CAIN'S HOUSE

Dean and Crowley sit inside Cain's house on a couch. Dean is looking around assessing their options and Crowley is staring at the floor looking like he's about to panic.

"Why don't you just zap out of here?" Dean Asks

"I'd never leave my domestic partner in crime." Crowley Says

"Yeah, like your heart grew three sizes. You can't zap out of here, can you?" Dean Asks

"Cain's doing something to me." Crowley Says

"Well, it's not your day for getaways, is it? All right, so, tell me about this Cain." Dean Says

"Well, after Cain killed Abel, he became a demon." Crowley Says

"What do you mean "became a demon"?" Dean Says

"I mean he became the deadliest demon to walk the face of the earth. Killed thousands. The best at being the worst. And then he just... Disappeared. Everyone thought he was dead or, at least, hoped he was." Crowley Says

Cain enters with a tea tray and Crowley cowers

"Do either of you keep bees? It's very relaxing. They're such noble creatures. And the honey? Well, I keep it right on the comb." Cain Says

he sets the tray down on the coffee table and hands Crowley a cup. He takes it but his hands are shaking in fright and so the tea cup rattles suspiciously.

"There you are..They're dying, you know. Without bees, mankind will cease to exist. So, what are the King of Hell and a Winchester doing at my house?" Cain Asks

"You know who we are?" Dean Says

"I'm retired. I'm not dead. What I don't know is why you're looking for me -- more importantly, how you found me." Cain Says

"Ah, that's, uh, a funny story, really. Bit of a misunderstanding. We really should—" Crowley Says

Cain makes motions with his hand and Crowley is rendered speechless.

"Shh." Cain Says

"Oh, you gotta teach me how to do that." Dean Says

"Why are you here, Dean?" Cain Asks

"We're looking for the weapon the archangels used to kill the Knights of Hell. The First Blade. We need it to kill a Knight of Hell -- Abaddon." Cain absentmindedly moves a ring on his left ring-finger. He subtlety notices. "Look, I get it. You're retired. We're not here to get between you and the demonic AARP, but it's bad out there, and I'm just looking to even the odds." Dean Says

"One last time -- how did you find me?" Cain Asks

"We didn't. The location spell was for the blade. One-time deal." Dean Says

"Anyone else know you're here?" Cain Asks

"No." Dean Says

TARA'S PAWN SHOP

The stalker demon from the bar enters and Tara's knee hitches painfully.

"Excuse me, ma'am. Wonder if you might have seen some of my friends pass through here. Big guy, kind of funny ears." Demon Says

Tara glances at the floor and the busted Devil's Trap. She makes a dive for her shot gun and shoots The Demon point blank in the face.

CAIN'S HOUSE

"Well, it's been a pleasure having company, but once a century is enough for me. You can let yourselves out." Cain Says

"Hey, listen, pal. We're not leaving here without the Blade." Dean Says

"You have quite a reputation, Dean. I see the part about you being brave rings true." Cain Says

"Well, what can I say? I'm an all-in kind of guy. Abaddon is the last Knight of Hell, and if you're out of the game, what the hell do you care if she dies?" Dean Asks

"If your friend here could talk, he would tell you that I trained the Knights of Hell. I built that entire demonic order with my own hands -- Abaddon included." Cain Says

"Well, that is information I could have used five minutes ago!" Dean Says As Crowley gasps in explanation, still unable to talk

"Well, here's something your friend doesn't know, that no one knows, in fact -- outside of Abaddon. It wasn't the archangels that slaughtered the knights. It was me."  Cain Says

"Why did you turn on your own?" Dean Asks

"Once again, I admire your bravery. But if you'll excuse me, I have errands to run in town." he turns his back to leave "Goodbye, Dean Winchester... Never return." Cain Says

Moments later Crowley and Dean exit the house.

"Well, that was lovely. Can we leave the country now?" Crowley Says

"But you said the First Blade was our only shot at killing Abaddon. This is the closest you've been to it. We're not leaving." Dean Says

"Will you listen to reason for once?" Crowley Says

"Hey. He said he was going into town. Awesome. We wait till he's gone, come back, bust in, take what's ours. Got it?" Dean Says

BUNKER MAIN ROOM

Sam and Castiel are walking down the stairs in the main room.

