The Tardis sputtered a bit as they landed, as if to shake off the sense of urgency that was building inside the console room.
"Alright," The Doctor called as he stepped back from the controls.
"Where are we," Sam asked, standing from where he'd been sitting for the short ride.
The Doctor nodded, pulling up the feed of the outside on a screen.
"Ah, we're in Rock Springs, Wyoming, a bit into the future, by a day or so. It's midmorning out there."
"Okay," Sam muttered. "But you're sure he's here?"
The Doctor typed on a keyboard before replying. "Yes. I'm certain. His spacio-temporal signature is strong in this area. However, I'm afraid she can't track him down to the spot unless you want to land directly on him, so…you'll have to do the rest of that on foot."
"Yeah…no. I somehow doubt squashing Dean would help things any," Sam sighed. "I guess I'll be off then—" Sam nodded to the Doctor, heading for the door, when Canton approached him.
"Hey, wait. I was thinking, what with how dangerous these beings, demons, are, you might should have some help," he explained.
"No, really, I have to do this—" Sam began but was interrupted.
"Hear me out. You've gone to great trouble to explain just how risky an endeavor this is. But think, what if something happens to you? Your brother needs you, yeah? And who would there be if not for you?" Canton asked, putting the gun Sam had given him in a holster at his hip.
"Yeah.." Sam said thoughtfully. "I guess you're right. I just…I can't let you get killed doing this." He shook his head.
"I've fought the Silence, Sam," Canton said. "I can handle myself in high pressure situations. You said to shoot them on sight, and that's what I'll do. They won't have the chance to do anything."
"Alright then. I…I guess you can come. Doctor, though, you'll stay here?" Sam replied, gesturing to the Doctor, who nodded.
"Yes. However, I think I might have something of use to you," The Doctor said. He reached into a drawer in the console, pulling out a large, strange device.
"And…what exactly is that?" Sam asked, making a face.
"It's a psychic implantable communicator," The Doctor replied.
"Oh, OK," Sam said.
"Your hand?" He asked, prompting Sam to extend his hand to the Doctor, punching a button on the device, which sent a sharp pain stabbing through Sam's hand as the device pierced his skin.
He winced, muttering, as the Doctor let go of his hand, the device implanted. "You could have mentioned it was going to involve stabbing me."
"I thought the words 'implantable communicator' would suffice," The Doctor shrugged, giving a wry smile.
Sam chuckled. "Maybe," he replied.
"Eh, whatever," Canton rejoined, stepping up to get his implant.
"Bloody, that does sting a bit," Canton complained, waving his hand as if to dull the pain.
The Doctor didn't respond, instead implanting one in his own hand.
"Yes, so," The Doctor said, flexing his hand with the implant. "Try it out."
He lifted his hand toward his mouth, and spoke something nearly unintelligible into it.
Sam started as he heard the Doctor's voice inside his mind, saying:
"I think you'll find it quite handy."
"Yeah," Sam replied into his communicator.
"Yes, quite interesting," Canton told him through it.
"OK, that's kind of weird," Sam said, this time openly.
"Weird? I thought it was brilliant!" The Doctor burst out. "They will allow us to communicate with no interference except in extraordinary circumstance, most notably, they will work to communicate from inside to outside the Tardis. "
"Alright then," Sam said. "That's great. So….what, you'll stay behind and fly behind us, while Canton and I try to tail Dean?"
"Yes. And you'll be able to contact me immediately if something goes wrong." The Doctor nodded, making a shooing motion with his hand. "So, go on then! Find your brother!"
Sam nodded as he and Canton made their way out the door.
