Author's Note:

So very sorry it took so long! I lost Internet nearly a week ago so I wasn't able to post this :'( *begs for forgiveness* Finally, here comes the plot! :D Warning for lots of song lyrics! Also, Nico Gallagher belongs to Reaper's Curse :-)

P.S. The Nate scene is by our dearest beloved Kim! XD

*One Week Later*

Loki was still nowhere to be found. Isadora had told her parents about the demon, and now they had to consider that it had come for her just like demons had come for Loki. Gabriel could smell demon all over his son's room, but the trail dropped off at the window. He had tried reaching Loki telepathically, he'd called Crowley to see if any of his former demon alliances knew anything, and anything else he could think of, but nothing worked. Loki Winchester had been missing for a full seven days…gone without a trace.

Currently Isadora was over at the Gallaghers' asking if they'd heard anything, but even when they told her no just as always (she was over there twice a day, every day, she wanted to come in person instead of just calling), they offered for her to stay. Feeling uncharacteristically defeated, she accepted thankfully and curled up in the armchair, staring out the window. Leslie was in the kitchen making dinner, and Andy kept trying to throw a dash of marijuana into the spices for the fried chicken. Just another day in the Gallagher household.

"Izzy?"

She looked up to see Nico, one of the Gallagher brothers, standing next to the armchair with a cup of hot chocolate. "Hey Nico."

"Here, looks like you could use this," he said, extending the mug.

She took it and smiled gratefully. "Thanks."

They hadn't really spoken much; they knew each other of course, as their families were very close, but she hadn't spent nearly as much time with the Gallaghers as her brother had. Nico had always seemed nice, if not a little closed off. The whole family gave off that air of someone that had a deep, painful secret. It was downright depressing sometimes. She knew what it felt like to be in a dark place, she was in one presently. But there was just something in their eyes that was saddening even to her, who didn't admit to caring for anyone unless it was absolutely necessary. She lived by her Uncle Dean's mantra: No chick flick moments.

"Sorry about your brother," Nico said.

"Me too," she whispered, taking a sip of hot chocolate and closing her eyes as the warm liquid slid down her throat. "But it's not over yet. We will find him."

"Wish there was something I could do to help," he sighed, dropping down onto the couch.

"We're twins and half angels, I should be able to track him, but whoever the fuck has him must have the place loaded down with anti-angel sigils, because every time I try to reach him telepathically it's like I'm running into a wall," she growled, frustrated.

"You'll find a way to bring him back," Nico said firmly, as if the fact was set in stone and there was nothing that could be done to change it. "You're Isadora Winchester, for fuck's sake."

She smiled over at him. Surprisingly enough, those words helped.

"You show the lights that stop me turn to stone

You shine it when I'm alone

And so I tell myself that I'll be strong

And dreaming when they're gone."

"Would everyone please stop fussing over me? I am fine and dandy!" Kerberosel protested as Lucifer bitched at him to lay back down.

Lucifer ignored him and pushed Kerberosel over a little to make room, stretching out on the bed next to his friend. "You fainted, man. You're about as 'fine and dandy' as I was when my hound stepped on my Avenge Sevenfold CD and broke it. Damn dog."

"Oh please, you love that dog."

"Not when it's breaking my CDs!"

Kerberosel laughed and turned on his side to face Lucifer, his blond curls falling into his eyes. "You can stop coming over every day to keep an eye on me, you know. I'm not going to drop dead."

"Wouldn't that be the day," Lucifer joked.

"Please, you'd crash and burn without me to keep your ass straight."

"How is spending most of my time with a slightly flamboyant gay Brit helping keep me straight?"

Kerberosel groaned and swatted Lucifer with a throw pillow. "Not that kind of straight, you fur brained fool!"

