Gotham City never really slept. It only shifted moods—from the daylight masquerade of polished shoes and business suits to the midnight crawl of whispers and sirens. For you, it was home. Chaotic, flawed, and yours. You weren’t a Bat. You weren’t even one of the shadows that trailed beside him. You were Bruce Wayne’s middle child—too independent to join the family business of nocturnal violence, too stubborn to be just another Wayne in the tabloids
But even from a distance, you were close with your siblings. You knew their secrets, covered their bruises, and made excuses when the press sniffed too close. You stayed out of the caves and gadgets, but the Bat-family’s world never truly left you alone.
Tonight proved just that.
The gala at Wayne Tower had been another exercise in pretending. You wore your mother’s old diamond earrings, your father’s polite smile, and your own brand of quiet rebellion—a sleek black dress that cut sharper than any Batarang. You’d just escaped a conversation with a snooty investor when you saw her.
Sophia Clark.
Supermans daughter.
You didn’t need the headlines to recognize her. She had that same impossible glow about her—the kind that made everyone else in the room fade to gray. Raven hair swept perfectly over her shoulder, deep eyes that looked carved out of a Kryptonian glacier, and a smile that seemed to mock you without even trying.
She wasn’t supposed to be here. Not in Gotham. Not in your city.
“Wayne,” she greeted, her voice warm and condescending all at once. “Didn’t expect to see you hiding out here. Thought you preferred the comfort of your father’s tower.”
You raised your glass, not bothering to hide the distaste in your tone. “Didn’t expect you here either, El. What’s the Metropolis golden girl doing in Gotham? Get bored saving cats from trees?”
Her lips twitched, almost smiling. “Cute. I’m actually here for work. But I guess you wouldn’t know what that’s like.”
You felt the jab land—a familiar sting. Everyone knew you weren’t part of the Bat-family’s hero club. It was a choice, but people like Sophia never saw it that way. To them, you were the privileged Wayne who watched from the sidelines.
“Yeah, I wouldn’t,” you said coolly, stepping closer. “Some of us don’t need to throw ourselves off rooftops to prove a point.”
Sophia tilted her head, eyes scanning you the way her father probably looked at villains. “Some of us don’t hide from what we are.”
The words hung there—heavy, deliberate, cruel. You stared at her, your pulse tightening. You hated the way she looked at you, like she already had you figured out. Like she’d decided you were fragile, useless, soft.
“Must be exhausting,” you said finally, forcing a smirk. “Being so perfect all the time.”
Her smile turned sharp. “You’d be surprised how easy it is when you actually are.”
You opened your mouth to fire back, but a sudden shift in the air made your skin prickle—a familiar weight settling over the room before you could place it. A presence you’d known all your life, sharp and steady, brushed against you. Then the heavy, controlled footsteps follow, each one deliberate, practiced, unmistakably belonging to someone who never needed to announce himself. And when he finally stepped into view, the presence solidified—Bruce Wayne entering the space like a shift in gravity itself. Even without looking, you could feel him—your father’s presence always arrived a second before he did.
He wasn’t loud, he didnt need to be. Power clung to him in every way. The tailored black suit, the subtle glint of his cufflinks, the sharpness in his eyes—he looked every bit the billionaire the city worshipped and the vigilante the criminals feared. And beneath it all, that familiar scent reached you: expensive cologne softened by warm leather and cool steel, a scent you’d known since childhood. A scent that meant safety, command, and warning all at once.
Bruce’s gaze flicked between you and Sophia, assessing, calculating, already three steps ahead of a conversation that hadn’t even begun yet. His voice didn’t need volume to take control.
Bruce’s gaze landed on Sophia first, his sternness easing by a fraction. “Sophia. I’m glad you made it.”
She straightened subtly—as if even Superman’s daughter felt the weight of his approval. “Thank you for inviting me, Mr. Wayne.”
Their exchange was smooth and polite. You watched it with a tightening jaw. They spoke briefly—formal pleasantries, mutual respect, nothing out of place—yet it felt like the floor was shifting under you.
Then Bruce turned to you.
And just like that, the softness vanished.
“I asked Sophia to be here tonight for a reason,” he said, voice low but final. “I need a favour from you.”
Your stomach dropped. “A favour?”
He nodded once. “She’ll be operating in Gotham for the next few months. Metropolis wants her exposed to our methods, and I want someone I trust to guide her. You.”
Your breath caught. “You want me to train her?”
“It’s not optional.” His tone left no room for argument. “We’ll discuss the details later. Not here.”
You couldn’t make a scene—not at a gala, not with hundreds waiting for a crack in the Wayne façade—so you swallowed your shock, your frustration, and your pride.
You nod meekly, “yes father” venom threatening to slip into your tone, but you knew better.
Bruce gave you one last firm look, then nodded to Sophia with that rare, respectful acknowledgement he reserved for people he saw potential in. And just like that, he walked off—leaving the two of you standing in the echo of the decision he’d made for you.
The moment he was out of earshot, Sophia exhaled sharply. “Well. That could’ve gone worse.”
You snapped your head toward her. “Really? Because from my view, it went perfectly awfully”
Sophia raised an eyebrow. “It’s not that dramatic.”
“Not that—?” You nearly scoffed. “You’re getting forced into my city, into my space, and I’m apparently your new babysitter. I think ‘dramatic’ is appropriate.”
She folded her arms and tilted her head with that familiar scowl she reserved for you only. “For the record, I don’t need a babysitter.”
“Great,” you shot back. “Tell that to my dad.”
