I am so, so sorry. I had not realized the major plot hole in chapter 7. When I edited the chapters on the website, I had thought when I saved them, the chapters had saved and you guys could read my changes. Again, I am sorry.
The three ponies arrived at the train station, Celestia and Luna both very much out of breath. "Apologies." Luna said, puffing as she sat down. "We are not used to running around."
Celestia sat beside her and asked Sunset to go find out if Twilight had come by the station yet. "Excuse me sir," Sunset said as she walked up to the ticket booth. "Has a young unicorn with a baby dragon come by here recently? She has purple fur, and no Cutie Mark. As well as she looks almost exactly like the Princess of Friendship." The ticket master looked up sharply.
"Why yes, she did!" He said, very gruffly. "She passed herself off as the Princess and boarded the next train for Ponyville. I noticed that she wasn't the Princess but, the train had already left the station."
"How quickly can you get me three tickets to Ponyville?" She asked.
"Well… the ticket master said, leaning back in his chair. "That depends on who's asking."
"How about two Princesses?" Celestia said, walking up behind Sunset with Luna in tow.
The ticket master got up and quickly grabbed three tickets to Ponyville, handing them over with the utmost care. "Here you go, your Highnesses." He said, bowing as he levitated them over the counter.
"Thank you, sir." Sunset said coldly. "Next time think before trying to stiff two Princesses."
The trio trotted into first class and sat down as the train left the station. "Looks like we have a long ride ahead of us." Sunset said, curling up on one of the chairs. "Might as well make the most of it."
Midnight walked onto the train station, and was greeted by the Tri-Pies getting ready for a race. "Wow," She thought, looking at their manes, tails and fur. "They must be triplets or something. I can't tell them apart." The Tri-Pies took off, never noticing the blank flank duplicate of their aunt.
Midnight walked into town. "If I look like the Princess in this town, it might cause more attention then I want." She thought, looking down at herself. "If I'm a unicorn, then I must have Magic right?" She concentrated hard and, in a flash of purple flame, changed her coat to a deep magenta. "Not bad for a first try." She said, walking out of an alley and into town. "Maybe now I can get some answers without ponies looking at me funny." She walked past Sugar Cube Corner, where those same three fillies where sitting on the steps; licking ice cream cones, and catching their breath. They all looked up at the same time and inhaled sharply. Jumping up in the air, they quickly sped off to some unknown location.
"Well, that was certainly interesting." She said as she trotted away. "I would've thought that only Pegasi could fly." She walked down the street and, passing the spa, she heard a loud clatter. Going around the back, she caught a yellow Pegasus kissing an orange stallion and a garbage can lid rolling around. She recognized the Pegasus from the Gala, and realized that she probably shouldn't be here. She turned to leave when she heard somepony say, "Fluttershy?!"
Midnight turned back towards the group to see an orange mare with freckles and a cowpony hat staring in shock. She quickly hid behind a cart, determined to see where this went.
The Pegasus pushed the stallion away to look at the stunned cowgirl, rolling her eyes in annoyance.
"Uh, hello?" She said, sounding very angry. "Do you mind?"
She was about to pull the stallion in again when the cowgirl cut in between them.
"What is this?" She demanded. "Who is this? What about Discord?! And Screwball and Zany?!"
The Pegasus named Fluttershy scoffed. "They'll be fine, so long as they don't find out. And if they do, they'll get over it."
The cowgirl stood still, momentarily stunned. She shouted, "What's come over you?! Do ya have any idea what Discord will do if…"
"Move aside, will you?" Fluttershy snapped, shoving the cowgirl away. "We're in the middle of something."
Fluttershy pulled the stallion back in and Midnight looked away, unable to watch anymore. She didn't know who Discord was, but he was not going to be happy.
The cowgirl ran out of the ally in tears and Midnight decided to follow her; see if there was anything she could do to help. The cowgirl ran down the street, right past the living zoo, who stopped her with his paw. "Whoa there, cow girl." He said, sounding a lot like Q. "What's the rush?"
Midnight saw her mutter and respond, "Oh, uh, howdy partner! I was just, uh… I have to, uh… I left the bathwater runnin'! Yeah, I gotta get home, see? So, uh… bye!"
She galloped off, almost away when the Zoo grabbed her by the tail and lifted her up.
"Element of Honesty, huh?" He said, smirking. "What's really troubling you, AJ?
Midnight leaned in, trying to hear better.
"Uh… I don't really wanna talk about it!" She said, sweating nervously. "Plus, it doesn't concern you!"
The Zoo shook his head. "You know I can always just peek into your head and discover what you're hiding?"
"No!" The cowgirl shouted, kicking her legs and trying to escape. "You're not gonna like it!"
"Ooh, that juicy, huh? This is gonna be fun!"
"Discord, trust me on this! You don't wanna…"
"The more you say that, the more I do wanna."
It was at that moment that Midnight registered the creature's name, and, more importantly, what the cowgirl was trying to hide. She jumped out of the bushes as Discord placed his claw on her temple, and the two stood there frozen as Midnight tried desperately to get their attention. After several minutes of trying to get their attention, Midnight gave up and decided on a wiser course of action. "I have to find someone who can help." She said as she galloped towards the nearest building.
Sunset Shimmer stepped off of the train and beckoned the two sisters. "Come on, this is our stop."
