Getting out of the building was hard, Castiel has no idea how they didn't wake anyone with shooting in front of every door, but they managed. Sam flanked their back, while Dean held Castiel tight and escorted him down each flight of stairs, hallways and out the front door. A sleek, black 1967 Chevy impala, 327, 4-barrel, V-8 engine, automatic, 4-dr, hardtop waited in front of the building for them, shinning under the moons light, inviting a driver.
Dean ushered Castiel into the passenger seat as Sam jumped in the back and Dean ran around to get in the driver's side, starting the car and pulling out within seconds.
"it's ok, you're safe now" Dean says, resting his hand on Castiel's thigh, as if to reassure him. Sam eyes Deans hand suspiciously, but stays quiet.
Even though Castiel was just attacked by a ghost and his knowledge on the world has widened, he can't help but comment "nice car!" as he examines the interior, ignoring Dean's words and forgetting the ghost.
The smile that is plastered over Deans face makes him seem like a big five year old that was just given a complement on one of his drawings.
"I know right, this is my baby" as he speaks, he pats his hand lovingly over the dash, as if patting a pet dog, like the car is alive and can feel his love.
Sam snickers from the back seat and Dean glares at him through the rear vision mirror and for the first time tonight, Castiel can tell that their brothers.
After a long drive filled with talk of cars and a number of science fiction films and tv shows which all three men are fans of, Castiel finds himself shocked when they finally do reach the cemetery. The mood in the car shifts and Castiel can't help but shiver.
When they get out, Castiel spots the sign and walks towards it, not waiting for the hunters as they open the boot of the car to get weapons and shovels.
Dean hurries so that he can catch up to Castiel in case danger occurs, but when he tries to leave ahead of Sam, his brother grabs his arm, stopping him quickly and leaning closer.
"What's with you and him?" Sam asks hushed, even though Castiel won't hear them from his distance away.
"What do you mean?" Dean asks, puffing out his chest as he looks up to his little brother.
Sam's hair falls down in front of his face, hiding the twinkle in his eyes as he smiles, "you two have been having eye sex ever since you met, and it seems like you can't keep your hands off him"
Dean blushes and lowers his gaze, proving Sam's point.
Sam's soft smile, turns to a frown as he becomes thoughtful and looks off at Castiel, who is now sitting in front of a grave, staring at it intently, "just don't forget about what happened to Benny, I don't want you to get hurt.
Dean looks up to Sam as if to say something, but can't think of anything intelligent, so simply just nods before Sam turns, picks up the shovels and starts walking to Castiel.

ok, i don't really do into Benny's death to much, but i hope its obvious that he died while hunting with the brothers.
Benny was also a human, not vampire.
hope you enjoyed!