Sophia rolled her eyes. “Look, I didn’t ask for this either.”
“Oh, I’m sure you hate being assigned to Gotham, the one city that doesn’t swoon the second a Kryptonian shows up.”
Her jaw tightened. “You’re unbelievable.”
“You’re infuriating.”
Sophia stepped closer, lowering her voice. “I’m here to do actual work. I don’t know what you’re here to do besides glare at me and complain.”
You scoffed. “I was here to enjoy one night not dealing with hero nonsense, but clearly that was too much to ask.”
Sophia’s lips curved into a slow, irritating smirk. “You know… for someone who’s not in the field, you make an impressive amount of noise.”
Your eyes narrowed. “And for someone who thinks she’s perfect, you talk an impressive amount of crap.”
For a moment, the two of you just glared—heat simmering, irritation sparking, the kind of tension that could topple buildings if either of you pushed hard enough.
Sophia finally sighed. “Look. We should at least try not to kill each other before training starts.”
You forced a tight smile. “Sure. I’ll pencil that in—right between ‘scream internally’ and ‘move to a different planet.’”
Despite herself, Sophia snorted. “You’re ridiculous.”
“And you’re in my way,” you muttered, brushing past her.
She didn’t move. “See you tomorrow, Wayne.”
The way she said your name made your pulse spike—for reasons you refused to examine.
You kept walking.
You signed up to be a lawyer and Wayne successor not a supesitter. But you knew going against your father wouldn’t be smart, especially when you knew he owned everything you aspired to uphold
You really needed that rooftop run.
Later that night, you were out on a rooftop run with Dick and Jason—your usual escape whenever the world felt too heavy to swallow.
The Gotham skyline stretched around you, sharp and cold against the midnight air. Dick ran ahead in that obnoxious, graceful way he always did, flipping over a vent like it was nothing. Jason jogged beside you, mask off, helmet clipped to his belt, cigarette tucked behind his ear because he promised he “wasn’t smoking tonight.”
You didn’t even get two rooftops in before Jason groaned.
“Alright,” he said, hands on his hips. “Spit it out. You’ve been stomping like you want the roof to file a complaint.” The sass in his tone would usually agitate you, but you had worse things that poked at you tonight.
Dick glanced back with a knowing grin. “Let me guess—Dad did something?”
You scoffed loudly. “Oh, did he ever.”
Jason snorted. “Called it.”
You launched into it before the irritation could fester any deeper and before their pestering and teasing led to an inevitable fist fight.
“He invited Sophia to the gala.”
Dick blinked. “Superman’s kid?”
Jason made a face of pure disgust mixed with a tinge of joy at your annoyance. “The dark haired one who looks like she judges people for breathing too loud?”
“YES,” you snapped, throwing your arms up. “Her.”
Jason doubled over laughing so hard he nearly tripped. “Oh, this is already good.”
Dick leaned in like he was settling in for a bedtime story. Atleast he had some manners to read the room “What happened?”
You clenched your jaw. “He wants me to train her.”
Both men froze mid-step, almost giving themselves whiplash from turning at such speed.
Jason actually choked. “He WHAT?”
Dick slapped a hand over his mouth, eyes wide in utter disbelief. “You? Train Sophia, THE LITTLE MISS PERFECT SUPERSUCCESOR?”
You groaned, dragging your hands down your face. “YES. Apparently Metropolis wants her exposed to ‘Gotham methods,’ and Dad wants someone he ‘trusts’ to guide her.” You mimicked Bruce’s voice with extra gravel. “It’s not optional.”
Jason doubled over laughing. “This is the funniest thing that’s ever happened to me.”
“Jay,” Dick warned through a laugh of his own, “be nice.”
“Why?!” Jason wheezed. “Our sister is being forced to babysit a Kryptonian princess with an ego problem! This is poetic justice.”
You shoved him lightly. “I hate all of you.”
Dick slung an arm around your shoulders. “It’s not that bad. She can’t be that annoying.” His attempt to lighten your mood faltered as you hear Jason continuing his assault on your ears with his absurd laughter.
You looked at him dead in the eyes. “Dick. She breathes like she owns oxygen.”
Jason made a strangled noise- now almost lying on the dirty rooftop. “I’m dying—keep going.”
“And she said I ‘wouldn’t know what work was like.’”
Both brothers stopped again. This time looking at you with the kind of seriousness you’d have to beat out of them during batfam meetings.
Dick blinked slowly- trying to ensure he heard you correctly. “She said what?” His tone was now rid of its playfulness.
Jason added onto the tense atmosphere cracking his knuckles. “Okay. I take it back. We’re jumping her.” The movement made you cringe, but you appreciated the thought behind it at least.
You groaned again. “No one is jumping anyone. I just… I can’t believe I’m stuck with her for months.”
Dick squeezed your shoulders reassuringly, his tone softening. “Who knows? Maybe it’ll go better than you think.”
Jason smirked. “Or maybe you’ll kill her.”
“little wing.”
“What? I’m being supportive.” He scoffed- shoving dick halfway off the rooftop “and stop fucking calling me that shit”
“WHAT? You took up my place as robin so be proud, little bitch” The chaos erupting right beside you faded into the distance as you continued your feet's assault on the Gotham rooftops in thought.
You sighed, staring out at the city—your city. The place you loved, the place she was about to invade.
This was going to be hell. It wouldn’t be long before the rest of the batcave or wayne siblings found out about the personal hell Bruce set out for you.
And your brothers? They were going to enjoy every second of it.
