New story yaay! This takes place during the episode 'Slumber Party' and, well, I borrowed some things from the episode (like the characters and some dialogue) but I've changed like nearly every aspect of the story. It's a cross-over with Wicked the Musical so it will feature some of the Wicked characters. You don't really need to know Wicked to be able to follow it, since Charlie has to explain most to Sam and Dean anyway ;)

Chapter 1

It was already late when Dean entered the bunker. He'd just dropped off Kevin to take a little holiday from the agonizing translation of the tablet.

Poor boy.

He opened the bunker door and saw Sam sitting downstairs at the table, doing some research.

He looked up when he heard the door slam shut. "Hey." He said, putting his pen down. "How'd it go with Kevin?"

"Oh, that little nerd is in a lovely warded hotel room in Branson." Dean smirked and walked down the stairs. "He's got about 48 hours of pay-per-porn and Kenny Rogers ahead of him."

"How's he feeling?" Sam asked.

"Well, he stared at the Angel tablet and repeated the word "falafel" for the entire ride." He sighed. "Kid's cracked. I'm hoping this break will clear his head."

Sam tiredly stared at the papers in front of him.

"You know, after everything that happened," Dean said, opening his plastic bag. "I figured we could use a little break ourselves, so I, uh, picked you up season one "Game of Thrones." Figured we'd get a little takeout."

Dean smiled. He was such a fantastic big brother. Sam laughed too when he heard the title of the series, but shook his head.

"All right. Well, first, I think I might have found a way to help Cas."

Dean looked up, suddenly concerned. "Did you talk to him?"

"No?" Sam frowned. "And, by the way, I still don't understand why he left in the first place. I mean, the bunker is the safest place for him. Bartholomew and, and who knows how many other angels are out there, gunning for him."

"Hey, look, nobody wants him here more than I do, okay?" Dean sighed, taking off his jacket. "But, uh, he felt like he'd bring trouble down on us, so he had to split. But if you got a way to help him, I'm all ears."

"All right." Sam pointed to the table. "So, Kevin said the table lit up like a Christmas tree when the Angels fell, right?"

"So?" Dean crossed his arms.

"So, it turns out each light was where a cluster of Angels fell." Sam said. "So I'm thinking; maybe there's some way to hot-wire this, make it track them. That way, we could help Cas steer clear of danger."

"This was...your idea?" Dean frowned.

Sam looked around, slightly amused. "Do you see anybody else in here?"

Dean immediately discarded his question, steering clear of the subject 'Ezekiel'. "So, how would it work?"

"Oh, no idea." Sam shrugged. "See, at first, I thought the table was the computer, but it's not. It turns out it's just part of it. But I did find these cables underneath, and I followed them. You're never gonna believe what I found."

Sam got up and walked down the corridor, to a room full of electrical panels, shelves and a very large, old computer.

"Voilà." Sam switched on the lights.

Dean looked around him, a little confused. "This is a computer?"

"Yeah" Sam nodded, "or it was in 1951, when it was installed. Now, here's the crazy thing. It's not plugged in to anything. I mean, I have no idea what's making this thing work."

They walked around it and Dean placed his hand on the back of it. "It's warm here."

He looked around and saw a flat screwdriver on the shelf behind him. Grabbing it, he inserted it under the back panel and tried to jimmy it open. When it didn't give, Dean pulled harder and the panel suddenly popped off, sending him stumbling backwards against a shelf.

"Got it." He got back up, smiling.

Behind the panel, there were a lot of wires and bulbs and other complication Sam-stuff.

"Huh." Sam said.

Okay, not Sam-stuff then. Charlie-stuff.

"Well, that looks simple." Dean said sarcastically, "Does it come with a manual?"

"Nothing in the archives, and I obviously couldn't find anything like it online," Sam shrugged. "not to mention I'm pretty sure that the Men of Letters doesn't exactly have I.T. support anymore, either."

"I think I know somebody who could help us." Dean started to get up, "Come on."

They left the room and Sam turned off the lights behind him.

"Who are you gonna call, Dean?"

"Ghostbusters!" Dean grinned at his own joke as he put the phone to his ear.

"Dude…" Sam said, but Dean interrupted him.

"Charlie! Hey! … Yes, fantastic! What about you? … Yes, about that, where are you?"