"Sam, may I ask you a question?" Castiel Says

"You just did." Sam Says

"Can I ask you another question?" Castiel Says

"Well, technically, you -- yeah, go ahead. What's up?" Sam Asks

"Sam, the trials. You chose not to go through with them for a reason, didn't you? You chose to live rather than to sacrifice yourself. You and Dean... You chose each other." Castiel Says

"Yeah, I did. We did. And then... Dean made a choice for me." Sam Says

Sam clearly not wanting to talk about it walks off to the medical room. Castiel follows.

"What Dean did --" Castiel Says

"It doesn't matter what Dean did. Look, I could have put a stop to all this, Cas. I could have closed the gates of hell." Sam Says

"Oh, Sam." Castiel Says

"Dean's gone, okay? This is on me now, and if I can find Gadreel... I can fix this." Sam Says

He sets a box down on a table next to a gurney. He talks off his plaid button-up shirt leaving him in just a thin t-shirt.

"Now...being a human means settling your debts."
He hands the box to Castiel and sits down on the gurney "Let's start balancing the books." Sam Says

Castiel opens the box and it is revealed to contain the huge needle pictured in the file.

CAIN'S HOUSE

Dean and Crowley entering Cain's house and begins searching around.

"This is by far the dumbest idea you've ever had." Crowley Says

"Yeah, well, it's early." Dean Says

Crowley peeks in the front room and then backs away "Oh, there's nothing here. Shame. Let's go."

"Hey! Sack up and start looking, okay? We don't have that much time." Dean Says

Dean looks around the living room and as he does he notices a picture on the mantel. He picks it up to look closer. It is a old picture of a woman and it says Colette on the bottom. He looks closer and notices that she is wearing a ring very similar to the ring on Cain's hand.

Outside the house, The Demon from earlier drives up in a huge truck. He is on the phone.

"You'll never believe what the Winchester and Crowley found. Send back-up. Send...Everybody."

He hisses painfully as he pulls the phone away from his ear and we can see that his ear is missing and most of the skin on the side of his face is blown away from Tara's shotgun, He looks at his face in the mirror.

BUNKER MEDICAL ROOM

Sam is lying on the gurney and Castiel has the huge syringe needle posed to extract some angel grace, Corinna is there as well watching along. He punctures the needle into the side of Sam's neck, right below his left ear. Corinna tries look away as Sam gasps in pain.

"Now comes the part that will actually hurt. I'm gonna begin the extraction." Castiel Says

W slowly pulls back the plunger and the bottom of the syringe barrel fills with a tiny bit of angel grace. Sam is trying very hard not to cry out from the pain.

"Is it working?" Sam Asks

"Yeah." Castiel Says

"But?" Corinna Says

"I-I need to push the needle in deeper. We need more Grace in order to cast the spell." Castiel Says

"Okay. Do it." Sam Says

"Sam, if I get too close to—" Castiel Says

"Damn it, Cas! Just do it." Sam Says

Castiel slowly pushes the needle deeper and starts pulling back on the plunger again. Suddenly, Sam's body lurges and he has flashbacks to images of when Gadreel was inside of him and then to some of the moments when he was performing the trials.
Castiel pulls out the needle.

"What the hell was that?" Sam Asks

"Your body is regressing to the state it was in before Gadreel." Castiel Says

"Do we have enough Grace for the summoning spell?" Sam Asks

"Sam." Corinna Says

"Do we or not, Cas?" Sam Asks

"No." Castiel Says

"Then keep going." Sam Says

Castiel and Corinna again looks very concerned and reluctant. Castiel pushes the needle in Sam's neck again, he gasp in pain. Sam reaches for Corinna.

"Corinna." Sam Says

"Yeah yeah I'm here." Corinna Says

"Hold on my hand, please." Sam Says

Sam takes Corinna's hand and holds it, she squeezes it.

"Sure." Corinna Says

CAIN'S HOUSE

Dean and Crowley are still searching through out the house.

"Nothing. Not even porn." Crowley Says

"Think I figured out why he went off the reservation so many years ago." Dean Says As he hands the picture of Colette to Crowley

"Lovely. Little plain. Who is she?" Crowley Asks

"Cain had a similar ring on. Father of murder got hitched." They look up as they hear all the doors in the house lock. "He's back. Come on." Dean Says

Cain appears behind them. He motions to the picture Crowley still holds in his hand.

