Work Text:
Leo couldn’t remember what happened after. All he could remember was being separated from Mikey and Donnie while running away from a Kraang like train monster with Casey which leads him and the future boy to fall into the ground.
And even though he’s ok right now {thankfully not breaking his arm} he is also glad that Casey is ok too but then things start to go wrong.
“Mikey? Donnie? Are you guys there? Answer me?” Leo said on the communicator while also making sure that he didn’t broke an arm.
But then Casey removes the mask on his head and slides down a pile of rubble with a annoyed look on his face. And surprisedly, he looks very annoyed at Leo.
Because up to that point, he saw Leo as the greatest ninja the world has ever seen thanks to his experience with Sensei Leonardo from the future. But it seems like its not going to be good.
“What the heck was that?” Casey asked with a angry voice.
“Some kind of Kraang looking monster possessing a train?” Leonardo replied.
“No I meant you! Why weren’t you listening to anyone?” Casey said with a now angry look on his face.
“I was trying to get everyone to the other side.” Leo said with a worried look.
“Yeah, I’m sure that plan worked well” Casey said being sarcastic.
“But I was doing everything right. How could this go horribly wrong?” Leo asked Casey.
“Well maybe its because you didn’t listen to anyone or your brothers!” Casey said being more angry.
“But I’m supposed to be the greatest ninja the world has ever seen. You said.” Leo said still being idiotic.
“I was wrong.” Casey said sitting down.
And hearing what the future boy said causes Leo to be confused as thats what he’s been told by that kid but then he was hit with the most devastating and cruel truth of not only himself but everyone else he loved
“YOUR IMPULSIVE! YOUR ARROGANT! AND YOU DON’T REALISE THAT YOUR ACTIONS WILL CAUSE SOMEONE THEIR LIVES!!!” Casey said as he sees Leo turning away basically trying to not listen to what the kid’s saying.
“DO YOU WANT TO KNOW WHAT HAPPENED TO YOUR BROTHERS IN THE FUTURE? They died, everyone dies fighting the kraang.” Casey said angrily. And this causes Leo to realise that because of him, his family dies in the future but he still tries to ignore what Casey’s saying.
“The world needs master Leonardo, and all we got is this guy.” Casey said as he tosses the photo of Leonardo, Raphael, Michelangelo, Donatello, April O’Neil and Splinter away before he runs off to find a way out.
And after he does Leo grabs the photo and starts to look at it and realises how much of an idiot he has been up until this point.
————————————————————————————————————————————————
It wasn’t until a few minutes later, that Casey finds a elevator shaft which he uses to climb up to the top level, while also refusing to look at Leo who is still looking at the photo and regretting all of the impulsive and Arrogant things he has ever done.
And by the time Leo got up and learned from his mistake, the boy was gone. But then he sees that Casey has climbed through the roof and so decides to follow him to tell him that he has learned his lesson of not being a good leader.
————————————————————————————————————————————————
And so after a lot of climbing later, Leo finally makes it to the top where he sees that the entire building has been covered in Kraang tentacles. But he decides to ignore that and find where the kid is.
But luckily a few second later he was able to find Casey who is just looking at the Kraang tentacle while also pretending to not listen to him.
And so Leo talks to him while walking towards the kid.
“Casey listen. All this time I thought that my brothers needed me. But the truth is, I needed them. And I know that I’ll never be like me from the future but I’m still sure that we can stop the Kraang togeth-“
“Fight me.” Casey said interrupting what Leo was saying.
“What?” The blue banded turtle said. “I said fight me Leo! Prove that you are not like the sensei I grew up training and that you are just an impulsive and arrogant liar.” Casey said holding his weapon at Leo.
“Hey lets just calm down ok, now need to fight huh? Lets just talk this over with some cup of tea.” Leo said nervously.
“No! We are not going to have tea. We are going to fight. You and me, thats right, we having it now! Come on, come on!” Casey said being blinded by rage.
