The Mark on my arm means that I can't die. I'm not bargaining. You flatline me, I will come back. But I'll come back with black eyes. And then you'll all die."

Jovi's heart raced at his words, fear and determination swirling within her. She knew she had to find a way out before things escalated beyond control.

Eli, standing over Dean, narrowed his eyes. "And we'll let you go, then what? You'll just mosey on down the road?"

Dean's gaze was steely as he responded. "No. But I will be human. So maybe a few of you live. Maybe."

Monroe chuckled again, shaking his head. "You make a compelling case, and I hope you're right. Because a man that doesn't die, well, now that is a perfect lab rat." He turned his attention to Jovi, his eyes gleaming with sick curiosity. "And your daughter... now she's an interesting one. Killed one of my boys by herself, and Eldon claims she threw him through a wall with her mind. Isn't that fascinating?"

Dean's jaw clenched as Monroe approached Jovi. Her eyes narrowed into slits, her heart pounding with a mix of fear and defiance. Come on, powers, she silently pleaded, willing whatever force had saved her before to return.

Monroe leaned in closer, his voice oozing with faux curiosity. "And she's awake! Tell me, how did you manage to take down one of my guys and toss the other through a wall?"

Jovi shot him a sarcastic smile, her voice dripping with disdain. "Years of hard work. But I've gotta say, your guy wasn't exactly the sharpest tool in the box. More brawn, less brain. It's a bit embarrassing for him, honestly."

Monroe's smile tightened, the amusement fading from his eyes. "Hmm, so it was nothing to do with those pretty little powers of yours?"

Jovi hesitated, her mind racing. She truly didn't know what had happened, and she wished she had an explanation. "Your guy wasn't as good as he thought he was. Not much more to say." Dean, sensing the danger growing, cut in, trying to draw attention away from his daughter.

Monroe Styne ignored him glancing back down at the girl "She's something else. Maybe we'll keep her around. One of my sons is around her age too. You'll fit right in."

Jovi rolled her eyes dramatically gagging, her voice heavy with sarcasm. "I'd rather be sliced and diced, thank you."

She turned her head slightly, catching sight of her father's blazing eyes. There was a fierceness there, a silent command to hold on, to fight. Monroe noticed the exchange and spoke, his voice dripping with mockery. "Brave." He nodded to Eli, who immediately moved to gag Dean.

Panic surged through Jovi as Monroe returned his attention to Dean. Her mind raced, desperately trying to recall how she had summoned that mysterious force before. The headache intensified as she replayed the moment in her mind, over and over, trying to latch onto the emotions that had sparked her power. It had been desperation—desperation to save her friend—and it had unleashed something within her.

Now, with her father's humanity on the line, she needed that power more than ever. She squeezed her eyes shut, searching for that spark, willing it to ignite before it was too late.

"Alright. Let's crack this piñata." Monroe took his scalpel and goes to make the first cut. However, Dean broke one of his arms free from the restraint and grabs Monroe's arm. He then head-butted him before sitting up and grabbing a knife. He freed his other arm, just as he looked up Eli rushed at him but before the Styne could even make a move a blast of blue energy sent him crashing into the wall across the room a sickening crack sounding out the man's head at a odd angle. Dean glanced up spotting his daughter's familiar sapphire eyes, one of her hands free from its restraints and open towards him. She panted heavily still processing what she'd just done, Dean's own eyes were wide with shock and recognition but before either Winchester could say another word the nurse let out a battle cry as she grabbed a syringe and charged towards Dean. He grabbed her, slamming her onto the operating table, jamming the syringe she was holding into her neck.

