"Okay Trixie, now this next spell is very difficult, it took me years to master, but I believe you can do it," Twilight told her new friend Trixie.
Ever since she had made friends with Trixie, she had gotten her away from using her third person way of talking and more of a first person. Trixie agreed to it since she had heard how much ponies were disliking her boasting and using her name in every sentence when she referred to herself. It had taken a while, but now everypony had forgiven Trixie for the past and welcomed her as a friend. Twlight had been training Trixie on how to use her magic, with Princess Celestia's approval, saying that sometimes the student has to become the teacher themselves, and Twilight now knew she had in the past, without even realizing it before hoof.
Princess Celestia also stated to Twilight that Trixie herself had great potential and wished she could have found Trixie sooner to train them along side each other. Trixie had learned fast from Twilight and agreed she would do her best not to show off what she learned, but use it if and when needed. Today Twilight was teaching her a spell that was extremely difficult and Twilight herself had a few mishaps before preforming it right. She was teaching her how to Teleport long distance, which many unicorns their age could only imagine. She warned her that this will cause a good headache, since she herself rarely used it unless it was emergencies. Trixie still had a bit of stubbornness to her and said she was ready, wanting to test her limits. Twilight chose to have her teleport to Canterlot, since she felt the Crystal Empire was too far.
"Okay, so I need to focus on where I am going in order to get there without any mishaps?" Trixie asked.
"Yes, if you don't, you could end up deep in the ocean or high above the clouds, and trust me, that's a truly terrifying experience," Twilight answered.
"Okay, Pony Joe's doughnut shop sounds like a good spot to go to," Trixie said.
"Great option, we can have our favorite doughnuts once I arrive behind you. Now, one last time are you sure your ready for this? I've already warned you about how difficult it is and that it may cause headaches afterwards, but I have every bit of confidence you will succeed," Twilght stated.
"Well, I did have the best teacher next to Celestia herself, so yes, I do feel I am ready," Trixie stated, complimenting her friend and teacher.
"Alright, start concentrating on your magic and focus on where you will be going. I'll be here in case you need help," Twilight cautioned.
"Okay, here we go," Trixie said.
Trixie soon pictured the place she wanted to go and started to produce her magic. Everything appeared to be going good. "That's it Trixie, your doing good keep going," Twilight cheered.
Trixie kept going making sure she would have the right amount of magic. "Okay I'm almost there," Trixie said.
"That's great, soon it'll be enough to teleport to Canterlot," Twilight told her.
Trixie felt she now had enough and replied, "Okay now to teleport to, wooow, what the, my magic I can't..."
Trixie's magic had started to spike beyond what she thought she was capable of and out of her control. "Oh no," Twilight said, now nervous for Trixie. Trixie tried to regain control while Twilight came towards her and said, "Hold on I'll help you get it..."
Before Twilight could utter another word, no pony, not even the Princesses were prepared for what happend next. Both the lavender unicorn and her sky blue unicorn friend were struck by the magic and screamed before they were rendered unconscious.
As Twilight and Trixie awoke they both felt light headed, and were somehow laying on their backs next to each other, eyes still shut. "Oh, my head, sowwy Twiwight," Trixie said.
"It otay I sowt of distwacted you," Twilight stated and opened her eyes before she said, "Now why evewything so dawk, and why I tawk funny?"
Trixie opened her eyes to, and looked around as well. "I not know, but I feew diffewent. Is that how speww supposed to mwake you feew?" Trixie asked.
"No, which is odd, becauwse I feew diffewent too," Twilight answered.
Soon they heard voices coming from what appear to be a room next to wear they were. The voices sounded to be all too familiar to both the unicorns, and they were able to make out, "Oh, sound's like their awake, I better go in and check on them."
They realized it sounded just like Luna when she wasn't around her other subjects. Their thoughts were confirmed when the door opened and Luna's shadow appeared as the light from the next room showed her figure coming in. Before they were able to notice anything else, the light's were turned on and the girls covered their eyes from the sudden change in brightness. When they pulled their hooves away, what they saw shocked both of them beyond reason. They had bars on either side of them, which led them to conclude they were in a crib. But that is not what baffled them most. Luna was looking down at them with what could only be described as, a maternal smile on her face, and not only that, now she looked like a giant to them. When they looked at each other, they were in even more shock. "You'we, you'we a foal," Trixie stated.
"So...so awe you," Twilight said back.
"Oh, my little angels of the night are talking to each other, you are so adorable when you do that," Luna said before she bent down and nuzzled them.
Twilight and Trixie felt weird about what she just said, but as soon as she nuzzled them, they felt safe and content, which they found odd, but they didn't want it to end. After the nuzzling was over, Twilight rolled onto her belly and soon felt a wetness on her flank. She realized she was wearing a diaper and must have used it. She was going to say, "Luna I have a wet diaper," but what came out shocked both her and Trixie. "Mama my diapie wet," Twilight said making her surprise herself she said mama instead of Luna.
Luna smiled as she cooed at the fact Twilight said Mama, and seemed to be the only word she said according to what Luna heard among the baby gibberish. "Oh did my little Twiliy get her diaper all wet? It's okay, you and your sister Trixie are only two weeks old. Don't worry, Mama is gonna change her little angels of the night right now," Luna said
Twilight and Trixie were soon lifted up in Luna's magical dark blue aura and were being levitated to what they knew was a changing table. Soon Luna set them down and started to change both at the same time. As she did the two unicorns thought to themselves. Twilight had called her mama and Luna was even acting the part. They both looked like foals and they were wearing diapers. 'Why did I call Luna "Mama"? And how are we foal sized and wearing diapers, I know we are both stable trained, and that does not explain my diaper being wet and why did she call us her "angels of the night"?' Twilight thought to herself.
Luna seemed to be out of character to them, and they wondered why, especially why they seemed to understand each other but Luna couldn't. 'It's as if we really are foals, but we are still thinking like grownups and are able to talk to each other, but why can't mom, no, Luna understand us?' Twilight asked in her head.
They started to look around the room and it looked like Luna's room only nursery style with the crib, toys, and everything foalproofed for foals. Twilight then noticed something that she could not explain, there was a picture of her and Trixie being held in Luna's arms and she was nuzzling them in the picture and all three were smiling.
This confused Twilight greatly. She knew for certain that even when she and Trixie foals before now, Luna had been on the moon serving her banishment as Nightmare Moon, but this picture clearly showed the three of them together. Then it hit her. 'Mama, no, Luna said Trixie and I are sisters. That can't be right, we never knew each other til she came to Ponyville with her magic show. I mean in, it could make sense in some way, but I don't remember any relation between the three of us. There has got to be an explanation to this. Like why Mama, shoot, no, Luna is calling us her "angels of the night" and why I called her "Mama" instead of Luna and also why I keep thinking of her as mama, and why we seem to be a family now,' Twilight told herself once more in thought.
Trixie had taken notice to the picture as well and was just as confused as Twilight. Then she and Twilight noticed something else. Both of them had wings like Luna in the picture. As Luna sat them up after she finished changing them, it was clear this was no joke. They now concluded as Luna set them on her back and wrapped her wings around them, like a bowl shape to keep them from falling, Luna was their mother, and they were both alicorn, and not just alicorn, but sisters.
"Alright, time to go and see your Aunt Celestia and your cousin Cadence my little ones," Luna said as she trotted out of the nursery.
The only thing that the girls thought through their head as the rode on Luna's back was, 'What have we gotten ourselves into?'
