Luna was happy. Here she was, eating a McDonald veggie burger, sucking at a chocolate milkshake and beating up creepers and zombies on Minecraft. Yep. She was totally happy.

All that happiness was destroyed as the door to her chambers burst open. A white guard - her sisters, to be precise, trotted up to her and bowed. Luna looked at him in distaste. She didn't know why Celestia chose those awful designs for her army uniform. Those helmets looked like they had just been struck by lightning, for god's sake.

"What?" Luna snapped at the guard. Those ponies annoyed her. All other ponies were fine. Just not those white and blue lightning rods. Why the heck were they even in her chambers? "Make it snappy."

The guard didn't even flinch. "Her highness, Princess Celestia, isn't in her chambers! We've looked all over Canterlot, and we couldn't find her!"

Luna rolled her eyes. "She went for a walk - duh."

"A walk so long that she ended up out of Canterlot?"

"Shut up." Luna shifted uncomfortably at how wrong-hooved she must have looked.

"With pleasure, your highness."

Luna thought for a moment. It surprised her that Celestia had gone somewhere without her precious, stupid lightning rods. "Yeah. She must have gone for a long walk. I don't think Celestia would have disappeared without a trace. I mean, there's a small possibility that Discord could have accidentally on purpose forgotten to perish those big thorns, but then they would have come after me as well."

The guard looked at her anxiously, taking off his helmet and putting it back on again. "Are you sure?"

"Quite."

"Beg your pardon, your highness, but why would the ruler of Equestria go for a walk all the way out of Canterlot without at least one of her guards?"

Luna smiled. "Don't worry, we all knew she was mental, didn't we?"

"...and that basically results in the fact that due to the sun being a star, it will someday explode." Twilight looked up from her research paper, brows creased behind her glasses in concentration. "Don't worry, it won't explode until ages - a few thousand millenniums, I should think."

Celestia was silent for a moment. "But it will explode." She said slowly.

"Yep. But not until a few thousand millenniums."

Celestia looked at her former student, her mind racing. Her sun was said to live forever. Somepony must have altered her sun. Somepony with power...and somepony who could control stars. "...Twilight, did you know that a millennium is, like, ten years for us immortal bodies?"

"No...?" Twilight's face suddenly sobered. "Oh. Oh."

Celestia stood up on her hooves. "Do you think you could give me a moment or two outside?"

Twilight smiled in a somewhat understanding way. "Of course, Princess. You know the way out." She watched the other Alicorn head for the exit.

"Oh, and Twilight?" Celestia turned around to address the purple pony. "You might want to get some earplugs."

Minuette was a normal unicorn, who lived a quiet life on the outskirts of Ponyville. She walked to the dentists everyday at six thirty in the morning every day to earn some bits, and had a colt friend in Manehattan. Her life was pretty good.

The spearmint unicorn levitated a poster up to the wall and fixed it in place. Minuette's shift had ended and Minty had taken over. Her boss had said she could help out by fixing some of the posters to make the place look even immaculate as it already was.

Just then, a high pitched scream crashed into her office, cracking a window slightly. Minuette flinched and staggered backwards. Was that...? That was Princess Celestia's voice, wasn't it? And was it her imagination, or had she heard the words 'Luna, I am going to murder you?'

Minuette shrugged and returned to her job. Everything was back to normal. Apart from the fact that somepony would have to come to fix the broken window. But that was it. Everypony knew Celestia was mental anyway.

Twilight gingerly took out the three balls of cotton that had been stuffed in each of her ears as Celestia came back down to the basement. "W-would you like some tea, Princess?"

"Celestia," She replied automatically. "And no thanks. I have a job to do." Celestia extended her wings and looked at Twilight pointedly, hoping she'd guess what her former mentor was going to do. But she had hoped wrong. Twilight just sat there with a bemused expression on her face, her purple wings unfolded slightly as well. Celestia would have slapped herself in teh face if not for her golden shoes. The perks of being a Princess. It was a shame Twilight never wore the pair of shoes Cadence had made for her. How ungrateful. She didn't even wear her crown! No wonder taxis didn't stop for Her Highness, Princess Twilight Sparklewhen she wanted one.

Whatever.

"Twilight," Celestia began. "I need to fly to Canterlot. My guards are at the castle and I want to pulv-"

"You can't fly to Canterlot." Twilight cut in. "If you forgive me for interrupting you, Pri- I mean, Celestia."

'No,' She thought, annoyed. 'I don't forgive you.' "Why ever not, my dear Twilight?"

"Because," Twilight explained. "What do you think would happen if all the ponies in Equestria saw a white Alicorn - namely, you - flying through the sky? Wouldn't the pegasi mob you as well? And you'd be surrounded by paparazzi!" She shuddered.

"Oh," Celestia was thrown. 'Yep. Twilight is a lot smarter than me.' "I'll go by train then."

Twilight sighed, the only thing keeping her from face - hoofing was the fact she was talking to the oldest Alicorn in Equestria. "Princess, Celestia, whoever, the problem will only escalate from there. Isn't it worse getting mobbed by all three pony species?" She smiled patiently. "Unicorns, pegasi and earth ponies will be on every single train we pass."

"...I knew that."

"Oh course you did!" Twilight declared happily. "You're the wisest and cleverest pony in Equestria!" 'Well, at least one pony believes that.'

"Ehem..." Celestia cleared her throat. "So what do you propose I do now?"

Twilight grinned. "Disguise!"

Celestia coughed into her hoof. "I still don't understand why you don't need to wear a disguise."

"Because," Twilight said patiently. "I'm a regular passenger on this train. You, on the other hoof, are not."

"Why the heck did you have to put this disguise on me?"

"Because it looks realistic."

Celestia had a pink coat and mane. Her hair was poofy and three balloons adorned her flank. Her blue eyes were half lidded and flashed in annoyance. Overall, she looked exactly like a Pinkie clone from the Mirror Pool. Except she didn't want to have fun. That was the only difference.

"I told you especially not to make me that pony. Why did it have to be her?" Celestia huffed grumpily. "Couldn't I have been a regular dentist or something?"

"She had the simplest mane. You just sleep in bed for a few hours and you look exactly like Pinkie Pie. The others were too hard to get. Also, to answer your question," Twilight continued. "I normally board these trains with one of my friends. You know, friends I hang out with regularly."

A couple passed by and looked at Celestia with a strange look on their face. They carried on walking, but kept on throwing worried glances at her. She glared at them. "What're they looking at?"

Twilight sighed. "You have to look happy. And you need to bounce."

Celestia turned her glare on Twilight, who just grinned. "C'mon, this'll be fun!"
