On a sunny morning, during break time, the Equestria girls were spending their time near a horse statue or perhaps commonly known as a portal to another dimension (Equestria)
Something unexpected happened. There is someone who comes out of the portal. The girls were shocked, especially Rainbow Dash, who got ready to fight "Who is that? Oh yeah!"
Applejack held back "Hold on Dash, what if it was Twilight?"
Twilight blinked and looked at Applejack "Me?"
"Oh yes, I mean the other me" Twilight said nervously
Sunset was surprised "But what made Twilight come here–"
Yep, what came out of the portal was not Twilight, but a man with amber-skin, orange-hair, and cyan-eyes. "Whoa!" Said the man fell from the portal.
Then Twilight came out after him "Oh my gosh! Let's just go home and forget about it!"
The Equestria girl was shocked "Twilight?!"
Twilight was surprised to hear them shout at her "Uh.. Hi.. Guys, long time no see" She said trying to cover her panicked voice towards her friend.
Sunset was surprised to see the man "Sunburst?"
The man looked at Sunset "Sunset! I'm happy to meet you again!"
The Equestria girls were surprised, "Wait.. You know him Sunset?" Applejack asked.
"Um.. Yeah.. I–" Her words were cut off by Sunburst.
"Sunset! I mean Sis. Let's go home, mom and dad are waiting for you," said Sunburst
The Equestria girls were silent for a moment and were shocked "What?! Sis?! You mean he's your brother?!"
Sunset just widened her smile, then turned her gaze to Sunburst "What are you doing?"
"Asking you to come home" Sunburst replied.
Sunset was shocked and tried to change the topic "No no, I mean, what are you doing on the ground?" She said while holding back laughter.
Sunburst looked at himself and felt embarrassed by his behavior and tried to stand on his 'two feet'. Twilight wondered why she wasn't at all surprised by this 'dimension'. "Wow, I'm surprised there are ponies who aren't surprised by their 'new form'"
"Hah?" Sunburst said in a confused tone then looked at his hand "Aaaaaaaa! What is this?!" He is screaming.
"That's a hand, and you're standing on 'two legs'" Sunset answered.
"Aaaaaaaa! This is crazy! Come on Sun– I mean... Sis! We better go home!" Sunburst said in panic.
Sunset was silent for a moment and rejected Sunburst's invitation "I don't think... No."
"Sis?" Sunburst grabbed Sunset's hand.
Sunset forcefully let go when Sunburst grabbed her hand "I said no! After what you did before, now you want me to go home?"
"S-sunset? I–" Just as Twilight was about to speak, Sunburst cut her off.
"Please sis, we promise we won't do it again...!" Sunburst forced.
"I. Already. Said. I don't want to! What makes me so special now?! You guys never even considered me part of you. I hate you!" Sunset said, she covered her mouth, she didn't mean to say that to her brother. "Leave me alone" Sunset turned around "I've found a place I can call 'Home'"
"W-we're sorry, we know we were wrong.. So–" Sunburst was cut off by Sunset.
"I said no! How many times do I have to say it?! You guys made me feel uncomfortable with you and then you want me to come back with you?! Are you lost your mind?!" Sunset said. Sunset sighed "It's just... Leave me alone. I still need to digest my brain to return to my real 'home'."
"B-but sis–.."
"I said leave me alone!" Sunset ran to avoid Sunburst and her friends.
"Sunset!" The Equestria girl called her name in worry. Including Princess Twilight.
"What makes her didn't want to go home, I mean... Isn't that strange?" Twilight asked her friend.
"You know Sci-Twi? I don't know either, I've never seen her like that before" Pinkie answered.
Twilight blinked "Sci-Twi?"
"Probably to avoid misunderstandings between the two of us" Twilight answered.
"Oh... I think you're right"
"But the most important thing here is, we should ask 'him', I think he knows something" Said Applejack while looking at Sunburst.
The Equestria Girls saw it and asked "So, why would Sunset say something like that? You must know something" Asked Rainbow Dash.
Sunburst looked at Rainbow Dash and tried to avoid Rainbow's question "Aa– nothing! It's just.. We.. Were fighting! Very childish isn't it–?"
Applejack felt unsure about Sunburst's statement "Tell me the truth, we know you're hiding something. Especially when Sunset said 'What makes you think She is special now', so... Do you have a real statement?"
Sunburst couldn't avoid this question. Sunburst sighed then answered Applejack's question "Huh.. Yes.. That's because..." Silenced for a moment, the Equestria girl looked at him with a serious look, as did Twilight who didn't know anything about her family. Sunburst continued his words, "That's because.. We never cared about her.. Even I.. To the point of slandering him so that she wouldn't get attention from mom and dad.." He answered in a sad tone.
"What?!" Equestria Girl and Twilight were very surprised to hear Sunburst's statement.
"How could you do such a cruel thing?!" Rarity asked.
"That's so cruel.." Fluttershy added.
Sunburst sighed "I know it's crazy.. Not crazy but cruel.. I know that my behavior was wrong.. But I have realized that what I did was too much, I just want to apologize to her and ask my sister to come home." Sunburst answered very sadly, realizing his old mistake towards Sunset.
Applejack sighed "Sweet apple sour, that's more than cruel. Okay listen to me Sugarcube, ah think for now we'd better not force Sunset to go home to Equestria, it will only make her more depressed. Ya should find another way to apologize to her" Applejack said with Sympathy.
"Okay.. Sorry.." Sunburst apologized.
"Oh, hup, ches. Darling, you don't have to apologize to us, you should apologize to Sunset," Said Rarity while holding Sunburst's shoulder.
The other girls nodded in agreement.
"I think I should go back to Equestria, because.. Well.. You know?" Twilight coded.
"We understand Twilight" Rainbow smile understanding.
"Do you mind if I stay here..? I still want to apologize to Sunset.." Sunburst asked.
"I guess... But where will you live then?" Twilight asked.
"Calm down Twily! I'll rent him an apartment!" Pinkie suggested.
"Are you sure that's okay with you?" Sunburst asked.
"No, absolutely not!" Pinkie took Cupcake out of her Hair as usual.
Sunburst blinked his eye.
"Pinkie still Pinkie" Said Twilight– I mean Sci-Twi.
"Alright.. It's time for me to go" Said Twilight.
The girls hugged Twilight "Awww we're going to miss you so much"
"Me too" Twilight looked towards the Statue– Portal. "Goodbye everyone, please look after Sunburst for me.. And.. Sunset" Twilight entered the portal to return.
"Bye Twilight! Of course we will!" Pinkie said.
