A/N: Hello everyone. So I haven't posted in a while because of writer's block and school. Anyway I watched the Equestria Girls Movies last year and this year and I decided that a character should return to Equestria and her name is Sunset Shimmer. This character intrigued me and I wondered how would everypony react if she returned to Equestria especially Princess Celestia.

Enjoy ; )

"I'm so happy you could come for a visit Twilight," said Princess Cadance who was walking with her sister-in-law Twilight Sparkle. "It's a pleasure after all I need a break from Ponyville," replied Twilight. "Oh? Did something happen," asked Cadance. "No not really it's just I get a bit tired of Pinkie's parties every second day and Rainbow Dash trying to get me to go with her to a flying convention just so she can say that she's a friend of Princess Twilight Sparkle," replied Twilight.

Cadance smiled and said, "It sounds like it does get a bit tiresome." Twilight looked at her with a smile and giggled. They walked to the castle. Cadance led her to her room and said, "Shining Armor will be here soon to see you. In the meantime I'll be in my study." Twilight thanked her with a hug and began to unpack her saddlebags. Her door opened and she heard, "Twily!" She turned around and saw her brother Shining Armor who picked her up and spun her around in a hug. "Big Brother," she replied excitedly embracing the hug.

"Man it's great to see you again Twilight. I've missed you so much," said Shining Armor putting her on the ground again. Twilight smiled and said, "I've missed you too." "So how's everypony in Ponyville," asked Shining Armor. Twilight sighed and said, "They're okay but I'm worried if something happens while I'm gone." Shining placed a hoof on her shoulder and said, "From what I know about your friends they can definitely handle themselves." Twilight smiled again and said, "Oh I almost forgot." She levitated a comic book out of her saddlebag and said, "I bought this for you. It's the new superpony comic known as Wolf Pony." Shining Armor whinnied with joy and said, "You are the coolest little sister ever. Thanks a million." He hugged her again and she returned it.

After that Twilight continued to unpack her belongings and emerged from her room to see Flash Sentry. "Oh it's you," said Twilight blushing slightly. Flash chuckled a little and said, "Yup it's me." Twilight shook her head slightly and asked, "Is there something you need to tell me?" Flash looked up and said, "Oh yeah right. Umm...Princess Cadance wanted me to retrieve you for lunch." Twilight giggled and said, "Yes well thank you for coming to tell me." Flush smiled warmly and said, "Follow me Princess." "Please call me Twilight," replied Twilight.

Flash led her to the dining room where her seat was next to Cadance and across from her brother. She took her seat. Lunch today was a daisy sandwich accompanied with hay fries and a milkshake of choosing. They all began to eat and have a conversation. "At least it's peaceful here in The Crystal Empire," said Twilight. "Yes it is and actually very pleasant," replied Cadance. Shining floated a hay fry to Cadance and smiled. Cadance giggled and ate it out of his aura. Twilight sipped her milkshake.

After lunch all three went for a walk through the suburban area of The Crystal Empire. Twilight and Cadance were looking at dresses while Shining Armor looked at sports equipment. They returned to the castle an hour before dinner.

Meanwhile in a different world…

Sunset Shimmer was looking through her closet. "Dammit I swear it was here," she said moving out boxes. She was on her hands and knees and sneezed at the dust. "Crap this is ridiculous," she said. She stood up and hit her head on an overhead shelf. Then a box landed on her head. "Ow," she exclaimed. She rubbed her head and looked at the box. She opened it and saw a picture. She blew the dust off it and it was a picture of her and Princess Celestia.

She continued looking through the box and found a book. She opened it and saw that it was her old diary she used when she was in Equestria. She opend it and read a few pages. She opened on her last entry and read, "I've had enough of Celestia trying to teach me the magic of friendship. I want to rule not learn. I would be the perfect princess. I found a strange mirror and I believe it will lead to a new world where I can rule with an iron hoof. If Celestia finds this then I say you screw and I'm never coming back."

