Twilight was taken aback by this statement. "What...what do you mean?" she stammered. "I mean, why can't you be a true friend and help me out instead of taking advantage of me? What happened to Rainbow Dash? Where has she gone?" Rainbow was on the verge of crying at this point. Twilight bit her bottom lip and reared slightly.
"Rainbow Dash, you don't understand what this means to me, I've always wanted a daughter, and I'm so close now, I just can't leave!" she explained. Rainbow Dash huffed and flapped her wings with immense power, but all she did was fly up about half a metre. Twilight rolled her eyes and grabbed Rainbow Dash from the air and walked her down the stairs. "You seriously need a bath, Sunny. A bath is nice in the early morning, anyway." she grinned.
"Twilight, don't just ignore what I said! Fix things! Please, Twilight!" Rainbow Dash sobbed. Twilight's smile dropped as she shook her head tiredly. "Rainbow, stop trying, You know it won't get you anywhere." she rolled her eyes, starting up a warm bath. Rainbow Dash sighed and struggled with her diaper. There was a toilet right there, she could use it! She yanked at the straps to no avail. After half an hour of prep, she was in the bath. She was happy at the warmth that overcame her body, making her feel new and fresh. She relaxed her muscles and let herself float in the water, sighing with content.
Twilight washed Rainbow Dash softly, shampooing her whole body without a single complaint from Rainbow Dash. "Ok Sunny, It's time to get out." Twilight said softly. "Aww, c'mon Twilight, just a little longer!" Rainbow whined. Twilight gave her a stern glare. "I'm sorry, what did you call me?" she huffed. "Um..Mom." Rainbow corrected, closing her eyes. She wished the tub would grow bigger, and warmer, carrying her away down a long stream, far away from Ponyville. Her little body would painlessly change back to normal, the effects of poison joke would wear away, and she would be lifted back home by her wings.
Rainbow Dash's coat and mane were both soaked as Twilight scrubbed her with a towel. The towel was straight from the dryer, still hot. Rainbow Dash smiled in it's warm embrace, wrapping it tightly around her. She had been in the bath for an hour, and finally it had grown too cold. Orange dye dripped from her hair. Twilight noticed this, and gave it a good scrub with the towel. Rainbow Dash giggled, the towel was sure ticklish. She never knew she was so ticklish! "Ooh, somebody has a little tickle spot!" Twilight laughed, tickling Rainbow Dash's head. Rainbow Dash fell back and laughed loudly, trying to push Twilight away.
She kicked her feet and rolled her head until finally Twilight stopped. "Well aren't you giddy!" she chuckled. Rainbow dash giggled, nodding. Then, stopped abruptly. What on earth was she doing, treating Twilight like her own mother! She didn't know, but she was sort of...enjoying it? She didn't understand it, but Twilight was actually quite a nice mother. "
"Now, I have some news..." Twilight smiled weakly. "I'm time for you to be potty trained. If you have to go, tell me, and I'll get you to a toilet. Ok? Let's see how well you can do with this, and maybe you won't have to wear diapers anymore!" Twilight cheered. Rainbow smiled wide, and her eyes opened brightly. "No way! Awesome!" she giggled. Then, a thought struck her. "Mom, I have to go, now." she said more seriously. Twilight took the hint, and lifted Rainbow up into the air, sitting her down on a little plastic potty that had been safely tucked in the corner. Rainbow Dash sighed, and released her bladder into the bowl.
It felt good to have an empty bladder, such a weight off your shoulders. Twilight gave Rainbow Dash a wipe and lifted her off the potty. "You must be starving, let's go have breakfast." Twilight chimed, strapping a diaper on Rainbow Dash. They walked down the stairs together to the kitchen, where Twilight proceeded to place her daughter in a high chair. Rainbow Dash gagged when the vile baby food touched her pallets, nearly spitting it out as a reflex, but she knew that if she didn't swallow it, she would just get more.
Rainbow Dash stepped off the potty proudly, letting Twilight wipe her. "Mom, I want to fly! I'll fly higher, faster, and better than ever before! I wanna go to flight school! I'll be fastest, I swear! Please!" she begged. "You're still much too young! You can still barely fly, Sunny Dreams! You need to grow up first!" Twilight assured. Rainbow sulked, trotting past Twilight and storming out of the room. Twilight smiled and shook her head. Rainbow dash huffed as she plopped into her crib.
Why didn't Twilight understand? She wanted to fly, and she could! She just needed practice. Twilight walked in and smiled at the new patch of yellow dye on the newly cleaned bedsheet. "Time for bed, kiddo." she cooed, pulling the covers up to Rainbow Dash's chin. "Have sweet dreams, Sunny.".
Suddenly, there was a knock at the door. Twilight kissed Rainbow Dash on the head, and trotted down the stairs.
"Oh, hey Flu-"
"OH TWILIGHT, WHERE ON EARTH IS RAINBOW DASH?! NOBODY HAS SEEN HER SINCE SHE WENT FLYING TWO DAYS THREE DAYS AGO! TWILIGHT, I MISS HER! EVERYPONY IS LOOKING FOR HER! DO YOU HAVE ANY IDEA WHERE SHE IS?!" Fluttershy sobbed, tears pouring from her eyes.
"Fluttershy, I have no idea! Calm down, stop crying, she'll turn up eventually, It's gonna be ok." Twilight coaxed. Rainbow Dash listened from the crib, she felt sick. She felt like she was betraying her very best friend. It just wasn't right. But what could she do? Nothing, nothing at all.
