You and Sam have been working in the bunker to cure demon Dean. When he's ready for his next dose, you both go back only to find him gone, the demon cuffs broken on the floor. You look at each other and then silently nod at each other, deciding to split up.
Sam runs towards the electrical room and you run towards the garage, angel blade in hand. As you make your way over to the garage, you can hear the distant sound of demon Dean yelling about wanting to kill you both.
Sam flicks the breaker and bathes the entire bunker in a red flashing glow as you make your way down the hallway, finally making it to the garage and hiding behind one of the many cars. You can hear footsteps now as Dean taunts the two of you. You steel yourself, anticipating the inevitable fight between you and Dean as you hear him kicking doors in.
Eventually, Dean makes it to the garage door, kicking it open and looking inside. The red glow of the room illuminates the red collar shirt and jeans he has on, the hammer in his hand... and the inky black eyes where that beautiful familiar green used to be.
You carefully and quietly get into a better position to lunge, readying the demon blade in your hand as he walks into the garage.
"Come out, come out wherever you are," he taunts, a cheshire grin spreading across his face.
You take a deep shaky breath, preparing yourself to fight and probably die. Dean's eyes lock onto your location, almost as if he could hear your breathing. You freeze as he starts to approach you, a sadistic smile on his face.
"There you are, little birdie."
