Exclusive note for here: A while back I posted this in its completion over on AO3. I actually had forgotten I never put it here. If you want to read the already completed story as well as its one-shots, look over there. User: FayTheGay

Keep in mind that while I will post the whole story here I won't be posting the one-shots.

READ WARNINGS

So… this was supposed to be a one-shot follow-up closing for FITHOTM but sort of spread out into more. Almost every single chapter of this short story sequel has trigger warnings. There are a lot of dark themes in this fic.

Trigger Warning: Discussions of non-consensual sex.

Usual warnings of Gabriella's insanity and angelcest treated like incest.

*~-.-~*

Gabriella shifted restlessly as The Mark burned at the base of her wings. A dark promise older than time.

Her safety net.

Oh yes. The Dark had tried. She had attempted to twist and warp Gabriella the moment that the lock touched her Spirit. But Gabriella was strong.

You are truly lost.

"No." She pushed away Life's lie. A false whisper. She was fine. She was okay. Lucifer was a threat to her life but she would be safe for as long as she had The Mark.

Safe. She thought as she stared at the final two Spirits in this part of Hell.

Deanna, head raised on the table to watch Gabriella pace. Defiant even after hundreds of years.

Saved by Michelle and free from ever being demonized.

The little traitor bastard Brendiel who hadn't stood a chance the moment she found out what he had told Deanna.

"You hearing voices again?" Deanna mocked from the table and Gabriella's lips curled in a cruel smile.

"Say that again, Deanna. Please. I've been ever-so-bored."

"What'll you do? Rip me apart again? Torture some illusionary Cass in front of me? You've done it all. You're an old dog, Gabbie."

"Shut. Up." Gabriella stomped over, slamming her fist into the center of the woman's Spirit to relish in the bloodcurdling scream that accompanied it.

'I want to show you something, Gabbie.' She jumped, recoiling away when Lucifer's voice penetrated her senses.

Safe.

Deanna started laughing, rolling in on herself the best she could in her restraints and grinning blood stained teeth at Gabriella.

"Is it Lucifer? He doesn't love you, you know. You're a tool to him."

"If you don't shut the fuck up I will being your sister here and fuck her while you watch!"

"Empty threat. You wouldn't ever risk Sammy knowing what you've done to me. You need her to love you or you're nothing but a psychopath in love with her brother." This time, Gabriella ripped the other woman's jaw off before spreading her wings to follow Lucifer's connection.

She frowned at where she stood. It was Heaven.

The Garden.

But Lucifer had altered its appearances. Where The First Tree once stood, dead after Joshea's death, the entire thing had been carved and warped into what she could only describe as a throne built of plantlife.

Was he still stuck on the imagery of nature being supreme?

Lucifer was standing in front of it, all of the remaining hundred angels standing around in silence.

"Lord Lucifer." One said while Gabriella approached slowly, cloaking the Mark that threatened to give away her state to her brother.

Safe.

"Gabbie." He greeted warmly, pulling her into a tight embrace. Samantha's Spirit coming out to nuzzle against her quiet one.

Quiet. Always quiet since she took The Mark.

Their secret.

Lucifer released her and she stepped back, gaze flicking to the throne again.

"What is this?"

"The future. Death visited me."

Gabriella pressed her lips together, lifting her gaze to meet Lucifer's. "Why?"

"He told me I need to repair this world before it collapses on itself. That him and Life would allow me to do as I needed to restart humanity."

"What?" Her mouth fell open a bit and she stared at him, stomach lurching a bit as realization clawed its way into her gut.

"You're going to bring them back." She said slowly, some sort of fury threatening to escape her. After all they had done Lucifer was going to save them.

"Never as they were. Don't look at me like that, Gabriella. I know what we did and I know everything you sacrificed to give me- us this perfect world. Now it's our turn. Mother is dead, we are what this world has. But we aren't enough on our own. It's dying, Gabbie. The world is dying."

"After everything we've done you want to rewind. Become God. Let me count the irony in that, Luci."

"Not God." Lucifer hissed, eyes flashing with anger. "God allowed them to ruin Her world, Gabbie. We will never make that mistake. We know exactly what they are capable of and we will make it clear that it will never go that far."

