Back inside, Sam put down the duffel, pulling out one of the guns and some of the bullets, which he poured into a zip lock bag.
"OK," He called, motioning for Canton and the Doctor, who had been sitting on the other side of the console, talking, to come over.
"I suppose you got what you needed?" The Doctor asked.
"Yeah, but that's not all. If you're gonna help me with this, you both need to know what to do if a demon comes," Sam explained.
"These bullets—"he picked up one in his hand, holding it up to show The Doctor and Canton—"Are engraved with binding sigils. If you shoot one with this, they can't leave their meat suit, and they can't use their powers."
He stopped for a moment, seeing Canton's confused expression.
"Oh, yeah, right….So, uh, what I'm fighting are demons. They're basically really nasty spirits that went to Hell and became twisted and evil. Anyways, to take on physical form to do stuff, they possess a human body. But they're not trapped in it like your soul is in yours. They can leave if they want to, or you can exorcise them to send them back to Hell, although for now, that's not what you need to worry about."
"That's all very well, but how do I tell who is a demon?" Canton asked.
"Easy. First of all, they'll be coming at you, ready to fight. And they also have a tendency to try to scare people by showing their eyes—their eyes go black. Or red, but probably black. And under no circumstances make any sort of deal with them…if you do, they're just doing it to get your soul, because in ten years, more or less, they're going to come for their end of the bargain and you're going to Hell. It's not a good deal at all, trust me on that one."
"You mentioned they possess human bodies for their corporeal forms," The Doctor cut in.
"Yeah?" Sam replied, shrugging.
"You said to shoot them if they attack. Won't this leave their human host wounded or dead?" The Doctor asked, concerned.
"Well, yeah, but…if they're coming to kill you, you have to stop them first, before you can worry about the meat suit." Sam huffed. God, he thought. I don't have time for this...
"You know, I rather dislike that term," The Doctor said, his voice disapproving. "Surely there's another word for it, the humans they possess, because, after all, aren't they still human beings in there, past the demon?"
"Yeah, vessels, if you prefer. Anyways, the deal is, if they're coming for you, you don't have time to worry about them. You have to get away first. I mean, especially since you have Time Lord powers and…yknow. A Tardis? I mean, what would happen if they got their hands on this?" Sam
"The greater good, you mean," Canton nodded thoughtfully.
"Still, innocent humans—" The Doctor insisted.
"Who are trying to kill you?" Sam interrupted, impatience making him snappish.
"I was merely going to say, I find it distasteful, however I do understand where you're coming from, in terms of absolute necessity." The Doctor said, raising his hands as if to suppress Sam's rebuttal.
"OK. Good, so…you've at least go that much. If they come for you, shoot them. It will hold them in place in their vessels and render them temporarily powerless while the bullet's in, but they will try to get it out, because they aren't stupid. So it won't hold them for long. After you shoot them, you either need to exorcize them or get the hell out of there. Don't hang around waiting."
"Understood," Canton replied. "Speaking of exorcisms, how does that work, exactly?"
"Well, I could give you a copy of the text you'd read to do one, but I don't think you should worry about how to do that right now. If it comes down to it, shoot and run. Don't wait around...it's not worth it with the lower level demons." Sam explained.
Canton nodded. "Simple enough."
"Say, Canton, if you've done White House security, I'm guessing that means you know how to shoot?" Sam asked, holding out one of the guns.
"Yes, of course," He replied, taking it.
"OK, good. This is yours for now, and you'll need these—" Sam handed him the bag with the bullets. "There's only so many, though, so make them count."
"I understand," Canton replied, taking them too.
"Alright then," The Doctor said, "I suppose if you're ready, we can be on our way to finding your brother."
"Yeah," Sam nodded. "So...what will we need to do? Will I have to...y'know-" he motioned toward the chair with the psychic interface at the console.
"No, no, I don't think so. She now understands your brother's spacio-temporal signature. It is just a matter of following it, now that she's locked in. It shouldn't be difficult," The Doctor replied, moving to the console where he proceeded to type on a keyboard, studying the contents of the screens.
"Oh, OK, that sounds good," Sam said, sighing in relief. At least I don't have to go through that again, he thought.
"Oh," Sam said, turning to Canton, "Before I forget, here's a pair of cuffs with binding sigils. And...I'll give you a copy of the exorcism. But again, don't try to exorcize every demon you find. It takes time, and practice. Something you don't have. The cuffs, though, work on the same way as the bullets. As long as they're on, they can't use their powers, and they can't leave their hosts." He handed Canton the shackles, muttering to him "Just a minute, I'll have the exorcism too." He pulled out a notebook and pen from his backpack, which he placed on the edge of the console, and wrote down the exorcism, which he tore out and handed to Canton.
"Good. These might come in handy," Canton replied.
"Yeah. But I hope you don't need them. Anyways, Doctor? How's it coming with finding Dean's signature or whatever?"
"It's coming along well. I think we're nearly ready to depart," The Doctor said.
"Great. Well then, let's go for it," Sam replied, sitting down in one of the seats by the console, holding on to the armrests as the Doctor began the dematerialization sequence.
The screeching echoed, and the Tardis began to shake as they departed.
