With your enemies scattered and on the back-foot, despite the two-to-one odds, you manage to find a moment of relative calm to examine the situation and develop a plan.
Your first move is to send Uno back under the floor, and damn good timing too, because as she slips beneath it, Jotaro's Stand floats over the seat Uno was on a moment ago, ready to snatch her from the lap of the passenger she was using for cover.
You're running into a problem now, though. When you swapped Jotaro back to Cinque's position, you moved him further towards the tail of the plane, while when you yourself swapped with Quattro's body, you'd moved up closer to the cockpit.
One convenient ability of Flashdance is that its range limitations aren't necessarily centered on you. Since meeting Lord DIO, you learned that most Stands can only travel a certain distance from their master. Flashdance isn't quite the same. While if you sent out one Flashdance on its own, it would be restricted to acting in a ring 7 meters in radius from you, that ring can also originate from another Flashdance.
In short, since Quattro's fallen body (you don't want to use the word "corpse," in hopes that she'll recover over time) is between you and Uno, Uno can move freely as long as she remains within 7 meters of Quattro or any other Flashdance, in spite of being further than that distance from you personally.
However, even with that advantage, Uno is at the end of your rope. She's hanging around 7 meters away from Quattro, which seriously limits her mobility in any direct confrontation with Jotaro.
Speaking of, as Jotaro sees Uno disappear into the floor, his Stand delivers a brutal punch to the floor along with an angry cry of "ORA," enough to make his own seat nearly collapse. He stops there, though- your best guess is that he realized he had no idea what sort of mechanical parts of the plane he'd be shattering by continuing to tear up the floor- and aside from that, the sudden appearance of a huge deformation in the cabin's floor has sent the passengers from the start of a panic to a full-blown frenzy. You can see them running over one another to try to make it to the cockpit, banging on the door-what are they even looking for? To force the plane to land early? Over the middle of the Pacific Ocean?
For a moment, you reflexively begin formulating a plan to use Flashdance to try to prevent the crowd from stampeding over one another, but a sudden throb in your head makes you think better of it. The worse the panic, the harder it is for Joestar and his lackeys to act- at the moment all four of them are basically pinned, Jotaro unable to attack with full force, Avdol unable to use his flames, Joestar struggling through the crowd, and Kakyoin unable to use whatever his "Hierophant Green's" power is. Plus, swapping one of them down into the midst of this crush would be an excellent weapon. Again, you mentally thank DIO's gift for reminding you of your priorities.
Next, you send Due up into the baggage compartments, snaking slowly forward to ambush Kakyoin, simultaneously swapping Tre with Cinque, leaving Tre at the feet of the crowd where Jotaro fell (and where you now think Joseph is heading) while Cinque is now beneath your original seat where the rest of your enemies probably still think you are.
In the few seconds this all takes you, you observe the battle between Avdol, Kakyoin, and Tower of Gray. The fly continues darting around Avdol, harassing him with non-fatal but no doubt painful wounds, the fortune-teller's brown cloak soaked mauve with his blood. Avdol has partly summoned his Magician's Red, its feathered hands parrying each of Tower of Gray's attacks, albeit at the cost of yet more gruesome wounds. You can practically feel Avdol's desire to unleash his power, but you know he can't- just fully summoning his Stand would subject the tightly-packed passengers to heatstroke, and letting out its full power would torch the cabin- no doubt certain death for everyone here.
"You fool! You think you can survive me by holding back? For the sake of these bags of meat!? They're all already dead anyway! Ahahaha!"
Your mind buzzes with a distant concern at Gray Fly's choice of words, but you're more focused on moving Due closer to Kakyoin, right at the edge of your range. The traitor, tor his part, seems almost like he's trying to retreat into the crowd. Cowards, all of them- cowards or idiots, in Joestar's case.
Suddenly, though, to your shock, you see a civilian seem to turn toward Tower of Gray, as if he noticed it! Another enemy? Another Stand-user on this flight by pure cosmic coincidence?
You open your mouth to scream a warning at Gray Fly, but the words die in your throat. If you give away your position, you'll be out of places to escape to! Quattro and Cinque are in your original seat, where they know to look for you. Uno is inside the plane's machinery, and aside from that right below that monster Jotaro. Due is in a damn luggage compartment right above two of your enemies, and Tre is under a crowd crush! On top of that, you'll be revealing your voice, and with it, your gender!