Sunset sighed and said, "I was so blinded by my arrogance." She felt a tear fall onto the page. She looked out her window and saw the school in the distance. The place she ruled by ways of fear and intimidation. Sunset sighed and said, "Princess Celestia would be embarrassed of me." She left the window and went to her mirror. She looked into it and saw a pony looking back at her. Deep down she knew who she was.

She began to feel more tears fall into the sink.

She heard a knock from downstairs. She wiped the tears away with the back of her hand and went downstairs and opened the door. It was Applejack, Fluttershy and Rarity with sleeping bags and their pyjamas with their duffle bags. "What are you girls doing here," Sunset asked. "We came over for a sleep over darling," replied Rarity. Sunset stepped aside to allow them entrance. All three girls entered. "I wasn't expecting a sleep over," said Sunset. "Tha's alright sugarcube it was ma idea," replied Applejack putting a hand on her shoulder.

Sunset changed into her pyjamas as Fluttershy packed out the games, Rarity packed out the snacks and drinks and Applejack set up the sleeping bags. They played the first few games and ate the snacks. They watched scary movies and had pillow fights. They played more games and danced to some music. Sunset enjoyed herself and so did the others. "So where's Rainbow Dash and Pinkie Pie," Sunset asked as they sat playing snakes and ladders. "Rainbow's currently out of town competing in a sporting event representing Canterlot High and Pinkie is visiting family," replied Applejack.

Sunset nodded as she moved her piece up a small ladder. "We had an idea to have a sleep over but we wanted to include you," said Fluttershy. "Yes darling we felt it wouldn't be right if we had one and you weren't included," said Rarity. Sunset smiled but quickly saddened. "What's wrong," asked Fluttershy. "It's just I miss my world. The one Twilight came from," replied Sunset.

"We understand. Yer feeling homesick," said Applejack as she placed a hand on Sunset's shoulder. "Yes we do because we have been away from our homes on a few occasions for extended times," said Rarity. Fluttershy knelt down next to Sunset and said, "We are here for you if you need us." Sunset hugged them all.

After a few more games and snacks they all turned in for the night. Sunset opened one eye and checked to see if the other three girls were sleeping. She got up quiet as a mouse and changed into her usual clothes. She thought about taking a small backpack which she quietly packed. She packed in her cloak, her picture of her and Celestia, her old diary, her favorite stuffed toy which is a phoenix and her favourite book.

She zipped the bag closed and quietly slipped downstairs and out of the front door. She caught a bus to the school and paid the fare. She walked to the statue and put her hand to the side of the pedastal that faced the front of the school and saw that the portal was open. She looked back at the school and looked at the portal. She breathed deeply and jumped into it.

Meanwhile in Equestria…

Twilight was in her room reading the latest Daring Do book. Suddenly the lights began to flicker. She looked around and heard no noise. She looked out of her room and felt something beckoning her to the room the mirror to the other world was in. She walked the corridors and saw the lights continued to flicker. She met Cadance at the door and asked, "What in Celestia's name is going on?" Cadance turned to her and said, "I have no idea but it seems something is happening in the room of the mirror."

They both entered and the door closed. Twilight looked at the mirror and saw it was glowing from the glass. She and Cadance moved closer and they saw some sparks wrap around the frame. Soon there was a tremor and Twilight moved closer. Suddenly there was a blinding light and both Alicorns shielded their eyes. After it dimmed slightly Twilight opened her eyes and saw a pony fly out the mirror.

The pony was light amber in colour, she had a red and yellow mane along with her tail. Her cutie mark was a red and yellow shimmering sun. She groaned and opened her eyes which were morderate cyan. "Sunset Shimmer," asked Twilight aghast. Sunset looked up and said, "Twilight Sparkle." "What are you doing here," they asked each other in unison.