They played around and teased each other, had been since Loki went missing, but underneath it was the mutual worry and fear for their friend. Kerberosel hadn't had a single feeling or vision since the time he'd fainted, and Lucifer just hated feeling powerless to come to his friend's aid. Everyone was looking high and low for Loki, using every tracking spell in the book as well as looking physically, but it was like whoever had him had sealed him off somewhere unreachable. Word had also gotten out that a demon had tried to threaten Isadora, but getting information out of him was pretty damn out of the question since he was dead. Apparently the girl had never heard of exorcism.

"Do you think Loki's okay?" Kerberosel asked softly. Both of their thoughts had gone to their missing friend by this point.

Lucifer pushed a stray curl out of Kerberosel's eyes. "I think we're not going to stop until we have him back here, safe and sound, as annoying and Sam-like as ever."

Reassured by those words, Kerberosel eventually fell asleep against his friend, but Lucifer laid there awake…wondering how much of what he'd said was actually true.

"Somewhere in this darkness there's a light that I can't find

Or maybe it's too far away, yeah

Or maybe I'm just blind."

Nate wasn't really one to stick out in his family; he was a bit cheeky, a bit adventurous, but when you have a sister like Izzy it's easy to be classified as normal. When Loki went missing it was unbelievable not mention unreal, I mean even though they knew they were exposed like everyone else, they didn't expect it to happen to their family. His parents had been going steadily worse with worry as each day passed with no sign of Loki turning up.

They also couldn't both search at the same time since they panicked that one of their other children would be taken as well. Sam would search at night whilst Gabriel kept them protected, then he'd vanish in the day going to every place and more he could think of, going from location to location in no more than an instant, searching high and low for their missing fledgling.

Nate wanted to help desperately since Loki was his big brother but he wasn't sure if his parents could handle the stress. Especially since the fifth night of Loki's abduction…he'd gone upstairs to ask if they found him, then heard quiet murmuring. Curiosity eating him alive, he crept towards Loki's room, listening quietly to see if he could hear anything that might give him some idea of how to help.

"You've been at it all day, you have to rest Gabe."

"But Sam the longer it takes the worse things could happen!"

"I know that but if you drain yourself too much you won't be much good to help him will you?."

Nate was startled to here a choked sob. "I should have found him already…he's my baby, Sam."

Nate risked a peek and saw something Isadora swore would never happen. Their loving - if somewhat eccentric - mother (well technically father, but Izzy was right, he gave birth to them so technically he was their mom) was sobbing into Sam's shoulder while their weary dad rubbed his back, soothing him the best he could. Taking a quick glance Nate noticed Gabriel was clutching a tatty stuffed purple bunny that he recognized as Loki's baby toy that Izzy had always teased him about mercilessly. He left before they noticed him, walking back to his room and losing himself in thought. He could talk to Izzy but she was equally stressed without her twin around.

Nate punched the wall in frustration. Why was he so helpless?

"I am a question to the world

Not an answer to be heard

Or a moment that's held in your arms

And what do you think you'd ever say

I won't listen anyway

And I'll never be what you want me to be."

On into the night, James was laying on the couch, his father asleep in the armchair where he'd been watching TV. He kept muttering "Cas" in his sleep, and his sleeping expression was so twisted and pained every time he said it that James had to go upstairs into his room just to escape it. He threw himself onto the bed and sighed. Loki was a close friend…more than a friend. He was like a brother. Him and James had grown up together just like everyone else in their "extended" family. Having Loki gone was like missing the final piece to a puzzle. That gap would always be there; taunting you, reminding you that no matter how dauntingly close you were to success, it would never be over until you had that final piece.

If only I could go back and fix everything, James thought. He remembered hearing Castiel talk of time travel, how he'd taken Dean back more than once. His father had added that it was exhausting, but not impossible. Then…something occurred to James. If an angel could do it, then couldn't a half angel? If he could go back and save Loki…then he could go even further back and save Castiel. I could have my other dad back, whispered the last remnants of his childish naivety. But if he could pull it off…Dean would have his husband back, Mary would be able to know her angelic father, Loki could be saved, and James could be reunited with the dad he'd been pining for since that awful night twelve years ago.

