BTW I made some changes to the previous chapter so if this chapter doesn't make a lot of sense at some parts, just review the previous chapter.

Rainbow flew as fast as she could. Something had come over her the past days, she wasn't herself and seemed to be blaming Discord for everything and anything. She even left Fluttershy hurt and sobbing on the floor of her cottage. She did care for Fluttershy, she was one of her best friends, but she seemed to care more about revealing Discord's, supposed, true evil nature.

Canterlot was getting close, she sped up.
Discord was in a meeting with Celestia, Luna and some other important rulers across Equestria. When Rainbow arrived she realized she couldn't just intrude on an important meeting, not to mention perhaps embarrass herself in front of Royalty. She would wait for them to take a break.

(45 min later): she actually waited that long.

Discord stepped out of the conference room towards the Canterlot Gardens, that was what he was planning anyway. He was halted by a raging and accusing pegasus.

"You!" she pointed her hoof.

"Rainbow? What are you doing here, shouldn't you be boasting right now?" he commented as he looked at is wrist, imagining a watch.

"You think you're so funny, you think you have every pony fooled, well not me Discord. I saw you two in the bedroom, you hurt her while putting an enchantment on her in the process so we can't touch her! An-"

"Wait, what?" his eyes widened in curiosity and a bit of fear.

"That stupid necklace you put on her. Every time someone tries to remove it or touch it, something bad happens. You want her to fear every pony and find comfort in your evil lies. You-"

"How do you know about the necklace, more importantly how it works!?" he was worried now, he didn't even bother explaining how he didn't put it there.

"I tried to take it off but she wouldn't let me and now here I am," she left out the rest of the story.

"What did you do?" Discord raised his tone.

"Nothing, she's probably fine by now anyway. Now come clean, did you or didn't you cast a spell on her?!"
Discord's eyes burned and glowed.

"I would never hurt her, I would never put her under a spell and I would never turn her against you again!" he glared.

"LIAR!" she shot back.

"I am telling nothing but the truth, ask Applejack."

"Lies, they're all lies!"

"Why are you so convinced they are?!"

"Because that's the only way she could ever even like you!," she said, "This has to be the only way she can care for you, she is the Element of Kindness and you are the Lord of Chaos. Fluttershy has never been in love, never kept secrets and barely had romantic feelings for any pony. So you casting a spell on her is the only valid explanation for her returning your care," she poured out.

Discord was speechless.

"What you want to think is ok as long as you don't show it aloud, but it seems you care more about being right than your friend's happiness cause I assure you that hurting that pony is the last thing I would ever want to do." He took a deep breath remembering the start of their conversation. In a panic he disappeared.
Rainbow stood there with her thoughts, she considered the fact he could be telling the truth and if that were the case, that she was a jerk.

In her confusion she just flew back to Ponyville.

Discord appeared in Fluttershy's cottage but couldn't see her anywhere, which was strange because his magic was supposed to take him right to her.

"Fluttershy!" he heard no reply. His heart was in his throat and he felt a shiver go up his spine and then something else. He felt something that he had felt a few times and new well, evil. He could sense a terrible presence which only made his situation worse.

He then look to a small corner where the yellow pegasus lay on her side where her back faced him, she looked dead cold and faint. Over top of her was a dark shadow that seemed to be sucking the life out of her, every time the shadow moved it seemed to take a bit of her with it.
Discord ran to her side and tried to touch her but the shadow was like a rubber forcefield that left her inside a giant bubble. Discod began pounding on it.

"Fluttershy!" her eyes slowly flittered but it wasn't enough. Discord stopped hitting the forcefield and instead calmly placed his claw and paw atop it.

"Fluttershy, if you can hear me in any way I need you to fight this. You need to use your goodness, kindness, hopeful and loving nature. I need you to hear this, I'm sorry I left you. You mean the world to me in every way and I can't lose you. Please, feel how I feel about you and take my paw," he slowly pressed deeper, the black shadow turned gold and wasn't resisting his touch. As he got further, he could finally touch her and feel her soft fur. Soon the 'bubble' popped.

He carefully turned her over to see she was bruised, scratched and had a small amount of blood on her, her wing also looked a bit twisted. Her cheeks were red from what he assumed was crying, which appeared she had done a lot of. Despite the small injuries, Discord looked down, horrified. She was unconscious. He slowly pulled her close, avoiding contact with the necklace. He then noticed something, her cutie mark was gone, he had no idea what to do. He figured he would just talk to Twilight later or something. He decided to stabilize her wings to get his mind of that, not that it was much better.

He put a bandage on her wing making sure to do it right, after that fed her animals.

He sat on her floor and watched her peacefully until something unusual happened. Her coat turned dark and her eyes opened but had the red pupil, the green glaze and purple smoke. An evil grin passed her face as she slowly stood up.

"You can't save her, she is mine. Don't waste your time on something you can't have. She will never love you for she doesn't have enough time left, better hurry so the pain will be quick," the voice came from Fluttershy but it was not her own, this voice sounded grim and dark. After the words were spoken, the eyes faded to normal as did her coat colour but as her appearances went back to normal so did her strength. Fluttershy, the true genuine Fluttershy, collapsed beneath her feet.
Discord quickly caught her, knowing it was over but was still frightened.

Discord needed to relax but wanted to keep and eye on Fluttershy. He materialized them both to her bedroom and tucked her in on one side then climbing in on the other. He used his magic to pull the blinds so it was dark but kept her nightlight on in case she woke up.

Discord was asleep when Fluttershy awoke with a pain in her wing, yet it was durable. She remembered why she had that pain, Rainbow. She turned to her left, surprised to see Discord by her side but didn't mind. She just lay back, realizing how fast her life had changed in the span of only a few days. She had no memory of what had happened in her living room but felt that if Discord was here it must've been bad.

Knock Knock

Fluttershy heard a knock at her door downstairs. She carefully and quietly walked down her stairs to the door, she opened it to be blinded by light and to see Twilight looking frantic.

"Princess Celestia wants to see us right away!" Twilight alerted Fluttershy.

"Right now!?"

"Yes! Now lets go," Twilight said frantically.

"Ok, I'm coming." Fluttershy shut the door behind her, concerned if Discord might worry but figured he'd be alright.

The mane 6 got aboard the train, it was quite awkward between Fluttershy and the others especially Rainbow Dash. Rainbow walked to Fluttershy's seat.

"Hey," Rainbow said trying to start conversation.

"Hi," Fluttershy replied still looking out the window.

"You ok? I...I'm really sorry. I didn't mean to hurt to."

"I know, and I'm fine. But Dash," she now faced her directly, "you are hurting Discord."

"But if it is just a trick an-"

"Rainbow, he has changed. I don't know why you deny the fact that I might actually have feelings for him, just leave him alone. We're both going through enough."
Rainbow slightly nodded and moved back to her seat.

When they arrived at Canterlot Palace, Celestia was eagerly waiting for them in the throne room. They burst through the doors.

"What is it Princess?" Twilight asked intensely.

"It's Cadence, she and Shining Armour and having a problem in the Crystal Empire."

"What kind of problem?" Applejack asked curiously. Celestia sighed.

"Sombra's back, and we need you girls to use your power to defeat him."
