"Indeed. My name is Leone. Leone Abbacchio. In my past, I was an officer of the law in a corrupt world. That is, until the day I took a bribe that resulted in my partner dying. I was discharged for accepting the bribe, and that eventually led me to a gang called Passione. Specifically, I was working under a man named Bruno Bucciarati, the only man I felt comfortable around. We worked to protect and collect protection money for the gang. Our last job, or at least my last job, was protecting a girl by the name of Trish Una. The daughter of Passione's boss."

"So why did you leave?"

"It's... not that simple. After killing a team of assassins that defected from our gang, we got Trish to her father. Bruno escorted her up to him alone. When they came out... it wasn't good. Our boss tried to kill both Trish and Bruno, only failing because our newest member stepped in when he did. After that, we defected to protect Trish, which meant finding and killing the boss. Only one of us refused to follow along."

"What happened after that?"

"We went to his old home, Sardinia, to use my Stand and see if we could figure out his identity. While the rest of the team was looking into an apparent fight nearby, I stayed alone. That was a mistake. I helped a nearby group of kids get their ball out of a tree. One of them was the boss in disguise. His Stand gutted me. When I came to, I was in a cafe with an officer under my table, trying to find the truth of an assault that had happened there. He was my old partner."

"Leone... does that mean..."

"Yes. I had died. After looking over my team and seeing them get the death mask I left behind, I moved on. I thought I would go to Heaven. If I did, I don't remember it at all. My next memory was waking up here in Equestria, a completely different species. And not long after, I saw a mare getting robbed. Once I got over my shock, I rushed in to stop the robbery."

"I remember this. The robber was a Stand user, so the conflict quickly escalated to a Stand battle. The robber had to be put down on-site, though not before killing two of our guards. Leone was brought before me, where I offered him a position among my guards. He took it, calling himself Blues."

"My Stand... If I can't trust you, who can I trust? My Stands is Moody Blues, hence my alias. It's able to rebroadcast a creature's actions. I've so far gotten it to go as far back as 15 years ago."

"Hold on. You said you were a completely different species. What were you before becoming a parrot?"

"... I was a human."

"A what? Is that some kind of fish?"

"Humans don't exist in Equestria. They're bipedal, like Blues- er, Leone, but that's all I know about them."

"Let me see if I can replicate my old appearance with Moody Blues."

...

"Is that what you used to look like?"

"Yes. My skin was a consistent color under the clothes, and my feet had five toes. That's all that you need to know but can't see."

"Remember when I mentioned that there's something about most Stand Users that make me unwilling to try to rehabilitate them? It's because they're typically too stubborn to change their personalities. Not because they had Stands. Because they used to be humans."

"Are humans really that stubborn?"

"Not all of them, but you'd be hard-pressed to find one that would cause enough destruction to draw our attention but still be willing to change for the better."

"I see."

"Twilight, how did you know his real name?"

"... I'm... not sure. I just looked at him earlier and thought to myself, 'Yup. That's Leone.' I don't know how I... how I... Ugh..."

"Twilight?"

"Sorry. I got a bit dizzy all of a sudden. That's all."

"Right. You haven't gotten any sleep at all, have you? Come. Let's get you to bed."

"You said that I can sleep here, right?"

"Of course. Let's get you to your old room."

Author's Note

"OMG! Twinkle Sprinkle doesn't know what human is? What about Equestria Girls?"

What about it? It's not canon to this story. Simple as that.
