found herself sliding up the wall at an accelerating rate, the change in gravity's direction bringing her dangerously close emptying her stomach. Not wanting to see the previous evening's snacks a second time, she tried to slow her ascent with the wall. Unfortunately, that just caused her to tumble hooves over head, the friction against the wall being just enough to add some angular momentum to her predicament. This ended up being more than enough to tip her nausea over the edge.
        However, she didn't spew like she'd been expecting. She wretched vigorously, but achieved nothing but a dry heave. This confused Rarity, because she didn't think she'd had enough time to fully digest her food, and she definitely still *felt* bloated. And yet… her stomach was apparently empty. It was a relatively minor mystery, so she just added it to the list of things that day that didn't make sense.
        Of course, there was a perfectly reasonable explanation, namely that her stomach was no longer the organ in her abdomen that was full. She didn't know this, of course, but the question quickly fell out of her mind as she tumbled up the wall and hit the ceiling, landing on her side with a groan.
        Rarity groaned and rubbed her back as slowly stood up, or, rather, down. She looked "up" at the floor, and then "down" at the ceiling. She was certainly glad that she was inside where there was a ceiling to stop her ascent. On the downside, she was now trapped in the Boutique. She really wanted to go get Twilight's help, but she also definitely didn't want Celestia to have to scrape her shattered body off of the sky. As such, the only sensible course of action was to stay put and wait for it to pass.
        She hoped the change back wouldn't happen suddenly and drop her onto the floor, neck-first. To be on the safe side, she decided to head "down" to her bedroom and stand above her bed, so she would have something to cushion her if she fell. It was difficult for her to keep traction on the sloped ceiling over the stairs, so she ended up sitting down for a controlled slide, rather than tumbling forwards and landing on her face. It was a slow slide, because of the shallow slope of the steps, but it was also safer.
        Fortunately, she still had her magic, because she would not have been able to reach her door handle otherwise. *Un*fortunately, the height of the ceiling meant that she couldn't actually climb over the top of the doorframe and into her bedroom.
        It occurred to her, however, that the ceiling was even higher in her bedroom, and, worse still, it was *sloped*. Even if the padding of the mattress would compensate for the extra height of the fall, she'd inevitably slide towards the peak of the roof and end up falling to the floor in the middle of the room. That was certainly suboptimal, and defeated the whole purpose of…
        Her thoughts were interrupted by a knock on the door. She sighed, looking back at the slope she'd managed to slide down, one she was not keen on climbing back up. She wanted to sit down and rest for a few minutes, but she didn't want to be seen as snubbing a potential customer. Even though it was a holiday, she would prefer to greet the customer herself and clarify the matter in person. Of course, there was also the possibility of getting help herself.
        "I'm coming!" she called out, slowly making the way up the slope. It wasn't *too* difficult once she got a rhythm going, but the Boutique definitely wasn't designed to be used upside-down. Perhaps it should be, given all the strange things that had happened in Ponyville over the years. Still, she eventually made it into eyeshot of the front door and unlocked it as soon as she could reach. The knocking continued, her voice apparently not reaching and penetrating the door from the top of the stairs.
        "Come in!" she called out.
        In response, the door swung open and Sweetie Belle stepped into the Boutique. She paused for a moment and looked around. "Rarity? Where are you?"
        "Up here!" Rarity called out, waving her hooves.
