Hi, Lazy-ahh! Can I ask for main Mark x AMAB reader? In another universe, reader lost his Mark. He somehow travels to main Mark’s universe. Out of desperation, reader murders the other version of himself to take his place and have a second chance with his boyfriend. But it’s only a matter of time before Mark finds out.

pairing mark grayson x (alternate dimension) AMAB reader

in another dimension, you lost mark. now, you'll destroy anything—even yourself—to get him back. but when mark starts noticing the blood under your nails, you realize: some ghosts can't be buried. and some loves aren't yours to keep.

you miss him.

it’s a hollow, gnawing thing, chewing through your ribs like a starving animal, leaving behind nothing but an ache so deep you swear it’s carved into your bones. you miss the way he laughed, loud and unguarded, the way his nose scrunched when he teased you, the way his fingers tangled in yours like he never wanted to let go—like you were something precious, something worth holding onto.

but your mark is gone.

you don’t remember much about how it happened, the memory too traumatic to remember yet too painful to forget—just screaming, the metallic tang of blood in the air, the way his body hit the ground too hard, too still, the sickening crack of impact that still echoes in your nightmares. you remember clutching his face, your fingers smearing red across his cheeks, begging him to wake up, to breathe, but his eyes stayed empty, staring past you into nothing.

you weren’t fast enough. you weren’t strong enough.

and then, somehow, you weren’t in your world anymore.

you weren’t even given the chance to grieve yet, to mourn, to scream into the void until your voice gave out. one second, you were kneeling in the wreckage of your life, and the next, you were standing on a sidewalk under a sun that felt too bright, too cruel.

this universe is almost the same. the same streets, the same sky, the same stupid posters of omni-man and the guardians of the globe plastered on bus stops, their smug faces grinning down at you like some sick joke. but then you see him—mark, your mark, alive and whole and laughing, his voice ringing through the air like a punch to the chest. your breath stutters, your chest cracks open, and suddenly you’re drowning all over again.

he’s right there.

you watch him for days, a ghost haunting the edges of his life. he goes to class, he texts his friends, he flies off to fight bad guys like nothing’s wrong, like the world hasn’t ended. it seems like he had just recently gotten his superpowers, his movements still a little unsteady mid-air, nothing like the effortless grace of your mark. your mark had gained his while he was trying to save you during a villain attack, his body slamming into yours as he shielded you from debris, his eyes wide with panic and determination as his powers finally sparked to life. you’d been walking toward a comic store to buy the latest issue of seance dog, his hand warm in yours, his voice teasing as he argued about which volume was better—as cliché and romantic as the scenario was, it was yours. but this mark wasn’t your mark. he didn’t have the memories you two shared, the inside jokes, the quiet nights pressed together under the glow of his laptop screen. he just lived his life happily and heroically, like he didn’t die in your arms. like you didn’t lose everything.

and then you see him. no—not him. you.

the other version of you in this dimension. it seemed like you didn’t get superpowers, didn’t go through the intense training that carved your body into something sharper, something meant to survive. you were... normal. soft in a way you hadn’t been in years. this version of you didn’t get to go on dates where you and mark just flew through the vast, endless night sky, the air cold and biting as you clung to him, the world below reduced to scattered lights while above you, the cosmos sprawled out in all its glory—endless stars, streaks of auroras painting the dark in rippling greens and purples, depending on where the two of you decided to go that night. you didn’t get to fight side by side, didn’t get to know the rush of battle, the way mark’s laughter would cut through the chaos as the two of you pulled off some stupid, reckless stunt, the way he’d press his forehead to yours after, breathless and bleeding, whispering, we make a good team.

but this you—this soft, powerless, ordinary you—was the one who still got to hold mark’s hand. who still got to kiss him goodnight. who still got to exist in a world where he was alive.

it’s not fair.

you don’t plan it. at least, you don’t think you do. but when you see them together—mark’s arm slung around his shoulders, his smile so bright it hurts, like looking directly into the sun—something inside you snaps. something dark and cruel and selfish, something that’s been festering deep inside you, rotting you from the core, finally consumes you whole.

he was walking home alone. it’s easy. he was normal. you were not.

you remember not even letting him scream. every time the memory comes crashing back, it’s like watching a scene play out from somewhere outside your body—like you’re floating in the back of your own mind, numb and detached, as the darkness in your veins pulls your strings, as your hands move without your permission. you let it happen. you let yourself drown.

you had gracefully landed behind them, silent as a shadow. your reflection in the dim streetlights would’ve been horrifying if they’d turned around fast enough to see it—your eyes sunken, bruised with exhaustion, your lips chapped from biting back screams, your hair a mess from nights spent clawing at your own scalp just to feel something. you looked like a ghost. like something already dead.

you remember the way they turned around, playful and fond, expecting it to be mark, only for their expression to twist into surprise. then—wonder? awe? you remember feeling perplexed, watching as this other version of you lit up, rambling in passionate excitement about how cool it was to see another version of himself. you had explained, briefly, that you were a superhero in your dimension, that you fought alongside mark, and their face had glowed with admiration, with playful jealousy, with this aching, innocent want—god, i wish i could do that. i wish i could be out there with him.

then, you remember telling them, voice hollow, that your mark died. because you were too weak. too slow. too human to save him.

and their expression—it falls. their smile shatters like glass, their eyes widening in something like grief, like understanding, because they love mark too, and the thought of losing him—

you watch the exact moment realization creeps in. their breath hitches. their fingers twitch, like they want to reach for you, or maybe run. their lips part—wait—

but you’re already moving.