…

Fourteen hours later, Sam entered the bunker with their special guest.

Dean smiled at Charlie, who was walking down the stairs. "Hey. Thanks for coming."

She hugged him briefly.

"Not a problem," She smiled. "Especially since I got fired last week."

"Hey, what?" Sam frowned as he put her bag down on the table. "What happened?"

"Turns out the company I work for was outsourcing to child labor," Charlie shrugged. "So I took a big Wiki leak all over that. And, yeah. It's cool, though. It's given me more time to focus on my hobbies like larping, macramé, and…" She hesitated a bit too long for Dean's liking. "Hunting."

Dean frowned. "Excuse me?"

"Okay." Charlie raised her hands in defense. "It was just a couple little cases. I took down a teenage vampire and a ghost," she smiled, as if that would make it better, "which sounds like a Y.A. novel if you say it out loud."

Dean frowned harder, to make sure Charlie would get the message about what he thought about her hunting.

"Charlie, how'd it go?" Sam asked, concerned.

"It was, uh... It was intense." She grinned. "But I kind of wish hunting was more, magical, you know?"

Dean rolled his eyes. Sam just looked even more confused.

"Never mind." Charlie said quick, discarding the subject 'hunting'. "So, where is this Commodore 64 of yours?"

"Follow me," Sam said, leading Charlie the same way he lead Dean yesterday, to the old computer room.

"Sweet Ada Lovelace." Charlie said when Sam turned on the lights. She dove behind the console. "This thing belongs in a museum. I mean, it's got encryption software. It seems to be powered by something magical…"

"Skip to the end." Dean said. He was still annoyed with her.

"It's kind of an alarm system. Global badness? It freaks. This computer is what locked this place down." Her head popped up from behind it.

"Can we use it to track Angels?" Sam asked.

Charlie looked to Dean to see if Sam was serious, but when Dean nodded, she snapped her fingers.

"All right. Let me see what I can do." Charlie ducked down behind the console again. "Sam, get me my laptop, please."

"Uhm- yeah- sure," Sam said, and he left the room.

"Do you want, like, a drink or something?" Dean asked, uncomfortable.

"If you dare to bring liquid anywhere near this beauty, I will break your pinkie." Charlie mumbled, with something in her mouth. "Bottled water please."

Dean huffed and walked back to the kitchen to fetch some bottled water. Did they even have bottled water?

Dean opened the fridge, the only bottles they had were beer bottles.

"What are you looking for?" Sam asked.

"Bottled water." Dean replied. "Why would you buy water in a bottle when you can drink it from the tap?"

"Because the bottled water is cleaner than tap water, Dean." Sam said. He pushed him out of the way and opened the fruit container, which was filled with apples, pears and bottles of water.

This all much to Dean's surprise.

"Why do we have all this?" He asked Sam.

"Because my body does not comply at all to your vast diet of burgers, chips and junk-food, Dean. Why aren't you fat?"

Dean grinned. "You could say, it's not… natural."

"Yeah," Sam shook his head. "I'm… uhm, gonna get this to Charlie."

He walked off.

Dean huffed. "Because my body does not comply at all to your vast diet of burgers, chips and junk-food, Dean." He repeated in a high voice. Sam could be such a wuss. "Because I am Sam Winchester and I work out regularly."

He grabbed a beer and pulled the cap off, taking a long swig.

"DEAN!?" Sam called. By the sound of his voice, it wasn't the first time.

"WHAT?" Dean yelled back.

"DEAN!?" Again, and he sounded panicked.

"SAM?" Dean put his beer down on the counter and took off with a sprint to the computer room, where Charlie was lying on the floor with something green wrapped around her ankle, and Sam pulling on it.

"What the Hell?" Dean swore. He pulled Ruby's knife from his boot and started hacking into the green rope, which ran back to a jar lying on the ground. He slashed it, and out of both ends came green smoke.

"Gosh that stinks." Charlie said.

Then she fainted.

"Charlie?" Dean said. "Ch-" he looked up at Sam.

"What's… what?"

Then the world went black.

…

When Dean woke up, he was lying very uncomfortable, partially on grass and on brick.

"Are. You. Kidding. Me." Charlie slowly got up. "Are. You. Flipping. Kidding. Me."

