"I'm an actor. I play Dean on TV. None of this is real," Jensen said.

"What?" Sam asked. "You're crazy."

"No, I'm not. The name of the show is Supernatural and the name of this episode is Hollywood Babylon. The P.A. Walter isn't a P.A. at all. He's the original writer. His contract allows him to come on set. He's mad because Marty, the new writer, changed his script and as far as Walter's concerned massacred it. So, he got hold of some amulet and is bringing back ghosts of people who died on set to kill the people he blames for ruining his movie," Jensen explained.

"And you know all this because you read it in a script?" Sam asked.

"Yeah. I also know what the next episode is about. Folsom Prison Blues. We're going to prison to take care of a ghost in a jail. I don't know all the details of that one, though."

Sam tried to think of a way to prove or disprove this crazy story. "How did you switch places with Dean?" he decided to ask.

"No idea," Jensen answered. "Definitely not in the script."

"Do you have the script on you?" Sam asked. If he did, then that would definitely prove his theory. No way Dean could write a TV script. Plus, it might help him figure out what's going on and get Dean back.

"No, sorry."

"What's your name?" Sam asked.

"Jensen Ackles."

Definitely not like the aliases Dean usually came up with.

"So, is there an actor who plays me?" Sam asked.

"Yeah, his name is Jared Padalecki."

"Well, we have to figure this out," Sam said. "Any idea at all what could be causing it?"

"Trickster?" Dean suggested. We met him a few episodes ago, Tall Tales, a haunted campus that turned out not to be haunted."

"Yeah, I remember. But we killed him," Sam said. "I suppose there might be another one."

"No, he didn't die. He played another trick on you. After you guys and Bobby left the building, the trickster that Dean stabbed disappeared when the actual trickster appeared next to him."

"How do you know that?" Sam asked.

"It was in the script," Dean said.

"So, is the trickster in this episode?" Sam asked.

"No," Jensen admitted.

"Maybe we should concentrate on what's in this episode. Could this Walter guy be doing it somehow," Sam asked.

"I don't see why or how," Jensen answered. "Wait a minute. You and Dean found out that they were using real Anokian chants in the film. Do you think they could have chanted something that did this?"

"Could be," Sam said.

"Is there anyway to reverse if they did?" Dean asked.

"We would need to find out the exact spell they said and then say it backwards."

"We'll need to get our hands on the dailies," Jensen said.

"The what?" Sam asked.

"The dailies. They're the CDs of all the footage shot every day. That's how you and Dean found the chants in the first place."

"OK, well how did we get our hands on them," Sam asked. This could be convenient, knowing certain things in advance.

"I'm not sure exactly. I think Dean was flirting with some girl, but I don't remember her name."

"Well, go start flirting," Sam instructed.

"I'm not really good at that," Jensen said hesitantly.

That stopped Sam short. He had just kind of assumed that this Jensen guy was exactly like Dean. "You're an actor, right? Act like you're good at it. Ac t like Dean."

"Right," Jensen said, knowing that's the way he should have been thinking. He would just get into character and find someone who could lay their hands on those dailies.

SSSSSSSSSSSSSSSSS

Dean walked into the trailer behind Sam and watched him walk to the far chair and sit down. A girl started working on his hair. This was beyond crazy.

"Sit down, Jensen," another girl said to him. Why was everybody calling him Jensen?

"My name's Dean," he said.

Jared rolled his eyes. "If this is supposed to be some stupid practical joke, I'm not falling for it," he said.

Why was Sam acting so weird? Maybe that wasn't Sam? Shapeshifter, demon? "Why is she doing your hair for you?" he asked.

"That's her job. She's going to do yours next…as usual," Jared answered. "Now you're going to get your makeup done."

"Nobody's putting makeup on me. I'm not a chick," Dean protested.

"Would you just cut it out? This is stupid and nobody's falling for this 'I'm Dean' crap," Jared said. This was the dumbest practical joke he had ever heard of. Like anybody was going to believe that a TV character came out into the real world. "Dean's not real, you know," he added for good measure.

Dean sat down and picked up what looked like a script. It said Supernatural on top and Hollywood Babylon beneath. He started reading and realized this was a script for what had been happening the last couple of days. The only reasonable explanation—he couldn't believe he was calling this reasonable—was that he was a character in a movie or TV show and had switched places with his actor. He realized immediately that he needed to keep this information to himself or they would ship him off to a loony bin. He would just try to do this for the next couple of days and if he didn't switch back by then, well then he would have to see how to reverse it. Hopefully Sam was working on this problem on the other side.

"OK, I admit it I was just messing with you. What scene are we shooting next again?" he asked the person who must be Sam's actor.

"The grave digging scene," was the answer.

Dean flipped through the script until he found that scene. Seemed simple enough. Walk through the graveyard, he had a couple of lines about a map and Johnny Ramone's grave. Dig a grave, salt and burn the bones. No problem. He concentrated on memorizing the few lines. Suddenly he felt himself be hit by something. He saw a gummy bear falling to the floor. "What the hell?" he asked.

"Gummy wars," the girl doing his makeup said and picked it up off the floor and hurled it back at Sam. No, not Sam. He would definitely need to find out this guy's name. Another gummy bear came sailing over and Dean caught it and threw it back.

"OK, you're done," the girl said. Dean thanked her and felt bad for not knowing her name. He couldn't very well ask, though. The girls switched places and Dean got his hair done. He was done before "Sam" but since he didn't know where he was supposed to go or what he was supposed to do, he just waited.

Soon they were both done and Dean followed "Sam" out and got into the back seat of a truck with him. He wondered where the Impala was but had bigger things to worry about right now. "What are you doing this weekend?"

"I'm not sure," Dean answered, not knowing what the right answer would be. Dean was spared further conversation when they arrived at their destination.
