They finished setting up the lights rather quickly, and jumped when they heard a pounding on the front door. Dean glanced at Sam, and then they both cast wary looks at the Doctor, who stopped what he was doing and looked up from his work. "Was that them?" Sam wondered quietly. The Doctor put his tongue to the roof of his mouth, keeping still to hear any more sounds. There was silence for a few more seconds, but it was broken by muffled voices and a scratching at the lock of the front door. Dean was about to step out of the circle of light, but the Doctor's arm flew up and across Dean's chest, preventing him from stepping outside the safety circle. "Don't!" the Doctor cried. Dean sighed, rolled his eyes, and backed away from the edge, skulking over to his brother and pouting. They heard muffled voices and the creak of the front door swinging open, and a group of people shuffling into the house. Suddenly, they quieted and a male voice broke through the silence. "What was that?" he asked. "Maybe a ghost?" a female voice suggested. Murmuring came from the group and could be heard getting louder and louder as they approached the living room. Finally, they were in sight and Sam, Dean, and two men in the small group of four sighed heavily with aggravation. All four disgruntled men muttered curses under their breath, until Dean was the first to speak. "What the hell are you doing here?" he demanded hotly. One man in particular looked especially peeved. "We should be asking you that!" he protested. Sam stepped forward, assuming an intimidating stance. "We are the professionals here, get it? Now get out, while you still can. This is more dangerous than anything you've ever faced-" the Doctor was interrupted by a snort of laughter coming from Dean. He glared back as Dean put a hand to his face and quietly chuckled to himself. "'Faced'... he said 'faced'... Ghostfacers..." he looked up, glancing at everyone and waiting for someone else to laugh. When met with only blank stares or disgruntled sighs, he returned to his usual serious demeanor and crossed his arms over his chest. "As I was saying..." the Doctor began again, with a pointed glare at Dean. "This is more dangerous than anything you've ever... had to deal with. This isn't ghosts." he said darkly. The two leaders of the small group glanced at each other, smirking. "If it isn't ghosts, then what could it possibly be?" they demanded. "Aliens."
"Aliens?" one man snorted. "'Aliens' aren't real." he insisted. The Doctor approached the man, though he stayed inside the safety circle. "You. What's your name?" he demanded. "Um... Harry. Harry Spangler. And this is Ed Zeddmore, along with Lucy Luxorm, and Tish Luxorm. Our team." he said, gesturing around to the members of his group. "Alright then, Harry, Ed, Lucy, Tish. If you don't think aliens are real, then leave. Just go. Now. While you still have a chance." the Doctor advised. Harry smirked. "No way, buddy. We're not leaving until we've cracked this case." he insisted. Sam and Dean looked at each other in dismay, before Sam approached the team. "I know we're not exactly allies, but you've got to listen to the Doctor here. He's right, this isn't like anything we've ever seen. When Dean and I arrived here, he was already in this room, scoping everything out. We didn't trust him one bit, but then he went outside, to get us some lights to put around the room. There's this... Police Public Call Box outside, you saw it when you came in, right?"
The group nodded. "It's a spaceship. I went inside, and it's... it's bigger on the inside! Larger, much larger, with separate rooms and everything!" Sam exclaimed, throwing his arms out for more effect. Dean snorted. "C'mon Sammy. Even I don't believe that." he protested, crossing his arms. The Doctor looked over his shoulder at the man. "No, he's telling the truth. I do have a spaceship that's bigger on the inside, called a TARDIS. Well, actually it stands for Time And Relative Dimensions In Space. Means it can travel in time as well as space." the Doctor rattled on. Everyone else in the room glared at him hotly, a sign that he should stop. Zeddmore tried to enter the circle, but the Doctor quickly stopped him. "Stop! Stop, don't even step foot in this room! The aliens, they're called the Vashta Nerada, and they'll strip you to the bone in under a second. You've got to trust me." he said hurriedly. A woman, Harry had introduced her as Lucy Luxorm, tentatively stepped forward. "How do we know you're telling the truth?" she asked quietly, training her camera, which was on and had been taping the entire conversation, on the Doctor. He whirled around and tore another leg off of the turkey Sam and Dean had pulled out of the fridge. Turning on his heel and carefully studying the shadows. When he found the right one, he tossed the leg inside, and it was clean to the bone before it even touched the ground. Lucy and Tish gasped in horror, and even Ed, along with Harry, paled a bit. "Well... that can't be an alien, I'm sure some supernatural beings can do that. Right?" Harry stuttered, glancing at the Winchesters. They shook their heads and the Ghostfacers faltered.
