There's too much blood and they know it. This is it. No more redos, no more reset button. Dean looks over at where Sam's sprawled on the ground 3 feet away. He can barely breathe, ribs skewering his insides, and all he can taste is blood and bile. But he can still see Sammy. Even if Sam can't see him. His baby brother's hazel eyes are slowly, but surely glazing over.
Dean feels it coming, the dark, it's eating away at the corners of his vision and mind. He searches for something to say, anything in this last moment, but all he manages to cough out is one, final, single word.
"Bitch.."
Sam laughs and it's wet, hacking, his last breath. "Jerk." he replies and they both know, sure as anything, that what they're really saying is "I love you." and "See you soon."
