Twilit Butterfly

Spike was asleep, dreaming about his princess, when Twilight came home, slamming everything around. She was about to slam him with a book, but stopped and tapped him lightly.
"Hizza, wha? Twilight, why did you wake me up? I was having the best dream ever!
Twilight couldn't look more agitated if she tried. Spike sat straight up when he realized something was wrong,
"Hey, what's wrong? Did one of your friends ditch you?"
Twilight scoffed, "One of them? Ditched? I wish. Almost all of them are against me! And the one who isn't probably thinks I hate her right now!"
Twilight let out a huge sigh as she climbed into bed, "This has been the worst day ever."
Spike climbed up next to her and stroked her mane, "Please, tell me what happened."
Twilight gave him a weak look before retelling the events of her day.

"Twilight!"
The unicorn turned around to see a familiar canary yellow Pegasus behind her. "Oh, hey Fluttershy! How are you?"
Fluttershy trotted up and started pawing at the ground. "Well, I have something to tell you." Twilight was worried about what it might be.
"I love you."
The violet mare suddenly felt like a shrinking violet. Of all the things that could have been said, she didn't expect that. Even more so, she didn't like mares like that. It was like her mind shut down on her. "I... I... no. I'm sorry. I don't go that way. I... just... I'm sorry."
Fluttershy stood there for a second, then hung her head, "Okay..." She had a tear in her eye as she turned to leave.
Twilight watched her saddened friend walk away, wondering if there was a way to soften the blow any more than she did. She turned to continue back to the library when she noticed Rarity approaching her.
"Twilight? was she crying?" Rarity asked in a concerned tone. "What was she sad about?" All of a sudden, she turned aggressive. "Did you say something mean to her?"
Before Twilight could think of a response, Rainbow Dash swooped down from the clouds. "What did you do? WHAT DID YOU DO? Fluttershy was being nice, and all of a sudden, you broke her heart!"
"What in tarnation's going on here?" Twilight turned to see both of the earth ponies of the group approaching.
Twilight hoped one of them could give her some salvation.
Sadly, fate was not so kind.
"She made Fluttershy cry!" AJ's jaw dropped, while Pinkie's eyes went wide.
"WHAT!?”
"Why the hay would you do that, Twilight? Ah thought we were friends."
"Yeah, well-" Rainbow went for another blow.
"Well friends don't make friends cry, Twilight!"
"But I-" Pinkie decided to get on the blame train.
"Twilight, you are the worst friend ever! Just go away, Miss Meany-McMeanypants!"

"And then I just ran straight here."
Spike was holding her for the last part, which was obviously harder for her to tell. He would have made a joke about her saying straight, but it would have probably hurt her that he wasn't taking things seriously.
"It's like the whole lesson thing all over again, except it's the whole situation they're misjudging, and not just your reaction to it."
Twilight gave him a weak smile, before nuzzling up closer to him, "I knew there was a reason I went to you." He rested his head on hers.
At that moment, the door to the room swung open, and in walked Rarity. "Twilight, I know there was something else going on that I wasn't informed of, but the girls wouldn't let you speak. So could you please tell me why Fluttershy was crying?"
Twilight was about to talk when Spike, somehow resisting Rarity's charm, put his hand under her muzzle as a polite way of quieting her. He let out a sigh before starting, "Fluttershy said that she loved Twilight. Twilight, on the other hand..." He looked back at Twilight to make sure she was still okay.
"...Oh. I get it." Rarity was wise in the art of romance. "It was a rejection. That always breaks even the toughest of hearts."
"What does?"
As if she tried to have bad timing, Rainbow flew in through the window. "Being told you're useless? Yeah, I talked to her!"
Obviously not, because Twilight never said anything like that to Fluttershy.
Rarity called her out on it. "Rainbow! How dare you be so cruel and insensitive?" In her own way. Applejack coming in didn't help either.
Rainbow rolled her eyes, "Well, I'm not the sensitive Pegasus that needs somepony to stand up for her! Why are you protecting the jerk anyway?"
Spike ran between them. "Girls, stop. There has to be a way to-"
"WAGH!" *CRASH*
Spike spun around in time to see Applejack approaching Twilight, who was against the wall and on the ground, with startling speed.
"APPLEJACK, WAIT!"
Applejack was mid buck when the shout rang out. After hearing a crunch that she usually heard from a colt that had one too many drinks, she started to walk away proudly.
"Ow..."
Upon hearing a voice too soft to be Twilight's, she spun around to see Fluttershy sitting between them, holding her chest in pain.
AJ looked panicked, "Fluttershy? What in tarnation are you doing?"
Fluttershy shot her an uncharacteristically aggressive glare. "I told her I loved her, she told me that she doesn't love me like that. That's all that happened." Fluttershy finally softened her expression. "We're still friends, there was just a slight problem. That's all. Please don't be mad at her."
Applejack was awestruck. "Well, shoot, I thought Twi went and flat out insulted you. I'm sorry, Twilight. Can you forgive me?"
"More like, can you forgive us? I was the reason Pinkie and AJ got the wrong idea."
Twilight gave Rainbow a weak smile. "Yeah, I forgive you. And, Fluttershy? I'm sorry. I tried to be as soft as possible, but I still made you cry. Is there anything I can do to make up for hurting your feelings?"
Fluttershy gave a soft smile. "No, it's okay. I always knew there was a chance of you rejecting me. Let's just try our best to move past this, okay?"
Twilight nodded enthusiastically.
Fluttershy moved to stand, only to wince and squeak before falling on her side.
Applejack sighed guiltily, and glanced off to the side, "Two days an' five hours, at least. An' that's judging from ponies much tougher than you. I'm sorry, Fluttershy."
Fluttershy somehow kept her smile. "It's okay Applejack."
She was suddenly encased in a purple glow and lifted towards the bed. "Don’t worry, Fluttershy." Twilight reassured her. "I'll take care of you."
"Thanks, Twilight."
"Anything for a friend."

Five days later, Fluttershy was completely healed and back to normal. As they agreed, Twilight and Fluttershy went back to being close friends afterwards, perhaps even closer than before.
After accompanying Rarity on a trip to Canterlot, Twilight started receiving letters from an unknown source, though she still trusted them and seemed excited to get each letter when they came.
Fluttershy, meanwhile, started a relationship with a young mare from Cloudsdale. Though none of her earth bound friends met her, Rainbow says that the mare is,
"...as sweet as Fluttershy, as protective as I am, and as prissy as Rarity."
"Hey!"
"Well it's true!"
When asked about their love lives, Applejack and Rainbow just say, "Its fine." Pinkie, however, says she can't settle with anyone, and for some reason very insistent on anyone, not anypony, making Twilight think she tried with more than just ponies.
Rarity just claims jealousy towards Fluttershy and, for reasons Rainbow couldn't figure out, Twilight. Though one of them was insistent on ignoring a strange mark on their neck...
