Chapter One

Call For Help

"Damn it!" Dean hissed as he watched the shifter he'd been hunting slip back into the dark recesses of the sewer.

Sam lowered his gun, sighing heavily. "Dean, there's nothing we can do." He huffed, patting a hand over his brother's shoulder. "It's gone, and there's no way we'll find it down there. We should wait until it makes another move."

The older hunter growled. "Oh, yeah, and let it kill someone else?" He gave his brother a questioning look. "You really think I can let him go like that?"

"I'm afraid you'll have to, Dean." The rustling of feathers cause both hunters to turn around and face their feathery friend.

"What the hell, Cas?" Dean walked closer to the angel. "You want me to let it go?"

Castiel shook his head. "No, I do not wish for the shifter to continue killing; but I have a far more important task from Heaven."

As Dean opened his mouth to make some smartass comment, Sam pushed his way just in front of him. "Well, what is it, Cas?"

The angel hesitated; shifting from foot to foot. "It's . . ." He shook his head. "It's the end of time."

"What- the apocalypse?" Sam asked. "I thought we stopped the end of the world."

"No," Castiel shook his head, holding up his hands in a visual display of the direness of the situation. "You don't understand. Not the end of the world . . ." He swallowed hard; a rare show of nervousness by the celestial being. "The end of everything."

"Doctor!" Amy called from the opposite side of the control unit. "What's going on? Where are we?"

"I'm not sure." The madman replied, leaning back against the railings almost nonchalantly as turbulence shook the TARDIS and everything inside it. "I don't have control over the TARDIS right now. It's like a tractor beam in one of those weird Earth movies has got it."

Amy stared at The Doctor for a moment. "Tractor beams?" She laughed at him. The Doctor grinned back.

"Right!" He pushed himself up off of the railings, and began to fiddle with the controls. "That's probably not it, so I'm going to try and set for a different-."

The Doctor was interrupted by a shrilly ringing alarm, ripping from somewhere in the mass of alien technology in the beloved Time-Space ship.

The bow-tied Time Lord glanced over at Amy. "Yeah, that's not good . . ." He attempted once more to change the TARDIS's course, and was met with sparks. "Well . . ." He turned towards Amy. "The TARDIS is taking us to Earth."

"What?" Amy asked. "Why Earth?"

The Doctor looked nervously between Amy and the monitor. "Because . . . Something terrible's about to happen, Amelia Pond."

The second that Sherlock had shown up, John had swung at him as hard as he could. Now Sherlock sat in one of the cushy chairs of John's flat, sporting a massive shiner, as the ex-army doctor yelled at him over and over.

"What the hell were you thinking, Sherlock!?" He shouted, face reddening. "You let all of us think you were dead for months! Do you have any idea what that did to us? Huh?"

"I-."

"No!" John spun around, arms crossed as he paced the room. "I don't want to hear excuses; I don't want to hear apologies! I want to hear one reason- one reason- why I shouldn't throw you out right now and continue living on my own."

Sherlock stayed quiet for a long time; thinking of the best way to word this. "I . . ." He put his face in his hands. "You won't throw me out, because you missed me. I saw you crying; at my headstone."

John's face nearly drained of color. "You . . . You were watching?"

"Of course!" Sherlock stood up, placing both hands on John's shoulders. "You're my friend, John. I had to make sure Moriatry's men did as they were told."

"Moriarty?"

"Yes, yes, he told me that if I didn't jump, he'd shoot you all- but that's beside the point!"

John threw his arms up. "B-Beside the point!? You were dead!"

Sherlock shrugged. "Well, not really." He sighed. "I thought Moriarty might do something like that, so I asked Molly to help me, and she did. So, see?" He poked his arm. "Not dead. Anyway, I had to keep watching from a distance, because I feared that coming back from the dead would result in you lot being shot."

The shorter of the two stared quietly at Sherlock for a long time. "So . . . Why did . . . Why did you come back. What happened to make you change your mind; to make you take a risk like that?"

For once in his life, Sherlock didn't want to reveal one of his discoveries. He avoided answering for as long as possible, until- finally- he had to tell his friend. "The end of all things, my friend, is on it's way."

"Okay, seriously, Cas." Dean huffed as the angel led them inside an old barn. "What the fuck is up with you? You aren't telling us anything!"

Sam shook his head, clapping a hand against his brother's arm. "Don't worry, man. It's not like Cas' leading us into some sort of trap, or anything. Stop freaking out."

"I am not freaking out!" The older hunter swatted his brother's head. "I'm just irritated! I don't like letting things get away."

"You should stop worrying about that monster, Dean." Castiel told him; not bothering to look back. "It isn't as important as this. I am sorry, but I need your help for this."

"What is it exactly you need our help for, Cas?" Sam asked calmly, crossing his arms loosely.

