Thunder roared overhead as Dean shakily grabs a shotgun off the wooden floor. He then drew in a breath and releases it in one fluid motion as he tries to clear his head of any fear. One movement would end this fight, but the eldest Winchester knew he wouldn't do it. Dean knew he couldn't just pull the trigger on him like that, just rip Sam's life out of him like tearing a sheet in half. He let another fluid breath escape his lips as he turned the corner, trying to find his brother...his Sammy.
"Dean please!" A small voice pleaded from down the hallway, and Dean exhaled deeply. "I promise, I won't hurt you!"
Dean then kicked the door open, wood crashing into wood. His cold green eyes widened as he saw the shape his brother was in, the pain that he may of felt. "Just let me do this Sam...it'll be quick."
Sam was a mess, his brown locks all tangled and matted against his head. His eyes were filming over and bloodshot, his vision going second by second. Blood was bubbling all across his back, the flesh torn and frayed where the undead bastard had raked his claws across his fragile skin. Sickly yellow pus had caked along the wound, turning the skin a pale green color. Sam was changing, and Dean knew he had to put a bullet in his brother's head before he changed his mind.
"I'm sorry Sammy, I wish it could of been quicker than this. You're in so much pain and I-"
"You can't do it, can you Dean? You can't get yourself kill me, can you? I'm the last family you have, since Cas and the rest of those fucking angels are locked away in Heaven. Those winged freaks are covering their asses while they wait for their Ark to come. Noah is not going to come, and we both know it. The apocalypse is ending humanity once and for all, but those bastards can't see that. I can't blame you for not wanting to kill me, but you gotta man up. You'll find someone else, trust me, and they'll treat you better. I love you Dean, so do it." Sam pleaded, his eyelids feeling heavier and heavier.
Dean chuckled, raising the weapon and pointing it at his brother. "Goodbye Sam. I hope Billie treats you well."
He then squeezed the trigger.
"Hello Billie."
"Hello Sam."
