The slider and the mutant (Feral Leo x Reader)

Wow, Casey is lovesick.

~Casey~
"That, is one messed up raccoon." Zane says, pointing at Leo. Casey resists the urge to say "How dare you! Sensei is my father figure!".
Zane walks closer to the slider, who was currently wrestling with a towel.
"Wait a minute, this ain't no raccoon. It's a lil' red-eared slider! They slide into nearby water when they feel scared or threatened!" Zane exclaims.

"Although, I ain't eva' seen a red-eared slider like this before. And's big too!" Zane tries circling around Leo, but he's too busy thrashing around in the towel.
"Wait a damn minute!" Zane gasps. "The bandana! The stripes! The pouches! This the turtle that went missin' six months ago!" He says.

"What?" Casey draws out the vowel. "I had no idea! How-how do you know that?" He asks nervously.
"Well, I didn't wanna scare you but—"
"You're a Yokai aren't you?" Casey interrupts. Zane physically deflates. "Man! How'd ya' know?" He asks.
"Well, for starters, you always wear your soccer bracelet wherever we go, I've never seen you without it. And, what sealed the deal was when you just said 'I didn't wanna scare you'." Casey explains. "It's in every single cliche Wattpad book where a character reveals a giant secret. The author just wrote that part onto you!"

~Narrator~
Casey! Shut the fuck up and let me write!
"Right, sorry Steven!"
Thank you.
"WAIT STEVEN!"
Yes Zane? What do you want?
"Can I be named Zucchini?"
I—you know what? Sure.
"THANK YOU!" Zucchini says. Happily jumping up and down.
Now, can I continue writing—
"One more thing!"
This will be the last thing I grant you, interrupt me one more time and I will make you turn back into a girl Zucchini.
"Anything but that! I jus' wanna ask ya' if CJ could have some game when talkin' to Pineapple?"

Ha! No. I will not grant you that wish. Now, let me continue writing.

~Casey~
"So, if I take off my cloaking brooch. You won't get terrified and go 'Eek! A giant scary monster! We must call John Bishop!'." Zucchini dramatically says. Flailing his arms around.
"John Bishop?! As in the person who kidnaps Yokai to experiment on them?!" Casey squawks.
Zucchini nods slowly. "You've heard of him?" He asks.
"Heard of him?! I killed him in the future!" Casey exclaims.
Zucchini exhales through his mouth. "Oh yea...forgot you are from an alternate timeline where everyone is either your parental figure, or a person you killed." He says.
Casey shakes his shoulders, then moves to pick up Leo. Surprisingly, he lets Casey do it, curling into the crook of his arm.

Zucchini knew that Casey was from a different timeline, ever since they first met. Zucchini had noted that Casey looked so new to everything it was almost like he was out of time. And to Zucchini's surprise, Casey is out of time.

"OHMYGODTHATISTHECUTESTTHINGEVER!" A voice squeals, Casey flushes when he realizes who that belongs to.
"Hero!" Casey says quickly. "How-how did you know where I was?" He asks. Hero shrugs, "I just heard voices in here so I checked who it belongs to." She says, running a hand through his short hair, they lock eyes with Casey, she chuckles. "I'm not mad at who I found though." They say.

Casey blushes, hating the feeling of warmness crawl up his face.
"That red-eared slider! It's adorable! It's lil' bandana and pouches!" Hero squeals, staring at Leo with her bright green eyes, they're pretty, everything about Hero was pretty, from the small curls on his head to the perfect way their dark brown skin glowed when the lights reflected off it.

God, Casey was so, so in love.

"Casey!" Zucchini voice brings him back to his senses. His vision returns, Hero now staring into his eyes with an asking expression.
"Hero, is wondering if he could pet the turtle?" Zucchini says, flicking his eyes back and forth between Hero and Casey.
"Oh!" Casey exclaims, realizing what was happening. "Yea sure! Go ahead!"
