The sun was shining from the window into Rainbow and Applejack’s room. They were both in bed, sweaty and in need of a shower. As Rainbow got up, she saw Applejack was still sleeping. She walked over to the bathroom quietly then took a nice cold shower to wash off all the "sweat" from her body. As she walked towards the shower, she looked at the stump that used to be her Left-Wing in the mirror and remembered she had promised Applejack she would try to fly today.

"Ugh...Why does life have to be cruel sometimes?" Dash groaned she walked into the shower and turned the water on. As the water hit her fur, she stood there thinking about all that had happened. With Spitfire in the hospital from the attack, she could not rely on her for backup, Twilight was not back from the Mirror Dimension yet, and Luna and Celestia were busy finding Princess Cinch and the Shadowbolts’ hidden cave.

Once she got out of the shower, Applejack was waiting for her in the bathroom. "Hay, beautiful. Have a nice shower?" Applejack asked.

"It wasn’t the same without you in there with me," Rainbow said.

Applejack had a big smile on her face. As she got into the shower, Rainbow Dash left the room to put her metal wing on. While it would take some getting use to, she could live with it for the time being. Who knew? With a few adjustments and an awesome paint job, it could look as good as new. Rainbow used all her strength to lift the wing onto her back, then attached it to her waist and strapped it on.

She walked towards the mirror and looked at herself. "It's not that bad, is it?"

"No… Not at all, Dashie," Applejack said. "I have a lot of work today. And you have a personal trainer to see," Applejack said

"Ugh, do I have to?!" Rainbow complained.

"If you want to fly and beat Lightning Dust, then yes, you do," Applejack said.

"Okay.,"

"Love you!" Applejack said.

"Love you too," Rainbow said. She then walked towards Ponyville for her training with her personal trainer, Time Turner, or as others called him, Dr. Whooves.

The TARDIS

Dr. Whooves was a strange pony. While he looked like a regular pony on the outside, he was definitely not one on the inside. He was an alien from a planet called Gallifrey in another dimension like the mirror, except "less cute and more extreme," as Dr. Whooves would say. People knew he was not from around Ponyville, but they did not care: he was nice, funny, and had many fascinating stories to tell from his travels.

As Rainbow entered the police box, she mused, "I know this is not magic, but this is impressive stuff, even for an earth pony."

"Ah...Mrs.Dash, welcome!" The Doctor said. "I presume you’re here for training."

"Yes Mr. Whooves," Rainbow said.

"Please" The Doctor said. "Just call me The Doctor"

"Ok… Doctor, where exactly are you taking me to train?" Rainbow asked.

"Well," The Doctor explained, "since your flight camp was destroyed, I was thinking, how about going in time before it was destroyed? But then I remembered that it’s always in use, so you would be spotted for sure. But then I thought, how about we go back to the Golden Age of the Wonderbolts, when Spitfire herself was still in camp? So that's where I’m taking you."

"So I’m going to time travel!" Rainbow said, excited.

"Yes indeed," The Doctor said.

Just then, the TARDIS began to make noise and Dr.Whooves said something that sounded Old Ponish

"Allons Y!" The Dr shouted

Wonderbolt flight camp 1986 BMN (Before Nightmare Moon)

As Rainbow exited the TARDIS, she saw the flight camp and was astonished to see what was in front of her: all the buildings looked new the grass freshly cut and the runway paved to a perfect code of black

"Thank you, Doctor!" Rainbow said hugging him

"No problem, Miss. Dash," The Doctor said. "Now remember, there are three things you cannot say to anypony: One, your name; Two, what happens to them in the future; and Three, most importantly, Don't Change The Future By Telling Anyone What Happens To Them!

"Yes, sir!" Rainbow said. She then ran towards the flight camp.

***

As The Dr entered the TARDIS with Rainbow, he could see that she was all sweaty and exhausted. "And I thought Spitfire was a tough teacher," Rainbow said.

"Well, hopefully, you now know how to fly using that metal wing of yours," The Doctor said.

"Yes, I do," Rainbow said. "And I’m now faster than ever before."

"Good," The Doctor said. "Now let's get you back to your time zone.”

As the TARDIS made that noise again, Rainbow was burning up with a question for The Doctor and could not wait for any longer to ask it. "Doctor?" Rainbow asked. "Will me and Applejack make it through what is happening with Lightning Dust?"

The Doctor froze. "I’m sorry, Rainbow. I’m not allowed to tell you your future," The Doctor said. "I can only tell you this… You will both have great happiness and sorrow that is yet to come."

"Will...Will Me or Applejack die?"

"Sigh... No… No, You Both will not," The Doctor said. "That is all I can tell you."

The TARDIS grew silent. When the door opened, Rainbow could see Sweet Apple Acres.

"Now usually I would come to explain why we were late," The Doctor said, "but we can't stay here."

"Why, is something bad about to happen?"

"No, not at all… Well, you will see, or rather you will hear."

"Okay then… Well, I hope to see you soon, Doctor," Rainbow said.

"Oh, trust me, you will see me very soon," The Doctor said.

As Rainbow Dash exited the TARDIS, the box slowly began to disappear, until just like that, it was like it was not even there.

