"Well, Crowley, King of Hell is far less believable than demon," the Doctor said, staring into the blackness of Crowley's eyes.
His own eyes widened a little when he discovered something strange within them but the demon took no notice. The Doctor didn't flinch at the close proximity; he stood his ground and refused to be the first to move. His face held the age and anger of someone who's been around for hundreds of years; and so did Crowley's. The difference was one of their faces also held empathy. It seemed like a stalemate until a grin cracked across Crowley's face, causing him to seem sardonic rather than amused. A deep, growling chuckle emanated from the demon.
"I like you, Doctor," he said, unconsciously rubbing his eyes as they returned to normal. "This meatsuit's memories don't do you justice."
"Meatsuit?"
"The man that I'm wearing," Crowley clarified, stepping back from the Doctor and gesturing towards his body.
The Doctor stared at him, horrified, disgusted, and almost insulted. "His name is Canton."
"You say that as if I care, which is sweet, really. If I had wanted to know his name I could have. He means nothing to me; he just looks good on, like designer clothes."
"Demon is sounding more and more likely," the Doctor grimaced.
Crowley smirked and scanned the console room until his eyes found two people standing behind the Doctor that he hadn't noticed. He looked at them the way a person would look at an insect, curious and a little bit disgusted. Amy shifted into a defensive position under his stare and Rory froze, both well aware that their cover of insignificance had been blown.
"Are these your pets?" he asked the Doctor.
"They're my friends," he replied, offended.
Crowley stared at them until something clicked in his mind. "Yes, I know you. Well, he knows you. Amy and Rory Pond."
"How do you know what Canton knows?" Amy asked.
"So many questions," Crowley said, shoving his hands into his pockets and immediately pulling them back out when he felt that they were still soaking wet.
"They share a brain and a body," the Doctor answered. "This thing-"
"Demon," Crowley corrected.
"-Demon that's in control is like a parasite, living off of its human host."
"Essentially."
Crowley walked around the console, viewing but not touching. He was curious but certainly not stupid; he didn't know what any of the cranks, buttons, or levers did. The three travelers watched him warily. They knew he was strong but they weren't completely sure what he was capable of. They may have been on the Doctor's turf, but Crowley was the one in control. He was the unpredictable one. Crowley looked up at the stairs leading out of the control room with amused and curious eyes.
"Just how big is the inside of this thing?"
"Very big," the Doctor replied shortly, wanting the demon out of Canton and out of his TARDIS.
"Well," Crowley said, shifting his body towards the door, "As fun as this has been, I have important business to attend to."
He strode toward the TARDIS doors but the Doctor jumped into action and managed to make it there first. He threw himself in front of the doors, blocking Crowley's way while trying to pretend he wasn't intimidated. The amusement in Crowley's eyes died when he saw what he was trying to do. It was quickly replaced with a rage that could make a lion cower before him.
"What do you think you're doing, Doctor?" he growled.
"I can't let you leave. Not with Canton's body," the Doctor glared, his gangly limbs spread out to cover the doors as best as possible. It would've been a funny sight in any other situation.
"I'm not leaving any other way and I'm telling you now, I will be leaving. I don't have time for this childish crap," he hissed.
"What's the point of life if you can't be a little childish sometimes, eh?"
The Doctor laughed nervously, becoming more uncomfortable by the second. He wouldn't look the demon in the eye and kept glancing behind him. Crowley narrowed his eyes at the alien, his suspicion growing as fast as the Doctor's awkwardness. He started to turn around and the Doctor panicked.
"Um, er, maybe we could work something out!" he blurted, causing Crowley to pause.
"Just what are you try-"
A sickening crack echoed throughout the room as a metal, folding chair connected with the demon's skull. He retained consciousness long enough to realize what had happened but crumpled in a heap on the floor soon after. The Doctor sighed, dropping his arms as he slumped forward like he had just gotten through holding up a weight. Relief was strong in his features, but as he gazed up at Amy and Rory there was also mild irritation.
"It took you long enough," he complained.
"You try sneaking up on a demon with a chair!" Amy snapped.
Rory, who was still holding the chair, kept glancing from the man on the floor to the object in his hands. He looked a little sick as he set down the chair and backed away like he was trying to distance himself from what he'd done. He looked to Amy and they both looked down at Crowley. Canton. They weren't sure anymore.
"What are supposed to do with him, Doctor?" Rory asked. "We don't know who he'll wake up as."
"No, you're right. We'll have to restrain him to be safe," the Doctor said, not appearing very pleased about it. "Rory, set up that chair out of reach of the console. Amy, we're going to need a containment shell and some good ol' fashioned rope for back up. I'll stay here and watch him."
Amy ran off up the stairs while Rory carried the chair into a corner of the room. The Doctor beckoned Rory over and the two carried Canton, as they'd decided to refer to him, to the chair. They had trouble keeping him sitting up but it was made a lot easier when Amy flew back down the stairs with the rope. They restrained his arms, legs, and chest before setting up the containment shell. Once the circular base was connected around the chair the Doctor flicked a switch on the side and a transparent, glowing blue barrier shot up around Canton's unconscious body. The three shot looks at each other, knowing the only thing left they could do was wait.
And so they waited.
It wasn't long, fifteen minutes at the most, but it was long enough that the Doctor was growing fidgety and impatient. He sat in his chair, staring at Canton the way a small child would at homework. Thankfully for him, the excitement rushed back when he saw the unconscious man's head bob.
"HE MOVED!" the Doctor shouted, startling Amy and Rory out of their concentration.
They all kept their eyes on him and jumped when he moved again.
"Crowley?" the Doctor asked. He didn't react. "Canton?"
The man grunted at the use of the name.
"Canton, is that you?"
Canton moved, raising his head but finding it hard to keep it up. His head lolled for a few more seconds, body slumped forward, when consciousness hit him like a sledgehammer. His head jerked up, eyes wide, alert, and scared. They were darting around in a panic until they rested upon the bowtied Doctor. When he spoke, he spoke in an American accent and only said two words:
"The Winchesters."
