Causal Caseytello (Dona AU)

Part 2 to THIS ASK because it was getting very long and it was filled to the brim with two very deep topics. The questions from the Asks are taken straight here to be judged as anyone so pleases.

"For the Dona AU, does anything change with the China Town episode with the spirit guy or the episode during the farmhouse arc with the demon car?"

Well for one thing, I JUST REALIZED THAT I CAN MAKE THIS REWRITE CANON SO- UH- YEAH. A LITTLE BIT OF ALTERATION TO THE CHINA TOWN STORY. SIBLING LOVE FOR THE WIN!

Ykw fine. We gonna do some causal Caseytello.

The beginning of the episode is Casey is trying to show off and Donnie gets frustrated because she thinks Casey is mocking her kunoichi abilities. April snaps at them because they won't stop bickering, Casey offers an 'apology hug' but Donnie stomps off to pout at the edge of a roof. Where she (happily) spots the Purple Dragons. Letting her friends know, she hurries down to face them.

Casey (not getting the hint) CONTINUES to be a show-off and Donnie fights back with the same brash attitude. They end up letting the Purple Dragons get away and April is ticked at them. Donnie fails to apologize and tries to blame Casey. Neither takes responsibility.

Later, after her brothers get taken and they develop a plan, Casey and Donnie do their research. Then they go on a ✨rescue mission✨

The rest of the episode goes on as canon.

The first few episodes at the farmhouse are just them getting closer and THEN comes Race With The Demon. Starts out with an argument, they get run off the road, go to the farmhouse, tell the story, and Donnie complains of pain. CASEY, looking guilty, offers the massage, which has everyone giving him a baffled look as Donnie’s like, “NO?? Obvs no?? Don’t touch me you weirdo???” and then she makes a dismissive comment about repairing his dents in the Party Wagon as she leaves the room, rubbing her neck.

Then we find them chilling in the barn, alphabetically insulting each other as friendemies do. They work on the car, test the car, Casey wrecks the car (&saves an old lady, respect). He makes a comment like “Donnie’s gonna kill me,” and then when Donnie shows up, she’s more upset about the fact that he ditched her than anything else.

They get back to the farmhouse, eventually meet in the barn, and Casey awkwardly apologizes for leaving her behind. She tries to dismiss him but he pleads for her and her “sweet scientific genius.” Her beak reddens but she pushes his face away, nonchalant as she agrees to try out a “crazy, awesome idea.”

✨They build and drink coffee together like friendos ✨

Insert the VIP of the farmhouse arc: DR CLUCKINGSWORTH. M.D.

Then we introduce The Turtleracer. Head on the road. And take on the Speed Demon! (Where Casey actually follows the plan, shocking)

Donnie jumps on a speeding car, because these children are both apparently adrenaline junkies, and tears the human out.

AND THEN- OH NOOO- SHE GETS EATEN!!

And Casey. Is. Not. Having. It.

So they race! And fight! And Casey, realizing that he’s going to lose, furiously declares, “I don’t care about winning! I just want her back!” And furiously tears Donnie out of the car.

Donnie goes back to normal, Casey quickly runs over to assist her to her feet with an arm around her shoulder, and then asks if she’s okay. She says that she is and they get about two seconds to stare softly into each other’s eyes before Speed Demon runs at them.

Donnie quickly shoves Casey out of Speed Demon’s way, and then stabs into it’s maw with a vengeful, “You leave him alone!”

They hit the ground, the others ram the PartyWagon off the cliff, and victory is scored! No problems here, right? (No. Forget that)

Donnie, who was JUST demutated, fails to stand once on her feet. Casey catches her, she shakily blames it on the adrenaline loss, and then repeats the sentiment to the worried group running over. Casey dismisses the weakness topic entirely and get a conversation going about how awesome their plan was. Donnie lights up and they both begin rambling, neither noticing the way that Casey’s arm is still snuggly around her shell.

Then audience gets to see Raph and April exchange a widely fandom-interpreted Look before the black and white scene appears.

I want this to be the A Foot To Big scene that the audience ABSOLUTELY HATES because they go back to friendemies after this. There are definitely little moments where they’re fluffy and crushing for a while, but nothing super serious happens.

There’s a definite amount of crushing for the rest of the series but neither makes a real move. UNTIL!!

The Power Inside of Her. And if it’s not obvious why, then I’m going to need you to watch the episodes again cause that’s a big one.

Donnie becomes blue sparkles!! And Casey’s there to watch it!!

And now he’s depressed! Because Donnie’s dead and now they have to kill his human bestie! And when she runs at Raph (because he’s pretty insistent that she die, RIP Angry Man), Casey stands in the way and begs, “Remember Donnie!”

And it works! Yay!!

And now we move onto Tokka vs. The World where the brothers are like “I dunno maybe Donnie should sit this one out” and Donnie takes great offense and shoves her way into the field with Casey’s support, though he’s pretty “if you make us separate I will end your life.” And then Leo DOES tell him&Mikey to separate and Casey throws his mini fit. Then Donnie gives him a meaningful look and he’s like “But what about you?” and Donnie insists that she can take care of herself, to which he reluctantly agrees, and she pleas with him to stay with Mikey. Locked under her sadorable gaze, Casey gives in with a grumbled, “Only if you promise not to be stupid” to which she mockingly replies, “C’mon, Jones, it’s me we’re talking about”.