"I'm here visiting my sister-in-law," replied Twilight gesturing to Cadance who was staring in question. "I've come back to Equestria," said Sunset Shimmer. Cadance walked over and asked, "Why is that?" Sunset saw she was a princess and bowed her head and said, "I wanted to come back because I miss Equestria and I want to make amends for what I did in the past." Twilight walked over to Sunset Shimmer and put a hoof on her shoulder, "I'm afraid it won't be that easy." Sunset looked up with a concerned look. "It's because you were gone for so long," said Twilight.

Sunset picked up her saddlebag and slung it over herself. "This is Cadance my sister-in-law," said Twilight gesturing to Cadance. "It is a pleasure to meet you Miss Shimmer," said Cadance smiling. Sunset smiled slightly and said, "Same." "She can stay in my room," said Twilight. "That's alright with me. I'll let your brother know that there wasn't anything to worry about," said Cadance smiling warmly. The three ponies made their way to Twilight's room. "Goodnight Twilight see you in the morning," said the older alicorn hugging Twilight who returned it. "So your sister-in-law is also a Princess what's next Celestia is your aunt in law?" said Sunset smirking.

Twilight chuckled nervously and said, "Yes actually." Sunset groaned and said, "Of course." Twilight frowned and said, "I see you haven't lost your sarcasm." "Hahaha never. I love it too much," said Sunset smirking. Twilight rolled her eyes and asked, "Why did you come back?" Sunset sighed and said, "I came back because I didn't belong in the other world. Not anymore at least. I mean AJ, Shy and Rare did come over to have a sleep over but it didn't feel right anymore. I miss Equestria and most importantly I miss Celestia." Twilight looked at Sunset Shimmer and hugged her.

Sunset returned the hug and nuzzled into Twilight's shoulder. Twilight blushed slightly and cleared her throat. Sunset broke the hug instantly and said, "Sorry Twilight. I don't know what came over me." Twilight smiled warmly and said, "It's okay." Twilight climbed back into bed and patted the spot next to her. Sunset smiled shyly and got into the bed next to Twilight. Twilight switched off her light and went to sleep. Sunset sighed. "Well I guess I'm home after so long. I hope Celestia can forgive me." She yawned and picked out the pheonix plushie and fell right to sleep.

Sunset awoke to the song of birds. She looked at her hooves and saw she was still a pony. She felt something soft around her and she saw that Twilight's wings had wrapped themselves around her. She smiled when she saw Twilight begin to stir and her eyes began to open. "Twilight Sparkle I had no idea you felt this way," said Sunset with a sly smile. Twilight looked at her wings and immediately blushed. Sunset chuckled and said, "You are adorable Princess, do you know that?" This caused Twilight to blush even more. Sunset began to laugh.

Twilight got up and said, "If you're down being a silly filly then get up. Breakfast is at 7." Sunset continued to chuckle as she got out of bed and picked up her saddlebag. Along with her diary and plushie she also brought her brush and toothbrush with toothpaste. She entered the en-suite bathroom and brushed her teeth at one sink while Twilight brushed out her mane. Sunset caught herself staring and the Alicorn several times. She finished her mane after brushing her teeth and smiled at her reflection. A pony looking back at a pony. "Come along Sunset it's time for breakfast," said Twilight. Sunset breathed deeply and followed Twilight to the dining room.

They entered the room and they found Cadance and Shining Armor already seated. Shining was drinking a cup of coffee while Cadance was drinking a glass of juice. Twilight and Sunset too the two opposite the couple. The server came over to them and asked what they would like to drink. "I'd like a mango smoothie," said Twilight. "I would like the same please," said Sunset. The server smiled and left to the kitchen. "So who's your friend," asked Shining smiling at Sunset. "This is Sunset Shimmer. She's from the otherside of the crystal mirror. Well she was originally from here then she left," said Twilight. Shining smiled and said, "I'm Shining Armor, it's a pleasure to meet you." Sunset smiled and said, "Charmed."