Jovi hastily unfastened the remaining restraints, her fingers trembling with urgency. As she slid off the cold metal table, a wave of dizziness crashed over her, forcing her to clutch her head in a desperate attempt to steady herself. The pounding in her skull had grown unbearable, like a relentless drumbeat hammering against her temples, each thud more intense than the last. It felt as though something inside her was fighting to break free, a wild, untamed force battering against an invisible barrier. Her powers, perhaps, straining against the confines of her mind, like a caged beast clawing at its prison, desperate for release. She looked up spotting her dad holding the older Styne in a headlock choking him

"You took something from me. Now I'm gonna take everything from you." Dean hissed pressing his arm harder against the man's neck "It's too late. Your home... your family... they...will..." before Monroe could finish his sentence Dean snapped his neck letting the man's body fall to the floor. Dean then took a moment and surveys his handiwork as he panted heavily, he met his daughter's eyes, the blue having died down now returned to their usual green "you okay?" He asked her his tone firm but still full of care "I'm fine, but we are having a serious conversation when we get home" he understood that much so with a nod he then reached into Monroe's pocket and retrieved a gun. "You ready?" He questioned his daughter who nodded opening her hand at her side the sapphire wisps dancing around her fingers while her eyes lit back up, all of it seemed to feel natural to her "ready" she responded he then turned to the metal door kicking it open in a cold fury. The door flying off of the hinges.

☆

Inside the bunker, the acrid scent of gasoline filled the air as Eldon Styne doused a pile of books, flannels, photographs, and other mementos that once held meaning for the Winchesters. The liquid soaked through memories, turning them into nothing more than kindling for the fire he was about to ignite. With a flick of his wrist, he struck a match, its small flame flickering with a malevolent glow. But just as he prepared to set the past ablaze, the sound of shuffling footsteps echoed through the room.

Roscoe Styne stumbled in, his breath ragged, before collapsing against the cold stone wall. A dark stain blossomed on his back, spreading like a sinister flower where the knife was lodged deep.

"Roscoe?" Eldon's voice wavered, his expression shifting from cold determination to shock as Roscoe's glazed eyes met his, holding his gaze for one final moment before they flashed a piercing sapphire blue. The light in them faded as he slumped to the ground, lifeless.

Eldon's heart thudded in his chest, and he barely had time to process his cousin's death before he looked up to see Dean and Jovi stride into the room. They were drenched in the crimson remnants of battle, their faces masks of unyielding resolve. Jovi's eyes still burned with an unnatural, threatening blue, boring into Eldon's very soul. This was the moment she had been waiting for, the storm she had kept bottled inside now on the verge of breaking free.

"Well, there they are," Eldon drawled, though his voice betrayed a quiver of unease. "I hope you brought marshmallows." His attempt at bravado faltered as he took in Jovi's cold, blood-spattered visage. Gone was the girl of snarky retorts and sarcastic comebacks. In her place stood a warrior, every inch of her radiating lethal intent.

Dean's voice cut through the tension like a blade, his tone as empty as his eyes. "Been looking for you."

Eldon forced a smirk, trying to mask the dread coiling in his stomach. "Oh yeah? Why's that? Oh wait, you're not still sore about, uh, what's her name...?" The smirk faded as he saw the flicker of fury flash in Jovi's eyes, a force barely contained beneath the surface.

"Charlie," Dean corrected, his glare sharp enough to cut steel. "Her name was Charlie."

Eldon's lips twisted into a sneer, the words dripping from his mouth like venom. "Yeah, well. Chucky got what she deserved. Wanna know how I did her? It's a kinda funny story—"

"Shut up," Jovi hissed, her eyes blazing brighter, the heat of her rage palpable in the small room. Eldon glanced at her, feigning nonchalance as he rolled up his sleeves. "Straight to it, then. I respect that. See, you got lucky before. But this time, I'm sporting some new upgrades. My old man—"

Dean's interruption was as swift as it was brutal. "Your old man's dead. They're all dead. So you can save me the speech on the three hearts, the two spleens, the seven nipples—for the ladies... or the fellas, I don't judge. But even with all that, you still only have one brain."

Eldon shrugged, trying to maintain his composure, though a bead of sweat trickled down his temple. "So?"

