Author's Note: AHAHAHA OMG WHAT IS WRONG WITH MY BRAIN. Just reread all the rest of it so I could finally write a bit more… the only excuse for this series is that I am completely insane. Also I'm sorry, I feel like this chapter is short and kind of limps along. And after it took me so long to get it out to you in the first place... Added a surprise guest, though, so that's something. Anyway, here's the moment you've all (maybe?) been waiting for.

Ellen didn't have a full-blown panic room like Bobby, but she did have a spare bedroom on the ground floor that had been renovated into their weapons storage, and that was where the hunters retreated to. Grabbing a stick of chalk, Sam drew a devil's trap just outside the doorway, covering it with the hall rug, and one just inside the doorway which he didn't bother to hide. He doubted that either would trick Dean, but their options for defense were limited. As he poured salt across the doorway, Ellen sat Jo at a table in the center of the room and wrapped her in a sweatshirt, murmuring softly and reassuringly.

"What are we gonna do now Sam?" Ellen's voice was low, and although she was controlling her expression well, Sam could see the terror in the depths of her eyes. Above them, a crash echoed through the building, making Jo flinch and whimper involuntarily. Sam glanced around helplessly, wondering what he could possibly do. Out in the hallway, a floorboard creaked, and there was a brief scratching sound as Dean disabled the trap Sam had left. Then the door began to shudder as Dean pounded on it from the outside.

"Knock knock, little brother," the demon crooned through the wood. "Let me in Sam. I'm not going away this time. I haven't got anyplace I'd rather be then here, and nothing else I'd rather be doing. Well, except maybe Jo." Behind Sam, Jo gave a muffled sob, and the demon laughed and rattled the door again. Despite the protections he had put up, Sam grew more nervous by the second. Dean was incredibly powerful, and once Jo's spell was broken and he got his powers back, Sam had a sinking feeling that salt and Devil's Traps wouldn't stop him.

"Do you have any idea how long your spell will last, before he's back to full strength?" Sam spoke quietly, but a snarl from outside told him that Dean had heard him.

"I know you're anxious to see me, Sammy, but don't worry. It should only be a few more minutes."

"I— I don't know." Jo swallowed, getting herself under control. "He's right, we've got less than five minutes."

"Do you have the knife, Sam?" Ellen kept glancing nervously from Sam to the doorway and back.

"Yes, but I don't know how much good it will do. He's too strong." Bleak despair filled Sam as Dean started laughing again in the hallway. Ellen and Jo were going to die now, just like Bobby, and it was all Sam's fault. No, he told himself sharply. There had to be a way to get out of this. He pulled his phone from his pocket, but there was no service. Dean had taken out the cell towers too? That meant the landlines would be cut as well. No calling for help. At least they had weapons, but would they have any effect on that monster? In desperation, Sam closed his eyes and started to pray to anyone, anything that might be up there and listening.

There was a sudden sound vacuum, as though all the air had been sucked out of the room. The noise of Dean pounding on the door became muffled, and Sam glanced frantically around, wondering what fresh hell this was. To his alarm, there was a stranger standing just behind him, between him and the girls. Sam's knife hand flashed forwards, but the intruder caught it with impossible speed, stopping the tip of the blade inches from the crooked blue tie he wore. Sam tried to wrench his wrist free, but the stranger's grip was like iron and all of Sam's struggles were futile. Behind him Sam heard Ellen curse, and then the roar of her shotgun emptying into the back of the man's heavy trenchcoat. He barely flinched, although Sam saw faint confusion in his blue eyes.

"Sam Winchester?" he asked in a gravelly voice, although it was more of a statement that a question. "I have heard your prayers."

"You what?" Sam asked, still desperately trying to break free. "What are you, how did you get in here?" Outside the room Dean stopped trying to break in, and it was silent as though the whole world was waiting on the answer. The man cocked his head to one side and stared at Sam as though he didn't understand the question.

"I came because you called. My name is Castiel. I am an angel of the lord, and I am here to answer your prayers." All three hunters stared in disbelief. Even Dean had no response from out in the hall.

"Since when do angels dress like… like lawyers?" Ellen asked, the muzzle of her gun wavering between the man and the floor. Jo had found a knife somewhere and held it in front of her, shaking.

Castiel glanced down at his clothes, then over his shoulder at Ellen. "This? This is not my true form; it is only a vessel." Ellen gave a slightly hysterical chuckle of disbelief.

"Why should we believe you?" Sam challenged. Castiel had dropped him, and Sam circled around so that the angel was no longer between him, Ellen, and Jo. Castiel revolved with him, apparently unconcerned about putting his back to the demon outside.

"Your belief or lack of does not change my existence, Samuel. Do you want my help, or not?" The man looked slightly irritated now. "It is a great honor to have an angel personally assist you."

"Oh?" There was a rumble of not-quite thunder, the lights flickered, and then the door exploded inwards. Sam ducked, covering his eyes, but all of the flying chunks of wood deflected away from Castiel and those in front of him as though they had hit a wall. Very deliberately, Castiel turned to face Dean, who stood triumphantly in the doorway. The demon's eyes gleamed black, and the smile on his lips was feral.

"Guess who's all juiced up again?" Dean took a step into the room and spat on the chalk lines before him, swiping a foot through them to destroy their effectiveness. "So, Cas." The angel's eyes narrowed at the nickname, but he said nothing. "Whatever did my brother do to warrant all this heavenly attention?"

"Sam Winchester is a good man. I heard his prayer and found him deserving of my help." Castiel sounded just as relaxed as ever, and Sam wondered if the angel just didn't know what he was facing. Behind him, he heard Ellen quietly reloading her shotgun. Jo took a pistol and raised it to point at Dean, although her hands were shaking. Sam gripped the demon knife tighter, ready to fight to the death. For the moment, though, it seemed as though Dean and this Castiel person were trying to get the measure of each other.

"My Sammy? A good man? I don't know where you're getting your information, Cas. I hear he killed his surrogate dad and tore his heart out." Dean smirked at Sam over the angel's shoulder. Sam's stomach rolled, and he bit down on a sob. He would not let Dean manipulate him like this. The angel seemed unamused.

"My name is Castiel, demon. Be gone from here, and torment these people no further." Despite not having a visible weapon, Castiel had a dangerous aura about him that made Sam shiver. Dean didn't seem impressed. The smile dropped into a scowl, and he stalked forwards a few steps.

"I'll call you whatever I want, Cas. And I would appreciate it if you gave me my prey back, I wasn't done with them." Dean raised his hand and made a flicking motion, as though Castiel were a fly he would brush away.
