Spoilers for Season Four of Lucifer.
Takes place after Season Four of Lucifer and before/during the events of Twilight.
Few alterations have been made, with the events of Lucifer taking place a few years prior. Lucifer did not leave for Hell, deciding to stay with Chloe instead after her confession.
Angels, and by extension demons, have been made a bit more powerful to match pace with the vampires' strengths and speed. Angels also have a more divine presence that's noticeable.
In Christian lore, Ariel is the archangel of Nature, meant to protect it and the elements, and was originally supposed to punish humans for their acts against nature. This is only altered slightly.
PROLOGUE
"You don't need to leave LA, you know. There are plenty of hospitals here that would welcome an angel like you into their staff."
Ariel wishes he didn't have to be so literal with his words, but her brother has always been the 'honest' one. It's his greatest strength, his greatest weakness, and in most cases, his greatest annoying factor. He's never even tried to hide what they are, something a part of her admires while the other part thinks is stupid. He is not wrong when people won't necessarily believe them, or anyone, but she hardly thinks that people are worthy of the proof of divinity.
She stops packing one of her boxes with a sigh. She doesn't even much to pack, yet it seems to be taking forever for her to get anything done. Long fingers wrap around her luggage bag and tosses it to the ground, sitting promptly on the bed with tired, worn eyes. She glances to her brother; he waits patiently for her response, always clad to the nines. The lack of the presence of Amenadiel shouldn't surprise her, but there's a small pain in her chest nonetheless. Just because her relationship with her older brother isn't as strong, it doesn't mean she wouldn't like to say goodbye.
"I don't need to, Luci. I want to. This city reeks too much of pollution for my tastes and if I stay here too long, I'll want to hurt my patients at the hospital instead of help them."
There's a grievance to her words - a built up frustration and sadness that comes when you don't quite have enough trust in yourself. The tiredness, uneasiness that comes when there's such a drastic change in your life and when you have to face the unknown. The type of feeling you try to hide, whether it's by running away from it, pushing it away, or doing everything you can to 'solve it' without addressing the real problem, anything that will help ease the tension and give you a false sense of control.
Lucifer takes a seat on the bed beside her case, nodding along with her words. She doesn't look him in the eyes, she doesn't have to as a sense of understanding and familiarity pass between them. He may be the punisher for humans' evils, but she's the punisher for their crimes against nature - literally in this sense. He's always thrived in the cities, being around such fascinating people is thrilling to him. He can't even begin to understand what it would be like for her - someone who draws their energy from nature, someone who has lived eons in absolute solitude in the woods.
Cities have always made her sick - nature cut down and replaced with steel, smog, smoke. Humans trashing everything her father had made for them. She's stuck to the forests for eons for a good reason, someone has to protect them since these humans certainly don't care.
She takes a deep breath. She's the archangel of nature and beasts so like it or not, it's time for her to accept that humans are her father's creations too. Which means just like the forests she's protected and healed, humans need healing too now. She needs to help and protect these beasts, her time in LA has helped her understand that, but there's still a bitterness lingering in the depths of her heart.
"I'll call often, Luci," Ariel continues, softer, her voice losing some of its venom. She faces him evenly. "Despite everything, I still missed my little brother. If I knew you were on Earth, I would have come and tried to find you sooner."
Which is true. Lucifer has always been her favorite sibling, a kinship due to them both being punishers for their father. She's been on Earth for a long time now, coming to it the moment she realized the humans were destroying what she's meant to protect and guard. She's not sure how long her little brother's been hiding here too, but if she knew that he was on Earth, she would have seeked him out, said hello. After all, it's not as if she wanted to find him just because she sensed a new celestial around. She wasn't sure what she was expecting to find when she came here, but she certainly didn't expect it to be the result of Amenadiel of all angels.
She doesn't expect for Lucifer to say that he's missed her, but he does give a small smile in acknowledgement and gets off the bed to pat her shoulder. She grabs his wrist and pulls him in for a tight hug. Awkwardly and hesitantly, he gives her a few pats on her back.
"Alright enough of that," he pulls away and brushes off the dust from his shoulders, "I do expect you to ship some of those lovely drugs from the hospital to me, with you about to become some big shot doctor and all."
"She's not going to ship you drugs," Amenadiel's voice rings out.
Ariel's eyes widen at his appearance. Amenadiel stands in the doorway of the hotel suite, his eyes softened when his gaze meets his sister's. Linda isn't far behind him, carrying Charlie on her hip. The small four year old smiles brightly and waves at Ariel. Her eyes soften at the child and she waves back with a crooked grin.
"Not to mention she'd lose her doctoring license and no offense, but we need a real doctor around so I don't keep getting calls on how to treat life threatening wounds."
Linda breathes a sigh of relief and Ariel almost laughs at the remark, remembering how Linda was the one most excited about her successfully getting her medical license. She wouldn't put it past Lucifer to call a therapist on how to stitch up a wound. She doesn't even bother correcting Linda, or Lucifer, that she's not a doctor quite yet; a nurse, yes, but she still has a few years to go in schooling to become a full fledged doctor. She should do something to thank her brother for forging her papers sometime - an ID and social security isn't exactly something that comes up when you live in the Amazon.
"You'll have to tell me exactly why my brother was making those calls to you in the first place sometime," Ariel comments, relaxing against the bed frame, "It makes me wonder just how much trouble you all got up to before I found you."
"Another time, sister," Amenadiel takes a step forward, "We will tell you everything you missed."
Ariel's nose scrunches up, "That's what you keep saying and the longer you wait, the more I get worried if you'll actually survive once I leave. Honestly, Diela, how bad could it have been? I came in to find the first woman raising a bunch of demons up to get Luci to love her and a new angel baby. Nothing can possibly be worse than that."
A few looks get passed around the room and she finds herself feeling a bit out of the loop. She doesn't like the way that Amenadiel looks at Lucifer as if he's the cause for trouble and steps between them to break his glare. Lucifer sticks his tongue out at Amenadiel from behind her back as she glares at Amenadiel, challenging him. Amenadiel takes a step back and sighs, mildly raising his hands in warning.
"I didn't come here for us to argue, I came here to wish my sister goodbye and to tell her to be careful."
Ariel relaxes at the peace offering and gives a solid nod in acknowledgement of his farewell.
"I told Luci that I'll call him often," she continues, almost cautiously, "I hope that I can do the same with you, Diela."
Amenadiel's eyes light up, his face brightening at the offer. "Of course you can call me, Ariel, I hope that I haven't given you any reason to think you can't."
She rolls her eyes at the comment, mumbling under her breath before continuing a bit louder, "Well how else am I supposed to get updates on little Charlie? I can't disturb Linda if she's busy with a client."
Amenadiel's face shifts for a moment before he spots the humorous gleam in her eyes. Lucifer, however, simply gags, "Why would anyone want any updates on that child?"
Ariel nudges him, "Drop the act Luci, we all know that you love your nephew."
"I'll love him a lot more when he's old enough to join me at the club. Oh - are they even going to have clubs where you're going?"
Ariel crosses her arms against her chest, "I doubt it, it's a little place called Forks. A bit of a way from Seattle, surrounded by forests. I don't think they even have a big enough population to justify a club."
"Ugh how boring."
"Hopefully, it will be."