Perhaps if you'd had a few more moments to steel your nerves, you would have been able to take that risk for the sake of Lord DIO, but you've hesitated for far too long already. The passenger reaches out to grab Tower of Gray with superhuman speed, and Grey Fly, not for a moment considering a random rioting civilian as a threat, didn't even bother to dodge! In a split-second the fly is trapped within the passenger's three fingers.
"With your bare hands!? I don't know who you are, but you must have a death wish! Ahaha- ha?"
Gray Fly's mocking monologue stops dead in his insect Stand's mouth as, in a panic, he seems to realize that he can't move! How can a human's bare hand hold a Stand?
As one, you, Gray Fly, and Avdol seem to notice the same thing- that Kakyoin, who you'd thought had been cringing in fear and trying to escape until now, was doing nothing of the sort! That contorted expression, slipping back into the crowd… Noriaki Kakyoin had just been trying to hide his victorious smile!
Finally letting out his wide grin, he points mockingly at Tower of Gray.
"Moron,' you said? 'Dead man?' 'Death wish?' I could hardly keep myself from laughing! Considering you created the perfect environment for my Hierophant to fight in, I assumed you were talking about yourself!"
At once, you all notice the next detail you'd also all overlooked- a green tendril is hanging from the passenger's lips!
"Why you!? I'm not being grabbed by a human at all, but by Hierophant inside his body!? You self-righteous losers would dare use a civilian as a weapon!?"
"It's like you said," Kakyoin growled, his nearly sadistic grin replaced with a more serious expression, "these passengers are all dead if we don't stop you, right? I'm sure he'll be happy to get away with a few minor injuries, considering the stakes! You, on the other hand, won't be half so lucky!"
More of those green tentacles snake out from you-can't-even-tell-where and wrap around the passenger's fingers, in turn strangling and crushing Tower of Gray! Like your own Stand, Tower of Gray sacrifices durability for its unmatched speed and mobility- Gray Fly will be smashed to bits in no time!
Thankfully, Due is already in position! With no sound other than the whistling of the air, she descends from the baggage area with a crushing blow aimed for Kakyoin's cartoid! But before she can strike, she's stopped short, and a violent scorching feeling shoots across your back.
"Tsk, tsk, tsk," Avdol clicks as you realize the partially-manifested arm of Magician's Red has caught Due from behind! "Well well, mystery enemy, I was expecting you to leap out from the shadows again, and since Kakyoin here was doing such a number on your little terrorist friend, it didn't take a fortune-teller to guess you'd go for him first!"
SHIT!!! Was two vs four really too ambitious!? The Joestars are practically out of the fight, but you and Gray Fly are still completely pinned down! Swapping Due with another Flashdance would just leave that one trapped instead, and swapping with Quattro wouldn't help either- Gray Fly is gonna be defeated before you can charge in from another angle! To make matters worse, Due is being practically cooked alive just from this fraction of Magician's Red's power. Just how hot does that Stand get?
Before the situation can get any worse, though, the plane lurches, and badly. Already unsteady from blood loss, Avdol stumbles and slams his wounded hand into the plastic edge of his seat's armrest- the damage reverberates to his Stand's own hand, which twitches and releases Due!
Fate! It's fate! Fate is on the side of Lord DIO!
Due has lost her momentum and can't lay down a fatal blow onto Kakyoin, especially now that he has his guard up, but that's fine! You'll settle for second-best!
Move your ass, Cinque!
In an instant, Cinque, chilling beneath your original seat, sticks his leg out into the aisle like a schoolyard bully, catching one panicked passenger by the ankle. Simultaneously, Due reaches forward and just grazes Kakyoin's cheek- but that's enough. With a flash, Kakyoin and the civilian have swapped places. Hierophant Green, forcefully snapped out of the body where it was hiding, hangs in the same awkward position that Kakyoin is and that the civilian was in a moment ago, rocking and about to fall from Cinque's trip and the turbulence around the plane. leg out into the aisle like a schoolyard bully, catching one panicked passenger by the ankle. Simultaneously, Due reaches forward and just grazes Kakyoin's cheek- but that's enough. With a flash, Kakyoin and the civilian have swapped places. Hierophant Green, forcefully snapped out of the body where it was hiding, hangs in the same awkward position that Kakyoin is and that the civilian was in a moment ago, rocking and about to fall from
Losing his balance, Kakyoin falls back into your original seat- as Hireophant does too, you feel a sharp chest pain as it lands forcefully on Quattro's body. This swap was fully within view of Joseph Joestar, who stares at Kakyoin in confusion.
"Kakyoin!? Isn't that where the enemy was!? And… what's that covering you?"