"but... don’t worry," you whisper, and your voice doesn’t even sound like yours anymore. "you’ll be able to fight alongside him too. it’s just... it wouldn’t be you." your hand brushes their cheek, almost tender. "but then again, we are the same person anyway, right...?"

their face twists in horror.

you don’t let them scream.

(≧∇≦)ﾉ☆

mark notices something's off.

not at first. at first, you're perfect—maybe too perfect. you know all his favorite foods (the way he likes his burgers slightly pink in the middle, how he picks the mushrooms out of his pasta but will eat them if they're chopped small enough). you remember every stupid inside joke, every embarrassing childhood story his mom told you that one thanksgiving. your hands find all the right places—the spot behind his ear that makes him shiver, the way his shoulders tense after patrol that requires just the right amount of pressure to melt away. you curl into him on the couch like a dying star collapsing inward, pressing your face into the warm hollow of his neck, breathing him in like he's oxygen and you've been drowning for months.

maybe he is. maybe he's the only thing keeping you from dissolving completely.

"you've been clingy lately," he murmurs one night, fingers tracing idle circles along the knobs of your spine. you've lost weight. his voice is fond but there's something else there now—a question. "not that i'm complaining."

you tighten your arms around him like he might vanish if you loosen your grip. "just missed you."

he laughs, soft and warm, but it doesn't reach his eyes the way it used to. "i was gone for, like, two hours."

you press closer instead of answering, your fingers twisting in the fabric of his shirt.

silence stretches. then his hand stills on your back. "...y/n?"

"mhm?"

"look at me."

you don't want to. but you do.

his brows are furrowed, thumb brushing under your eye where the shadows have grown darker, more permanent. "you look like shit." it's supposed to be a joke but his voice cracks. "when was the last time you slept? actually slept?"

you try to smile. it feels like tearing open a wound. "'m fine."

"bullshit." his hands frame your face, calloused and warm and so painfully familiar it makes your chest ache. "you're shaking. you've been—i don't know, jumpy? like you're expecting something to—" he cuts himself off, swallows hard. "talk to me. please."

the concern in his voice is worse than anger would've been. you want to laugh. you want to scream. you want to tell him everything—how you wake up choking on his name, how every time he leaves the room you're half-convinced he won't come back, how sometimes you still smell blood when there's none there.

instead, you press your forehead to his and whisper, "bad dreams."

it's not entirely a lie.

mark exhales, long and slow, his breath warm against your lips. "okay," he murmurs, like he doesn't believe you but won't push. not yet. "okay. but you gotta eat something, alright? and sleep. actual sleep. i'll be right here." his arms tighten around you. "not going anywhere."

you close your eyes.

(you don't tell him that's what your mark said too.)

(≧∇≦)ﾉ☆

it's the little things that give you away.

the way you flinch when a car backfires two blocks away—too loud, too sudden, too much like that day. how you forget cecil's name during dinner when mark mentions him, even though the other you had known him since freshman year. the way you sometimes stare at mark across the room like he's a miracle, like he's already gone, your fingers twitching with the need to touch him just to prove he's real.

and then there are the nightmares.

you wake up screaming more often than not, sheets tangled around your thrashing limbs, your throat raw like you've been swallowing glass. the images never fade—blood on your hands, mark's vacant eyes, the way his body had felt so heavy when you cradled him. you scrub your skin raw in the shower until it's pink and stinging, but the phantom stains remain. you see them in the dark, in the flicker of streetlights through the blinds, in the rust-colored water swirling down the drain.

mark always wakes when you do.

his arms are around you before you can choke out another sob, pulling you against his chest where you can feel his heartbeat—steady, alive, here. "hey," he murmurs into your hair, voice thick with sleep but achingly tender, "it's okay. i've got you." his lips press against your damp temple, your forehead, the corner of your eye where tears still cling. "breathe, baby. just breathe."

you want to sob harder at the pet name. the other you had loved it too.

your fingers clutch at his shirt like a lifeline, nails digging into the fabric as you try to anchor yourself in the present. mark doesn't complain, just holds you tighter, one hand rubbing slow circles between your shoulder blades. "was it the same dream?" he asks softly.

you nod against his collarbone, unable to speak past the guilt lodged in your throat.

"wanna talk about it?"

you shake your head.

he doesn't push. just shifts until he can tuck you under his chin, your ear pressed over his pulse point. "listen to that," he whispers. "i'm right here. not going anywhere." his fingers card through your sweat-damp hair, gentle and sure. "you're stuck with me, y'know?"

a wet laugh escapes you, half-hysterical. if only he knew.

when you finally drift off again, it's to the rhythm of his breathing and the warmth of his hand still tangled in yours—like he's afraid you'll disappear if he lets go.

