Sam fell asleep in the car.

"What's wrong with him, Bobby?"

"I think maybe too many drugs and too many suggestions. He was brainwashed."

"What do we do?" Dean asked.

"Well, we'll see how deep it goes when the drugs wear off," Bobby said. Bobby didn't want to say anything, but he thought that Sam would still be pretty much scared of them even when the drugs wore off.

"You're right, he'll be fine when the drugs wear off."

Bobby didn't point out that he hadn't said that. Dean didn't need to worry before they found out exactly what they were dealing with.

Sam woke up when they reached Bobby's. "Dean, I've been thinking. I'll do whatever you want me to, if you just won't hurt anybody else."

"What are you talking about?" Dean asked. "I've never hurt anybody."

"You killed all those women in St. Louis," Sam pointed out.

"That was a shape shifter. You know that. He tried to kill you and I shot him."

"There are no such things as shape shifters. You killed those women and then beat me. You told me that you saved me and I believed you because I couldn't believe that you hurt me. I know the truth. The doctor explained everything to me."

Dean and Bobby exchanged a glance. "Sam, maybe we should lock you in the panic room for a couple of days."

"You don't have to worry. I won't leave you again. I won't let another Jessica die."

"Sam, the yellow-eyed demon is dead. And that wasn't your fault."

"There are no demons. I know you and Dad killed her to get me back into the family. I know Dad killed Mom, too."

Dean swore under his breath. Human or not, he wanted to go back and kill that doctor.

"Sam, I didn't kill Jessica."

"Then Dad did."

Dean couldn't help himself. He was frustrated and pissed that Sam could say these things, think these things. He punched Sam. Sam fell back to the ground.

"Dean," Bobby admonished. "This isn't Sam's fault."

"Yeah, nothing is ever his fault, is it?" Dean asked sarcastically. He jumped back in the car and sped off.

"Is he going to go kill someone?" Sam asked from the ground.

"Of course not," Bobby said as gently as he could. "Let's go inside."

Sam went in. Bobby insisted on the panic room. He knew that Sam said he wouldn't leave, but he didn't know where the kid's head was at.

Dean came back the next morning.

"Where you been?" Bobby asked.

"Just driving around. I can't believe I hit him. No wonder he thinks the worst of me," Dean said.

"Let's not start playing the blame game. The doctor filled up his head with a bunch of nonsense and we need to convince him of that," Bobby said.

"How?" Dean asked.

"I don't know. We can't exactly take him on a hunt to show him the monsters. He'd get himself killed."

"Where is he anyway?" Dean asked.

"Panic room."

Sam realized that he shouldn't have agreed to stay. Dean had been able to kill Jessica because, like an idiot, he had told his family exactly where he was going. If he left and stayed hidden, Dean wouldn't be able to hurt anyone because of him. But now he was stuck in this stupid room.

The door opened. "Why don't you come upstairs for breakfast?" Dean suggested.

"OK," Sam said. "Dean, I feel so stupid. I know everything the doctor told me was a lie. I guess the drugs helped to cement it in. I'm sorry I believed that bad stuff about you," Sam said and hung his head down so Dean couldn't see his eyes. He was afraid Dean would know he was lying. On the other hand, it was kind of embarrassing knowing that he was stupid enough to buy all this for so many years.

Dean sighed a breath of relief. "It's OK, Sammy. I'm just glad you're back with us."

Great, now all he had to do was figure out how to get away without drawing suspicion. He followed Dean upstairs.

"Sammy's back," Dean exulted.

"Really?" Bobby asked. That seemed too easy.

"Yeah, I guess I just needed to get all the drugs out of my system for my brain to work right."

"OK,"Bobby said. He'd take easy for once. There was a first time for everything.

SSS

Sam had had a tough time keeping up the charade during breakfast. He hated these men sitting with him, but he couldn't let on to that. They had lied to him his whole life. Used psychological warfare to keep him in line.

After breakfast, Bobby got a call for a tow and he took off.

One down, Sam thought.

"I told Bobby I'd pick some stuff up for him from his supplier while he was gone. Want to come with me?"

"Um, I'm really tired, I think I need to get some more sleep," Sam said.

"OK, I'll be back in a little while," Dean said. He didn't really think anything of it. Sam had slept a lot yesterday and it was probably a result of the drugs. He'd be back to normal in no time.

When Dean had driven away, Sam hotwired one of Bobby's cars and took off in the other direction. He didn't know where he was going, but he knew he had to come up with a plan fast.

SSS

Bobby got back and saw no sign of the boys. He figured Dean had taken Sam with him on his errand. He was glad that Sam was getting out. The fresh air and interaction with other people would do him good. He got to work on the car.

A half hour later, the Impala pulled in. Dean got out by himself.

"Sam isn't with you?" Bobby asked.

"No, he wanted to stay and get some sleep."

"He's not inside," Bobby said.

"Where did he go?" Dean asked.

"I think he played us," Bobby said.

"Any cars missing?" Dean asked.

Bobby went to look. He came back. "Yep. Luckily for us, it's one of the nicer ones."

"Why is that lucky?" Dean asked.

"I put a tracking device in it."

Dean smiled. That was lucky.