You ignore him, focusing back on Tower of Gray. Without Hierophant to double up on his durability, the passenger is only human, and without a second's hesitation, Tower of Gray buzzes right though his fingers, tearing them apart, then up through his chin and into his mouth, before bursting from the passenger's teeth with his severed tongue! Like a puppet with its strings cut, the civilian collapses dead on the spot, falling directly onto other horrified people in the isle.
Avdol's face contorts with an incendiary rage. "You! You bastard! You'll be punished for this!"
You know that Gray Fly is your ally, but for some reason, you can't help but feel a deep anger rise up from inside you too- killing that man didn't offer the remotest tactical advantage at all!
At your half-focused order, Cinque moves in to strike Avdol, but when Magician's Red's fist blazes a fiery pattern in the air, countering the attack, Cinque ducks back and leaps from seat to seat until reaching the edge of your range and hiding there.
Seriously, Cinque!? The moment going gets tough? But… is it her resolve that's wavering, or mine? I have to finish this job for Lord DIO's sake!
Gray Fly returns to putting the pressure on Avdol, even more viciously this time now that he feels he's in actual danger. You realize another advantage- this distraction has finally taken Jotaro's attention off of Uno!
At your command, she leaps up from the floor and delivers another nasty kick to Jotaro's shins, and you hear the second one fracture! Victorious, and with Jotaro's Stand out of position, she flies up for his heart! But between you and Jotaro sits another man.
"You miscalculated, whoever you are," he cries, "with the seats empty from this panic, I have a clear shot!"
Hierophant Green rises into the air, facing away from you towards Jotaro, and presses its hands together with a green liquid flowing between them. "Emerald Splash!"
To your shock, green gems (emeralds, you suppose) burst forth from the green slime and hurl towards Uno, who's caught as blindsided as you. If you'd had the time to think of a plan, you'd have swapped in Quattro's body to literally body block, but you aren't able to react. Instead, it's Due who takes the initiative, swapping with Uno of her own free will and delivering a barrage of punches and kicks to try to deflect the Emerald Splash- but it's impossible.
Due is able to reduce the damage, reacting faster than Uno could have, but her arms and legs are still badly torn up. A split-second later, too quickly for even Quattro to have reacted had she been around, Jotaro's freakishly-powerful Stand is already in position to counterattack, and it grabs Due's head and slams it into the ground, shattering it like a porcelain doll and staining the floor with what counts for a brain in a Stand- your skull only takes a fraction of the damage, but 1/5 of catastrophic brain damage is still a massive concussion, and your field of view is filled with stars.
By the time it clears enough for you to see the basics of your surroundings, you notice that, at least, Tower of Gray has Avdol on the ropes. The Arab has been pressed up into the side window, which is nearly shattered, and his Stand's guard is as wide open as his gaping mouth.
"Time's up, Avdol! You've resisted long enough! If you're too righteous to burn these people, then I'm sure they'll have a place in Heaven waiting for you once I'm done tearing up your bloody corpse!"
Gray Fly surges forward, past Magician's Red's open hands- but stops dead!? What is it this time!?
Avdol, who before had looked completely defeated, copies Kakyoin's previous look bar-for-bar and switches to a victorious grin.
"A pesky fly like you… had ought to be caught in a bug zapper! Red Bind!"
Again, it's only now that you notice the shape Magician's Red's two seemingly-open hands had taken- they weren't helplessly waiting for Tower of Gray to fly through their guard, they were forming a net between their fingers- a net of flames! As Grey Fly flies into them, they surge to life, and he finds himself completely restrained!
That clever bastard! He couldn't use wide-range flames to attack Gray Fly, so he drew him into a short-range trap!
"Now," Avdol starts, "I'm not a righteous enough man to pass judgement on others, but I am a fortune-teller! And I have never been so sure of any prediction as I am this one- after I'm through with your scorched corpse, you can look forward to plenty more burning in Hell, Gray Fly!"
"N-no, wait! This plane will crash in a few moments! Only I can-"
Gray Fly's attempts at bargaining are stopped short as Avdol ups the intensity of his flames, burning Tower of Gray to a crisp just as surely as a bug zapper!
Ahead of you, near the cockpit, you hear an agonized scream. You turn and finally see Gray Fly himself for the first time this fight, hiding among the rioting passengers, his mouth wide open as flame spouts from his ignited tongue! After a few moments of writhing agony, he falls dead amongst more horrified civilians, who now seem prepared to tear the cockpit door from the wall.
