Chapter Text
Part 1: Barbara
The sound of rain hitting the window was a constant percussion, it was a Gotham sound, as much a part of the city as the wail of police sirens and the distant echo of a car chase. From the sanctuary that was the Clock Tower, the Oracle could see a dozen digital feeds, a hundred different stories unfolding across the city. Most of them were white noise, but a few held her attention.
Tonight, her focus was on the GCPD headquarters, where her father, Commissioner Gordon, was working late. The police radio chatter was all over the place, but something felt off. Her eyes narrowed at a flicker of motion on a rooftop opposite the precinct. Barbara Gordon zoomed in on the grainy feed.
Barbara leaned in, heart in her throat. The shape was unmistakable: a man crouched with a rifle, as he lined up a shot at the Commissioner’s office window.
And then, another flicker. A shadow moving low across the rooftop gravel. Too quick for the lens to track clearly. For a heartbeat, Barbara thought it might be Batman, or maybe Huntress, but the figure was leaner and lighter.
The shooter never noticed. His eye was locked on the scope, his finger tightening around the trigger. The shadow was behind him now. In one sharp motion, the rifle was wrenched sideways, the shot never fired. The man’s grunt was cut short as he was dragged off-balance, a flurry of precise, efficient strikes following in a blur. By the time Barbara leaned closer to the screen, the gunman sprawled unconscious, his weapon scattered in pieces across the gravel.
Minutes later, the police would arrive to the unconscious gunman, and would credit the save to Batman, but Barbara knew better, she recognised that lean figure and the uncanny movement. It was her Cassandra.
It started in the months after the earthquake, when Gotham was still bleeding. The city had cracked open, homes were gone, and the people were left trying to hold themselves together. Barbara couldn’t fight in the streets anymore, but she could still save lives. From the Clock Tower, she turned her network into a lifeline, organising supplies, tracking missing families, sending messages where no one else could reach.
She enlisted helpers to keep it all running, anyone willing to move through the broken city. And that was how they met.
Cassandra looked like one of the many malnourished kids Barbara’s teams were supposed to be helping, yet she was the one offering aid. Looking no more than sixteen, she was dreadfully tiny for her age, but she was braver than anyone Barbara knew.
She never spoke a word and had difficulty understanding language, but when Barbara handed her a list of names and a map, she accomplished every task flawlessly.
It was only after a few days that Barbara realised the girl was sleeping in a burned-out café between runs, something in Barbara wouldn’t let it stand.
The next morning, she handed Cassandra a key to a small spare room above the Clock Tower. “You can stay here with me until you find a place of your own,” she’d said simply. Cassandra didn’t answer, but she held the key like it meant more than words ever could.
From then on, she became part of Barbara’s world. At first, communication between them was slow. Cassandra could follow spoken English with growing ease, but forming the words herself was another hurdle entirely. Realising that Cassandra understood movement and gesture far better than sound, Barbara began teaching her sign language, giving her a way to reply.
Officially, Cassandra was just an assistant, helping with Barbara’s chores and Oracle’s missions, but over time, Barbara stopped seeing her as just another helper; Cassandra had become part of a family she hadn’t expected to find again.
The next day after the foiled assassination of her father, Barbara waited patiently by the door. Cassandra could’ve slipped into the Clock Tower unnoticed, but months of living with Barbara had softened her, and the younger girl now allowed herself to be seen, at least by her.
Cassandra entered through the door after retrieving the mail, still barely a presence as always. She was meant to drop off Barbara’s stack of envelopes before heading to the kitchen to make themselves breakfast, but something in Barbara’s posture, the hardened, stare made Cassandra stop just inside the threshold.
“You saved him, Cass,” Barbara said. “You saved my father.”
Cassandra froze, clutching the envelopes to her chest like a shield. She looked down at the floorboards, unable to meet Barbara’s eyes. The silence that followed was thick, a heavy acknowledgment of the secret now exposed. Cassandra’s fingers tightened on the mails, and only gave a small, uncertain nod.
Barbara inhaled slowly, seeing Cassandra step from the shadows to protect Jim Gordon had solidified a decision Barbara hoped she wouldn’t regret.
“Cass, I’ve been where you are. I know what it feels like, to stand in the dark, trying to decide if you belong in it… or if you can use it to do something better.”