(you wish you could tell him he's holding a ghost.)

(≧∇≦)ﾉ☆

he finds out on a thursday.

you don't know how. maybe he followed you when you slipped out before dawn to scrub blood from under your nails in a gas station bathroom. maybe he found the shallow grave you dug behind the abandoned church, the dirt still loose after three weeks of rain. maybe the other you's friends noticed their texts going unanswered, their calls ignored, the way you'd flinch whenever someone said their name.

but when you push open the bedroom door—still smiling, still pretending, still holding the takeout bag from mark's favorite burger place—he's standing in the middle of the room. the blinds are closed. the lights are too bright. his face is pale as milkglass.

"where's y/n?" he asks. his voice is too quiet, too careful, like he's holding back a hurricane.

your stomach drops through the floor. the bag slips from your fingers, greasy fries scattering across the hardwood. "i'm right here."

"no." his hands are shaking now, clenched at his sides like he wants to hit something. or you. "the real y/n. where are they?"

you open your mouth. nothing comes out but a thin, wounded sound.

mark's eyes drag over you—the too-sharp angles of your face that don't quite match the photos on the fridge, the way your fingers twitch toward your pockets where bloodstained gloves are hidden, the defensive hunch of your shoulders like you're waiting for the world to end. again. his breath hitches. "oh my god." his voice cracks down the middle. "you—you're not them. what did you do?"

the grief in his voice is a knife between your ribs. you can feel yourself splitting open at the seams.

"i had to," you whisper. your voice sounds shattered, like you've been screaming for years. "i couldn't—i couldn't lose you again."

"again?" his face twists like he's tasting something rotten. "what the fuck are you talking about?"

"you died." the words pour out of you like pus from an infected wound, thick and putrid with guilt. "in my world, you died in my arms—your blood soaking through my clothes, your eyes going blank while i begged you to stay—and i—" your voice fractures, "i wasn't fast enough, i wasn't strong enough, and then i was here and you were alive but you weren't mine and i just—" your knees hit the floor with a sickening crack, but you don't feel the pain. "i just wanted you back."

mark stumbles back like you've physically struck him, his shoulders hitting the wall with a dull thud. his hands fly up to clutch at his hair, fingers twisting in the dark strands until his knuckles bleach white. "so you killed him?" his voice is barely recognizable—raw and shattered. "you killed yourself just to—to what? replace him? wear his face like some fucked-up mask?!"

"i didn't want to be alone!" you scream so hard your throat tears, the taste of copper flooding your mouth. "you don't understand—you're alive here, breathing and whole and—" your voice breaks into a whimper, "and i couldn't—i couldn't keep waking up to a world where you don't exist—"

mark's crying. really crying—the kind of sobs that wrack his entire body, tears streaming down his face in hot, silent rivers. you've never seen him cry before, not even when he broke his arm during a fight, not even when his dad disappointed him for the hundredth time. his breath comes in ragged, wet gasps as he slides down the wall, his legs giving out beneath him.

"you're a monster," he chokes out, the words barely audible but cutting deeper than any blade. his red-rimmed eyes meet yours, and the look in them—horror, grief, betrayal—makes your stomach twist violently.

you collapse forward, your forehead pressing against the cold floor as your body convulses with silent sobs. the weight of what you've done crushes you into nothingness, until you're not sure you even exist anymore. the last thing you hear before darkness swallows you whole is mark's broken whisper:

"i loved him."

(≧∇≦)ﾉ☆

he doesn't turn you in.

you don't know why. maybe he pities you—sees the hollows under your eyes, the way your hands never stop shaking, and thinks you've suffered enough. maybe he's too horrified to think straight, his mind still reeling from the blood under the floorboards, the missing person posters plastered across town. or maybe, in some terrible, twisted way, he understands. because he's lost people too—nearly lost himself a dozen times over—and that kind of grief does things to a person. makes them desperate. makes them dangerous. especially if that person was the love of your life. your soulmate. your heart. your everything.

but he doesn't look at you the same.

he doesn't touch you—no more casual brushes of fingers, no more sleepy cuddles on the couch, no more pressing kisses to your scars like they're something precious. doesn't smile at your stupid jokes, doesn't light up when you walk into the room. doesn't say your name like it means something, just avoids it entirely, like the syllables burn his tongue.

you broke him.

(and you wonder, with a sick sort of clarity, if this is how your mark felt when you died in your world. if he'd screamed himself raw, if he'd begged some higher power for a second chance, if he'd have done something just as monstrous to get you back. the thought makes you nauseous. you understand now. you wish you didn't.)

you leave before he can.

you don't belong here. you never did.

the last thing you see is mark's face—angry, grieving, alive—his mouth forming words you'll never hear, his hands reaching out like some part of him still wants to catch you. then the portal swallows you whole, and there's nothing but static and the phantom feeling of his fingers slipping through yours.

(you hope, wherever you end up, that there's a version of him who still loves you. but you know, deep down, you don't deserve it.)
