"I just don't know what to do Spike." Twilight said to her little dragon friend as she paced the floor of her library-like house.
Spike took a moment from eating a glittering gem to speak. "Mmmph mur hun?" he asked as he swallowed his last bite.
Twilight took his question like he actually spoke. "Because, every time we get some evidence, I just feel even further from the answer."
"What? I asked if you knew if we had any juice. You weirdo." Spike walked into the kitchen to check for himself. "Weirdo." he repeated to himself.
"Yeah, it really could be anypony. But, you know, that fisher last night, he kept saying any ONE rather than any PONY. But, what could that possibly mean?" She started murmuring to herself.
Spike walked back in with a glass of yellow liquid. "Probably nothing. A few ponies here and there do that, it's not common, but it happens." He paused to take a sip. "Most griffons and dragons even say it too, he probably picked it up because he has to spend so much time buying and selling with the griffons." He walked back into the kitchen, finishing his drink, to put away his cup.
"I just, I have a feeling that we need to do something soon, you know?" Twilight looked at her whiteboard, which was still not cleaned for sake of investigation. She used her magic to make a marker draw a line from 'FIshing Pony' to various evidences that she had learned from the previous night. "I just don't get it." Twilight was deep in thought when there was a loud thud on the door. "Spike, are you expecting anypony?"
"Uhh, no?" he asked as he hopped up onto a bookshelf to see what was about to happen better. He barely got up when the door swung open, crashing into the wall as it opened fully.
A shadow loomed in the doorway. A black smoke slowly drifted in and two red glowing eyes appeared in the smoke. "Twilight." said a deep and demonic voice. "What did you do-" a yellow pony slowly stepped from the shadow. The eye glow vanished as her voice returned to normal. "-to my beloved Angel?" Fluttershy's voice still carried a tone of rage.
"Fluttershy?" Twilight asked. "What are you talking about?" her voice cracked in fear.
"It was you, wasn't it? You're the one who terrified my rabbit!"
"What? Me? No. I didn't do anything." Twilight glanced at Spike for help. He offered a shrug.
Fluttershy stood in front of her friend and loomed over her, clearly intimidating the unicorn. "You already know I'm innocent. You are to not to step hoof on my property. If you so much as think about trying ANY of your tricks, I swear to Celestia that I will end your investigation." The mare didn't wait for a response. She turned around and ran of back towards, presumably, her cottage in the woods.
Twilight turned to Spike and the two stared at each other in silence for a long moment. "I think we have our killer." Twilight said at last.
"Seriously?" Spike asked. "What makes you think that?"
"She refuses again and again to aid in the investigation, offering as little information as possible. The murder scene was found on her property, and she clearly has the means to kill and completely strip a body of all meat. Plus, she just threatened to kill us if she catches us on her property! Any innocent pony would've done everything differently. Any jury would find her guilty without a doubt after all of that."
"Yeah, whatever. Do whatever you think you need to."
Twilight used her magic to make a scroll materialized along with a quill and she began to right a request for a lawyer to Luna, hoping to keep the investigation a secret from Celestia as long as possible.
Spike shook his head. "You're serious about this?
"Hey, I don't want any other pony to be murdered. The public's safety comes before my friend's comfort."
"What if the court's ruling is innocent?"
Twilight chuckled. "Silly Spike, there's no way in tartarus that a jury would even think about that ruling. Besides, I know a few 'mental hacks', so to say, that will ensure our victory. Trust me."
"When they don't put her in jail, don't say I didn't tell you so." Spike said. He hopped down from his shelf and walked to his bed for a very early sleep.