"Charlie?" Dean rubbed his head. It was still a little hazy from the green smoke.

"Dean." Charlie helped him up. "I believe I know where we are."

"Where are we then? How do we get back? And most importantly, where is Sam?" Dean looked around him. They were in broad grasslands and there was a large tower in the distance. He reached to check if his weapons were still there. Throwing knife, check. Gun, check. Ruby's knife… he looked around him and saw it lying on the ground. He picked it up. Check.

"We're in Oz!" Charlie gleamed, slapping him with her bag.

"What?" Dean frowned. "No. The smoke got to your head. Let's head to that tower. Either we're dreaming, which is bad, or we've been moved, which is worse. That tower is the only landmark near, and if Sam sees it, he'll go there too. How the Hell did you get your bag?"

"I might not be a lady-lady, but I am still a lady, Dean," She smiled. "No, it was the closest thing to a weapon I had."

She was silent for a second and sat back down again.

"I'm gonna try and pray to Cas." Dean said. "Maybe he can come and fetch us."

He closed his eyes. Cas, pray the lord my soul to keep and come save our asses.

Radio silence. Dean cursed silently.

"OMG, my tablet is still in there." Charlie rumbled in her bag, handing Dean deodorant and mints and a pad until she fished her tablet out. "Thank God, it's not broken." She turned it off. "I have an extra power charger in my bag, but you'll never know."

He hauled Charlie up, laughing, and they started walking on the brick road towards the tower.

"This is Oz, Dean, I am certain." Charlie said, looking around her. "I think that is…"

"Charlie, I think you need to sit down. Why would we be in Oz?" Dean frowned. "Why would Oz even exist?"

"Because…" Charlie shook her head. "I don't know."

"Charlie, what color brick is this road?" Dean asked.

"Grey." Charlie said. "But not all roads in Oz have to be yellow."

"Okay, Charlie, let's just… we'll find out ourselves." Dean kept walking and Charlie followed him.

After a while, Dean broke the silence. "So, uhm, Charlie, what was all that about how hunting isn't magical?"

Charlie shrugged, "Saving people, hunting things, the family business? I am down, but... I was raised on Tolkien, man. I mean, where is all this?" She pointed around her. "Where are my White Walkers and my volcano and magic ring to throw in the damn thing? Where's my quest?"

"Magic, quests, they suck. Trust me. They're all…" Dean was rudely interrupted by something large brushing over his shoulder, flying back over their heads and then landing in front of them.

It was a monkey. With wings.

"Charlie, I've seen some weird things, but this…" Dean frowned.

The Monkey handed him a letter and Dean opened it, and Charlie sank down next to it.

"Hello," She said. "Can you tell us where we are?"

The Monkey frowned. "Oz." it uttered.

"HA!" Charlie yelled, scaring the Monkey away. "I told you…"

"Charlie," Dean said. "You should read this letter. This is extremely weird. Like, weirder than the fact that Oz is a thing."

"What's it?" Charlie got up and pulled Dean's arm down so she could read the letter too. "It's from Sam."

"Dean and Charlie," Dean read. "Don't worry, I am safe. If you landed where Elphaba said you've landed, you should be able to see a tower. I am there. Come quick and be safe. –Sam. This is really weird."

"Look there's a P.S.," Charlie pointed.

"The lady is green, don't make any remarks. Geez, he has so much faith in me." Dean growled.

"If there was a green lady, wouldn't you make remarks?" Charlie said.

"I… shut up." Dean said.

"Also, the lady is green." Charlie said.

"So…?" Dean shrugged. Apart from the fact that she was green, that wasn't all that weird?

"And Sam said Elphaba."

"Charlie get to the point." Dean said.

"This is so cool!" Charlie said, "We're not just in Oz, we're also on our way to Kiamo Ko, in the Vinkus, slightly West from the Emerald City, to go and see Elphaba."

"Who is Elphaba?" Dean asked.

"The Wicked Witch of the West?" Charlie frowned, "Dude, have you never seen Wicked?"

"Oh, I'm sorry, I've been a little too busy preventing Armageddon to go see movies." Dean said.

"It's a musical, but okay then." Charlie waved the letter around. "This is what happens, Elphaba is a green girl who attends Shiz University to receive education, but primarily to take care of her disabled sister, Nessarose…"