The Doctor situated the lights in such a way as to form a pathway for the Ghostfacers to enter the safety circle, quickly sealing it behind them. "So. Aliens." Tish said quietly. She looked as if she was in a trance, but quickly snapped out of it and extended her hand to the Winchesters and the Doctor. "Sorry, I'm Tish. My sister and I just joined the team, so we're quite amateurs. You Winchesters have taught the Ghostfacers practically everything we know, so thanks... i guess." she shrugged, setting up base. Lucy went around to everyone in the room with her camera, asking varying questions. She finally reached the Doctor, and her curiosity seemed to heighten. "Who are you?" she asked. He looked at the camera and made a face. "Is that thing really necessary?" he whined. At her nod, the Doctor sighed. "Oh well. I'm the Doctor."
"Doctor who?"
"Just the Doctor, mind you."
"And what do you do, Doctor? Are you a Hunter? A... alien Hunter?"
"Of a sort. But I don't do killing. Well, when I say 'I don't do killing', I mean I don't particularly enjoy it. Sometimes it's necessary. Oh I really hate admitting that."
"So... aliens are real?"
"Of course they are. Real as you and me standing here. D'you happen to remember, a few years ago when millions of people in America died because they turned into piles of fat? And then the fat started walking around and floating into these great heaping flying saucers?"
"Sure, I remember. Happened on my birthday."
"What did you think that was?"
"I dunno... I guess I didn't think it was really anything. Maybe some really big prank or something?"
"Aliens."
"How many aliens have you come across?"
"Thousands. Millions, maybe. Hard to tell, I don't really keep track anymore."
"Are you an alien?" Lucy questioned, her voice barely over a whisper. The Doctor looked at her, then at the camera, and finally back down at the sonic screwdriver in his hands. Out of the corner of his eye, he spotted Sam and Dean undoing their helmets, and he sprinted to them, exclaiming loudly. "What're you doing! Put those back on, right now!" he demanded angrily. They immediately replaced their helmets, their eyes wide. "We were just getting a little stuffy." Sam protested. The Doctor stared him down with fire in his eyes. "I don't care. Would you rather be a bit stuffy or die a horrible death?" he interrogated harshly. Without another word, Sam and Dean skulked off, moaning about how there wasn't anything else to do. "They're right, Doctor. It doesn't seem as if we can do anything else." Harry objected. The Doctor nodded. "That may be true, but I have to find a way of getting the Vashta Nerada out of here. This home will be sold again, and they're already here. Family after family will die, until you humans get it through your thick heads that there's something wrong with this house. Eventually it'll either be taken down or abandoned, but either way more and more people will die. The Vashta Nerada don't stop. They never stop." he said, causing chills to run down everyone's spines. Ed finished setting up a surveillance computer and looked at the Doctor quizzically. "Well, they die, don't they? I mean, everything dies, after a while." he insisted. The Doctor turned his old eyes to the man, and he backed away an inch or two. "They die, but, like humans, they repopulate."
"How fast? Cockroach fast?"
"Humans, cockroaches, same thing! Same birth rate. Mind you, humans sometimes act like cockroaches. The human race. God, you're thick."
Dean's brow furrowed in anger, but with a gentle hand on his shoulder from Sam, he calmed down enough to speak to the Doctor. "Alright, so what you're saying is we can't kill these bastards, but somehow we have to get them to move out. Let's start from the beginning then. How'd they get here?" he wondered. The Doctor pointed his sonic screwdriver at him, causing Dean to duck out of the way. "Hey! Watch where you point that thing!" he exclaimed harshly. The Doctor looked at the sonic screwdriver and made a face. "Oh, come off it! This thing is far from dangerous! In fact, the most dangerous thing it can do is... sometimes it blows things up. But that's not on purpose! Trust me, I would prefer it not happen. Still working out the kinks." he ranted, flicking the screwdriver on and off again. "Anyway, brilliant question. Fantastic! Molto bene! How did the Vashta Nerada get here? They hatch from forests, from trees, their trees, not just any trees..." the Doctor mumbled to himself. "Last time they weren't in their natural habitat was in the Library. They said the books were their trees... books... trees... BOOKS!" he screamed, flinging a finger of realization in the air. "Books! Books are the answer! Go around the room, look for any books you can find, bring them to me, but be careful!" he instructed everyone. The Doctor pushed all the Ghostblasters' equipment haphazardly to one side of the table, clearing space for the books. "And don't let your shadows cross! Ghostblasters, I'm sorry, but I don't have any suits for you. I'll let one of you have mine, but Sam and Dean have to make that decision on their own." he said as he unzipped his white spacesuit. Sam and Dean froze, glancing at each other, but continued searching for books as the Doctor slipped out of his suit and handed it to Tish. "Put this on." he instructed her. She set down the equipment and did as he instructed while the others brought back the books. "Alright. One or more of these books are alien. Paper made from alien trees, so they're alien books. Make sense?"
All nodded.
"Good. Now, look through these books and find anything unusual. Once you find something, tell me immediately. ASAP. Got it?"
Again, everyone nodded.
"Brilliant. Allons-y; get to work." the Doctor grinned as he slipped on his glasses.
