Jake and Sam rush outside, "I'll take the barn and the hotel." Jake instructed, "You take the houses."

"Alright. Meet back here in ten minutes, okay?"

"Okay."

Sam began his walk to the houses as Ava peeked her head out from around the corner, but Sam didn't see her. Meanwhile, Andy stayed back at the abandoned building. When he turned, Ava was standing in the room with him. She dragged her finger along the salt on the windowsill, breaking the line.

"Ava, where'd you go?" He frowned, "Didn't you hear us yelling?"

"Yeah." Her voice was light, nonchalant, "I heard you."

She stared at him a moment before putting her hands to her head in concentration. A cloud of black demon smoke appeared outside the window. Since the salt line had been broken, it was able to enter the room through the window.

Andy watched her and then the smoke in fear and confusion as he backed away, "What are you doing?"

The smoke suddenly materialized into the demonic little girl.

"Holy-"

The demon girl knocked him down and wasted no time in killing him. He screamed in pain, as his blood splattered everywhere until he was completely dead. Ava watched his corpse for a second, amused, then began screaming. Outside, Sam heard her and rushed inside, stopping at seeing her hysterically in tears as she pointed as Andy's body.

"Sam!" She wailed, "I just found him like this!"

Shock filled the hunter, "What happened?"

"I don't know!"

"How'd that thing get in?" He hurried to the window before turning back to her, "Where were you?"

"I just went to get some water from the well. I was only gone maybe, like, two minutes…"

"You shouldn't have gone outside. Ava, we have to stay in here…" He trailed off upon noticing the disturbed salt on the window, "Who did that?"

She shook her head frantically, still crying, "I don't know, maybe Andy-"

"Andy wouldn't do that. Ava, that line wasn't broken when I left." At her silence his jaw clenched, "Ava."

"What?" She scoffed, "You don't think that I-"

"I'll tell you what I think: five months." He glared as he slowly advanced on her, Ava carefully stepping back to match him, "You're the only one with all that time you can't account for. And that headache you got… Right when the demon got Lily."

"What are you trying to say?"

"What happened to you?"

"Nothing!" Sam stared her down until a minute later, she dropped the act, and chuckled, "Had you going though, didn't I?" She wiped her eyes, drying her face, "Yeah, I've been here a long time, and not alone, either. People just keep showing up. Children, like us. Batches of three or four at a time."

"You killed them?" Sam scoffed, "All of them?"

"I'm the undefeated heavyweight champ."

Sam watched her in disgust, "Oh, my God."

"Don't think God has much to do with this, Sam."

"How could you?"

"I had no choice. It's me or them. After a while, it was easy. It was even kind of fun. I just stopped fighting it."

"Fighting what?"

"Who we are, Sam. If you'd just quit your hand-wringing and open yourself up, you have no idea what you can do. The learning curve is so fast, it's crazy, the switches that just flip in your brain." She laughed, "I can't believe I started out just having dreams. Do you know what I can do now?"

"Control demons."

"Ah, you are quick on the draw." She put her hands to her head, "Yeah, I'm sorry, Sam, but it's over."

The cloud of black smoke returned to the window as Sam readied his iron bar. Just as it was about to enter, Jake came from behind AVA and twisted her neck, killing her instantly. The demonic smoke left the window and disappeared.

Outside, near the edge of the woods, Angel, Bobby and Dean pulled up in the Impala.

"Well…" Bobby sighed as they got out and walked back to the trunk to retrieve guns, "It looks like the rest of the way's on foot."

Dean cocked his, "Let's go."

Back at the building, Sam and Jake left and headed outside.

Sam led, "I think we can make it out of here now."

"But the Acheri demon…"

"No, no, no. Ava was summoning it, controlling it. It shouldn't come back now that she's dead. We gotta go."

"Not 'we', Sam. Only one of us is getting out of here." He frowned grimly, "I- I'm sorry."

Sam swung around, "What?"

"I had a vision. That Yellow-Eyed Demon or whatever it was, he talked to me. He told me how it was."

"No, Jake, listen. You can't listen to him."

"Sam, he's not letting us go. Only one. Now, if we don't play along, he'll kill us both. I-I like you, man. I do, but do the math here. What good's it do for both of us to die? I can get out of here. I get close to the demon, I can kill the bastard."

"You come with me, we can kill him together."

He shook his head, "How do I know you won't turn on me?"

"I won't."

"I don't know that."

"Okay, look." Sam took out his knife, showed it to Jake, and placed it on the ground, "Just come with me, Jake. Don't do this. Don't play into what it wants." After a pause, Jake placed his weapon on the ground as well and Sam sighed in relief, "Okay."

Suddenly, Jake punched him. With his super-strength, Sam went flying across the field and crashed onto the ground. Jake approached, kicking down the fence and leaning over Sam menacingly.