Castiel stiffened more than usual, turning to face them. He only looked at them for a short time before his eyes flickered towards one of the high windows. He swallowed heavily, looking back at the boys. "You should be able to see why in approximately thirty seconds."

"What the- Cas, come on!" Dean growled impatiently. "Stop tip-toeing and tell us what the fuck is going on already!"

Sam- who had been looking out the window until then- slapped at his brother's arm. "Dean." He pushed the older hunter a little. "Dean, look."

"Cut it out, Sam!" Dean barked at him, shoving him off. "What're you freakin' out over, Sammy?" As Dean turned to look out the window as well, he had the wind knocked out of him by Castiel, who threw them both to the ground.

The second Castiel did that; the entire left side of the barn erupted into wood splinters, and a sound so impossibly loud that it could rival the angel's true voice.

Dean tried to push himself back up, but he had been trapped under a wood beam. "Cas . . ." He groaned. "Cas!"

The angel pulled his attention away from the epicenter of the wreckage; eyes widening the second he saw the hunters- nearly being crushed under the smoldering wood. He moved over to them as quickly as he could manage and lifted the wood framings off of the two. "Dean, get Sam out of here." He motioned to the semi-conscious Winchester laying on the dusty barn floor.

Dean quickly did as the angel said; gripping his own stomach tightly as he dragged Sammy out of the burning barn. The second he felt they were far enough away, the eldest Winchester hit the dirt, still clutching his badly bruised stomach as Sam began to stir more. "S-Sammy?"

Sam pushed himself slowly off of the ground, hand reaching up to hold his pounding head. "God . . . I'm alright, Dean . . ." He eyed his brother carefully. "How 'bout you? Are you alright?"

The older hunter laughed. "Yeah, I'm dandy." His expression contorted into something more serious as he stood back up- staring into the flaming barn. "I'm a lot more worried about Cas. He seemed really . . ."

"Where is he?" Sam asked, looking around.

"Still in the barn."

"Wha- Should we go back?"

Dean shook his head. "Not you." He forced his younger brother to sit back down in the dirt. "You need to stay right here and put something on your head. Your bleeding." Without another word to the younger hunter, Dean sprinted back to the barn; taking a deep breath of fresh air before pushing his way inside the burning structure. Eyes clouded by smoke, the hunter had a hard time finding the angel they'd left behind. But walking straight forward for a few seconds did the trick just fine.

"Dean?" Castiel glanced at him. "What are you doing in here? I sent you outside to wait with Sam, and I meant for you to stay there."

The hunter huffed. "Come on, Cas. You look like you're gonna need help."

The angel sighed. Dean had him there. "Fine." He lifted his angel blade, pointing to the epicenter of the flames.

Dean simply stared for a moment before pulling his gun out, aiming focusedly on the strange object before him. As the flames died down, and the two could clearly make out what the object was, Dean threw his hands up. "You have got to be kidding me."

Even Castiel- oblivious angel of the Lord he was- found himself thrown a bit by the blue box that stood before them. "Dean, what is a Police Call Box, and is it dangerous?"

The Winchester shrugged. "That was awhile before my time." He admitted. "But I'm assuming it's a box where you can call the police from. Like an emergency phone booth, or something."

"Should we be fighting something?" The angel asked, growing more and more edgy by the second.

"I dunno." The hunter responded. "These things aren't supposed to be dangerous, but they aren't supposed to fly, either." He paused for a moment, thinking quietly. "Maybe I'll go take a look at i-."

"Aha!" Suddenly the doors on the box flew open, and a tall, skinny man stepped out. "Look, Amy! It is Earth!"

The hunter and angel exchanged confused glances.

"So it is, Doctor." A shorter red-head with a thick Scottish accent stepped out of the box behind him. "Good thing, too. I was getting a little homesick."

The two strangers laughed at the apparent joke, still not realizing that two armed and confused men stood behind them.

"Uh, excuse me." Dean called.

Amy and The Doctor spun around, both grinning at him. "Oh, hello!" The Doctor waved.

Dean rolled his eyes. "You both human?"

The Doctor poked at Amy. "She is; I'm not. Nope."

"That's right." Amy confirmed with a nod and a smile. "He's The Doctor."

"And she's Amy Pond."

Dean kept his gun trained on the bubbly man. "Alright, in that case, we won't hurt her. What the hell are you, if you're not human?"

"He's an alien." AMy answered for him smoothly. "Time Lord from the planet Gallifrey; last of his species. Pretty nice guy, if you give him a chance."

The Doctor's head tilted. "Why would you do that? Shoot us, I mean. Has something happened that I can help with?"

"You nearly killed my brother and I with that . . . Whatever the hell it is." Dean grumbled.

"Dean?" Castiel looked over at the hunter. "This man is not our enemy."

Dean nearly dropped his gun. "What?"

"He is not our enemy."

The hunter turned fully towards Cas, lowering his gun completely. "Are you kidding me? I thought you thought they were hostile just a second ago!"

