Rainbow Dash followed Rarity into her 'inspiration room' with her gut telling her that this was a bad idea. She already knew what was coming. They most likely will end up doing each other's mane, sipping tea, and dressing up. That was if Rainbow Dash didn't have any say in what they will do.
Inside the room was a few mannequins that were lined up near the windows. There were dressers full of organized materials and clear labels. A trash bin was filled with discarded ideas that were drawn on paper. On a table was damaged clothing waiting to be stitched back up. On another table was a stylish purple hat.
"Okay. What shall we do, Rainbow Dash?" Rarity asked.
Rainbow shrugged and laid down. "I don't know. Maybe we can play a board game," she suggested.
"Darling, don't lie down on the dirty floor," Rarity told her. She used her magic to pull out two cushions from under one the tables which were meant for sitting or laying on.
"Whatever," Rainbow Dash said and relocated herself to the nearest cushion.
Rarity sat down with her. "I don't want to play a silly boring board game. It's completely pointless and certainly less entertaining than dress up," she said.
"You gotta be joking! I used to play these all the time with Fluttershy when we were fillies. Also, there's no way I'm playing dress up like a foal with you!" Rainbow Dash said, laughing hysterically.
"How dare you? Fine. How would you like your mane done?" Rarity asked.
Rainbow Dash shielded her mane with both hooves. "The way it is already! I'm not doing all this girly stuff! Why can't we just play a simple game of cards or something else?" she yelled.
"Why can't you be a real lady like Fluttershy or Twilight?" Rarity yelled back.
"'Cause I don't want to be lame. Why can't you just let me be myself and stop telling me what to do?" Rainbow Dash replied.
Rarity's horn started to glow. "That's it," she yelled. "You're going to get your mane done and you're going to like it!" she shrieked and targeted Rainbow Dash with her magic.
Quickly, Rainbow Dash barrel rolled out of the room before the unicorn could stop her with her magic. "Hah! You're going to have to try harder than that to catch this pegasus!" she teased.
The unicorn burst from the room with an agile jump. Deciding to make a rather unwise move, Rainbow Dash flapped her wings and flew up close to the ceiling. Before she knew it, there was an aura surrounding her. Trying to resist, she fought against the unstoppable force pulling her in but to little avail. Suddenly, a flash of lightning filled with windows with light and the loud sound of thunder followed.
Both ponies screamed in surprise as Rarity knocked over the lamp which kept the main room lit up. The room went dark and as they fumbled about, trying to make their way back into the other room. Rainbow Dash tried to make a safe landing down but ended up knocking over a few mannequins.
"Ow!" Rainbow Dash groaned, rubbing her injuries.
"What did you knock over?" Rarity asked as her horn started to glow again.
A glowing ball of magic appeared over Rarity's head and illuminated the entire room. Rainbow Dash covered her eyes for a second before letting them adjust to light. Her right foreleg and wing were a little bruised. Rarity sighed and used her magic to clean the mess she made from breaking the lamp.
"Way to make me hurt myself," Rainbow Dash complained as she examined her minor injuries.
Rarity turned around and snapped at her. "You know what? It wasn't even worth having you stay here in the first place! I'm sick of you, Rainbow Dash!" she screamed in anger.
Before Rainbow Dash could say anything, Rarity had promptly turned and was looking out the window. In the reflection of the window, she could see a tear falling down the unicorn's face. Rainbow Dash didn't know what to say. Suddenly, she felt guilty for all her actions. Here, the Element of Generosity had so graciously let her stay and even tried to fix her something eat but she only had been rude in return.
What's the point? I didn't mean to make her this upset. I"m better off saying a quick apology and getting out of her mane as soon as I can, Rainbow Dash thought.
"Look, Rarity..." Rainbow Dash began but the unicorn only turned her head slightly in acknowledgment. Still, she continued to talk. "I'll be honest here, I'm a terrible house quest... but I guess that you knew that already. Heck, I'm even a bad friend too." the unicorn wiped her face and turned around. "We really weren't meant to be friends anyway and um... well... I'll just... leave you alone," she finished and made her way to the door.
"Wait!" Rarity called out, rushing to stop her. "I'm sorry!" she apologized.
Rainbow Dash shook her head. "No, I'm sorry. It's all my fault anyway. I was rude and I don't deserve your hospitality," she quietly said, lowering her head down.
Rarity stopped her with a hoof on her shoulder. "It's my fault too, Rainbow Dash. I didn't mean to get upset over nothing but it happened anyway. If it weren't for me ignoring your knocking on the door, we wouldn't be having such an unpleasant day," she explained.
"No, Rare, I was the one upset 'cause it seemed like you were always trying to tell me what do with my life and such. I mean like, how I act and stuff and what I like," she said and rested her sore foreleg on her shoulder.
Taking the hint, Rarity hugged the downtrodden pegasus and was surprised to find that she was hugging back. "Sorry, you're right. I shouldn't be so critical of you for being different or having a different opinion," she apologized.
"It's okay, I'm just a terrible pony anyway," Rainbow Dash bitterly admitted.
"I think that you're a wonderful friend and that this was all just some misunderstanding perhaps. We should look past this and start over. How 'bout a compromise then?" Rarity said.
"Deal," Rainbow Dash simply said and broke away from the hug.
A/N: Depending on whether or not I see it fit, I might add a little prologue chapter if this isn't enough to end the story with.