But beneath his forced bravado, he could feel it—the inevitable reckoning. The Winchesters had come, and this time, there would be no escape. Jovi's eyes flared dangerously and before Eldon Styne even realised what was happening blood exploded from his head splattering all over the younger Styne along with the walls, floor and the two Winchesters. His head had been popped like a freakish blood balloon, his headless corpse falling to the floor. "That's for Charlie, you son of a bitch" Jovi spat her eyes dying down going back to their usual colour, a wave of satisfaction and content crashed over her. She felt like she could sleep peacefully knowing she'd avenged her friend

Dean's expression hardened as he drew his gun, the barrel gleaming coldly under the dim light of the bunker. He leveled it at the remaining Styne, whose face drained of color, his eyes widening in sheer terror. His hands shot out in desperation, trembling as they pleaded with the two Winchesters. "No, no, no, no, no! Don't! Please, don't!"

"Why not?" Dean's voice was low, laced with cold fury. "You're one of them."

Cyrus shook his head frantically, his eyes darting between Dean and Jovi, searching for a shred of mercy. "No. No, I'm not! Okay, I hate my family! See, look!" His voice cracked with panic as he yanked up his shirt, baring his chest to reveal smooth, unmarked skin. "No stitches! I'm not like them, I promise."

Jovi's gaze narrowed as she studied him. There was a different kind of fear in his eyes, not the cunning malice of a seasoned killer, but the raw, vulnerable fear of a boy caught in the grip of something he didn't want. He was like a cornered animal, all fight drained from him, with only the instinct to survive remaining. She could see it—his desperate desire to escape the dark shadow of his family's twisted legacy. It struck a chord deep within her, resonating with the echoes of her own past. She knew what it was like to be trapped by blood, to fight against a destiny she hadn't chosen.

Dean, however, was relentless, his boots thudding ominously against the floor as he advanced on Cyrus. "Oh, you are like them," he growled, each word a nail in the coffin. "There's bad in you. It's in your blood. Now, you can deny it, you can run from it all you want, but that bad... it will always win."

Jovi's heart pounded in her chest as she saw the void in Dean's eyes, a darkness that sent a chill down her spine. She swallowed her fear and spoke up, her voice cutting through the tension. "Dad, wait. Maybe he's telling the truth."

Dean paused, glancing over his shoulder at her. But the look in his eyes made her blood run cold. There was no warmth, no consideration—just a hollow, unfeeling stare that frightened her more than any monster ever could. For a fleeting moment, it was as if the Mark of Cain had swallowed him whole, erasing the man she knew.

Cyrus shook his head vehemently, his voice trembling as he spoke, his words spilling out in a rush of despair. "I'll do anything you want, okay? Please. You don't need to do this." His composure shattered as he began to sob, his tears flowing freely. "Please."

He wasn't just begging for his life; he was pleading for a chance to escape the darkness he had been born into.

Dean hesitated scratching the back of his head "Yeah." He paused which made Cyrus let out a sigh of relief but Dean looked back at him with zero empathy "I do."

Dean then shot Cyrus in the head, his head snapping back, killing him instantly. A hand flew to Jovi's mouth watching as the boys body hit the floor the fear still evident in his now lifeless face, her father never would've done that — well, the version she knew anyway. "He didn't deserve that" she said her jaw clenched shut while her dad stayed where he was still glaring at the bodies "he was a monster" Jovi scoffed shaking her head just as fast footsteps approached from behind her, she turned spotting Cas. He eyed her and the blood that covered her face and clothes with a look of disbelief and worry "Jovi?" She waved him off nodding to her father, Cas then looked up at Dean calling out to him

"Dean!"

Said man slowly turned to face Castiel who glared at Dean "What have you done?".

"What happened to him?" Cas asked, his voice low and troubled as he pointed to the headless corpse on the floor. He stepped past Dean, his eyes tracing over the lifeless bodies scattered across the room. Jovi shifted awkwardly, her hand instinctively reaching up to scratch the back of her neck. "...That may have been me" she admitted, her voice a fragile thread barely holding itself together.

Cas's head snapped up, his eyes locking onto Jovi's with a mix of shock and disbelief. "How did you—?"

"Turns out that little memory wipe of yours has an expiration date" Dean interjected, his gaze fixed on Cas with an intensity that spoke volumes — a silent conversation only the angel could fully understand. Jovi's confusion deepened as she glanced between them, trying to piece together the truth buried in their stares. "What memory wipe?" she asked, her voice trembling on the edge of something she didn't want to acknowledge.