Luna stepped out, closely followed by Celestia who looked very sick. "Ohhh." She moaned, stumbling out of the train car. "That is the last time I take the train." She leaned over the railing and puked.
"Come now sister, we must find this doppelganger and return her before it is too late."
"Luna is right, Princess. We must hurry. Luna, you go check Sugar Cube Corner and go from there."
"WE SHALL DO OUR BEST!" She announced.
"Celestia, you take the library. You know Twilight well so you should know where she would go from there."
"Of course."
"And I will check around the Everfree forest. If anything, she will be over there. And I could always ask Discord to find her. And we all know the Cutie vibrate right?"
"Yes, we do."
"Yes."
"Alright then, just light up the others Cutie Marks with your magic if you find her. We will come to you right away. Now let's go."
The trio split up and went to look for her.
Luna galloped at full speed towards Sugar Cube Corner. When she got there, she trotted through the door.
"Surprise!" Shouted Pinkie Pie, Red Shoes and the Tri-Pies. "Oh, sorry girls," Said Pinkie, turning towards her daughters. "That's not her either."
"Aww." The Tri-pies said, looking dejected.
"Sorry we had to interrupt." Luna said looking around. "We are looking for someone."
"Who?" said Pinkie.
"Twilight's Doppelganger fell through the portal, and we're trying to get her back."
"Wait," She turned to Blueberry. "Blueberry, didn't you say that she looked like Aunt Twilight, except with brighter fur?"
"Yeah, just like her! Why?"
"Did you see which way she went?"
"Ooh, ooh, ooh! She was walking towards the spa." Raspberry said, bouncing up and down.
"We must go there right away!" Luna said as she galloped out the door again.
Sunset walked towards the entrance of the Everfree forest. "Uh, Oh great and ancient forces of Chaos, show us the path that shall lead us through! Cotton candy and chocolate of rainstorm and snow, take me to the Castle of the Sisters Two!" She stared at the forest, but nothing happened. "Huh, I guess Prism pranked me again. Okay, how about this. I'd like to visit Discord please." The forest split open to reveal a path straight to Discord's castle.
"Well, that was easy." She said as she walked through. "I just hope he's in a good mood."
Celestia walked into the library to find Princess Twilight reading. "I would have thought you finished everything in here." She said, glancing around.
"Princess Celestia? What are you doing here?" Twilight said, standing up in shock.
"Trouble, I'm afraid. You are aware of your friends at Canterlot High."
"Yes, I remember them well."
"I'm afraid your doppelganger has fallen through the portal."
"Well that can be remedied easily. But I'm not sure why I would want to."
"What do you mean?" Said Princess Celestia, looking confused.
"I mean I don't take orders from you. In fact, I think Queen Chrysalis will promote me to General when she finds out I caught a Princess."
"What!"
In a flash of green flame, Twilight transformed into her real form, a changeling who immediately shot a green laser at Celestia, encasing her in the green liquid.
"Now I just have to call her and the promotion is mine." He turned around to face her. "It's best you're not awake for this." He said, and as his horn glowed bright with a sleep spell, he turned to make his call.
Sunset walked up towards the Castle of Chaos to see cotton candy clouds zooming around, making brown puddles everywhere. "Wow," She said, staring at them in shock. I didn't know that was actually possible. He must have gotten into a fight with someone again." As she walked towards the castle, she wondered who it could be. "Maybe Screwball? She would be around the fighting age. I don't think Zany would have caused a fight. He's five years old for heavens sake." She stopped to find the door open. "Wow, I've spent too much time on Earth. I'm starting to sound like one of them." She walked in to find Discord and Fluttershy arguing.
"…Each other for all eternity, I assumed you would do the same!" Discord said, eyes ablaze.
Sunset looked slowly around the corner, and saw Fluttershy blink in confusion.
"What are you talking about?"
"But that was never enough for you, was it? Was it!"
"Discord, I don't…"
She squealed as he grabbed her foreleg.
"Who is he?!"
"Discord, you're hurting me!"
"WHO IS HE?!"
Sunset thought she should intervene, but she also did not want to be an orange for the rest of her life.
"He?" Fluttershy said, looking at him in confusion.
"That stallion! The one that you were playing tonsil hockey with!"
Sunset's eyes widened. Fluttershy would never do that.
"What?! Discord, I don't know what you…"
"You were kissing him! I saw you!"
"Discord, I… no! You're the only one I've ever kissed!"
"Don't play innocent with me! I saw you! Applejack saw you! You calling Applejack a liar?!"
"What… I…"
He let go of her leg and lifted her up by her necklace.
"Does this mean nothing to you?" He bellowed. "After everything I've done for you, after having my children, this is how you repay me?!"
"Discord, please." Fluttershy begged. "There is no other stallion! My heart belongs to you!"
"Oh, is that so? And what about the rest of you?!"
"Discord!"
Sunset didn't know who to believe. Applejack was the most honest person she knew, but Fluttershy would never have an affair. She couldn't think of any other way.
"Discord, you have to believe me! I love you and only you!"
He dropped her on the floor and turned away. Sunset could not bear to watch any more, she turned around too.
"Apparently, you didn't love me enough!" He said, and Sunset heard something clatter to the floor. "You will regret this! YOU ALL WILL!"
There was a burst of light and a wave of heat. Then nothing. Sunset ran out of the castle, determined to find out the truth, as she could not bear to hear Fluttershy cry.
