A/N: Chapter 4…finally! I've been drafting this chapter, trying to figure out where to go from here, now that Dean has blindly shot his brother.. thank you for the awesome reviews, and all the favorites/story alerts! It makes me feel good to know that someone is reading my work and enjoying it.

The next hour was touch and go for Sam. Dean had gotten him into the house and onto the couch, and Bobby took over the bullet extraction. Lucky for Sam, the bullet had only penetrated his shoulder. Bobby had the bullet out and the shoulder stitched and bandaged in a half hour.

Dean sat himself at the table and replayed the argument in his head.
"What the hell, Dean!" Sam shouted from somewhere to Dean's right. "Didn't I tell you not to shoot that thing without me?"
"When the hell did you become Dad? I'm not a kid, Sam. I know how to use this thing."
"Not blind, you're not." Sam grabbed at Dean's wrist and tried to take the gun from him. Dean pulled back, trying to escape his brother's grip. He brought his other fist to Sam's face, and he knew he'd hit him when he heard Sam shout in pain. The grip on his wrist was released, but Sam wasn't down for long. Dean suddenly felt Sam's hands on his arm again, and as he yanked his hand away, the gun went off. Silence was all he heard next, and Sam hitting the ground. Minutes later, he heard Bobby's voice in the distance.

He could hear his brother's grumble, and he knew his brother was conscious and alert. The sound of clothing told him Sam was putting his shirt back on.

"Sam – "

"What the hell is wrong with you, Dean? You fucking shot me!"

"It was an accident, Sam! If you hadn't tried to bum rush me while I had a loaded weapon in my hand –"

"That's a load of crap, Dean! You get the shit smacked out of you by angry spirits every day, and your finger never slips from that trigger."

"Are you saying I shot you on purpose?"

The phrase brought an instant silence into the room. Sam wasn't sure what to say. He was saved from a rebuttal as Cas popped into the room.

"What did you find out?" Bobby asked immediately.

"There were angels in the area at the time you two were attacked. None of them are in tuned to Zachariah's location. He's hiding himself."

"That's just peachy," Dean said as he got up and made his way to the kitchen. He didn't need to feel his way around much anymore. He went to the fridge with ease and took out a beer for himself. "So what do we do now? We can't find Zack, and I'm still blind."

"Come and sit down, Dean. I have an idea."

Dean took his seat at the table, and Cas was next to him in the blink of an eye. He put a hand on Dean's shoulder, and another on his chest. The next thing Dean felt was an excruciating pain in his chest. The bastard was reading him. It was over in 30 seconds, but it seemed like 30 minutes to Dean.

"Zachariah did not cause Dean's blindness," Castiel finally said. "I don't think it was an angel at all."

"One of the demons that attacked us?" Sam asked.

"No, something much more powerful. There are very few spells that inflict blindness, and even fewer reversals. It would take a powerful demon to find and execute such a spell."

"You think a demon did this?" Dean asked, still holding his chest, trying to make the residual pain go away. "Why would there have been a white light?"

"The demon blinded you. I believe an angel pulled you out of the fight in order to preserve your lives. You can't be Michael and Lucifer's vessels if you're dead."

"Yeah, well nice of your angel buddy to fix me before he left," Dean grumbled. "So how do we find this demon?"

"I don't know," Bobby answered. "I'm gonna start researching every curse and spell known to man. There's gotta be a reversal somewhere."

Sam got up and grabbed a book. "I'll help you out."

Dean got up and sat down on the couch, feeling completely useless. If he tried to go outside and practice shooting again, Sam might tackle him like a linebacker again. He honestly didn't care. He had to do something. Sitting is counterproductive. He'd always embraced that philosophy. Picking up his .45 pistol from the table, he headed for the door.

Sam saw his brother leave, and was tempted to stop him, but a glare from Bobby made him think otherwise.

"Let him go, Sam. He needs some time to deal with this on his own." Bobby said sternly. "Plus, I don't want you two shooting each other In my yard anymore, clear?"

Sam nodded and looked down at his book again. Cas decided he'd do more recon, and disappeared as quickly as he had come. It was going to be a long day.
