A/N: Warnings for smut. Ahem. Yeah.


Kael comes back to the present with new eyes; human memories mixing with angel.

Lucifer doesn't take his eyes off hers as he digs into the front pocket of his jeans and holds something out to her.

In a tiny vial, buzzing and glowing bright blue in reaction to being so close to its owner, is her grace.

Kael doesn't take it straight away. Instead she says, her voice a little broken, "You killed Gabriel?"

Lucifer nods, his mouth a thin line. Of course she knew already, but it's different when she can remember their friendship. He was a good kid. She and Luci had practically raised him.

She tries her best to shake away her grief. "Why didn't you just tell me who I was at the start?"

Lucifer shakes his head a little; looks at the floor. "I was… You said you wouldn't forgive me." His voice is barely audible over the roar of holy fire.

Kael reaches out to him, fingertips tilting his face to look at her once more. "Luci, you are so stupid sometimes, you know that?" she breathes, and before he can retort, her lips are on his.

It only takes him a second to recover, one arm tightening around her waist and the other reaching to wind his fingers into her hair. The kiss is long and slow and she can feel him smiling into it.

The break apart, Kael a little breathless, and she takes her grace from his hand. "It's restored?" she asks, a little in awe as she studies it.

He nods. "It grew stronger with time. Being near you helped."

Kael opens the vial and her grace flows straight into her without hesitation. It wraps around her and melds to her soul and her vision turns white.

She feels whole.

When she sees again, she sobs a little with horror as she takes in the state of Lucifer's grace. Once a gorgeous icy blue, brighter than any angels'; now an ugly dark red. The way it seeps around his form looks like he's bleeding, the source a jagged wound where the angelic equivalent of a heart should be – a crudely cut hole where his healing grace is missing.

"Doesn't that hurt?" Kael whispers, wide-eyed, not attempting to hide the shock in her voice.

He shrugs and smiles sadly. "Not when I'm with you."

She touches him them; wraps her fingers around his wrist and connects their grace the way they used to when she was human, except now she can see it. A streak of red emerges from the blue of her grace and flows into him, settling in the hole in his chest. Lucifer sighs in relief.

For a moment his grace seems healed, taking on its old frosty color, but when she removes her hand the grace jumps back into her and leaves him torn once more. She winces. "I'm sorry."

"Don't be. I knew it would be permanent." Kael nods, trying to push away guilt.

"Call off your demons, we're getting outta here."

Lucifer frowns. "This building is disused. There's no water supply."

"Yeah, well, you learn some science crap when you're human. Look." Kael splinters a crack across the ceiling above them. She twists the crack until it forms a broken square which promptly falls down on to a patch of holy fire, extinguishing it and giving them an exit. Plaster rains down around them.

Kael laughs at Lucifer's confused expression. "You can't have forgotten that a lack of oxygen puts out fire too?"

"Hmm. Must have slipped my mind."

Stepping nimbly out of the fire, Kael extends a hand to Luci. "Get the demons," she repeats. "We're leaving."


Kael had forgotten what flying was like.

Sure, she remembers being human and the disorientating experience of disappearing in one place and rematerializing in another, but when you're an angel, it's different.

You soar.

Kael's wings, now restored to their former glory, are spread out behind her as she dips and spins through time and space itself. Colors rush past her and there's a roar in her ears and it's wonderful.

She's powerful and strong and she hadn't realized how much she missed this.

Lucifer gets to the cabin first, but when he smirks at her and says "I won," she's so giddy with exhilaration and grace and Lucifer that she leaps for him, legs tangling around his waist and arms tightening around his neck.

"Easy," Lucifer chuckles, a little surprised, but she cuts him off with a short kiss. She presses her forehead to his and he wraps his arms around her as he lets out a quiet, "I missed you." Kael begins to murmur in agreement but he catches her lips with his own and they begin to move together slowly. It's strange, she thinks, that she knows from her time as human that Lucifer is cold to the touch, and yet as an angel she can't tell the difference between his body temperature and hers.

Then one of his hands is in her hair and the other fisting her shirt as the kiss turns open-mouthed and hungry. Heat builds and Kael tightens her legs around his waist as he slips his tongue between her lips. She moans a little when his hands slide down her back to firmly grasp her ass. She moves her hands down his back where she can pull up the hem of his shirt until most of his upper body is exposed, his arms preventing her from tugging the fabric off completely.