"That belongs to me." Cain Says

"Sorry." Hands the picture of Colette back to Cain "Gorgeous, by the way." Crowley Says

Headlights flash from the driveway and Dean walks to a window and draws back the curtain. It is The Stalker Demon with five more demons in tow, Katherine gets out a car as well.

"..Katherine, I don't suppose they're with you." Dean Says

"No." Cain Says

"I guess we can't wait any longer. Your friend Tara was very helpful! Got downright chatty... After I peeled all her skin off."

"We don't want any trouble, Cain. Just want the so-called King and the Winchester. We all got a Master to impress, and I'm betting bagging those two will do just that." Katherine Says

"Master"?" Dean Says

"Abaddon. This lot all need to die. I count—" Crowley Says

"Too many..The whammy you put on the doors that keeps us in. Will it keep them out?" Dean Asks

"For now." Cain Says

"I'm gonna barricade the entrances. Get ready for a fight." Dean Says

"Well, good luck with that." Cain Says

"What?" Dean Says

"You exposed my home. You exposed me." Cain Says

"Well, boo-hoo!" Dean Says

"Brave, but impulsive. You truly have lived up to your reputation." Cain Says

"I can't say you've lived up to yours." Dean Says

"What can I say? I'm retired. If you survive, you're welcome to join me for the last meal I will eat in this house before I disappear again. It's the least I can do." Cain Says

Cain sets his groceries on the table and Dean and Crowley exchange looks.

BUNKER MEDICAL ROOM

Sam is gripping onto Corinna's hand tightly as Castiel is still extracting angel grace and he is almost unconscious from the pain.

"Sam? Sam?!" Corinna Says

"No Cas..Keep going." Sam Says

"Why?" Castiel Asks

"We -- we -- we have to find Gadreel." Sam Says

Castiel looks at Corinna and sighs then starts to remove the needle from Sam's neck.

"No Why must the Winchesters run toward death?" Castiel Says

Sam grabs the syringe in Castiel's hand and stops him from removing it.

"No, don't. Don't. Don't stop." Sam Says

"Sam, when I was human, I died, and that showed me that life is precious, and it must be protected at all costs, even a life as... as pig-headed as a Winchester's." Castiel Says

"My life's not worth any more than anyone else's -- not yours or Dean's, or Corinna's...or Kevin's. Please. Please, help me do one thing right keep going." Sam Says

Corinna looks away again as Castiel pushes the needle in further, Sam squeezes Corinna's hand while he screams in pain.

CAIN'S HOUSE

Dean is pushing furniture in front of all the doors. He looks at Crowley.

"All right, I got this. You take the front." Dean Says

Crowley moves to the living room; closing the glass doors behind him. Cain sits down at the table and starts to pull husks off the corn in front of him.

"So, this is your play?! Corn?! What am I not getting here? I mean, it's not like you're a coward." Dean Says

"Since when does the great Dean Winchester ask for help? Well, that doesn't sound like the man I've read about on demon bathroom walls. Maybe you've lost a step. Let's find out." Cain Says

He snaps his fingers and the door and the fridge in front of it fly open and The Demon and a Girl Demon rush in. Cain snaps his fingers again and the door slams shut in front of the others outside.

"Oh, don't mind me..Enjoy yourself." Cain Says

Dean pulls the demon knife from his jacket as a third demon crashes through the glass doors behind him. He flinches as glass sprays his back. He turns to face The third demon, swings the knife at him but the demon ducks and punches Dean in the stomach.

Dean gets in a kick but the demon sends him flying across the table and onto the other side with Stalker Demon and Girl Demon. Cain watches the whole thing while sitting at the table shucking corn. Stalker Demon swings at Dean but he grabs his hand and pulls it over his shoulder. He stabs the knife into the demon making him glow yellow and die.

As Stalker Demon falls to the floor Girl Demon grabs Dean from one side and Window Demon kicks the back of Dean's left knee making his legs buckle. The two demons grab Dean's arms and flip him up onto the table on his back. Girl Demon steals the demon knife out of Dean's hand. As Dean struggles to get a upper hand, Cain calmly leans over.

"Doing great." Cain Says