James picked up his phone, dialing Isadora. "Izzy? Hey, it's James. I have an idea…"

"Where did I go wrong, I lost a friend

Somewhere along in the bitterness and

I would have stayed up with you all night

Had I known how to save a life."

~How To Save a Life by The Fray

"I think he's ready," Eva drawled. "Release him."

The demons flanking Loki's chair started undoing his restraints, the young man's glazed eyes raising as he gained his freedom. His body moved like that of a robot as he rose, rolling his shoulders and stretching his newly strengthened limbs. His eyes were the same color, but they now held a certain darkness…an emptiness where his humanity had once been. He was so full of demon blood that the human DNA had been everything short of overwritten.

Eva smiled and stroked his hair. "My perfect warrior."

Loki clenched his hands, eager to use this new, dark power swelling inside of him.

"Fear not, love, I have a mission for you," Eva whispered, leaning up to his ear. "Kill every. Single. Winchester."

Everything that made Loki who he was had been blotted out by demon blood…so he hastened to obey.

"Why won't somebody come and save me from this, make it end?

I feel it deep within, it's just beneath the skin

I must confess that I feel like a monster

I hate what I've become, the dark has just begun

I must confess that I feel like a monster."

~Monster by Skillet

"Time travel?" Lucifer repeated.

Isadora narrowed her eyes. "You really think you can pull it off?"

"I'm half angel, I might be able to help…" added Kerberosel.

"I know I can do this," James said firmly.

The group sat around in Isadora's bedroom, discussing the master plan that James had formed. He intended to go back and find a way to save Cas and Loki, and he wanted to know who was going with him. Isadora, Lucifer, and Kerberosel were all a tiny bit skeptical, but they didn't hesitate in the slightest when he asked them to go with him. James looked around at his friends. Isadora stood with her arms crossed and her head held high, Lucifer was leaning against the wall with a look of pure determination, and even small, delicate little Kerberosel looked ready to jump into it headlong, tiny sparks flicking from his fingers in response to his excitement. His powers always flared up in reaction to his moods, a side effect of having such strange genes.

"Calm down before you fry Izzy's bedroom," Lucifer said dryly, placing his hand over Kerberosel's.

The sparks gradually died down, and James continued. "I don't know how long it will take, and I can't tell you it won't be dangerous. We'll have to leave notes for our parents, but we can't directly tell them we're leaving, they'll find a way to stop us. Is everyone still on board with this?"

"You couldn't stop me if you tried," Isadora said fiercely.

"Me and the bitch are in," said Lucifer.

Kerberosel nodded. "What he said."

And so began the journey of four friends. They wrote notes to their families, armed themselves to the teeth, went over the plan, and finally met back in Isadora's room three days later. One note lay on Aziraphale's piano from Kerberosel, there was a note in Gabriel's cookie jar from Isadora, a note from Lucifer was tucked under Leslie's favorite beanie where she would no doubt find it, and a letter from James was on top of Mary's diary (she would relay it to Dean, James was certain). All of them had different wording and different messages, but they got the point across nonetheless: they were leaving to save Cas and Loki and they didn't know when they'd be back, but they promised to stay safe. And the words "I love you" were somewhere in each of the notes.

"Are you ready?" James asked after they'd all distributed their farewells.

Isadora held up her automatic rifle loaded with rock salt. "Oh yeah."

"Let's kick some demon ass," Lucifer grinned, a revolver tucked into his belt and a large vial of holy water tucked into the inside of his jacket.

Kerberosel brandished his blade, which resembled an angel sword but had an ebony hilt that came from its demon origins. "Ready as I'll ever be."

James nodded, the group clasping hands for the time travel. Time to find out what I look like as a four year old.

"I step out of the ordinary

I can feel my soul ascending

I'm on my way, can't stop me now."
