Starlight walked through the streets of the Crystal Empire. It seemed like everything was alright. Something seemed wrong though. Starlight tried to ignore it. She trotted towards Sunburst's house. Although nopony knew it, she had a crush on him. Ever since he left for magic school, she had only thought of him. She stepped in front of his house. She took a deep breath. She had a feeling something terrible was about to happen. Something really, really terrible. She couldn't just brush it off. It wasn't even something she was consciously aware of. She didn't know what was wrong or why she just knew. She turned away from the door. Sunburst could wait. She needed to know. Starlight stopped. It was probably nothing. She knocked on her friend's door. She waited a minute. Sunburst wasn't exactly an organized pony and he was probably stepping over piles of books and scrolls trying to get to his door. When the door finally opened, a wild-maned Sunburst came out. Starlight smiled. "Hey Sunburst," she couldn't think of anything else to say. "What happened to you?"

"Let's just say there was an incident."

"So, what's new?"

"I have a girlfriend now. Her name's Moondancer. She's from Canterlot."

"Oh, anything else?"

"Not really. What about you?"

"Me? Well, um, nothing really. Listen, I gotta go somewhere. Bye." She turned away from his door and walked away sadly. She still had that uneasy feeling. She figured it was just her sadness. That sadness, however, was soon replaced by anger. Turned around to face the open door.

"Starlight, are you okay?"

"No, I'm not okay! How could you be so oblivious!"

"Starlight I don't know what you're talking about."

"I loved you! How could you not notice?!"

"You never told me!"

"How did you not see the signs? I followed you around everywhere when we were kids, and literally started a cult because you left me!"

"Look I'm sorry! I just thought we would be friends! I never had any romantic feelings for you!"

"Well sometimes, if somepony likes you, you should try to like them back!"

"I wasn't just gonna wait until you tell me you like me to get a marefriend!"

"Why did you never ask me!" There were tears in Starlight's eyes now.

"Because I didn't like you in that way!"

"You could have at least asked me so that I could tell you!"

"Well sorry for not knowing!"

"You know what? I don't think I could ever be friends with somepony that oblivious and selfish!"

"Oh, I'm selfish? You literally wanted me to never have a marefriend until you confessed your love to me!"

"Well, it doesn't matter anymore! I don't even care about you anymore! Go run off with your marefriend somewhere! See if I care!"

"Maybe I will then!" Starlight turned around. She looked back one more time.

"You know, I don't see why ever liked you in the first place." She walked away. She wandered into a dark alley nearby. Her eyes glowed a menacing red with green sclera, as well as purple mist emitting from them.

Meanwhile, Twilight was still in the library. She stomped her hoof on the ashes on the tapestry. Celestia would fall someday. And Twilight would make sure that was soon. Her appearance turned normal but hatred still burned in her soul. She stormed out the door, the book tucked under her wing. It became locked again. She went back into the hidden room. Somehow, nopony noticed it. Her horn ignited, she green and purple orbs went into the lock. The book opened, but only with dark magic. She went back out. She stepped into a dark alleyway. She found Starlight there. "Starlight? What are you doing here?"

"Let's just say I had a bad day."

"Want to talk about it?" Twilight said. She couldn’t take her anger out on her. Not now.

"Sunburst got a girlfriend." Twilight didn't even have to ask why this made Starlight upset. "I also had an uneasy feeling before and after I talked to him." Twilight realized something. Those feelings were from her uses of dark magic as well as feelings of darkness in Starlight. She decided not to bring up her discovery. Not yet. "Why are you here?"

"I was just walking around the city. I gotta do something before we leave. Why don't you go do some sightseeing?"

"I guess it'll take my mind off of today."

"I think you need that." Twilight did her best to smile. As soon as Starlight walked away, however, Twilight felt rage burning in her soul. She walked up to a store and got a quill and some parchment. She wrote a note on it. It read:

Dear Shining Armor,

I can't believe you would do this to me. I found out the truth about myself and all I can feel is anger. You lied to me for my entire life and didn't even care! I don't think I will ever forgive you for this. Don't expect a visit anytime soon. Or ever for that matter. I'm going to be with Starlight the rest of the day. As far as I'm concerned, she's the only family I have left.

Your former sister,

Twilight Sparkle

Twilight put it in an envelope, took it to the Crystal Castle, then told a guard to give it to Shining Armor. She looked at the castle with a look of pure hatred. It would have looked better with black crystals and sharper edges. She had an idea. She would use it soon. But not yet. First, she had to tell her.

Shining Armor read the note for the third time in a row. His sister found out about her destiny and hated him. He couldn't talk to her. Not while she was this angry. He would destroy Sombra once and for all if he even tried to do anything to Twilight. Right now, he needed somepony else to talk to her. Somepony she trusted.

Author's Notes:

This was the only way I could incorporate Moonburst and Starburst in the same fic. I drew upon all my anger for this chapter and typed as fast as possible. And I got the "As far as I'm concerned she's the only family I have left." line from Stan Pines.