Cas's glare turned icy, directed at Dean for what he had just exposed. Dean didn't flinch, his eyes still locked on Cas's. "Just a little something that was supposed to keep those powers of yours at bay" Dean said, his voice a distant echo of the man she knew. The coldness in his tone made Jovi's stomach twist with nausea. Her heart plummeted as the realization crashed over her like a tidal wave, drowning her in a flood of betrayal.

"You knew?" she choked out, her voice cracking with the weight of her anguish. Tears welled up in her eyes as she stared at her father, desperate for an explanation, for some sign that this wasn't what it seemed. But Dean's expression was unyielding, hardened by the choices he had made. "This whole time, you've been lying to my face! You sat there and told me I had nothing to worry about when all along, you knew I had these abilities! And you chose to take my own memory from me? Who does that?"

The pain that surged through Jovi was unlike anything she had ever felt before. It was the kind of pain that hollowed you out, leaving nothing but a void where trust and love had once been. The one person she had relied on, the man who had meant more to her than anyone in the world, had been deceiving her. She felt like she was suffocating, the betrayal tightening around her chest like a vise, squeezing the breath from her lungs.

"It was for your own good" Dean replied, his eyes like shards of ice, devoid of the warmth she had once found comfort in. "My own good?" Jovi let out a bitter laugh, the sound empty and broken. "Who decided that? You? Sam? Cas?" The name felt like poison on her tongue as she turned her gaze to the angel, who stood silent, guilt written in every line of his face. "You wiped my memory, didn't you?"

Cas looked down at his shoes, shame clouding his features. "I did" he confessed, the words heavy with regret. Jovi scoffed, turning back to her father, but Dean's expression remained steely, his voice unyielding. "Yeah. We all agreed it was best."

Jovi's vision blurred with the tears she could no longer hold back. "You had no right! I deserved to know who I am, what I am!"

Dean took a step closer, his presence towering over her as he spoke, his voice a low growl. "You deserved to live, Jovi. Those powers, they were dangerous, could've gotten you killed."

"But they're mine, Dad!" she screamed, her voice raw and desperate as she shoved him back with all the strength she could muster. "You don't get to decide what's too dangerous for me!"

Dean's jaw tightened, his hand flexing as if fighting the urge to lash out, the Mark of Cain whispering dark thoughts in the back of his mind. But he held back, this was his daughter, his own blood. Not some monster he couldn't care less about, he wouldn't physically hurt her even with this demonic mark on his arm. "You think I'm gonna apologize?" he spat, his tone dripping with cold menace. "Think again. I did what I had to do to keep you safe."

"Dean" Cas warned softly, hoping to pull him back from the brink, before he said something he would regret but his words fell on deaf ears.

"Safe?" Jovi echoed, her voice trembling with the pain that threatened to tear her apart. "Is that what this is? You've turned into a damn stranger, and you think I'm safe?"

For a fleeting moment, something flickered in Dean's eyes — guilt, regret, maybe even sorrow — but it was quickly swallowed by the darkness that had consumed him. "The world's a cruel place, Jovi. You need to toughen up."

Each word was like a knife, slicing through the remnants of the bond they once shared. Jovi had always known her father was tough, but this... this was something else entirely. He wasn't just hardened by the world; he had become cruel, a shadow of the man she once looked up to. The man who had once called her "Princess" with a warm smile, who had made terrible jokes just to see her laugh, was gone, replaced by someone who seemed to care about nothing but survival and bloodshed.

"Maybe I wouldn't have to if you'd just let me be who I'm supposed to be," she whispered, her voice barely audible, trembling with the weight of her broken heart.

Dean said nothing, his silence more damning than any words he could have spoken. His expression was unreadable, a mask that hid whatever remnants of humanity might still linger beneath the surface. And that, more than anything, broke her.

Without another word, Jovi turned and stormed out of the room, her vision blurred by the tears she could no longer hold back. The walls seemed to close in around her as she fled, her footsteps echoing in the empty corridors of the bunker. She didn't know where she was going, didn't care. All she knew was that everything had changed, and nothing would ever be the same again