Lucifer breaks the kiss. "I haven't… did this. With a vessel." He clears his throat in a way that's oddly human.

Kael roams her hands over the planes of his chest, looking at him teasingly. "Are you trying to tell me you're a virgin, Luci?"

He raises an eyebrow. "You know I'm not." He lifts his arms so she can remove his shirt and undershirt, angelic strength keeping her small frame in position around his waist. His hands come down to grip her thighs this time.

Kael smiles as she peppers kisses along his neck, his shoulder, his chest. She breaks away long enough to say, "You could've fooled me. Don't worry, it's not hard," and brushes her fingers over a nipple. He lets out a soft moan.

She hears him say, a little disgruntledly, "But I am," and she laughs against his skin and lets him walk them over to the bed, his hands slipping under the back of her shirt as he does so. Feeling impatient, Kael tugs her own shirt over her head as he sits on the edge. Heat spikes in her stomach; now she's in his lap, she can tell Lucifer wasn't lying. She grinds against him a little and his eyes darken with lust as he swoops forward for another kiss.

Kael's so caught up in it all, the heat and the kissing and the muffled moans as their tongues slide together and her hands roam all over Lucifer, wanting to feel every inch of him, that she doesn't notice his fumbling. He pulls away with a questioning look as he slips his fingers under the clasp of her bra. "What in the hell is this?"

Kael chuckles as she reaches round to unclasp it. "It's a bra, Luci." She pulls it off and lets it fall unceremoniously to the floor.

His hands cup her breasts, fingers ghosting over nipples. He smirks when her breath catches. "Seems rather pointless. And annoying."

"Yeah, well," Kael huffs as she presses open-mouthed kisses along his jawline, "be glad you didn't get a female vessel."

"Oh, I don't know, you might be about to discover the advantages." He smirks, still teasing her breasts, until she drags her teeth lightly across his earlobe. "Kael." His erection strains through his jeans, becoming entirely obvious.

She grins. "You're right, we're entirely too clothed for this." In a blink, their remaining clothes are piled on the floor and Kael wraps her legs tighter around him, reveling in the feeling of skin against skin. Lucifer leans forward to kiss her neck, one hand still busy with her nipple, the other gripping her ass, and Kael moans and arches into it, her entire being set alight with need.

Bringing a hand up to her face, she licks a wide strip down her palm and reaches down to where Lucifer's cock is pressed between their bodies. Her fingers wrap around the base and she gives a single stroke. Lucifer bites down on her neck and groans into her flesh in a way that gives her shivers, and she starts to pump him slowly, twisting her hand a little when she gets to the head.

Then Lucifer's lips are on hers and she bites on his lip as he groans into her mouth, and his fingers are dancing along her inner thigh, teasing her. She speeds up the pace and he seems to sense the urgency because his fingers are slipping between slick folds and curling into her entrance while his thumb successfully locates and circles her clit. Kael moans with abandon, breaking the kiss. "Fuck, Luci," she says against his lips. "Where did you even learn to do that?"

Lucifer's wearing a sly smile when he answers. "I watch a lot of movies when I'm not planning the end of the world."

Kael is going to tease and ask, Oh yeah, what kind, but she's saved the trouble when his fingers inside her find that spot and she becomes a writhing, babbling mess in his lap. She strokes him faster and faster, smearing precome along his length, until they're both moaning and cursing and grinding against each other.

The need becomes too much too soon and Lucifer reluctantly removes his fingers from her and sucks them dry slowly. Kael gapes at him, because she's not entirely sure he knows how pornographic he's being, until he looks up at her and winks in a way that is so entirely Lucifer that she has to pull his stupid fingers out his mouth and kiss him until he's breathless.

She positions herself over him and sinks down slowly, letting him fill her, and they both hiss a little at the sensation. Then his hands are on her hips and they're both trying to thrust against each other at once, both trying to get more. Kael bites, sucks and kisses every inch of Lucifer she can reach and he moans into her hair as he reaches down to press a finger against her clit once more.

She moans deeply against his nipple as she's teasing it with her teeth and then her climax is ripping through her; stars bursting behind her eyelids. She clenches around him and she feels him release inside her as he cries out, pressing his forehead to her shoulder.

