Welcome back people! Well, in the last chapter, we ended with Rainbow Dash and Pyro finding out that their cutie marks are the same. I know you guys want to just get to reading the story, so I will end with Disclaimers: I do not own My Little Pony or anything related.

Both ponies stared in complete confusion at each other's cutie mark. There was nothing but complete silence for a while, but finally Rainbow Dash broke the silence. "I thought that a cutie mark was supposed to be something that separates you from every pony else, something that makes you individually special."

Pyro looked at her and said, "I thought the same thing…"

"Let's go to Twilight's. She knows a lot about these sorts of problems." Pyro nodded and they both trotted down to Twilight's library. When they got there, they knocked on the door and were greeted by Spike. "Spike, is Twilight here," Rainbow Dash asked.

"Yeah, she's in her room on the top floor… May I ask why you need to see her?"

"Sorry little dude, but that is classified." Spike grunted and mumbled something, they couldn't make out a word of what he said, and then moved out of their way. They both headed for Twilight's room. When they got there, they found Twilight reading a really big book. Rainbow Dash wasn't surprised, but Pyro looked as if she never seen a book that big before. Twilight looked up from her book.

"Well, hi girls, what brings you here?" She got up and used her magic to bookmark and close the book she was reading.

"Twilight, we have to ask you a weird question." Twilight looked at Rainbow Dash with a questioned look in her face.

"What sort of weird question are you talking about?"

"Well, have you read in any of your books about two ponies with the same exact cutie mark? Like exactly the same, down to the last detail."

"No. I have read, though, that it is physically and magically impossible for that to happen. Why such the sudden interest in cutie marks?"

"Um, well, it's kind of hard to explain, so I guess we'll just show you."

"Show me what?" Rainbow Dash and Pyro both showed Twilight their flanks and revealed to her their cutie marks. Twilight stared in complete horror at the two ponies. The other two didn't like the reaction they got from their friend, and started to get a little worried.

"What is it Twilight," Pyro asked. She will soon regret having asked that question soon after. "What is it? Stop staring at us like that!
"Yeah Twilight, you're freaking us out," Rainbow Dash added.

Twilight soon gained enough sense to actually speak. "This isn't real, is it? You two are joking with me, right? Is that a sticker on Pyro's flank? This isn't funny, ponies!" Twilight was oddly enraged at this, and also looked really sad. She had tears in her eyes as she started to yell at them.

"Twilight, why are you getting so mad? And why are you crying? What does this mean?" She didn't get an answer. "Twilight, answer me!" Now rainbow Dash was yelling.

"Rainbow Dash," Twilight started, "I need to speak to you. Alone, please," she said looking at Pyro. She understood and walked back down stairs. Rainbow Dash walked closer.

"Why do you only need to see me? Pyro and I both have the same problem."

"No, Pyro is the only one with a problem."

"What is that supposed to mean," Rainbow Dash asked, obviously offended at what Twilight had said about her cousin.

"She can't be here, she doesn't belong here!"

"Twilight, Stop talking like that! That isn't how you usually talk. What's the problem?" Twilight looked really tense, and seemed to be a little shaky.

"That pony isn't your cousin Rainbow Dash…"

"What are you talking about, of course she is. She showed us all proof, remember?"

"I know, but that isn't real either. Nothing about her is real."

"Twilight, please tell me why you're acting like this."

"Rainbow Dash, I am really sorry, but like I said before, she isn't your cousin."

"Then who is she Twilight! Answer me, now!" Rainbow Dash was starting to get really angry.

"She is you," Twilight yelled, shutting Rainbow Dash up. "She's from another dimension!"

"Twilight, you're talking nonsense."

"No, Rainbow, I am talking the truth! Pyro isn't who she seems whether she knows it or not."

"I don't want to believe that, but I guess it's the only way to get some information, so, what did you mean when you said she was me?"

"What I meant is she is you in her dimension, except the complete opposite of you in every way."

"How do you know that?"

"What they say is true. A cutie mark represents something special about an individual pony based on what the picture is. She shouldn't have the same cutie mark as you, and she shouldn't be in this dimension."

"Well, if what you say is true, how did she get into this dimension?"

"Well, I don't exactly know, but we need to find out and send her back before she causes some serious damage to Ponyville."

"Wait, Twilight. Before you start saying anything like that, I need to know for sure that you're right. Please, if you have any proof, I need to see it now." Twilight nodded and motioned for Rainbow Dash to follow her. She led her near her bed, and she searched under it. There, she grabbed a small book. It wasn't as big as any other book she had in the library.

"Well, rainbow Dash, here's your proof." She dropped the book at Rainbow's hooves. She read the cover, "Cutie Mark Doppelgangers". She opened the book to the first page, and immediately she sensed something was wrong, because as soon as she opened the book, there was a warning sign behind the cover. It read, "Warning: If you or anypony else knows another pony who has the same cutie mark as you, they need to be removed-"There was more, but the words were faded away. She kept on looking over the book, skimming through the pages. When she finally reached the end and closed the book, she looked at Twilight. Rainbow's facial expression was completely mournful. She looked as if she had just been stabbed in the back by one of her closest friends. Except this friend wasn't even a friend, it was her evil self.

God, I'm sorry for the extremely late chapter guys. Well, what did you guys think of chapter three, a suspenseful way to end a chapter, eh? Well, I have to get started on working on chapter four, so I guess I'll see y'all next chapter!
