Abandoned barn

Sam, Dean, Cas, and the Doctor were all standing back to back as demons approached them. Dean and Cas were each holding angel blades, Sam had his demon knife and the Doctor had his hands stuffed in his pockets. They weren't as outnumbered as they were before but they were still outnumbered.

"Does anyone have a plan?" The Doctor asked. All of the anger he was radiating earlier was suddenly gone.

"Kill as many demons as we can," replied Dean.

"That's not a very good plan," Cas said, "They have a significant upper hand."

The Doctor's brain was whirring, trying to come up with any sort of plan that would get all four of them out of the barn alive. The front doors were blocked by demons so running out that way was not an option. There was a whole ton of alien tech lying around, maybe he could use some of that. He never figured out the Lapljis plan with the demons so he didn't know how to stop the demons.

The demons were now throwing punches, Sam, Dean, and Cas were punching back and going in for the kill while the Doctor was just blocking and dodging. Dean had been the first one to stab a demon but there was a little reprieve. Sam was still weak from earlier and was barely holding his own.

"Did the demons say anything as to what they were doing?" The Doctor asked between blows, trying to figure out a plan. He knew he wouldn't last much longer and he was out of practice and getting tired.

Cas pulled his angel blade out of a demon then said, "Allowing demons to possess someone without the smell of sulphur."

That got the Doctor's brain connecting some dots, "Cover me!" he shouted as he ran towards a control panel taking out his sonic screwdriver. Dean had killed another Demon and ran behind the Doctor while Sam and Cas slowly followed. Sam wasn't doing too well, he was struggling to hold his own and nobody was able to help him. The Doctor had to work quickly. He tore the cover off of the control panel and started pulling out wires and doing some sonic-ing with his screwdriver.

"How exactly is that gonna help us doc?" Dean asked after killing another demon. They were significantly outnumbered and fatigue was starting to set in.

"If the demons possessed their hosts using Laplji technology then I can create a pulse to force them out," The Doctor said as fast as he could.

Someone must have heard the Doctor's explanation as to what the Doctor was trying to do because Dean was sent flying, losing his angel blade in the process.

"Hurry!" Dean shouted as he got into some hand-to-hand combat with some demons.

The Demon that was fighting Sam took his knife and threw him to the ground. Sam was now struggling to see straight, unconsciousness trying to consume him. Cas finished with the demon he was fighting, then tackled the one that was about to finish Sam. Sam took a little pause to right himself, and to try and find his weapon. He snatched his knife up pretty quickly and was walking backwards towards the Doctor, trying to put as much space between himself and the oncoming demons.

"Almost got it!" The Doctor shouted, with his arms stuck deep in the control panel. All of a sudden he was sent flying across the room, dropping his sonic screwdriver. Everyone was so consumed with staying alive nobody noticed Krammeyer sneaking up on the Doctor.

"You will not stop us, Doctor," Krammeyer said as the Doctor was getting up off the floor.

"That hurt!" The Doctor shouted rubbing the back of his head, "You shouldn't throw people across the room! It's rude!"

"I don't care," Krammeyer said as he pushed the Doctor up against a post with just a flick of his hand. The noise caused Dean to turn around and attack Krammeyer, but before he could get close enough Krammeyer had flung him against a different pole.

"Now you Winchesters never do give up. After everything you just learned about the Doctor you still want to trust him?"

"Well, it's better than siding with you," Dean retorted. Other demons had begun to watch what was going on in front of them, trying to figure out which one to kill first.

Dean had been providing the Doctor with some time to figure out how to complete his plan. There was no way he could break the demon's hold and the control panel was on the other side of the room. He had dropped his sonic, so no remote activation. Dean couldn't help him, he was in the same predicament. Cas was fighting a losing battle with another two demons. That only left the Doctor with Sam... where was Sam? The Doctor frantically looked around trying to find where the younger Winchester was.

"If you're going to kill me just get it over with," Dean said keeping Krammeyer's attention on him hoping that Sam would be able to do something.

Cas had just killed another two demons and some of the demons advancing on Sam turned to deal with Cas so he wouldn't be able to help Dean and the Doctor. Sam was left with only one demon on him as others had stopped to watch Krammeyer.

"Why would I make it quick?" Krammeyer said walking towards Dean, "It's no fun that way." Now Dean was starting to get nervous but he did his best not to show it.

The Doctor had finally spotted Sam, who was in the middle of finishing off another demon. Sam had gotten very lucky, the demon he was fighting was pretty inexperienced so he was able to get the upper hand and kill it. Sam looked over at Krammeyer for the first time in a while and saw Dean up against a post with Krammeyer advancing. Just as he was about to storm down there to save Dean he locked eyes with the Doctor who shook his head. Sam stopped and looked over to the control panel and saw the Doctor's sonic screwdriver lying on the ground. Sam looked at the Doctor and the Doctor nodded. Sam started slowly making his way over to the control panel as to not attract the attention of demons.

The Doctor had to find a way to communicate with Sam without tipping off the demons, he was their only hope now.

"So Krammeyer," The Doctor began, calling all of the attention of the demons, "What's your big plan?"

Krammeyer just turned and stared at the Doctor. Dean breathed a sigh of relief, he knew the Doctor was good at stalling.

"Come on, you must have a big plan! Everyone does, or at least all bad guys do. Well, most bad guys do, at least the ones that I've encountered do."

"I do have a plan, to kill the Winchesters." Krammeyer sounded very pissed off now. But the Doctor didn't care, he had bought Sam enough time to get to the control panel.

Cas had just been overpowered by three demons and one was holding an angel blade against his throat.

Sam had gotten to the control panel but he had no idea what to do next, there were so many buttons to press. He looked back to Krammeyer who was now walking towards the Doctor.

"Listen, that's not going to get you anywhere," The Doctor said drawing out the word listen, that caught Sam's attention, "You're going to make a lot of people blue. Then they'll all come after you, I'll make sure of it." The word blue didn't fit well in that sentence but Krammeyer didn't seem to care. Sam got the message, but there were a lot of blue buttons.

"What makes you think you're getting out alive?" Krammeyer snorted, "I'm going to kill you right after I finish the Winchesters."

"What am I? The second from the right on your list?" The Doctor shouted and Sam understood the message, Dean just looks confused. Krammeyer realized what the Doctor had done too late. By the time he looked at the control panel, Sam had already pressed the button.

"What have you done?" Krammeyer shouted as some electronics came to life and started to flash.

"I know how Laplji technology works. I simply reversed it, they had no right interfering with Earth's affairs." Krammeyer threw the Doctor across the room in rage. Demons around the room begun coughing and some started to collapse. Cas had no problems freeing himself from the demons holding him but he refrained from killing them. In Krammeyers fit of rage, he released his hold on Dean and he dropped to the floor. A few demons tried to leave their hosts but something was holding them back. Then a cloud of black smoke with purple streaks left its host and the body fell over.

"You and your friends will not be able to possess anyone for a least a hundred years," The Doctor said getting up off of the floor. Other demons had begun to get expelled from their bodies with the purple streak in their smoke.

"You will die for this Doctor!" Krammeyer shouted as he started crushing the Doctor's windpipe. Dean had retrieved his angel blade from the floor and snuck up behind Krammeyer and killed him.

"Thank you," The Doctor said.

"No problem."

Sam and Cas had now made their way to the Doctor and Dean, but they all kept their distance from the Doctor.

"Let's get out of here," Cas said and everyone nodded in agreement. Everyone had questions for the Doctor which had yet to be asked but now they were one step closer to figuring out who this man really is.