They come down together and he cups her face and kisses her softly and runs his thumb along her bottom lip and she smiles, because she's an angel again and she has Lucifer and she doesn't have to deal with any of Heaven's bullshit and she's just so content.

She cleans them up – angelic powers coming in handy – and Kael sees her sword lying on the nightstand. "I almost forgot," she grins, picking it up. The blue ring around the pommel glows brightly at her touch, illuminating the room, and she smiles fondly at it. "Yeah, I missed you too."

For once Lucifer doesn't have anywhere to be, so they're free and content to spend the night with each other, even if they don't need to sleep. They position themselves in bed; Lucifer on his back, Kael curled up against his chest. She smiles against him. "I'm pretty sure taking your virginity is some kind of sin."

Lucifer huffs a laugh. "It was worth it, at any rate." Kael smiles and slips her fingers between his, hands clasped over his chest.

"Why did you keep the wedding ring?" Kayla asks curiously. Angels don't normally keep possessions belonging to their vessels, save for their clothes.

"I didn't really think about it. I had a lot of respect for my vessel, I wasn't going to start throwing away things that were valuable to him when he was still, you know –" he gestures to his head "– inside."

"But he died."

"Yes." Lucifer stills for a moment. "I suppose it reminded me of you."


The next morning, Lucifer flies off without any warning, and reappears seconds later. "Michael has taken a vessel," he says grimly.

Kael's heart twists a little inside her. "Dean?"

"No. Another brother. He's bending the rules, but technically it still works."

"Luci –" Kael hesitates. "You – you don't have to do this."

Lucifer frowns at her, like she's said something entirely foreign. She tries again. "This – vengeance, it's been your goal for so long, in Hell too, but now you're out and we're here, and we could just stay, live ourselves, go wherever we want, you don't need to make this your sole reason to live, I just – you don't have to do this," she finishes lamely.

"I do."

"You'll die."

"Very likely."

Kael inhales sharply. "Then I'm coming with you."


It's Stull Cemetery, and it's noon.

Lucifer and Kael stand together when Michael appears. "Brother," he says, nodding in Luci's direction. His eyes flick to Kael. "I see you brought your whore."

Kael moves as if to step forward, but Lucifer raises his hand and she stops. "We were kin once, Michael," she says sadly. "You loved me the way you love Luci."

He glares at her. "That was before you twisted him with your blasphemous thoughts. Look at his grace! It's ugly, deformed, because of you." Lucifer looks down, ashamed, and Kael hates that he still cares what his big brother thinks after all this time. "You betrayed us all."

"Our Father betrayed us all, and those who stood with him became traitors to the rest of us," she retorts defiantly.

Lucifer raises his arms. "Enough," he says calmly. "Michael, this is ridiculous. Stand down and we can all go home. This battle doesn't need to be fought." Curious, Kael thinks, that he was so against the idea yesterday, and then the realization hits her – of course, Lucifer wants his brother back. Either he gets him or he dies. She tries very hard not to think about either option. "Why should we let our Father make us fight like dogs in a pit? For what? His own amusement?"

Michael remains unmoved. "Lucifer, you're a monster, and I have to kill you. I follow my orders."

Lucifer looks so plainly sad that it takes everything Kael has not to launch herself at Michael in his defense. She feels a spark of pride when she hears Lucifer's next words. "If that's the way it's gotta be, then I'd like to see you try."

All three of them tense, prepared for the inevitable battle.

A distant roar of an engine makes them stop, and turn towards the sound.

Kael frowns when she hears the opening bars of Def Leppard's Rock of Ages.

A black '67 Chevy Impala rolls to a stop in the battleground.

Sam and Dean Winchester step out of the car.

Fate can't be changed, after all.


A/N: Aaaaand we're done!

I hope you enjoyed it. Thanks everyone (again) for reviews and favorites/follows and such, I love all of you, *throws cookies*
I may write a sequel at some point, since Lucifer's gotta get out the cage at some point, right? (Well, I'm hoping so)

Fun Fact: According to this (and a few other sources) Kael is the name of an angel who fell with Lucifer, which worked really well since I'd already picked out Kayla as my OC's human name before I realized her angel name would have to be different. Coincidence?
