Hello! Welcome to this story of Supernatural. This story might be small or might be long. Depends on the reaction I get from it, you know?

This takes place after 9x11 and somewhere between the next episode. I made my own episode basically because we don't know how Cas and Sam are going to react to Dean's new tattoo.

PS: I listened to 'Hey Brother' by Avicii nonstop while writing this. That song relates to Dean and Sam so much!

Warnings: None really…

Summary: Takes place after 9x11 'First Born'. Dean runs into Sam and Castiel during a case, working on the case together. During the case, Dean hides the fact that he has a burning mark on his arm underneath his suit jacket. Dean tries to get away from Sam and Cas before they find out.

'Please (don't) leave me alone'

Dean pulled on his suit jacket, covering the burning mark on his arm. Yesterday, he was woken up by a burning sting where the Mark of Cain now laid. He had to brush off the pain as he headed off to a new case, all alone. Of course he missed Cas and Sam but Sam made it pretty clear that he was to go and now that he got the mark of Cain, who knew what he could do. Dean needed to stay away from Sam and Cas just in case he hurts anyone.

Dean got into his baby and turned the ignition on, automatically blasting the music. The case this time was in West Virginia and seemed pretty simple.

"Just get in and get out. No need to stay any longer than necessary." Dean said as he turned the car to go down the road.

-West Virginia-

Dean parked the car and stepped out of the impala, grabbing his arm as another heat of pain shot up his arm. He stood there for a second before shaking it off and getting his badge ready. He walked up to the crime scene where a man was clawed to death by something. He fashed his badge when the man gave him a weird look.

"Another FBI? We already have two of you guys."

"Who else is here?"

The cop points at the direction of the house where Dean starts walking up. When Dean gets there, his heart drops and he turns pale. For a few yards away is the two people he wanted to protect. Sam and Cas are talking to a cop so their backs are turned away from him.

"I got to get out of here." Dean whispers as he turns around and starts walking away when there's a groan behind him, stopping him in his tracks.

"Another FBI? Seriously, it's probably just a bear!"

Dean could hear feet turning around and a sharp intake of breath. He lets go of the breath he was holding and turns around to stare into the eyes of his angel and brother. They seem shocked to see him but also relieved. Dean clears his throat.

"Yeah well, it might also not be a bear and we just need to make sure."

Dean shifts on his feet and puts his hands in his pockets. He looks at Sam and Cas, who start to smile, before looking down at his shoes.

"Well, leave you three to… whatever."

Dean moves slightly to let the cop go through the doorway behind him before picking up a file nearby and start working.

"Alright, we have a man come home from his ordinary job then an hour later, his wife comes home to find him mau-."

Dean stops talking as he gets grabbed and pulled into a hug. Sam wraps his arms around Dean and holds on tightly to Dean. Once he lets Dean go, Dean barely has a chance to breathe before Cas pulls him into a hug as well. Dean lets it happen because deep down, he knows this is what he wants.

Cas lets go of Dean and gets put in the middle of the two.

"Where have you been Dean?"

Dean looks at Cas and Sam before feeling a little anger bubble up in his chest.

"I left like you told me to, what do you mean where have I been?"

Sam shifts at his feet before looking down. He looks up at Dean with a guilty look on his face.

"I know I told you to go Dean but… we can't- we won't do it again. Please, come back."

Dean looks shocked at Sam and looks at Cas for confirmation, who just nods. Dean could feel his throat getting tight from emotion. I want to go back… so badly, thought Dean, but… I need to protect them. From me.

"I-I don't know."

Sam puts his hands up and smiles at Dean.

"No chick flicks dude. Come on, we have a case we need to do, right?"

Dean doesn't trust his voice so he just nods. Sam smiles before clapping Dean on the shoulder and going on about the case.

-Motel-

"It felt like forever since we've been in a motel." Dean says as he plops down on the bed, groaning at the not-so-cushion mattress. Sam looks at Dean and laughs.

"I know… Don't think I missed it all that much."

Dean groans in agreement before sitting up and taking off his shoes. He starts to take off his jacket but feels a burning sensation on his arm and rethinks it. He shifts his jacket and starts working on the case. Cas looks at Dean confusingly.

"Dean, aren't you going to take your jacket off?"

Sam looks at Dean and raises an eyebrow because Dean usually rips his jacket off. Dean shifts before shaking his head.

"Uh… No. I happen to like professional unlike you assbutts."

"That's my line Dean."

Dean smiles at Cas's offended tone and raises his hands up in surrender.

"All yours dude."

Dean gets straight to work and tries to ignore his family's burning gaze but can still feel it. It's almost as worse as the burning on his arm… almost.

A few hours pass by and Sam comes back with takeout for both Dean and him because Cas won't eat anything. "I can taste all the molecules… It's overwhelming."

Sam reaches into the greasy bag and takes out a cheeseburger and a drink for himself then grabs Dean's burger and shake, hnding it to him. Dean shifts his jacket and makes a face when he does it. Alright, time to take off the jacket. Thought Dean. He stood up and went to his bag to grab a new long sleeve shirt and turned to change in the bathroom when he felt himself being watched. He looked at Sam, who looked sad and worried at the same time.

"What?"

Sam walked toward Dean before shaking his head.

"You just seem different. I'm glad we're all back together."

Dean clears the lump in his throat and, once again, shifts on his feet.

"Yeah well… Me too." Dean smiles at Sam and pats his shoulder. Sam walks away and Dean turns to walk into the bathroom when he hits his shoulder against Cas's. Cas stops when Dean hit his shoulder and his eyes widen.

"Sorry Cas. Didn't see you there."

Dean looks at Cas before looking down and walks toward the door when Cas grabbed his arm, the arm with the Mark and dragging him backward and in site of Sam.

"What the hell Cas?!"

Cas doesn't say anything as he practically throws Dean on the motel bed.

"Cas! What's going on?!" Sam is now standing near Cas, who isn't speaking yet. He comes toward Dean and grabs his suit jacket sleeve and tugs, ripping it clean off and revealing a burning red mark.

Dean jumps as Cas did this and then felt panic as he heard his suit rip. There was a moment of stillness until Dean covered the Mark of Cain.

"Dean… Wha-?"

Dean stood up and pushed past Sam, grabbing his keys. He slammed the door open and walked out.

"Dean!"

Dean turned on his Impala and pulled out just as Sam and Cas walked out of the motel room. He looked at them just as a tear fell from his eyes and drove off.

"DEAN!"

'Please (don't) leave me alone'

Sorry for that ending but it seemed appropriate. If you want me to continue this, just leave a review and I will. It might take a while but I'll get to it eventually. Also, let me know if this story should be a two-shot or a multichapter story.

Thanks for reading!