"Wonder what he meant by that?" Rainbow Dash thought to herself as she heded to her loving wife waiting for her at the barn

Twilight’s Castle 1 hour later

As the Main 5 stood in front of the Mirror, they were expecting Twilight and Sunset to come through it any minute now. It had been two days since she had gone into the mirror, and they all were getting worried.

"Do you think she was held up?" Rarity asked.

"This is Twilight we are talking about! I think she can take care of herself," Applejack said.

Just then, a noise filled up the room that nopony recognized--nopony except Rainbow Dash. All of a sudden, the TARDIS appeared in front of the mirror.

"Okay, I think this is the right place," The Doctor said.

"Thanks again, Doctor," Twilight said.

"Hey, girls!" Sunset said.

"Umm, hay," Applejack said.

"Doctor, what are you doing here?" Rainbow said.

"I’m sorry, do I know you?"

"Um, it’s me, Rainbow Dash, remember?" Rainbow said, confused. "You just recently took me to.."

"Stop what you are saying right now!" The Doctor said. "Sorry if I’m sounding rude, but it’s dangerous to know too much of your own future, especially if you are me."

"Then who took me earlier today?"

"Easy--the Doctor you saw was my future self. He had already done this, so he knew that he could not stay."

"I guess that makes sense?" Rainbow said.

"Good! Now if you’ll excuse me, I must be going. Well, see you soon, or in the future, or maybe the past… Time travel is so confusing," The Doctor said, laughing to himself. As he closed the door, the TARDIS made that sound and disappeared into thin air just like last time.

"Umm, why did The Doctor take you here?" Applejack said.

"Long story," Twilight said.

"You would not believe us even if we told you," Sunset said.

"Yeah, that whole time travel thing was really confusing," Twilight said.

"I do, however, have something to tell you all that is less confusing," Sunset said. "Princess Cinch lived in my dimension for quite some time under the name Principal Cinch."

"She was?" Luna said

"Yes… she even took the Twilight of my dimension and turned her evil for a couple of minutes, but I beat her," Sunset said. "After that, we never saw her again. I assume she came here afterward."

"If this is true, then we can use this to our advantage," Princess Celestia said.

"And do what?" Applejack asked.

"Make a plan," Luna said.

"As far as we know, she is unaware that Sunset is the Seventh Element Bearer, and furthermore that she is even back in Equestria," Luna said.

"So when do we get to kick some flank?" Rainbow said.

"For now," Celestia said, "we have to wait for them to make their move. Only then we can make our own."

"What is the plan?" Twilight asked.

"Oh, I hope it involves a party!" Pinkie Pie said as she walked in the room with Starlight Glimmer following behind her.

"We're back," Starlight said.

"Starlight, Pinkie, how was your trip to Seaquestria?" Twilight asked.

"It was okay," Starlight said. "I still can't get used to swimming instead of running," Starlight said, smiling. "So what did we miss?"

"I think it's best if you tell them what happened, Rainbow," Twilight said.

As Rainbow Dash walked out of the corner she was standing in, Pinkie Pie and Starlight Glimmer went from happy to sad. As she explained what had happened so far--the attack at the gala, the proposal, the attack on the Wonderbolts--they were quiet the entire time.

"I'm so sorry, Rainbow. It must be so hard for you to..." Starlight said before getting interrupted by Pinkie who had frozen with a giant smile on her face once Rainbow had told her about proposing to Applejack.

"Oh my gosh! You and Applejack are getting married! I’m so excited!" Pinkie Pie blurted out before realizing she was interrupting a serious conversation. "Oh, sorry."

"Anyway, seeing that metal wing is familiar, though," Starlight said.

"What do you mean familiar, Starlight?" Applejack said.

"Well remember when I was evil, and I tried to rewrite the timeline by making sure Rainbow Dash wouldn't win that big race?"

"Yeah, I remember," Twilight said in a sarstasisic tone.

"Yeah, well, when I traveled in time the first time and came back, I came across an Equestria at war with King Sombra. During that war, you had lost a wing, and it had been replaced with metal. You were also fighting alongside the Wonderbolts," Starlight said.

"I was?" Rainbow asked.

"Yes... you were even fighting a stranger who kind of looked like you," Starlight said.

"Did this mare happen to have a lightning-colored mane and a light blue coat?" Princess Celestia asked.

"Yes, actually; why?"

"Then our worst fears have come true," Luna said.

"Why, what’s wrong?" Twilight asked.

"I'm afraid that wasn't an alternate dimension you saw," Celestia said. "Instead you accidentally traveled into the future, and what you saw was the future."

"But I went to this future as well," Twilight said, "and when I approached the Applejack from that future, she said she had no idea who any of our friends were."

"Most likely a side effect from time traveling," Luna said. "There was most likely a time quantum loop from when you traveled there, and so pieces of her memories were probably gone. Did she remember any familiar names by any chance?”

"She said the only name she remembered was Rarity," Twilight said.

"If she even remembered one of The Element of Harmony Bearers, that means it was definitely a quantum loop," Celestia said.

"So if what I saw was true, that means..." Starlight said.

"King Sombra is going to return, and there will be a war."
