A Twist in Reality

Screaming emitted into Applejack's ears. She sighed, hoping it would be over soon, but of course, she was wrong. The screaming continued before a tragic shout rang over the others.

"THIS IS THE. WORST! POSSIBLE THING!!!"

"SHE WAS SUCKED INTO A PORTAL!"

"Girls?"

"NO, I BET SHE BURST INTO FLAMES AND WAS ASH BEFORE WE COULD TELL WHAT WAS HAPPENING!"

"Uhm... girls."

"I BET SHE JUST EXPLODED!"

"Girls."

"OH NO! Wait, can ponies do that? Like, just randomly explode?"

"I bet they can! WE BLEW TWILIGHT UP!"

"GIRLS!"

Everypony turned to stare at Fluttershy. When Shy got loud, she was serious.

"You need somthin', sugarcube?"

"Uhm, do you girls remember what Applejack and Twilight were saying about the Elements of Harmony still being connected to us, but on the inside?"

Fluttershy gained four equally confused nods.

"And, uh, the little balls of light above us?"

"What're you getting at?" Rainbow Dash stopped the flapping of her wings, allowing her to drop to the floor, and stepped forward to poke Fluttershy's chest.

"Um, I thing they sent Twilight to the past."

"WHAT?!"

"Twilight Sparkle." The two familiar mares deadpanned.

Twilight was confused. Sunset Shimmer was... a pony again? Did the mirror open? It hadn't been thirty moons... had it? No, of course it hadn't. Pinkie had decided to be Twilight's personal calender.

And Trixie? Hadn't she been reformed? What was happening?

Although Sunset was friends with Twilight and the others now, she was still a bit weary of Twilight. She just had a bad feeling about her. This must be why! Twilight conjured her and this... Unicorn, here so that she could execute her evil plan! Sunset knew it!

Twilight shushed them and glanced around the library. "Girls, quiet."

"No!" Trixie sneered. "Trixie will have to refuse! Trixie demands to know what's going on here!

Sunset agreed, "Yeah! Why are we here?!"

Twilight shushed them once again and stood up straight, making a point of opening her wings to show her authority. While Trixie refused to acknowledge this, Sunset cringed.

"I'm not so sure myself," Twilight said, closing her wings. "I think it has something to do with my invention."

Trixie smirked and nudged Sunset. "Hear that? She thinks."

Sunset snickered to this, but with a simple glare from Twilight, she quieted. She may have been suspicious of Twilight, but this did not mean she didn't know her place.

"Look, I don't know what went wrong, but I intend to find out! Now would you both please just shut-"

"What's going on in here?"

"Up..." Twilight turned her head to see a Unicorn mare walking through the door. An extremely familiar mare. In a creepy way.

The three mares shrieked at the purple Unicorn with a baby dragon riding on her back who had walked through the door. She must have noticed the similarities between her and the Alicorn who stood in her library, because she shrieked back. The baby dragon had managed to slide off her back and step into the middle of the area between the two mares, holding his claws out to keep them from charging horns with each other. This did not, though, stop Trixie and Sunset from advancing onto Unicorn Twilight.

"You're a Unicorn!" Trixie exclaimed.

"But she's an Alicorn!" Sunset pointed at Twilight.

"How is this possible?!" Trixie wailed.

"There shouldn't be able to be two of them in the same point of time!"

"Now we have to deal with both!"

The two let out a joined wail.

Twilight and Twilight rolled their eyes, frowning.

In union, they spoke a flat-voiced, "Allow me to explain."