And so the kid charges at Leo with his weapon and this causes the red eared slider turtle to dodge the attack.
And even though Leo doesn’t want to fight anyone especially Casey, it seems like he has no choice but to do so. And so he pulls out his sword and has the battle with the kid.
————————————————————————————————————————————————
Meanwhile back at the busted tank, Donnie and Mikey were still waiting for April and Splinter to show up and rescue them but it seems like that it might be impossible.
“Don’t worry Donnie I’m sure I can get us out of here with my mystic hands.” Mikey said. And so he uses his hands to do something but just like last time it fails and this causes the box turtle to think that Casey was wrong about him summoning portals
And seeing that their gonna die in this tank, Mikey shakes Donnie really hardly.
“This is it Donnie! We’re gonna get crushed!” Mikey screamed.
This was it for them, their gonna die as Donnie has never been this scared like this before but it is a fate worse then deat-
“Knock knock”
“April?” Mikey said. That’s right it was April and Splinter to the rescue as they use the blue serum that April stole from her high school’s laboratory to get rid of the Kraang tentacles which frees the turtle tank.
And so after that, Mikey and Donnie were happy to see that both April and their dad had save them. “Oh and uh by the way, where’s Leo and future boy?” Splinter asked. “Somewhere up there.” Mikey replied pointing at the top level.
But then they hear the sister kraang coming for revenge of what April did to her face and so they run up the stairs to find where Leo and Casey are. Not knowing that there was a fight between them happening there.
————————————————————————————————————————————————
Leo was still in battle with casey with the sword clanging and banging and all sorts of noise. And because of this, he couldn’t here Donnie asking his twin brother if he is ok.
“Leo, are you ok? We’re ascending from the stairs but hopefully if we don’t have a lot of interference then we should be able to reunite.” Donnie said. But not before the whole family sees Leo battling Casey and watching it while also being worried.
Because why are they fighting? Why does it look like that Casey wants to kill Leo? And why is Casey still saying the words “impulsive” and “arrogant” to him?
And whats worse is that like Donnie, Mikey and Raph, Leo lost his powers so he couldn’t portal hismelf out of this battle. And whats even more worse is the fact that Casey can turn himself invisible which causes Leo to get punched and smacked around a bunch of time.
He was getting confused, this kid is beating him and he’s not sure if he should be proud or scared of this fact.
But not before there turtle gets jumpscared by the kid and he slashes Leo’s arm with his weapon and this causes Leo to fall onto the ground and drop his sword. And when the red eared slider turtle tried to grab it, it was too late as Casey already picked it up and throws it away the same way he did to that photo.
“Leo! Move!” Donnie screamed.
“Yeah get out of the way dude! He’s going to kill you!” Mikey also screamed
But he didn’t here what they say as his ears were ringing and he was looking at his arm now heavily bleeding but not before he sees Casey walking towards him. And damn does the kid looks scary with his mask on.
“Hmm, guess like I was right. Say goodbye you fake and idiotic hero.” Casey said as he is about to do the finishing blow on Leo by slicing his arm open with his weapon.
But before he could do that, someone screams
“STOP!”
————————————————————————————————————————————————
It was Donnie who said that. And so he uses his bo staff to grab Casey’s weapon and pull it away from him.
“Casey look. You need to stop this madness right now.” Donnie said.
“Why? He’s an impulsive prick, who deserves to die. You guys see him like that too right? He’ll never be a good leader and he’ll never be good like you guys!” Casey said still being angry.
And hearing him say that, causes them to realise that the reason why Casey was trying t kill Leo is because of the fact that Leo was nothing like his sensei.
But despite being reckless and irresponsible, Leo still cares about his family.
So just before Casey was about to attack Leo again, {without his weapon.} Donnie says “wait” to the kid and this causes him to see the purple banded turtle.