The server returned with the smoothies and the other servers arrived with eggs and toast. They all enjoyed the breakfast. Twilight and Sunset returned to their room and Twilight took out a piece of parchment, a quill and ink pot. Sunset looked at her and asked, "What are you doing?" Twilight walked over to the desk and said, "I'm writing a letter to Princess Celestia to tell her that you've come home." Sunset bit her lip and said, "I'm afraid." Twilight looked at her with a questioned look and asked, "Celestia?"

Sunset nodded and said, "Yeah. I'm afraid that she doesn't forgive me for what I did before I left to the other world." Twilight walked over and put a hoof on Sunset's shoulder and said, "Celestia is forgiving and understanding. You were her prized pupil. If she knew you returned she would want to see you immediately." Sunset looked at Twilight and said, "I do want to see her but I want to surprise her. I want to see how she will react if she didn't know I returned." Twilight smiled and said, "How about this? I'll organise a visit with Celestia and then you can see her." Sunset smiled and asked, "You'd do that for me?" Twilight nodded and began writing.

Twilight finished the letter and said, "When we get back to Ponyville I'll have Spike send it to her." Sunset hugged Twilight. Twilight smiled and returned the hug. "Ahem," said a voice. They looked to see Flash Sentry looking at them both. "Flash," Sunset asked surprised. "Sunset," he replied just as shocked. Twilight looked at them and asked, "You know each other?" Sunset swallowed hard and said, "We did." Flash narrowed his gaze and said, "A long time ago." Twilight felt tension building and turned to Flash. "Is there something you need to tell us?" She asked. Flash shook his head and said, "I came to tell you that Princess Cadance and Shining Armor will be attending to royal duties today."

Twilight nodded and said, "Tell them Sunset and I will be leaving after dinner for Ponyville." Flash nodded and whispered to Twilight, "Don't trust her Twilight. She'll stab you in the back at the first sight of trouble." He turned and left the room. Twilight looked at Sunset and asked, "What happened between you two?" Sunset sighed and said, "I left him at the altar on our wedding day." Twilight's eyes widened. "It was the day before I left for the other world. I couldn't be with him especially with my ambition," said Sunset. Twilight walked over and hugged Sunset.

The day was relatively short for both of them because they were busy shopping and having a great time. They returned to the castle an hour before dinner to pack their belongings for the train ride to Ponyville. Sunset packed in her phoenix and Twilight giggled. "Is that your plushie," she asked. Sunset blushed and said, "Yeah I picked her up when I first arrived there. It reminded me of Philomena." Twilight smiled and said, "I have Smarty Pants. She's been my best friend for a very long time."

They entered the dinning room and Twilight told Cadance and Shining about tonight. "It was the best weekend ever. We're sorry we couldn't spend more time with you Twilight," said Cadance. Twilight smiled and said, "It's alright. If I didn't come I would have never seen Sunset again or take her with me to Ponyville." The four ate dinner and after they were finished Twilight and Sunset went to the room to get their saddlebags. They both walked to the front door and saw Cadance and Shining Armor waiting for them. Twilight hugged her brother and did her greeting with Cadance, "Sunshine Sunshine, Ladybugs awake, clop your hooves and give a little shake." Sunset smiled at them. Sunset thanked both of the older ponies for allowing her to stay for the time and for their hospitality.

Sunset and Twilight left the castle and travelled to the train station. They boarded the train and it departed for Ponyville. Twilight and Sunset entered their coach they'd be staying in and got into their bunks. Sunset sighed and asked, "Twilight are your friends like mine from Canterlot High?" Twilight looked up from her book and said, "You have no idea how similar they are."

Sunset smiled and said, "I hope they accept me like you did." Twilight looked at her and said, "I know they will." Sunset closed her eyes and fell asleep. She dreamed of Twilight and her on the beach having fun and swimming in the sea. She dreamed of her and Twilight relaxing on the beach and enjoying each others company. Sunset woke up from her dreams and saw it was still night. She figured that it might be 3am. She looked over to Twilight's bunk and saw her sound asleep. Sunset got up and walked to the back coach. She opened the door to the small balcony of the rear coach and watched the countryside fly past.