"Are there even any human Spirits left, Lucifer? Humanity has to be built by humans. We aren't that."

"Sam is."

Sam is. Gabriella's gaze flicked to Sam's anxious Spirit. Displeasure coming off of it.

"Sam has no ovaries. She can't reproduce and even if she could, who would be the father?"

"Though I'm reluctant, we can make her reproductive system viable." Sam. "Brendiel is still possessing a man."

"Brendiel is a drooling ball of madness."

"Brendiel isn't who we need. His meatsuit is. It's Spirit still resides there."

"What does Sam have to say about this?" The look on Lucifer's face said enough, her teeth grinding together, wings flaring angrily behind her. "I want to talk to her."

"She's resting. We've had a long day."

"Lucifer, I swear-"

"You'll what, Gabbie? Kill me? We both know that's a lie."

Her blade appeared in hand and she stepped forward, pressing it against his throat. Materializing four other variants of herself to mimic the action.

She was the third from the left.

"You're going too far, Luci. If I need to kill you to stop you from hurting her, I will. But I don't want to." It horrified her how sure she was that she could. How certain she was that if he made her, she would kill him.

When had she crossed that line? When had she truly understood that she did love Sam more than him.

That she could kill him for her.

"You aren't in charge, Gabbie."

"And you aren't God! The idea that you think you are is absolute horseshit! Humanity wasn't born through rape and if you think for a second it would be any better then you didn't pay attention to the worst corruptions in the fucking human race! Let her out! Now!"

There were a hundred angels around them that said nothing. Probably fifty that would turn on Lucifer given the chance.

The odds weren't great. But Gabriella couldn't die.

"Fine." Lucifer relented after a long moment, Spirit stepping aside and allowing Samantha's free reign of their body.

There wasn't a moment of hesitation when Samantha threw herself at the correct Gabriella, pulling her against her chest with a shaky sob.

"Loki-"

"You don't have to do that. Sam, I swear I won't let him. He won't get to hurt you."

'Take Deanna.' Gabriella pushed into Lucifer's mind. 'Do whatever the fuck you want with her but don't you lay a hand on Sam's body. If you have ever loved her you'll know I'm right.'

'I forgot about your pet project. Sam won't forgive you.'

'If she ever learns about Deanna, she won't forgive me anyways. We're monsters, Luce. But I know you love her. If you hurt her, you'll regret it.'

'Very well.' Lucifer's Spirit moved back and Samantha stumbled a bit as he completely vacated her, Gabriella tugging Samantha's face against her chest while she stared in awe at her big brother. Big, beautiful wings. Charm and peace radiating around his being as his apologetic eyes met hers.

Gabriella flew, taking Samantha down onto the Earth where they landed in a large dying field.

"He- he's gone… Lo, I don't-"

"Look at me," She tangled her fingers in short hair, meeting the wild and confused gaze of her lifemate. "It's okay. I told him to go. So we can talk."

'Lying will bite you in the ass.'

'Not if you cooperate.'

'I don't lie.'

'If you tell her the truth about Deanna, she will never let you back in. Would you really throw away everything you've built with her for pride?'

"He didn't ask."

"He wasn't thinking. Sammy, I don't-"

"Don't you dare defend him, Lo. Don't you do that." Gabriella closed her eyes, looked away. "I can't do that again."

"How long?" She asked softly, Mark burning against the base of her wings. Anger and fury licking across her Spirit and awaking it for the first time in years. "How long has he had you locked down?"

"I don't know." She admitted softly, making a frustrated noise before backing off. "I've been dreaming. We were hunting." Sam said, "Then Death was looking at me- us. Telling us we needed to return humanity or the world would die." She dropped to the ground, touching the dying grass. "When did the Earth start dying, Lo?"

"When I killed the last demon."

"When you killed Cath."

"Yes. When I killed him. I didn't know. I didn't want this, Sam. I didn't."

Except she had. To some extent, she'd wanted all of this. There was a point where it stopped being about Lucifer. About what he wanted to do for the world and what she wanted to do to the world.

When had she fallen so far off track?

"I'll fix this."

