When Dean opened his eyes again, at least a few minutes had past. Sam was on the ground next to him.
At first, Sam had not moved from the place where he had curled up. Every tiny movement had hurt, leaving him groaning quietly in the dirt. Now, Sam was finally able to sit up and even started to lift himself to his feet. But he was obviously having some trouble doing so.
When Dean saw the movement in his periphery, he looked up and was shocked by what he saw. Sams whole face was covered in blood. It was streaming down from his nose and a nasty cut over his left eye which was already swollen. Sam held his arm protectively over his ribcage – where Dean had kicked him several times – hissing with every move.
That was the moment Dean realized what he had done.
"Shit Sam, I am so sorry" Dean got up wanting to help his brother but Sam flinched back as soon as Dean moved in his direction. He hadflinched.
"I didnt...Im so sorry, Sam..." Dean stammered lifting his hands in surrender and watching his little brother unsteadily climb to his feet.
"Its okay...Dean...you are right...I had it coming" Sams voice was full of pain and Dean could hear how much effort he had to put just into speaking.
When Sam tried to straighten up he immediately hunched down in pain and started coughing. Dean jumped next to him right before he would have dropped to the ground again. Even now Dean could feel Sam leaning away from him, but Sam couldnt stand on his own and nearly fell again.
It broke Deans heart to see his little brother – the one he had sworn to protect with his own life – now hurt by his own actions.
"Please Sammy, just let me help you." Sam didnt answer him but he let Dean lay his arm around his waist and put his own arm over Deans shoulders for support. Like this, the two brothers hobbled into the house and Dean helped Sam lay down on the living room couch.
He was relived when Sam let him clean his wounds and felt guilty and sick seeing the colourful bruises on his brothers chest. Sam fell asleep pretty soon after, exhausted by everything that had transpired.
Dean wanted to stay by his side but decided against it. Sam would probably dislike seeing him first thing when he wakes up. So he went into the kitchen opened a bottle of beer and sat at the table. He didnt even take a sip of his beer, recapitulating what had happened. He repeated every word he had thrown at Sam and just sat there shaking his head in disbelieve. How could he have done this?
But then something hit him. Sam hadnt even tried to defend himself. Not with words and not physically. He just lay there and let Dean hit him, not moving an inch.