"I did." Castiel nodded. "I may be a celestial being, Dean, but that doesn't mean I'm incapable of changing my mind."

"Guys!"

All eyes turned to the front of the barn where Sam was standing with two other people. "We have a problem."

"Okay, I'm sorry; Gallifrey?" Sam questioned, staring oddly at the madman who called himself The Doctor.

The Doctor nodded. "That's right! Born and raised there; sort of. It's kind of a long, weird, timey-wimey story."

Dean gave The Doctor the oddest look he had. "Timey-wimey? How the hell old are you?"

"Nine-hundred and some-odd years." The Doctor responded. "Now, I know a bit about you two- the brothers who hunt monsters. Even to a Time Lord, you are intriguing; though I've never cared much to meet you in person until now." He moved over to the newest arrivals who were standing near the angel. "I'm curious about you two." He pointed a finger at both Castiel and Sherlock.

"Sherlock Holmes." The handsome Brit with the impressive back-eye extended a gloved hand to shake. "I'm a consulting detective in London."

"Or, at least he was," The man standing next to him commented. "If he wasn't considered dead."

"I told you, John, Lestrade is fixing it for me now. It'll be like I never jumped; okay?"

John Watson huffed in a way only a true woman could.

"Suddenly," The Doctor said, tilting his head oddly, "I don't really want to know that much." He skipped a step to one side, smiling at Castiel. "And who are you? What's your life story?"

Dean popped his head in between the two. "Trust me, Doctor- you don't want to ask the 'life story' part. You'll be standing here 'til next month, and that isn't an exaggeration."

Castiel shrugged a bit. "That may be true. I have had a long life, Dean."

"Oh yeah?" The Doctor challenged, eyes bright. "Try me, Castiel."

The trenchcoat-clad man tilted his head, thinking. "I have forgotten exactly, but I'm sure it has been at least three thousand years since I was created."

The Doctor made and impressed whistle. "Yep, can't top that." He straightened out. "So, what are you? Something like me, or just a really, really, really old human?"

Castiel stared at The Doctor for a moment. "I am an angel of the Lord, Doctor."

The group fell silent for a moment while Dean and Sam sighed heavily. "That's impossible." John dismissed Castiel completely. "Angels don't exist."

"Oh, but extraterrestrials do, John?" Sherlock asked, motioning towards The Doctor. "I don't think it's that far-fetched at all."

John shook his head angrily at Sherlock. "Oh, so you pretend to die, and then you come back to me believing in angels and all that nonsense? Please! Your 'death' killed that belief for me."

Sherlock crossed his arms. "My 'death' is what made me believe John. You remembered what I told you on our way over, don't you? How can I not believe that?"

"Doctor." Amy grabbed at The Doctor's sleeve. Only then did the others realize that The Doctor had taken out a weapon. "Doctor, he doesn't look like one of them at all. I think he's okay."

The Doctor shook his head. "No, Amy. You can't ever trust the Angels. They'll always want nothing more than to kill you in the end."

"Kill you?" Dean laughed. "Man, put the thing down, Doctor. Cas wouldn't hurt an innocent man. He's harmless when it comes to humans."

"That isn't true, Dean." Castiel replied. "I could hurt a person if I felt the need to."

"Do you feel the need to?"

"No."

"Okay, then." Dean smiled. "We're good." He turned to face the Doctor, who was slowly lowering his weapon. "Why would you think that Cas would want to kill you and Amy, Doctor? What have the angels ever done to you?"

The Doctor shook his head. "I've never met a real angel before today." He glanced at Amy. "We're used to dealing with the Weeping Angels. Creatures that turn to stone whenever you look at them. But when you blink . . ."

"Th-They're fast." Amy whimpered. "Fast, and terrifying, and they'll kill you by dragging you back in time, and forcing you to die the day they took you."

"Well," Sam muttered. "Glad we never met any of those."

"No, Sammy, all we have to deal with are werewolves, vamps, vengeful spirits, djinn for example- those were fun."

"Don't be an ass, Dean." The younger hunter told his brother, punching his arm. "Don't you think that some people might not have been raised the same as us?"

Dean huffed. "So? That's no reason not to be able to listen to us talk about it-!"

"Enough!" Castiel- Angel of the Lord- commanded with an intensity that proved his title. "I need to explain to you why you were all gathered."

"Wait, so you brought us here?" Amy asked.

Castiel shook his head. "No. God did that."

"I don't believe in a God." The Doctor replied.

"Whether you do or not, I'm sure you care about this planet, and the well-being of those on it."

"What if we said we didn't?" The Doctor challenged hypothetically. "We could go anywhere, and not die along with the Earth."

Castiel tilted his head. "Well I'm sure that you've already come to understand his, Doctor, but it isn't just Earth. The end of all things is growing closer and closer."

Please don't hate me for this! I just wanted to try something new, and this popped into my head, and I was like; "WAH!"; and then I wrote it. : P
