Author's Notes:

Princess Twilight is the equestria one, and Twilight is the human one.

"Ugh," groaned Sunset Shimmer. "Why does Rainbow Dash always have to show off?" she thought. Rainbow Dash had been showing off to the Cutie Mark Crusaders when some of here guitar strings broke, and now she had sent Sunset Shimmer to get some more. When she got to the nearest music store (which was a few blocks away), she went straight to the guitar section to look for some strings. Only problem was that there weren't any there. So she asked the person that was working at the front desk.

"Excuse me, do you have any guitar strings here?" she asked.

"Yeah. How many do you want?"

"Three, please," she said. The clerk put the strings on the desk, Sunset Shimmer paid, and while leaving the building, accidentally ran into someone.

"Oh my gosh, I am so sorry," she said.

"Don't worry, it's o......" She stopped there, because this other girl looked exactly like her. Except for the hair and the clothes, they looked like they could have been twins.

"Um, who are you?" the other girl asked.

"My name's Sunset Shimmer," she said.

"Seriously? My name is Sunset Shimmer. Is this some kind of joke?" she asked.

"No. Oh man, I've finally found you" the equestria Sunset Shimmer asked.

"Um, what?" the human Sunset Shimmer asked.

"Look, I'm going to need you to come with me, ok?" The equestrian Sunset Shimmer said.

"Um, ok, why?" the human Sunset Shimmer asked.

"If I tell you, you aren't going to believe me, ok? And I need my friends to back me up," the equestrian Sunset Shimmer said.

"Ok, but can't you tell your friends to come here?"

"Yes, but the portal is over there," the equestrian Sunset Shimmer said.

"Portal?" said the human Sunset Shimmer.

"Yes, portal. Now hang on a second, I have to contact my friends, and then see if Princess Twilight can come, and see how soon she can come," said equestria Sunset Shimmer.

"Seriously, this is crazy!" said Rainbow Dash.

"Rainbow Dash, don't be rude," said Fluttershy.

"Sorry, but this is as crazy as when we found the other Twilight, no offense," said Rainbow Dash

"None taken," they said at the same time.

"Ok, do you all really expect me to believe that a pony princess from another world is going to come thru the mirror," human Sunset Shimmer asked.

"Portal, and yes, a bit," said Rainbow Dash. As if on cue, Princess Twilight came running thru the portal.

"Hi guys, I came as soon as I could. What happened?" she asked.

"I happened," said human Sunset Shimmer.

"Sunset Shimmer, why are you dressed like that?" Twilight asked before noticing her Sunset Shimmer sighting next to here.

"Oh, never mind. So you're the Sunset Shimmer of this world?" she asked.

"Yeah. You guys were actually serious about that?" human Sunset Shimmer said.

"Yeah. Ah don't believe in lying to people," Applejack said.

"Well of course you don't. In my world you represent the element of honesty," Princess Twilight said.

"Yeah, that's pretty cool and all, but we need to PARTY!!!!" yelled Pinkie.

"Pinkie, we do not need to party. At least not yet, anyway," Twilight said.

"Oh. Ok," said Pinkie.

"When did you meet?" asked Princess Twilight.

"About an hour ago, in front of a music store," said human Sunset Shimmer.

"Wow, what are the odds?" asked Rarity.

"I know right?" asked equestria Sunset Shimmer.

"So, this has happened before, right? I mean besides you two," said human Sunset Shimmer, indicating Princess Twilight and human Twilight.

"No, not yet. If too too many people from different worlds meet, the results could be catastrophic," said Princess Twilight.

"Wow, you are really smart," said human Sunset Shimmer.

"Was there ever any doubt?" asked Princess Twilight.

"Well, a little bit," said human Sunset Shimmer.

"Really? Whatever, we have more important things to deal with. You two and both of our worlds will be relatively safe as long as you don't touch. Have you already touched?" Princess Twilight said, suddenly very suspicious.

"A little bit. Don't worry, we'll probably be fine as long as we don't touch too much," said human Sunset Shimmer.

"Or if you touch with skin. Did your skin touch when you last did?" said Princess Twilight.

"Um, no, I don't think so," said equestria Sunset Shimmer. "But it's probably like what she said, and that we're probably good as long as we don't touch too much." Princess Twilight didn't look to happy.

"Ok, but just in case, don't touch unless you absolutely have to, and even then, don't touch each others skin. Extremely bad things could happen, and I don't think anyone wants the world to end, in your world or mine. So please, be careful. Sorry, but I think I have to go now," said Princess Twilight. "There was quite a bit of work that I had to get done when Sunset Shimmer contacted me, and this was a considerable amount more important than some of the paper work that I have."

"Are you sure?" asked Pinkie. "There's going to be a party!"

"As much as I want to stay for that, I'm sorry, I can't. Being a princess isn't what the stereotype is like at all," said Princess Twilight.

"Ok, dang it," Pinkie said.

"Well, bye!" Princess Twilight said cheerfully. "I'll see you soon!"

"Bye," the other girls chorused. A few seconds after she left, human Sunset Shimmer turned to her counterpart and said, "Wow, she's a princess? What were you in that world?"
