AN: I can't really say how fast I can update, because it always depends on when I get the time to write. Thanks to all followers so far. If you like it, leave some feedback :) And now strap in for chapter 2.

Dean sat back in his chair, rubbing his hand over his face in frustration.

"Why can't we ever catch an easy break, Sammy?" He sounded exhausted. "I mean, this is virtually impossible!"

Sam chuckled, but there was no humor in it. "We don't do easy, remember? I mean, I know where to find most of the ingredients for the spell, but unicorn dust? Dude, unicorns aren't even real."

"Hmm," Dean grumbled.

"Hmm?" Sam looked at his brother. "That all you can say?"

"Look, Sam, unicorn dust is the least of my worries. Even if we'd find any, how are we going to get four blood related hunters in this bunker? I mean, angel time travel is out of business, so screw unicorn dust."

Sam pondered his brother's words quietly. "Any word on Cas or Lucifer yet?" Dean quickly denied with a shake of his head.

"Same goes for Amara." Dean got up and paced back and forth. "Still wish I knew why Cas did it, you know. I just don't get it."

***sn***

Castiel felt exhausted. Ever since he said Yes to his brother in the cage, Lucifer had shown him his superior strength. He was an archangel after all, whereas Castiel wasn't. The latter, however, remembered something he had come across in the library of the man of letters when he had helped the Winchesters digging through the lore on a case.

He repeated the Enochian enchantment over and over for weeks now, ever since he had allowed Lucifer in. If two angels shared a vessel, the enchantment would eventually, bit by bit, transfer the grace and its power to the angel casting the enchantment. The other angel wouldn't notice it until the last bit of grace had been transferred.

Castiel had been on it nonstop, and it had hurt to see what Lucifer did while he was in charge but at least the brothers knew he, Castiel, was still there and that his vessel was currently steered by Lucifer. Him being an archangel made the enchantment having to be repeated a lot more times than if it were a lower level angel and Castiel wondered how long it would take him to finish regaining power over his vessel.

But if he had learned only one thing from the brothers, it was never to give up. And he wouldn't give up. He would repeat those words over and over and over until finally, eventually, he would succeed and complete the transfer. Pushing the exhaustion aside, he continued.

"Maybe another angel would be willing to help us out with the time travel," Sam wondered out loud. "After all it is in their own interest to defeat Amara."

"Are you feeling alright, Sam? They're dicks. They would rather see the world burn than help us." Dean's tone left no doubt about what he thought of angels in general.

Sam put down the note pad with the scribbled down spell and the ingredient list and sighed.

"Humor me, Dean. If Cas was there to help us out, how would we go about this? We need to be six blood related hunters for the spell, unicorn dust, and the Colt. Which is..."

"...awol," Dean finished Sam's sentence. "I don't think in all the world you'd find that many living blood related hunters, so the only way would be time jumping to collect them all." Dean looked up, eyes wide. "That sounds so wrong."

"And even if Cas was there, we don't know how many time jumps he can do before having to recharge his grace." Sam sighed and impatiently tapped his fingers on the list. "Even if we solve one problem, we still have like five other ones on our hands."

"Winchester luck... or rather, curse, Sammy," Dean put on a fake grin. Then he froze abruptly, blinking his eyes.

"Dean?" Sam frowned. Dean held up his hand, obviously thinking. Then he looked straight at his brother, wriggling his fingers.

"Sammy, laptop. Now."

"What's up?" Sam replied, pushing the laptop towards his brother. Dean didn't reply but hacked away on the keyboard, scrutinizing the screen. Just when Sam was about to speak again, Dean sat back with a silly grin from ear to ear. "Now what?" a puzzled Sam wondered out loud.

"Baby brother, I just found us some unicorn dust," Dean explained, looking smug. He turned the laptop around and pushed it towards Sam.

"Dude, that's a devil's claw," Sam stated, bewildered. "And they're not even pretty plants."

"Aw, Sammy, I thought you knew your herbs," Dean teased.

"Herbs, Dean. Not plants in general. I'm not a florist."

"Could have fooled me," Dean muttered good naturedly. "Scroll down, princess, read and learn."

Sam sighed, exasperated, but did as he was told. After a few moments his eyes grew wide. "The devil's claw, also known as devil's horn, ram's horn or unicorn plant..." He looked up, finding Dean's big grin staring back at him. "So..?"

"So we need a pod of this plant, dry it out and mash it into powder. Dust... unicorn dust."

"Wow," Sam exhaled, leaning back. "That actually sounds easy."

"Exception proves the rule, Sammy."

"It's Sam, jerk."

Dean grinned again. "Bitch."

"By the way," Sam continued, also grinning. "How did you know it was a plant?"

"I was thinking of curses. There's usually plants or herbs involved with the cure... and I once heard Bobby mentioning unicorn dust, or devil's dust to another hunter. I was only a kid but the unicorn sort of stuck. Never really though about it like ever again, though. Something must have jarred the memory awake."

They were silent for a moment, the mention of Bobby sending each boy down a short trip down memory lane. Dean pressed his jaws together, shaking it off, then made eye contact with his brother.

"Which still leaves us to figure out the angel flight problem," Sam sighed.

A dark shadow fell across Dean's face. Thinking of Bobby was bad, but they had come to grips with his death. Cas was a different matter, however. Technically, he was still there. But he was locked away, with Lucifer taking over the steering wheel. Temporarily unavailable. Out of order. That's what Cas was.

Footsteps from the hallway roused both Winchesters and in a flash the brothers were brandishing their weapons, training them on the doorway arc.

The footsteps got closer and then Lucifer, wearing Cas' meatsuit, appeared in the arc. Without hesitation the brothers released a round each towards the devil, knowing full well that would only piss him off. But their bullets never found their mark, because Lucifer disappeared instantly, only to reappear behind the brothers, relieving them of their weapons.

Sam and Dean both took a step back, glaring at the fallen archangel. Their stance indicated they expected to be flung across the room or attacked in any other way Lucifer might think up, but he just stood there, an impassive expression on his face, looking so much like Cas.

Lucifer dropped the guns on the table behind him and turned towards the hunters again just in time to catch the puzzled expression floating across their faces. They exchanged a quick glance, conveying their apprehension to each other.

An eerie light, like from a lightning bolt, illuminated the archangel briefly, displaying for a split second the magnificent looking wings of the celestial being. They looked so different to the ones Dean once had seen Lucifer display. What was going on? Those wings looked like Castiel's, but on steroids. Confusion crossed Dean's eyes.

"Cas?" He inquired tentatively.

"Hello Dean."