"Lo-"

"I'll fix this. I'll fix this and… I'll keep you safe. I will. I swear. I've gone too far and I need to stop. I need to be… I have to be stopped. We have to be stopped."

"Don't," Sam grabbed her arm as she spread her wings out. "Loki, don't. He'll tear you apart if he realizes what you want. He'll destroy you."

She blinked, shaking her head and smiling grimly. "If anything could destroy me, it would be The Dark. Do you want to know how far I've fallen apart, Sammy? Just how broken I am? Even the most corrupt being in existence can't damage me more than I've damaged myself. Take this." She caught the other woman's hand in hers, pressed a stone into her palm. "It's a Spiritstone. It'll bring Deanna to you. Hide and use it. Get her to safety before I do something that hurts you both again."

"Wait- Deanna's dead. I thought-"

"I lied to you. Lucifer let you believe the lie because the truth is that I relished in tearing your sister apart. I've done it for years because I can. Because no matter how much I hurt her, she will never turn. Michelle blessed her before she died. You love monsters, Samantha."

"Then what does that make me?" The once-Hunter asked quietly, staring at her with something akin to betrayal.

"I guess it depends on what you do now that you know." Gabriella smiled grimly, closing her eyes. "I'm going to stop him before he hurts either of you, though. Bye, Sammy."

In a single flap of her wings she was in flight. Finding anything with opposable thumbs in the modern times was easier than breathing and she knew not to go for Lucifer immediately.

Not when she could have help.

"Gabriella," The angel greeted her with an angel blade to her throat and Gabriella grinned, all teeth.

"Hello, Ariah. It's been a long time, baby sister."

"How did you find us?" She demanded and Gabriella snorted, looking at the angels that had joined their sister's side. A long abandoned Bunker in the maw of what had once been Kansas. Hidden from the detection of even Archangels.

Of course she knew where it was.

"I never lost you after Michelle banished you to the Earth, you arrogant little worm." Snapping her fingers, she sent the hiding once-Lucifer-loyalists flying into the wall beneath the entrance of the Bunker. "You didn't come to Lucifer's aide after he won. Tell me why."

"We didn't want him to win." The right angel spat at her, undeterred. "Michelle was meant to win that battle until you put your nose where-"

"Let's agree to disagree." She flicked her wrist, removing their voices. "You still have Spirits in your bodies. Two males and a female."

"What of the humans?"

"They might be the last hope for humanity. I'm about to do something, kiddies. Figure it out. Figure them out. They might be the new world's Ada and Steve."

"What does that mean?"

"It means I'm about to do something that will change everything." She dropped them, watching them while they shifted uncomfortably, healing damage to their Vessels and glaring up at her.

"You're going to turn. I don't believe you."

"Believe me, don't, I don't give a damn. Keep those bodies alive or this world will end." Then she was in Hell, dropping herself between Deanna and Lucifer where he was standing a few feet away.

"Gabriella?"

"Sorry, Luce. Deanna's off limits."

"Oh, that's gold." Deanna coughed from behind her and Gabriella spread her wings. Ignoring Deanna's laughter.

"What are you going to do, Gabbie? Kill me?"

"I don't know." But the Mark was burning. Tearing at her Spirit. Pushing anger and hate into her veins for the first time ever.

For the first time in her long life, when she looked at Lucifer, she didn't see him as a forbidden desire. A man she loved and wanted. What she saw was the man that had taken everything from her and still asked for more.

The man that had broken Loki and crushed her into dust. Left her a broken shell of what she had become.

Hate. Anger. Kill. Kill. Kill!

"You wouldn't try, Gabbie. Not now. Not after all we've been through."

"Sam knows the truth about Deanna. About what I did to her. About what you knew. She'll never let you back in."

"You wouldn't have-"

"When you put her in danger, Lucifer? When you threatened her freedom? Yes. Yes I would. I would sacrifice everything to protect that woman."

"You don't get to play the hero, Gabbie."

"I'm not a hero. I'm a monster. And so are you." Her manifestation appeared behind him and Lucifer took flight, shooting through the surface of the Earth as she tore after him. Catching him easy. Fast. Always fast. She caught him by his ankle and shoved him into the ground, the ground spitting up violently around them as they crashed into it, her older brother driving his blade through her heart without a second thought as she crashed down on top of him.

