Listen (F!Reader Insert)
A/N: When the movie trailer dropped, I knew there are many opportunities for angsty fan fiction, so I kind of took one. Some of the dialogue is canon, everything else is from my imagination. Anyway, getting the characters’ "character” was a challenge. I’ll appreciate any constructive criticism to improve it. Enjoy!

“So what’s your business with our friend, pal?”
Casey slowly opened his eyes, groaning through the headache. The world seemed upside-down, but judging from the ropes tying his body to a chair, he got the memo. So he was knocked out and taken into the underground subway station. The human boy grimaced; the stench reeked here.
In front of him stood four mutant turtles, in addition to the presence of a sewer rat and another human. “Master.. Leonardo?” Casey murmured as he recognized the blue eye-mask and red markings.
“Hey, did you hear that?” Mikey gasped. “He knows your name!”
Leon smirked. “And he added a nice ring to it, too.”
“So Blue does mature after all.” Splinter scratched his fur.
“Great,” Donnie rolled his eyes. “Thank you for inflating his ego.”
“Guys, come on now—,” Raph began.
“Shh. Give a minute, hermanos, I’ve got a plan.” Leon announced with confidence.
All the voices blurred. Casey glanced around groggily, only to realize there was one person missing from the group. “(Name).... Urgh…. Where’s.. where’s (Name)?”
The group quieted down.
“Oho, skipping the introductions, are we?” Leon narrowed his eyes. He stepped closer to the human boy. “You got something against her too? …I’d let it go if I were you,” he threatened.
“This is what happens when random people jump straight to asking about his girlfriend before doing introductions,” Donnie remarked. Casey panicked under Leon’s glare, especially once he saw Leon pull out his katana. “Hey, hey!” Casey shook fervently. “Hold on a minute! It’s not—.”
“My hermanos, what do you think we should do with him?” The turtle pointed with the tip of his blade.
“Ooh, ooh!” Mikey raised his hand. “Give him a nasty haircut!”
Raph thrusted his fist forward. “We could use a nice punching bag.”
“Or here’s a better idea,” Donnie pulled down his goggles, doing a quick analysis of Casey, “how about I alter his brain, so we can remote-control him?”
“Pfft. Think we’ve scared him enough, boys.” April clapped her hands, making them drop the act and fall into laughter. Raph was snickering in back, seeing Casey all pale and shaken up. “Oh man, that was good.”
“Okay, okay, okay.” Leon wiped a tear. “In all seriousness, who are you, ‘cause we need to call you something other than— I don’t know, human guy?”
“...The name’s Casey Jones—.”
“Hold up, Jones as in Cassandra Jones? Never knew she has a brother,” April asked.
“Son,” he grumbled. God, how many times would they be interrupting him? “I’m her son.”
“Guys, I think he’s gone insane,” Donnie remarked.
“Careful, Don,” Mikey hushed. “Maybe he’s got trauma, and was put up with his sister being the mother role.”
Leon scratched his chin. “Seriously? Casey— I mean, Cassandra here— acting like anyone close to a mother?”
“For the record, I’m not insane!”
“Then, explain how you might be Cassandra’s son, when you’re just about her age.”
“Woah, Donnie, don’t tell me—.”
“That I took DNA samples from his teeth while he were knocked out? Why yes, yes I did.”
Casey shook in the air, which only had the rope swinging him from side to side. “Listen! You want to know how I’m her son? Simple answer is: I’m not from your time.”
“Huh?”
“...Is this going where I think it is?” Donnie covered his own mouth with his hand.
“I know how this sounds,” Casey cautioned. “But I need you to believe me, because I’m from… the future.”
…
Once again, everyone bursted out into laughter. In fact, even Splinter was amused.
“Y-you cannot be serious!” Donnie crouched over, dying. “That’s not possible!”
“Look, person named Casey,” Raph wiped another tear, “no offense, but if you’re trying to scare us, I can assure you you’ve got better things to do.”
“No! I’m trying to warn you guys about the future!”
“Right,” Leon rolled his eyes playfully. “And uh… how do we know whether we should take your word for it?”
“Because if you won’t do something about this,” Casey’s face contorted in anger, “(NAME) IS GOING TO DIE!”
Noise slipped into immediate silence. Everyone stopped, eyes wide.
“Woah, woah,” Raph’s tone lowered, “You crossed the line there, pal.” The snapping turtle looked to his red-eared brother in concern. He found Leon clenching his hands and narrowing his eyes. “Yeah. There are other ways to get us to listen, y’know.”
“But you wouldn’t listen! And I’m not lying when I—!”
“Then, what are you talking about?!”
“Fine. Let’s start over.” Casey sighed, “My name is Casey Jones. In the future, an alien race by the name of Kraang decimated the planet. Master Leonardo gave me a mission: find the key and stop them.
When I arrived, I couldn’t recognize the place at all. Seeing Commander O’Neil, I thought she could the best person to start with.”
“What’s (Name) got to do here?” Donnie questioned.
“She—.” Casey hesitated, meeting Leon’s eyes. The red-eared slider crossed his arms. “Say it.”
“…She was killed trying to save Master Leonardo.”