She runs off with Leo and doesn’t notice his subdued gaze following her down the hall. Mikey looks between them with squinty eyes and a loud, “Hmmm.” Casey, catching his stare, quickly begins loudly complaining about being left behind. They get caught.

*insert the events of the episode*

Then we go to The Tale of Tiger Claw. Episode events progress. Casey is warned. Donnie looks very, very worried in the background.

She tells him to take the premonition seriously.

He replies that “he’s not afraid of any dumb ol’ vision.”

She’s not satisfied but she lets it’s slide.

Insert the girls in the lab. Leo says they gonna do patrol, designates teams, but everyone’s surprised when Casey asks to be paired with Donnie. Leo looks at Donnie, Donnie gives a confused shrug, and then Leo tells him to stick with Raph. Instead of the discussion between Mikey&Leo, it spans to Raph&Casey.

They’re chillin’ in an alley as Raph side-eyes the vigilante. Casey notices and demands, “What?”

Raph asks, “So what’s up between you and Donnie?”

“Nothin’.” Looking concerned, he asks, “Why? Did she say something?”

“It’s not about what she’s saying. It’s about what you’re not saying.”

Evidently uncomfy, he causally drawls, “You totally lost me.”

“Look, man, are you going to ask her out or what?”

To which Casey jolts and falls backward into the Turtleracer with a frantic kind of “HUH?!”

The question never gets answered because Leo alerts them to the incoming danger and the conversation is dropped for a chase scene. They fight Alopex, Casey gets scratched, Tiger Claw vs Alopex fight, and then they regroup and Casey almost gets crushed.

They head back to the lair and Casey is shown to be very carefully not looking at Raph as they learn more about the curse. When Casey makes the comment about getting kissed poisoned by Karai, Donnie glowers as she puts out the fire behind him. Splinter tells them all how to break the curse and they head out.

They head off to find her, the van gets hit, and Raph chides Casey for it. Donnie immediately stands and reminds him why he needs to be there to break the curse and Casey chimes in with a firm, “So back off me, brah!” With both of them glaring him down, Raph puts up his hands in surrender.

Satisfied, Donnie sits down and goes back to work.

Raph lets his gaze slide from Casey to Donnie and then back. He raises an eye ridge. Casey stomps to the front of the vehicle.

They fight Alopex, Casey almost dies multiple times, and then she runs off. After the battle, Donnie hurries up to Casey to demand if he’s okay, a hand on his arm as she looks him over. It moves to his face as she angles it, holding up two fingers. He gives the right number and reassures her that he’s fine, only for her to be skeptical.

Leaning into her hand and glancing at their close proximity, he slyly adds, “This curse really isn’t that bad.”

She blinks, clearly frazzled, awkwardly picking up her staff and opening her mouth like she’s going question it when the blade of the staff in her other hand almost impales him in the face.

He shouts as she frantically backs up, sheepishly apologizing and promising, “I-I’ll- uh, keep my distance.”

She turns and he flails, snapping, “This curse is the worst!”

They pile into the van. Tiger Claw gives his backstory. Then captures Alopex. But- uh oh! Turtles arrive to free her!

Fighting ensues! Casey almost dies many more times!

Then he breaks the blade! No more curses!

More fighting. Tiger Claw gets no arm and no tail.

Donnie hurries up to him when all is said and done and, predictably, demands to know his medical state. He tells her that he’s both fine and curseless, and she, visibly relieved, gives him a quick peck on the cheek before pulling away and snapping, “And next time listen to the dumb ol’ visions so you STAY THAT WAY!”

She stomps back to the vehicle, leaving everyone staring dumbfounded at Casey. He looks surprised, and then grins, looking after her as he muses, “You know, Raph. I think you got a point.”

The episode pans out with him watching her leave. Many hints.

The most hinty of episodes that absolutely nothing happens with.

"I also keep thinking about how would Casey and Donnie end up together if they did and how the others would react? Like how would that play out if it does? What would be their dynamic?"

They’re openly flirty for the rest of their time on screen, but it’s never confirmed if they actually get together or not. It’s left up for the audience to decide. Inspires a great many fanfictions.

'If' they did get together, it would be after The Tale Of Tiger Claw when Casey asks her out. Donnie would be confused about why a human would actually want to go out with her and would probably need time to think it over. Over some kind of episode span, I think she'd talk to all her brothers one-on-one about it briefly and then end the episode by accepting his offer.

All the brothers know Casey well enough to be confident that he's not going to do anything unforgivable, so they're supportive enough to tell her to say yes if she wants but also that she can be sure that he will die if he doesn't accept a no as an answer.

There's a decent amount of teasing during the relationship, but they all saw this coming, so no one really gives it a second glance.

They constantly clash but are able to apologize and work out their issues. They have similar interests in tech, so they build insane, explosive, and dangerous things together. They're often chill when they hang out but willing to dip into insulting sarcasm. Casey refuses to let Donnie hear out the insecurities in her brain and Donnie never hesitates to make Casey gifts so he can live his best life.

Their favorite pastime is finding a way to rile on another up. If you ask Donnie, she'll say that "he probably did something to deserve it." If you ask Casey, he'll smirk and say, "She's hot when she's mad"

Nobody understands why they work but they do.

Okay, fine, you forced my hand but YES I listen to It's Not Like I Like You when I think about their relationship what do you want from me?!
