Hi everyone! This is my first fanfic ever!

Ok so I've had this rather complex idea for Supernatural for about a year now and it has grown to the point where I had to just write it down! This will be mostly third-person POV, with Dean, Sam, Castiel, and Crowley playing big roles in this story. An OC will be introduced next chapter but I am still working on how to develop this particular OC.

Please review! Since this is my first fic, please no flames, but I do welcome helpful and critical reviews that can help the story. Also must add that this will begin from the middle of Season 9 (I thought it was a perfect place to start the story) but it is also an AU. No Wincest or Destiel or Dean/Crowley will be included (sorry to all you lovely shippers!); don't get me wrong I'm a shipper myself but it just didn't make it to my story.

Disclaimer: I do not own Supernatural (I WISH I did), but my OC is all my own.

Hope you all will enjoy it!

Sam walked into the bunker, returning from a quick run to the nearby grocery store as there was no bologna or beer left. His appetite had really grown since Cas had healed him of his last wounds and injuries. He and the quirky angel were still desperately trying to find Gadreel, all while trying to get back in touch with Dean. It had been just 2 weeks since their last argument after their close encounter with Abaddon. Sam was still pissed with Dean; the stupid crap he usually does always ends up with them working apart. 'Stubborn, pig-headed idiot.'

"Sam?"

The youngest Winchester was pulled from his thoughts at the sound of Castiel's voice. He looked down to see the angel standing by the table in the main room, looking up at him with a slightly concerned look.

"Yeah?"

"Is everything all right?" Cas asked as Sam began to walk down the stairs. "Yeah, I'm fine, just thinking." Before Cas could reply, he continued "Have you found anything that can help us get to Gadreel?" Cas shook his head in response before sitting down next to the numerous books laid across the end of the table. "No, the few spells I found are not strong enough to find him or Metatron for that matter."

With a sigh Sam took the seat across from the trench coat-clad angel. "There has to be something we can do to get to him." He began to tap his foot anxiously as many thoughts and possibilities ran through his head.

Cas was at a loss for words, knowing if he tried to say something encouraging to Sam it will backfire, as it usually does. Looking down at the pages in front of him, Cas decided to continue his research. Noticing Cas going back to the books Sam got up and headed to the kitchen to drop off the beer in the fridge and make himself a sandwich. 'Maybe two.' As he made himself his snack, his phone began to ring. He froze for a second – only Dean had that ringtone. Pulling his phone from his pocket in a flash he answered, "Dean?"

"Hey, you better have beer at the bunker, heading there in about 2 hours."

Sam's mouth hung open a bit; he shouldn't be shocked that his older brother would act as if nothing wrong happened or that they had left on a bad note. Rolling his eyes, he said "Yeah, bought two packs today."

"Perfect. We'll be there later."

"We? Who's with you?"

"Hello, Moose!"

'Oh, no.' Sam thought at the sound of Crowley's voice over the phone. "Don't tell me Crowley's riding shotgun with you?" Sam then turned to where Cas was, seeing him walking towards him. "Long story, I'll explain later."

"Wai-"

At that moment a loud and dreading alarm began to sound in the bunker. Jumping a bit, Sam and Cas looked around as a red light by an entryway began to blink. Looking at each other, Sam could vaguely hear Dean's voice yelling at him through the phone's earpiece.

"I'll call you back," he said, hanging up and heading toward the doorway, noticing the alarm getting louder. "What is that alarm?" Cas practically yelled, having to raise his voice over the alarm.

"I don't know!" Finding the source of the irritating sound at last, Sam stopped at the sight of what looked like something out of a James Bond movie. "But I don't think it's a good thing."

He and Cas looked at what seemed to be a radar; Sam realized then it was the same radar that Kevin had told him and Dean about when the angels fell. "I thought all the angels fell?"

Cas stared at the radar, seemingly unaware of what Sam had said. "Cas!" Sam yelled.

Cas looked up but not at Sam. "It's coming."

This did not sound good…

"Who? What? Cas, what's going on?" Castiel began to run out of the room, pulling on Sam's arm. "I'm not sure. But something is headed to the bunker, and it's close!"

Quickly switching into battle mode, Sam grabbed his rifle and followed Cas to the main entrance, noticing the angel pull out his blade from his coat. The alarm grew louder and erratic, indicating just how close whatever was coming was near. Suddenly, everything went quiet; the alarms went off and the red lights had stopped blinking.

Sam raised his rifle and Cas held his blade ready…

Knock knock knock.

Eyebrows furrowing, Sam looked over at Cas, unsure of what to do. Before either of them could make a move, three more knocks came.

Casting a quick nod to Sam, Castiel stepped forward to open the door; they braced themselves for what was waiting for them.

But nothing could quite have prepared them for what they found…
