Immediately, Sam slammed the door in its face, racing back into the kitchen, knocking over a chair in the process.

"What's going on?!" Kevin asked, jumping in his seat as the chair fell with a loud bang. Bangs and clinks soared through the air as Sam fumbled through one of the drawers, muttering a curse as he sliced his palm on the blade of a particularly sharp bread knife.

"You okay there, buddy?!" Dean repeated, walking briskly over to his brother, grabbing his hand ftp have a look. Sam jerk it away, clutching the handle tightly, stinging where his blood emptied onto the wood.

"I'm fine, I'm fine," he said quickly, breathlessly, "it's just-" Without finishing, he went to the front, being pulled back by Dean, who said, "It's just what, Sam?" Sam shook his head- he had thought everything was gone, that they were finally able to live peaceful life and not have to deal with angels or demons and the like. I guess it isn't like that, he thought as he pulled way from Dean without an answer, stalking over to the front door of the bunker. The thing was still banging itself against the door, groaning mindlessly, a jumble of nonsensical bile that could not be translated into words no matter how hard he tried.

"Sam?" came Kevin's voice from behind, making him jump.

"Kevin-"

"Is everything okay?" Kevin asked, his eyes wide as he then heard the bang, the muffled sound, "what was that?"

"it's nothing, Kevin-" Sam began, being interrupted by a long snarl.

"T-that didn't sound like nothing," Kevin joked, following with nervous laughter. Cas looked from one person to another, fear and confusion flashing in his innocent blue eyes. Are more angels here to get me? he suddenly thought, remembering what Hael had said, what she screamed as he left her in the girl's broken body, torn apart and bleeding. He shivered at the memory. Staying in his set, he watched as Kevin came running back, screaming, tears in his eyes.

"Whoa, whoa, whoa!" Dean shouted, grabbing the teenager and cradling him in a tight bear hug, "what happened, kid?!"

"Sam, he-he sat…" Kevin blubbered, his face beet red. Wiping mucus from his nose onto his sleeve, he gulped, "Sam sta-stabbed the zombie and then…!"

"Zombie?" Dean asked hesitantly. h head thought everything had disappeared once the angels had fallen, all of them had tried to find homes and new vessels for themselves.

"Y-yeah…"

"It must be Metatron's doing," Cas piped up, "he must know where we are." Dean shook his head. The bunker had been hidden well for over seventy-five years. He knew that no one knew any way to get in besides the front door that lead tot eh staircase that went down into the ground. Even then it was difficult to find the door, it was so well hidden by vines and vegetation.

"Not possible," Dean said gruff, letting go of Kevin as he padded his way to his room, slamming the door shut.

"Uggghhh…." followed a low groan. Dean rolled his eyes.

"Okay, Sammy, we get it, it isn't funny anymore!" Dean barked, but the groan only came again, turning more into a ferocious growl.

"Samuel!" Cas tried echoing Dean, "just stop, please!" Dean shot him a look, making the angel slink deeper into his chair, playing with his fork on the plate. the groan came again, and in a blur, Sam came rushing in, clutching the knife in his hand so hard his knuckles were turning white, his body trembling.

"Sam!" Dean shouted, why is going on!"

Sam panted, "…Croates…." Swallowing hard, he watched as the zombie shuffled in, head lolling to one side. Its skin was a gray, mottled mess, pieces hanging in long streamers off its bones, an eyeball hanging from its socket. The rotted flesh was stripped away on its face to reveal a bloody red, almost blackened jaw, stumps jutting out randomly. The thing was missing an arm, fresh blood spurting from the wound, trailing on the kitchen floor.

"Sam!" Dean cried, "what the fuck?!"

"Dean!" Sam growled, his eye twitching slightly, "now is not the time-"

"Dean, get behind me!" Cas ordered, pushing Dean behind him. Sam rolled his eyes. Of course Cas was going to save his brother over him. The two did have a profound bond, after all.

"Cas, you cannot do anything in this situation-" Sam began to protest, but the angel had a cold look in his eyes, saying, "i can smite it where it stands, Sam! Back down!"

"You are such an idiot!" Sam bellowed at the angel, "you and Dean just get out! try to protect Kevin in case anymore of them come in!" Startled, Cas obliged, looking like a puppy that had been caught peeing on the rug. Grabbing his hand, Dean pulled Ca sin the direction of Kevin's room, leaving Sa to face off against the undead by himself.

"Shit," Sam muttered to himself, widening his stance, holding the knife out in front of him defensively, "That really was not a good idea…."
