At the Crystal Empire Princess Cadence had invited her Aunt Celestia and Luna to tea, its been a while sense they all sat down together since she became the ruler of the Empire and she misses them sometimes, they were sitting in her and Shining Armor's room enjoying a long deserved chat with her Aunts.
"And that's my dear niece is why you can never have too much cake." Celestia said.
Cadence nodded, "Okay, so what do you do when that cake...goes straight to your thighs?" she asked.
Celestia giggled, "There are advantages to being a princess Cadence." she said then took a sip of her tea.
Luna rolled her eyes, "Thy think moon pie is a more delicious desert treat then cake." she retorted not agreeing with her sister's statement, Celestia looked at Luna.
"Everypony has there own opinion Luna." she replied.
Cadence nodded in agreement and looked away for a minute then she saw something strange, "What the hay?"
Celestia looked at her niece, "What is it Cadence?" she asked then she and Luna looked in the same direction as Cadence and they saw what she was looking at.
On the other side of the room The Crystal mirror that lead to another world was starting to ripple indicating that somepony was coming through Cadence had for some reason decided to put the mirror back in her room even though her Aunt's thought it was a bad idea she did it anyway.
Celestia gasped, "Somepony's coming through!"
Luna raised a brow, "But the thirty day moon cycle isn't even up yet, it's only been Fifteen?" Luna retorted remembering that its only been that long since Twilight came back from that world with her crown.
Cadence put a hoof to her chin questionably, "But who's coming through?"
The mirror bursted into glowing light and all the princesses covered their eyes from the light when the glow disappeared Celestia uncovered her eyes and looked at the mirror and was shocked to see what was there, in front of the mirror was... a foal with a red and yellow mane and coat laying on the floor Celestia came up to the foal and poked her.
The foal started to stir and opened her eyes then looked up at Celestia and smiled, "Cewestia!" the foal said happily.
Celestia stood back surprised at the foals ability to speak but then bent down to get closer at the young one, "And who are you little one?" Celestia asked.
The filly tilted her head, "Cewestia its me, Sunset shimmew," she said then she noticed her voice sounded different and clutched her throat, "What wong with my voice!?"
Celestia raised a brow, "Sunset is it really you?" she asked the foal let go of her neck and looked up at her and nodded.
"Yes, I came back, what's wong with my voice though? It sounds so high and squeaky," then she noticed that everything looked bigger then it should be, "and why does everyting wook so big?" she asked.
Celestia was shocked this was indeed Sunset she then bent down closer to the foal for composure, "Umm I don't know how to explain this to you but...you're a baby." she replied nervously.
"What!?" Sunset yelled then looked behind her at the mirror and saw a foal in the reflection with the exact same mane and coat as she does and moved the same way she did, she looked at her reflection for a long time then her eyes started to water and she cried.
Celestia being the kind nurturing pony she is scooped up the foal and started rocking her to try and stop her crying, Luna and Cadence had stood behind and watched the whole scene to shocked to move then when Sunset started crying they both got close to Celestia and cooed to the foal trying to help her stop crying.
When Sunset's crying finally stopped she looked up at Celestia, "How did this happened to me?" she sniffled.
Celestia looked at the mirror, "Maybe this is another power of the Crystal mirror," she said then looked back down at Sunset, "other than that, why have you returned my old student?" Celestia asked.
Sunset rubbed her eyes, "Since Twiwght defeated me I've been thinking about what I've done and I decided to make amends," she explained looking up at the big pony's, "so I started going around in the other world gaining evewybody's forgiveness and saying I'm sowwy." she replied.
Celestia smiled, "Well I'm glad you learned your lesson but how did you manage to get back the portal to that world should still be closed?" she asked.
Sunset shrugged, "I don't know I wanted to come back her and apologize and..." she paused to take a deep breath, "...say sowwy to you to Cewestia for my arrogance I was wong and...hoping you would take me back as your student and teach me about fwiendship like Twilight spawkle." she said with big puppy eyes.
"All is forgiven Sunset." Celestia said nuzzling the foals mane.
"I saw that the portal was opened earwier than it should be and took the chance to come back and well I guess this happened." Sunset said ending her story.
"Well it's good that you aren't hurt and that you have come for forgiveness but what now? She's way to young to be your student sister and now we have a foal on our hooves and we can't keep her a foal at the castle?" Princess Luna asked.
"You're right sister," Celestia said then put a hoof to her chin, "hmm, if you truly wish to learn about the magic of friendship and this is one of those problems we don't want to deal with there's only one pony for the job."
At Twilight Sparkle's home Twilight just put Trixie to bed for the night and was about to go to sleep herself until there was a knock at her front door.
"Now who could that be?" Twilight asked herself then she went downstairs to her door and opened it revealing Princess Celestia, "Celestia! what are you doing here!?" she asked her monarch.
Celestia smiled, "I have a request of you my faithful student." she said then she levitated a cover basket in front of her, Twilight raised a brow at her request and what could possibly be in the basket.
"What do you need me to do?" she asked.
Celestia then removed the blanket revealing Sunset in the basket sleeping peacefully in it from traveling so far with Celestia Twilight d'awwed, "I need you to take care of Sunset Shimmer." she said.
Twilight looked away from the foal at her teacher her eyes growing wide, "Sunset Shimmer!?" Celestia then explained what happened and that Sunset would like to learn the magic of Friendship and that she would be the best for the job.
"So please my faithful student could you please teach Sunset the magic of friendship?" Celestia pleaded.
Twilight looked at Sunset then at Celestia and smiled, "It would be my honor Celestia, Sunset could learn along with Trixie in friendship." she said happily.
The Princess smiled, "Good to hear, you know if you don't mind I would like to meet Trixie?" she asked never before meeting Trixie except in friendship reports from Twilight.
"Okay lets go then see her then." Twilight said then leading Celestia upstairs carrying Sunset in the basket she took her to her room and to Trixie's crib where the little show mare was sleeping.
Celestia looked down at the filly and d'aww, "D'aww she is cute, I hope these two will get along."
"Oh I think they'll get along." Twilight retorted.
Celestia looked at her student questionably, "What makes you say that?"
"They both have something in common," Twilight giggled, "There both good in magic and they both been beaten by me."
Celestia giggled, "Alright if you say so, I will be leaving Sunset in your hooves," then levitating Sunset out of the basket carful not to wake her she lower her into the crib with Trixie and tucked her in with the blanket she had brought for her a red blanket with her cutie mark on it, "well I guess my work here is done so I should be leaving now." she said going back downstairs.
Twilight followed her downstairs and smiled, "Don't worry I'll take good care of Sunset and you can come see her anytime you want." she said happily to sure her master she can handle it.
Celestia smiled, "I know you will be good to Sunset, farewell my faithful student." she said then walked out the door and closed it behind her magically locking it for Twilight.
Twilight sighed, "Well it looks like I have another little one in my hooves," she giggled and smiled, "I wonder how Trixie will handle a new playmate."