I'm alone! I'm down my two best fighters, and badly hurt! I need to retreat and stop standing out! I can ambush the Joestar group again later!
At your command, all three off your odds slip under the cabin floor to where they should be safe, and you use the excuse of another lurch in the plane to basically fall out of your seat and slip into the aisle, trying to fit in with the other panicking passengers without being knocked over and trampled to death.
After a moment, though, you are bumped into, and hard. You've collided with the barrel chest of the 195 cm Joseph Joestar. Your concussed mind scrambles for a decent response to make in this situation.
"You're going to say 'H-hello there,' aren't you?"
"H-hello th- guh!?" How the fuck did he-
Even your thoughts are cut short as a metal fist slams into your face with violent force, sending you flying right back into your seat, barely conscious at all.
Through a sea of buzzing, throbbing, and popping stars in your vision, you can see the apologetic Joestar standing above you.
"I'm sorry, Ma'am, I swear if I guessed wrong I'll willingly jump out of this plane myself in apology!" He reaches down and brushes your hair out of your bloodied face, squinting at your forehead. "But it looks like I didn't guess wrong, did I?"
"H-how…" you manage to gasp.
"Well, it wasn't too hard. Did you even notice? You're totally soaked in the same gunk your Stand bled when Jotaro punched it out earlier… I noticed when I saw Kakyoin covered in the same stuff."
Quattro's blood? Of course… when I swapped places with her, I was under the seat where she'd been bleeding all over the floor… I didn't even consider that… none of them have ever bled before…
Blackness fills the sides of your vision… all is lost. If you could help it, you'd swap with one of your Stands and fall out of the bottom of the plane, but you don't even have the willpower to do that. As your eyes go dark, the last thing you notice is that god damned traitor Kakyoin lifting himself over the seat and above you.
"Mister Joestar," you think he says, "I know this is Jotaro's specialty, but I think I can give it a shot this time…"
When you wake up, the pain in your chest is noticeably reduced, and the throbbing in your skull is perhaps 1% better, but you have a new problem- a scorching white light in your eyes. Once you regain partial consciousness, you realize you're staring directly up into the sun and painfully roll over on your side, realizing you're lying at the wooden bottom of a small boat.
"She's up," you hear a voice say. Kakyoin's?
"Hello, little lady," comes another voice. The Americanized British accent tells you no doubt that it's Joseph Joestar's. "Can you talk?"
You remember that you hate those two with a burning passion, but you can't remember why. Trying to sit up, you respond to Joestar with a groan that perhaps sounds remotely similar to a "yes."
He seems to take it that way, as he continues. "Your friend, Gray Fly, had already killed the pilots before the fight even began. The plane crashed, and we nearly all died and would have, if it weren't for the amazing piloting skills of Joseph Joestar! We made it out, and most of the passengers survived except the ones Gray Fly had already killed, and a few who got killed or too injured to escape in the panic. We're currently in a rescue boat from Hong Kong."
Your brain is still trying to piece this all together, but as you become more lucid, you start to remember your actions more clearly, and, horrified, start putting the pieces together.
"You got quite a few people killed, working with that terrorist. But Kakyoin here could tell you, you aren't the same person with that Flesh Bud in you. Now I just need you to answer me this… how do you feel right now?"
You finally force yourself to sit up on your ass, and see your four (former, now?) enemies sitting on the boat around you. Joseph squats down in front of you, examining you with what seems to be an impartial eye. Kakyoin looks on with sadness, Avdol with pity, and Jotaro, on the far side of the rescue boat, stares you down with a vicious death glare under the shadow of his hat.
As the memories all come flooding back and you realize what you did under the influence of DIO's brain parasite in your head, how do you feel?
[] Apologetic. You're devastated not only that you let innocents die, but that you pretty badly injured both Joseph and Jotaro. You apologize in shame for your actions and beg forgiveness.
[] Apoplectic. You were mind-controlled into this, so you aren't going to waste your energy taking blame that isn't yours. The reason those people are dead, the reason that you and Joseph and Jotaro are so injured, and the one who stomped on your free will are all the same- that bastard DIO! You'll make that piece of shit pay, you swear!
[] Apathetic. What's done is done. You were helpless to resist mind control, but aside from that, you're helpless to resist DIO too… aside from that, no one can resist DIO. He's invincible. Plus, two fifths of your Stand is dead, and your injuries are probably bad enough to cripple you the rest of your life… if these people want justice, they can feel free to throw you in prison or kill you right now.