The wind in her mane was like no other. She looked up to the night sky and saw the moon half way full. She breathed in the air and sighed with content. "I'm home." She thought to herself. She went back to her coach and still found Twilight asleep. Sunset smiled and stroked Twilight's cheek softly. The Alicorn sighed happily and snuggled into her pillow. Sunset sighed and climbed into her bunk again and went back to sleep.

She awoke again to see Twilight stretching her wings and brushing out her mane. "Morning Sunset," she said. "Morning," replied Sunset. She got out of her bunk and stretched her legs. They heard the conductor over the intercom, "Next stop Ponyville. We will be arriving in 30min." Sunset smirked at Twilight and said, "We have 30 minutes to do whatever we want." Twilight blushed and said, "Sunset that seems a bit risque even for you." Sunset smirked again, "Oh come on Princess let's have some fun." Twilight blushed even harder. Sunset burst into laughter and said, "You are too easy Twilight Sparkle." Twilight continued to blush until she also started to chuckle.

The train pulled into the station and the two ponies disembarked. Twilight met her friends waiting for her and they all participated in a group hug. "Girls I'd like you to meet somepony," said Twilight after the hug. She turned to Sunset and said, "This is Sunset Shimmer. The mare I told you about from the other world." Sunset smiled and walked over. "You don't need to introduce yourselves. I know all of your names," she said. Pinkie bounced over and said, "If you do know us then who am I?" Sunset smiled and said, "Pinkie Pie, you live at Sugarcube Corner and you're the biggest party pony in Equestria." Pinkie leaned over to Twilight and said, "Oh she's good."

They all laughed and walked to the Castle of Friendship. "So yall left before Twi became her student," asked Applejack walking with Sunset Shimmer. "Yes. I was her pupil before Twilight and I'm sure she values Twilight above me at this stage," replied Sunset. "Well darling if I know Celestia, which I slightly do, I'm sure she would be thrilled to have you back in Equestria," said Rarity. "Yeah if you were Celestia's prized pupil before Twilight then she would be stoked to have you back," said Rainbow Dash flying overhead. Sunset looked at Applejack, "You really think that she'd forgive me?" "Sugarcube she wouldn' be Celestia if she didn'," said Applejack with a reassuring smile.

They arrived at the Castle and Twilight called, "Spike I'm home." Owlowiscious flew over and nuzzled Twilight who giggled and said, "It's great to see you too Owlowiscious." The owl flew back to its perch and sat. Spike came in and said, "Welcome back Twilight. Did you enjoy your trip?" "I sure did Spike," said Twilight rubbing his head with her hoof. "I've got a letter here for Princess Celestia," she said levitating the scrool out of her saddlebag. "Yes ma'am," said Spike.

He took the scroll and breathed his green flame onto the scroll nad it turned into a purple mist and flew out of the open window. Spike then saw Sunset Shimmer, "Sunset Shimmer?" Sunset smiled and said, "Hey Spike." "What are you doing here," he asked. "She's come back to Equestria," said Twilight. "That's awesome, but what about your friends at Canterlot High," he asked. Sunset looked away and said, "They were fine without me so they'll be fine without me now." "You ran away," asked Fluttershy. Sunset turned to the group and said, "Yes. I don't belong there anymore. I'm a pony at heart and this is my home." The six friends walked over and hugged her.

At that moment Spike burped. "Lovely Spike surely you could've excused yourself before releasing a belch," said Rarity in slight annoyance. "Sorry but Celestia replied," he said blushing. "What does it say," asked Sunset Shimmer. Spike unrolled the letter and read, "My dearest Twilight Sparkle I look forwrd to your visit to Canterlot. I believe Wednesday will be the best day for you to visit. Feel free to bring your friends if you wish. I look forward to seeing you again. Yours Faitfully Princess Celestia." Sunset nodded and said, "Wednesday it shall be Celestia."