“Look even though Leo’s my dumb dumb brother, you must realise that he’s just doing his best as a leader now that Raph’s out of the picture. And even though it pains me to say this. I support him as a leader since I am his twin brother.” Donnie says to Casey.
“Yeah, without a leader, then we will get killed. So its better to have one rather then none as that might be bad if we lose another leader since Raph is gone.” Mikey also says to Casey.
“Plus he’s doing his best to protect his brother. And he’s doing the stuff that Raph wants him to do, which is to grow up and become a better leader. And as your future commander, I tell you to look him in the eye and admit you were wrong.” April also says to Casey.
“And future boy, listen to me. I was like him when I was still human. When I was this superhero called Lou Jitsu. I used to be Impulsive and Arrogant too. But after being mutated by Draxum alongside the 4 turtles. I’ve realised that its not always about you who does the work, but also your loved ones. And is this what your sensei wanted? To kill his past self just because he was acting like a idiotic leader?” Splinter also says to Casey.
And hearing what his family is saying gives Leo the courage to talk to the kid too.
“And what do you have to say about that Non Sensei?” Casey asked Leo still being angry at him.
“That’s what I’ve been trying to tell you Casey. Like you said before, I’ll never be like future me because to you he’s a hero to everyone while I’m not. But I still care about my family to either be impulsive or arrogant. So I’m reall you this. I’m proud to be a leader and you. A-and I’m sorry for nearly getting us killed. Please forgive me.” Leo said to Casey while holding his bleeding arm and having tears in his eyes.
And upon hearing what everyone including Leo was saying causes Casey to remember his last time interacting with the Leonardo from the future. As it was the master’s choice to stay behind so that his son can go to the past and stop everything that happened in the future.
He was blinded by rage to realise that he was about to kill Leo. That he would be the one to chop of his arm.
“No. What was I doing? I-I.” Casey said as he starts to realise what he was doing.
“It’s ok Casey. Just let it all out. And besides it’s not even your fault. It’s mine.” Leo said to the kid as he tries to comfort him.
And this causes the kid to also tear up so much that he takes off his mask again and hugs Leo, which causes the red eared slider turtle to be surprised about it. Until he hears Casey talk to him while crying.
“No, Leo. This is actually my fault. I’m so sorry for calling you impulsive and arrogant. I was just angry at you because, up until that point I thought you were like my sensei. The Leonardo who was brave, heroic, makes a lot of dad jokes and saved a lot of peoples from dangers and threats. But now I see that even though your not like him, well your starting to be like him with trying to save your brothers and being a good fighter. Will you forgive me for saying those 2 things to you dad?” Casey said with tears in his eyes
Everyone was shocked at Casey calling Leo “dad” like, was the Leonardo from the future, his father figure? Or does the kid look up to him as one?
But never-mind that as this causes Leo to also have tears in his eyes and even hugs Casey back because he could tell that Casey has been through a lot of messed up stuffs in the future.
“Yeah I forgive you Casey.” Leo said and so they continue hugging until Leo sees that both Donnie and Mikey are ok.
“Wow, never knew you like hugs Nardo.” Donnie said to Leo. “Yeah” Mikey said while agreeing with Donnie.
“Man I’m so glad that you guys are not dead.” Leo said as Donnie and Mikey joins in on the group hug. “Ditto” Mikey said while joining in the group hug.
“Ok now thats out of the way. We still need to find Raph.” Leo said breaking off the group hug.
“But where Sensei? I don’t see him anywhere and I’m worry that the other Kraang zombies might be there.” Casey said to Leo nervously.
“Don’t worry kid, because I’ll let Donnie do the work.” Leo said which makes Donnie happy.
“Hahaha yes! I knew my scientific brain would be good for this job!” Donnie said happily as this also causes Casey to smile at Leonardo. As the kid is glad that he is starting to act like a good leader.
And so the mad dogs continue on their search for Raph and hopefully see if he is ok.
But what they don’t know is that after they find him, everything goes wrong.
