"I simply can't believe you Rainbow Dash!" Rarity exclaimed as she circled the Pegasus currently serving as a clothing dummy. "Honestly, we all knew that Twilight was going to find out about this town's secret."
Dash didn't reply as Rarity ranted at her, still making a new dress. "But there's a proper way to do it Rainbow Dash, and you know full well that we all drew straws to see which of us would tell her! You couldn't just wait until Fluttershy told her the truth, did you? You just had to rush in when you knew she was a flight risk. Didn't you remember the whole ticket incident?"
Once again Dash didn't reply, so Rarity moved to her other side and began sticking needles into the hem there, trying to get it to line up perfectly. "To make matters worse, you tried to use it to your advantage! How could you! Yes, yes, I'm aware you feel a deep, mystical connection with Twilight, but darling we all do. It's a part of the Elements of Harmony and that's why the mayor entrusted us to tell Twilight when she was ready."
A little magic to grab a needle and thread later, she began sewing up the hem while continuing to scold the strangely silent Rainbow Dash. "But you couldn't just be a good little filly and wait your turn, no you had to bolt in and tell her. And now nopony's seen Twilight for over a week. Just look at poor Spike! He's been moping all week, and not even a full cart of gemstones could get so much as a reaction out of him."
A little too much power in one of the insertions accidentally poked Rainbow's fetlock, causing the pony to let out a muffled yelp of pain. The white unicorn looked up with an imperious frown at the gagged Pegasus. "Sorry Dash, I didn't mean to poke you like that. Now keep holding still and we can finish this up. Then you'll be going over to Sweet Apple Acres for bucking practice, and then Fluttershy wishes to talk with you... You remember Fluttershy's dark side right?"
The whimper of terror from the vibrant flier alerted Rarity to the fact that she remembered just why no one did anything to upset the usually timid and meek Fluttershy. The Stare was just the tip of what dark Fluttershy could unleash. "I know darling, but honestly, what can you expect? Twilight was to be brought in the circle by her, and you know how she's looked forward to it. She hadn't had one since... since... why I dare say she hasn't had one to break in yet. Oh my, you are in for a bit of trouble, aren't you?"
The soft creak of leather alerted the seamstress to the fact that Rainbow Dash was once again attempting to break free and run for it. However, this was one of Fluttershy's best designs and didn't even budge a fraction of a centimeter. "Now Dash, darling, this could have all been avoided if you simply followed the rules of the game. Fluttershy was to tell Twilight that all the mares in Ponyville were fillyfoolers, and the stallions were coltcoddlers. And then she was to invite her to join our little circle of lovers, but now you've scared her away and..."
Rarity tsked as she returned to work, leaving the rest of that sentence dangle as she continued to use the bound and gagged Rainbow Dash as a ponyquin. Perhaps the blindfold was a bit much, but it did so add to the feeling of power over Rainbow Dash that she was enjoying.