Barbara wheeled herself to a cabinet tucked against the wall. The lock clicked open beneath her fingers. From inside, she pulled a case wrapped in protective cloth, folded with care. As she unveiled the contents, the yellow symbol gleamed faintly against the grey fabric of the suit within. Cassandra’s eyes widened.
“You know,” Barbara continued, a faint smile on her lips, “it takes a lot more than a fancy suit to be a hero, but a suit can help.”
Barbara didn’t expect any response from Cassandra, but she gave the girl a moment to process the sight of the suit. Then, with a few keystrokes, she pulled up a digital archive. Photos of a younger woman in the same grey-and-yellow suit filled the screen.
“This was mine,” Barbara said, her voice dropping. “The world thinks the Batgirl mantle is dead or retired, but I never let her die. The mantle doesn’t belong to the mission. It belongs to the person who carries it.” Her eyes softened as she turned toward Cassandra. “And I think… you’re ready to carry it next.”
Cassandra stared at the photos, her breathing shallow, her body taut with something that looked like fear and longing twisted together. Her fingers curled slightly at her sides. She looked at the suit again, then away, her shoulders drawing in.
“I know,” Barbara continued, “that this isn’t an easy thing to take. It’s not just a costume. It’s responsibility, legacy, danger… all wrapped under one symbol. My time as Batgirl wasn’t just about fighting, but also about finding my own way. I want you to have that.”
She pushed the case forward, leaving it open between them, but didn’t force it. The final decision wasn’t hers to make, all she could do was to open the door for her.
For a long moment, Cassandra didn’t move. Her eyes darted between the glowing images of Barbara in her prime and the symbol waiting in the case. The Bat wasn’t just a costume, it was something living, something that demanded a piece of the soul in exchange.
Her throat worked, but no sound came. Shaking her head slightly, she stepped forward and gently close the case.
“That’s okay,” she said in response, and smiled as she closed the archive window, leaving only the dim glow of the monitors around them. Cassandra stood silently, before turning to leave.
Part 2: Cassandra
The next few hours passed as if nothing had happened. Oracle’s monitors buzzed with updates, and Barbara slipped easily back into her routine: issuing tasks, cross-referencing feeds, patching calls. Cassandra moved like clockwork, quiet and efficient as always, but inside her heart faltered.
Yet every time Cassandra moved through the room, the case on the worktable drew Barbara’s eye like a magnet, it was something she was both drawn to and terrified by.
After dinner, the day had ended the same way it began. No decision was made, no further words were exchanged about the suit, and the case remained untouched. Barbara said goodnight as usual, rolling back to her desk to continue working. While Cassandra retired to her bedroom, but lay awake in the dark for a long time, her mind in turmoil.
Then the call came through the feeds. A string of dull beeps sliced through the otherwise quiet hallway leading to the command room, accompanied by the faint, pulsing glow of red warning lights. Cassandra bolted upright in bed, her body moving before her mind could catch up. Her pulse spiked, muscles coiling as the urgent sound repeated. By the time she reached the console room, Barbara was already by the computer, the screens alive with chaos.
The air in the room felt heavier now, charged with the weight of bad news, and though Barbara’s voice was low and controlled, it was also tight with urgency.
A structural failure had caused a densely populated building to collapse. Barbara’s monitors flickered with CCTV feeds: smoke flooding the street, fire spreading from ruptured gas lines, and through the haze, armed looters taking advantage of the chaos. Men picked through the wreckage, threatening the trapped survivors who were too injured or terrified to move.
Barbara cursed under her breath. “Emergency services are still twenty minutes out.”
Cassandra stood beside her Barbara, chest rising and falling with shallow, measured breaths. She imagined the smoke and chaos even through the static feed, empathising with the trapped terror as if it were her own. Her body was stiffened, but her pulse pounded loud in her ears. Every instinct screamed for her to do something. A weight pressing down on her ribs, the knowledge that she could help, that she should.
Just as she turned to walk out of the room, Barbara called out, “Wait.”
Cassandra paused in her steps, already knowing what Barbara wanted to tell her. Her eyes darted toward the worktable again, to the case under the soft light, glowing faintly in the dark like a beacon calling her name.
“The symbol is a promise, not a prison. You don’t have to be anyone but you.”
Just the word of a promise ached her chest. Her hands still remembered the blood, the life she had taken. What right did she have to carry something meant for hope, when all she had ever been was a weapon?
