[If Gabriel hadn't already planned this out in his head from the moment, he let himself out of the Impala, he'd probably be scared right now, but he knew there were only two ways this could go. Either Lucifer proves him wrong and spares him or he dies. He knew his big brother- probably better than anyone, save Michael, and he hadn't been shittin' Kali when he told her she should be scared of him. Heck, if he didn't think he was running short on time and low on options and Dean hadn't been right... He'd be running the opposite direction.
"I know you think you're doing the right thing, Gabriel, but I know where your heart truly lies."
If Gabriel had intended this to be a real fight, it would've been over right now. Archangels are bred for violence, but he had to take a stand, he had to show he'd changed his mind, finally chose a side, instead of playing like no one else's side was worth it. And this way... This way, he didn't have to kill his brother. That he couldn't do. He'd give Dean the satisfaction of being right about this much, but... He'd rather die than have Lucifer's blood on his hands.
He watched as his copy glanced behind Lucifer, practically signaling his brother to his presence there, but that didn't matter. Lucifer knew he was there. He sucked in a breath and raised the blade, expecting to have his blow stopped...
The movement from Lucifer was so fast that it surprised him. His arm twisted back as the blade moved away from Lucifer and buried itself in his chest. He choked out a gasp, staring into Lucifer's eyes and wishing he could hide the betrayed look. He'd started this. He pushed Lucifer to this end, but he'd given him the chance. No one made him do this- it was his choice.
Just as it was Gabriel's choice to die here, as a hero, rather than let himself be dragged out and gutted for being a disloyal coward.
"Here," Lucifer continued, holding the knife in place to punctuate his words, while Gabriel clung to his arm, desperately, choking out pained whimpers. The copy flickered out of existence, signaling his eventual end, as if there was any doubt of it.
Lucifer pulled him closer, placing one hand against his head. His tone sounded so disappointed when he spoke, like he didn't quite realize that Gabriel had made this easy on purpose, "Amateur hocus pocus. Don't forget. You learned all your tricks from me... Little brother." He waited a second longer, the two of them still half-clinging to each other, before he finally twisted the knife in. Gabriel finally let out a scream as his Grace exploded out of him, burning out everything but the look in Lucifer's eyes.
And then... There's nothing. No agonizing pain, no sorrow. Just... Emptiness.]
Meanwhile, on the Barge...
[A flash of light randomly lights up Level One, bright enough to send a ripple of bluish-white through entire hallway and an earthquake-like tremble that was just enough to shake that particular section of the Barge. It's just after dinner, almost 48 hours since Gabriel's disappearance. For him, it's been... A few months. He can't really seem to remember how many.
He blinked a few times, half-wondering why nothing suddenly looks like a cruise ship. And then it hits him and he breaks out in a ridiculous cackle. Still laying down, he pulls his transmitter back out of his pocket and turns it on.]
Honey, I'm home.
[There's something bittersweet in the statement right now, but... For the moment, he has to pretend like he's okay. Things ended just as they should have. Gabriel's on the Barge, all may be right with the Apocalypse back home.]
[[OOC: YEP. Gabe's back from his canon update. He's gonna be lying on the floor of Level One, if you wanna find his sorry ass on your way out from dinner, because he's... Kinda disoriented from being dead and doesn't wanna move. He'll be acting PERFECTLY OKAY about this whole thing and no one will know anything bad happened, except for the part where there's a knife-shaped hole in his shirt. Anyway. Spam, don't spam, do what you like. I'm flexible.]]