Silence fell like a blanket over the both of them, her gaze flicking downwards to the metal protruding from her heart.

Slowly victory warped into confusion that warped to horror. "You didn't."

"I did." She said quietly, wrapping her fingers around the hilt and yanking the blade from her own chest.

Kill. Kill. Kill!

"I knew you could do this. I knew that you would do this," She said the second part quieter when she pressed the same blade against Lucifer's heart. Brendiel's stolen body trickling blood from a fresh wound, her eyes flashing with her Spirit that was rallying with the words building in her heart. The pulsing of the Mark not enough to override her own thoughts. Her own emotions. Because she was power and she was strength. But most importantly, she wasn't sane. Leaning down, she pressed her lips to Lucifer's. Unwelcome. Unwarranted. "I knew all of the things that you tried so hard to hide. Because you're right. You don't lie. But you don't always tell the whole truth," She shifted her wings forward, used their weight to push his into dirt and roots thicker than the oldest tree. A diverse network of nature and plantlife that no human could ever truly grasp. The thing he had once fought to save. "And you stopped telling me you loved me. You stopped loving me because I loved you more than you could ever love me back. And yeah, it's fucked up. I'm a vile woman but I own up to it. All I wanted from you was for you to give a damn!"

"I do love you, Gabbie."

"But not all of me. You still look at me like I'm a traitor. Like I stole the one thing from you that Mother gave you. But newsflash, I didn't. Life gave her to me and I broke her! So, Luce. You owe me."

"What do you want from me?"

"New lives." She said quietly, drawing on the strength of her Spirit fueled by The Mark and plunging it through Lucifer's. There was a violent screech as she cut through his Spirit, breaking it apart and weakening it significantly. As his once powerful Archangel Spirit was weakened and reduced until it was no stronger than a human.

"What have you done, Gabbie!" He managed, after she caught him around his waist, dragging him back to the Earth's surface to discard him in some softer grass.

"Life was wrong. I can't kill you. And I can't die now." She wrapped her wings around herself, staring at him while he shoved himself into a sitting position, face pale from horror. "But you can and will. And you will go on and you will survive."

"This isn't life."

"It's close enough. I don't give a fuck what you do with it. You're alive."

"And what will you do? Leave me here? I won't survive like this!"

"Well, like you said. The world's dying. There are what? Five humans? Six if we include you? Looks like I accidentally shredded Brendy's meatshield. Seens like you have some work ahead of you. Assuming Sam or anyone else that hates you doesn't kill you on sight. Might think about learning to lie." She caught him by the front of his shirt and brought him to his feet, spinning him around to slice through still present wings like butter.

Lucifer wailed and she shut her eyes, basking in the joy it ignited in her Spirit. The excited movements of her Spirit within her body.

"You can't-"

"It is done." She caught his wrist and spread her wings, flying to that same Bunker where she abandoned him unconscious on a bed.

"What is this?" Ariah demanded when she landed in the main room.

"Your chance to return. Heaven is yours, Ariah. No more death to humans. Revitalize the angel population."

"What's the catch?"

"Anonymity. These three humans are free and they will not be told who is asleep in the bed. If he tells them, it's his choice. But it is not their information to have."

"What about you?"

"Hell and its Spirits are mine. Not yours. Not anyone else's. I get to do whatever I want with them and I'll leave Heaven to do whatever it wants. We don't intersect. We don't cross paths."

"What about the humans?"

"Don't slaughter them but do whatever you want. Become Gods for all I care. Samantha Winchester's Spirit is mine, though. Lucifer's Spirit is mine."

"And her sister?"

"Mine too. No buts. You get the rest of the damned human race, whatever that means in this day and age. They're mine."

"Okay." Ariah agreed quickly, wise in not angering her. After all. There were other angels she could bargain with. "Thank you, Gabriella."

"They know nothing of him." Gabriella warned one final time before returning to Hell.

Deanna was gone.

Gabriella would spend the next twenty years in Hell debating whether or not she'd made the right choices.
