Discord had been trapped in his prison for a few days when it happened. Now, when you are trapped, immobile, with no-one but yourself for company, you will be alerted to any occurrence immediately. Which is why he noticed the air. It was barely there, it could only be detected if you were completely alone with no distractions. Any newcomer to the prison might have shrugged it off, but Discord knew the statue was completely flawless. No part of him would be left free.
Discord mentally smirked to himself. He didn't know exactly what was aiding his escape, but he might be able to sense it, if the statue was cracked some more. He had been too excited when he first escaped, trying to immediately plunge the world into chaos, needing to see some fun after over a thousand years of solitude. Maybe he could find a way to cause some chaos and not be imprisoned for it.
If he could have laughed, Discord would have. He would be free soon, and this time, there was no way he was going back.
Meanwhile, in Ponyville, a familiar trio of ponies were heading for Fluttershy's home. The Cutie Mark Crusaders wanted there question answered, for both the sake of curiosity, and the very off chance it might lead to a cutie mark. Either way, they wanted answers.
Fluttershy looked up immediately as she heard a rapping on her door. Getting up, she quickly dashed over and opened it, revealing the Cutie Mark Crusaders. "Girls?" Fluttershy asked, in her usual soft manner, "What can I do for you?"
"We wanna know about Discord!" Scootaloo exclaimed.
A brief look of sadness and shock passed over Fluttershy's face, but she quickly shook it off and let them inside.
"Ok, so… what do you want to know?" Fluttershy questioned.
"We want to know why he looks so… scared!" Applebloom exclaimed.
Another look passed over Fluttershy's face, but met the same fate as the first. "Well… I can't imagine stone would be very nice, now would it?" Fluttershy pointed out.
"Well, yeah, but why wouldn't it be?" Sweetie Belle asked.
"What do you mean?" Fluttershy replied, obviously confused.
"Well, why would you imprison him in stone if it's so bad?" Applebloom queried.
"Umm…" Fluttershy was at a loss for words. Why was stone the only option? "I… don't know. Why don't you ask Twilight for help? She'll know." Fluttershy pointed out.
"But she'll go on and on…" Scootaloo complained.
"Well, she's the only one who could tell you…" Fluttershy informed them.
"Awww…. Fine…" the three Crusaders groaned in unison.
"Now, now, run along. You need to ask Twilight your question, after all." Fluttershy said.
"Ok. Thanks Fluttershy!" Sweetie Belle cried as the three fillies dashed out of Fluttershy's house.
Fluttershy let out a sigh. That meeting had left her with a new topic to ponder. Why was in necessary to imprison Discord in stone? If he broke out again, he would just cause even more chaos due to the boredom inside stone. 'That was probably what set him off when he escaped', Fluttershy reasoned. Fluttershy felt tired all of a sudden, no doubt the days stress getting to her. Stumbling to her bed, she mentally promised to give this greater thought tomorrow. Flopping onto her mattress, she had no idea of exactly what her guilt-stricken thoughts were doing.
Discord could feel more cracks forming over his body, air being blown into the thin lines beginning to snake over his body. He sincerely hoped it wouldn't take long to break free, since Celestia could notice at any time. Thankfully, the cracks were too thin to be found unless anyone was looking for them, but Celestia might think he was up to something and check.
Suddenly, Discord snapped to attention. He could feel the Elements. His prison had finally cracked enough for him to sense his jailers. And what he found was confusing. He had expected some injury, or a quarrel betweens friends to weaken the magic of friendship keeping him bound. What he found, was five perfectly normal Elements, and one who was emitting more guilt than he had ever felt before.
Discord realized, with a jolt, that the one excreting the guilt was the Element of Kindness, Fluttershy. He remembered their encounter in the maze, when her acceptance of her faults and her firm belief that her friends were always going to be there for her made her immune to his mind-tricks. In anger, he simply used a touch of magic to corrupt her. He had felt a slight stab of guilt for twisting such a sweet, innocent soul, but brushed it away, having more pressing matters to deal with. Discord realized that, unlike when the two Princesses were sharing the six Elements, now the Elements were shared between six ponies. Meaning that instead of Kindness being shared between two, it was given to the kindest soul in Equestria. And sealing someone in stone was very, very cruel.
Discord sighed. He wasn't evil, just chaotic. He would have to find a way to help her. Of course, that could wait until after she freed him.
