WARNING: Re-edit. Also, spoilers for season 3 finale "No Rest For The Wicked", and slight gore.
Author's Note: This is looking at the post-traumatic stress that Sam had to have experience after "No Rest For The Wicked".
Disclaimer: I don't own Supernatural.
Blood.
The thick red liquid trailed slowly out of the open wound on Dean's shoulder, and Sam felt sick just looking at it.
It wasn't that Sam hadn't seen his fair share of blood before. He'd seen a lot of it. Tons of it. Heck, he'd even been drinking it as of late…
It also wasn't that Sam hadn't seen Dean bleeding before.
Plenty of times he had witnessed his brother come back to their motel more banged up than most men after walking through a war zone. So the sight of his brother's blood shouldn't bother him so much, right?
That would be true, if the last time he had seen Dean bleeding hadn't been right after a Hellhound attack.
Sam had seen Dean lying there, practically in ribbons on the floor, and he could do nothing but cry at the sight of the tattered remains of the brother who had taken care of him his whole life.
So now, as Dean asked him to go get their medical kit so he could "put some stitches in this damn thing", Sam remained rooted to the spot.
He felt slightly dizzy and his legs were sure to give out from under him if he tried to move at all. Images of Dean writhing on the floor has he struggled to fend off the beast that ripped into his flesh flooded Sam's brain.
He wanted to cry out, to do something, anything!
He wanted to distract the hound, or to kill the thing.
To save his brother.
He had to save his brother!
And he couldn't. He couldn't do anything but watch as his brother was ripped from his life.
Was just plain ripped apart.
"Sam?" Dean's voice was suddenly a lot less irritated and a lot more concerned. "You ok Sammy?"
Sam snapped out of his traumatic flash back, and his brain processed the real situation.
Dean had a deep cut on his shoulder. It wasn't from a Hellhound. Dean was alive, and safe, and just needed a few stitches.
Dean wasn't going to be taken from him again anytime soon.
Sam took a deep breath and felt the fuzziness in his head subside a little.
"Yeah. Yeah, I'm good." Sam said as he turned and headed for the bag with their medical supplies inside.
Because you're good. He added silently.
Secondary Author's Note: Thanks for reading! :) Sorry about the gore, but it would kind of be a part of a traumatic flash-back to such an event...