But this felt different. This was a promise she wanted to be worthy of.
For a brief moment that stretched far longer than it should have, neither of them moved. Then, suddenly, Cassandra crossed the room in quick strides. She reached for the case and opened it. Her fingers hovered only a second before she lifted the cowl and pressed it to her chest, as if to feel its purpose, to understand what it asked of her.
It felt heavy, but not from its weight, but from the immense meaning it carried.
Barbara’s chest tightened with pride and fear in equal measure. She nodded once, voice steady. “Go, Batgirl. You won’t be alone in this. Not ever.”
Cassandra slipped into the suit. It didn’t fit her build perfectly, but there was no time to worry about that. With a swift adjustment to the gloves and belt, the new Batgirl turned toward the open window wearing her own scuffed hiking boots, and vanished into the night.
/|\ ^._.^ /|\
The ruins of the building were a nightmare of smoke and dying light. Dust and ash hung thick in the air, and water from burst mains pooled around fallen debris. The air tasted like burnt metal, and every sound was pain and panic.
Barbara’s voice crackled through the comms, steady but laced with concern: “Be careful, Cass. All I have is the camera on your suit, I don’t have any other cameras in there, so you’re on your own. Watch out for collapsing beams and shifting floors.”
The first looter barely saw her before she dropped from the broken upper floor above. A single strike disarmed him, a second left him unconscious. Two more rushed from the smoke, knives flashing. Cassandra flowed between them, redirecting their momentum, dropping them both with bone-snapping precision.
The last man swung a crowbar wildly. Cassandra caught it mid-swing, twisting until he screamed and fell to his knees. The noise echoed off the shattered walls. When it faded, only her breathing remained.
“Good work on the thugs,” Barbara said in her ear. “My sensors are picking up heat signatures deeper inside.”
Cassandra turned, moving deeper into the wreckage.
She found a mother and a child huddled under a collapsed section of ceiling. Fear lined every face, and their eyes widened in raw panic at the sight of her. Cassandra crouched beside them, her hands moving slowly and deliberately to ensure her posture remained non-threatening. When the weak, flickering light finally caught the yellow Bat on her chest, the recognition hit them. The palpable fear in the space eased, replaced by a desperate, fragile hope.
The boy stared at it, eyes wide. “You… you’re Batgirl?” he whispered.
Something inside her tightened. The name felt too big, too bright, a heavy legacy she had no right to claim. But seeing the desperation in his face, she knew the identity wasn’t for her — it was for them. The necessity of the role clicked into place, bringing a deep, steadying peace.
Cassandra nodded once, then braced her shoulder against the buckled steel beam. Metal shrieked, concrete crumbled, and inch by inch she made space for them to crawl free.
When they were safe, she heard a groan from behind the rubble. One of the looters she’d fought earlier lay bleeding and barely conscious, his friends had left without him. Without hesitation, she dragged him clear and used a torn strip of cloth to bind the wound.
The man stared at her through dazed eyes, confusion overtaking fear. “Why…?” he rasped.
Because no one had saved her once. Because mercy was harder than fighting. Because this was the promise.
Cassandra didn’t reply. She just met his gaze, steady and calm, before lifting him with a smooth motion and carrying him to the clearing outside the rubble.
As the sirens finally began to echo in the distance, Cassandra ignored her instinct to vanish. She turned and plunged back into the wreckage, heeding Barbara’s every piece of advice and insight derived from her sensors. Actively cooperating with other rescuers, she directed the recovered victims toward the sounds of approaching help. She stood tall at the building’s entrance, the symbol on her chest glowing faintly through the haze, a beacon amid the ruin, ensuring every survivor was accounted for before the authorities took over.
“Good work, Cass,” Barbara’s voice said in her ear. “Gotham isn’t just shadows; it’s people. Hurt people. Desperate people. Batman sees criminals to fight. We see lives to save. And sometimes? Saving a life doesn’t mean breaking bones. Sometimes it’s standing where they can see you, reminding them they’re not alone. Gotham needs someone to remind it there’s still hope out there.”
By the end of the night, Cassandra’s eyes were finally open to the fragile stories of the people. She began to see more than just threats and targets; she saw lives, often broken and desperate. For the first time, she understood now that being a weapon was a chose, but she could now choose a different path: to become a beacon of hope for others.
