"Brace yourselves. He'll be here. I can feel it." John Winchester advised his boys, bringing the gun closer to his face. Dean and Sam trailed behind him, eyes alert. They followed a few steps behind him, glancing around the warehouse. The demon could be anywhere. Lurking around the ancient-looking boxes, hiding in the darkness of the shadows…

Sam swallowed nervously, doing a once-over on the place. Anywhere, it could be anywhere. God, this whole thing was so nerve-racking. Dean turned around.

"Sam, you okay? You look kinda pale." he noted, stopping for a moment.

"Nah, I'm fine. Just… nothing."

Dean doesn't look very reassured, but he faced forward and continued to walk. A moment of silence passed. The only noise heard was Sam's quiet breathing. His brother cleared his throat.

"Dad. You sure he's here?" Dean hesitantly questioned. John nodded and kept moving forward, only occasionally glancing around. After another ten minutes of exploring the warehouse, Dean stopped.

"Dad."

John Winchester didn't stop. He kept walking, gun at the ready. Dean stepped forward, hand on John's shoulder. He spun his father around to look at him. That's when he realised.

"Sam… Sam! It's not him! That's not Dad!" Dean said, voice rising.

Sam stopped. "What? Of course it is." John nodded.

"Yeah, don't argue with me. Let's keep moving." Before he could turn around, Dean grabbed him forcibly and shoved him into the nearest wall.

"Dean!" Sam yelled, rushing next to his brother.

"You listen to me. You. Are. Not. My. Dad. Now, I want you to tell me just who the hell you are before I send you back to where you came from." Dean growled, voice low. John rolled his eyes.

"Obviously you don't know who you're messing with."

With a flick of his hand, Dean's body went airborne, flying across the room like a rag doll. He smashed into some boxes and Sam heard a sickening smackas Dean's head made contact with something metal. Sam jumped back, aghast. "DEAN!" he yelled, running over to help his brother.

He was crumpled on the floor, a nasty cut on his forehead. A stream of blood trickled down his face. Sam gulped. The demon strolled toward them both. Sam turned towards him.

"Get away from him."

It smirked.

"You are so cute. Really, sticking up for you brother like that."

Sam shakily reached for his gun. The demon shook its head.

"Ah, I wouldn't do that. You shoot me, you're shooting your dad as well. But then again, go ahead. Who care about him?"

Dean groaned and turned a light shade of green. Sam's hand trembled.

"What do you want?" he asked, trying to sound brave.

"Oh, Sammy." John sneered. "I just want to torture you to no end." He laughed.

"Please. Leave Dean and Dad alone. I'll do anything. What do you want, really?"

The demon scratched its head, pretending to think.

"What? My life, my soul?"

A pause.

"Your sight."

Sam blinked in confusion. "My sight? You can do that?"

"Haven't you ever seen The Little Mermaid? If Ursula can take her voice, I can take your sense of sight. Deal or no deal."

"Sammy." Dean croaked. "Don't do it. It's not—" he gagged, almost getting sick. "worth it."

"I accept. Now get the hell out of my dad."

John grinned. "I knew you'd see some sense. Oh, excuse the pun, Sammy."

"Don't call me Sammy." he snarled.

With a cloud of black smoke, the demon exited traditionally through John's mouth. The brothers' father collapsed to the floor with them, choking and coughing. In an instant, Sam's world dissolved to black.

John recovered and gripped Sam tight. "Sam? Look at me!"

Sam Winchester blinked and stared straight ahead. "I can't. I can't see."

"SAM! Yes, yes you can! I know you can. Look at me." John experimentally waved his hands in front of his son's face. He didn't even flinch.

"Dad, we have to take care of Dean. Let's go."

Sam unsteadily stood up, only to sway and pass out on the floor.
