Dean had been through a lot of crazy stuff. After all hunting was not a normal job. He'd been abducted by fairies, died one hundred times over the course of one Tuesday (though he didn't quite remember that one) and been to an alternate universe where his life was a TV show. He'd seen a lot. He was surprised anything surprised him anymore but, Surprise!, Oz was real and the Wicked Witch was hiding somewhere in the bunker with Dorothy, minus the gingham dress, hot on her trail. And Dean was searching his room for the key to Oz. So yes he was a little surprised.

"You keep your porn meticulously organized but not your…" Charlie scoffed.

"Don't judge me," he said as he sifted through box after box but only came up empty. He knew he'd seen that key before. He remembered finding it when he and Sam had first found the Men of Letters secret hiding place or the batcave as he liked to call it.

"Aha!" he cried. He held up the key just as a cloud of green smoke began to transform itself into the Wicked Witch. She hissed and with a sweep of her hand flung Dean backwards. She began to rub her fingers together as sparks of green electricity gathered in her hands.

"No!" Charlie cried out and sprung towards him. It happened so fast Dean didn't have time to think, only to watch, as the Witch's green lightning reached towards Charlie…and missed. Something had hit her causing her to be a few inches off. The lights flickered as the witch vaporized back into her cloud of smoke and disappeared down a vent. Dean stood up and stared at the object that had hit the witch. It was Dad's journal, which had sat on the desk behind her. Charlie groaned and Dean rushed towards her. She lay against the wall where she had fallen.

"Charlie," he called. She groaned again and opened her eyes with a grimace. He helped her sit up.

"You okay?"

"She missed me." She smiled proudly. Dean stood up and reached out his hand. She grabbed it and with a moan got to her feet.

"Something hit her." Dean said. He searched the room for any sign of her attacker.

"Is it just me or did it drop like ten degrees in here?" Charlie rubbed her hands up and down her arms. Dean breathed out and watched as his breath gathered into a cloud of cold air.

"Sam," he whispered.

"What?"

"Dean!" Cas flew around the corner and into the room. Dorothy ran in behind him.

"Where'd she go?" she asked pushing past him and into the room. Dean gestured with his head towards the gate. Charlie groaned and sat on the bed.

"You okay?" Dean asked. She nodded.

"I think I hit my head pretty hard."

"You stay here with Dorothy. Me and Cas will hunt down the green bitch." Charlie gestured towards the desk with her head.

"Take my gun. I still have one bullet left." The poppy bullets were their last hope although they couldn't do much more than stun the evil bitch. Dean nodded and grabbed the gun off the shelf before running down the hall with Cas on his tail.

Dean didn't remember much after that. He remembered following her through the kitchen- "I just cleaned in here"- and into the library. He remembered shooting the last bullet at her and missing. He remembered her grabbing his head and the next thing he knew he was in a strange garage with his arms around Dorothy's neck and his groin a bit sore. In shock he pulled away and scanned his surroundings.

"Where are we? Is this ours?" Dorothy nodded and Dean smiled.

"Nice," he surveyed the area with a pleased nod before he noticed something missing, "Where's Charlie?"

"She went to take down the Witch with the shoes."

"The what?"

"The shoes." Dean looked at Cas but he looked just as confused although it wasn't a new look for him.

"You didn't go with her?"

"I was a little preoccupied with you two galoots. The witch possessed you."

"Of course she did," Dean muttered as he bounded up the stairs.

"Charlie!" He ran to the room where he'd last left the witch.

"Charlie!" She stood on the railing above his head waving red heels around with a satisfied smirk.

"Ding dong, bitches." Dean rolled his eyes and tried not to show how relieved he felt.

"I don't get it. Is someone at the door?" Dean shook his head and brushed past Cas. As he headed back to the garage he heard Charlie squeak.

"He's just like in the books." Dean rolled his eyes again.

It didn't take long for Dean to move the Impala into her new home.

"Baby looks good in here, huh?" He said when Charlie and Cas joined them. Charlie smiled and motioned her head to the side. They moved to the corner leaving Cas and Dorothy to stare awkwardly at each other.

"So thanks for the slumber party." Dean smiled. "Do you think Sam's a ghost?" Dean's face fell.

"Nah, just a trick of the light... and the air conditioning." Charlie raised her eyebrows clearly not convinced.

"Don't B.S. a . What are you gonna do about it? I mean can ghosts be good?" Dean shook his head.

"I don't know. I just…I still have a lot to figure out."

"Okay but you have explaining to do. When you're ready." Dean nodded and the rejoined the other two.

"Not bad for a bunch of librarians," said Dorothy, "You mind keeping an eye on my bike for me?"

"Yeah, yeah," agreed Dean, "As long as you don't mind me taking it for a spin once in a while." Dorothy smiled.

"Deal." Dean smiled as he surveyed the beautiful bike he'd just been- sorta- given. "Thank you for everything. Now, if you'll excuse me, I have a rebellion to finish." She turned to Charlie. "So, you coming or what?" Charlie's eyes lit up and Dean felt like he'd swallowed the few pieces of his heart that had stayed whole.

"What?" Charlie tried to hide her excitement but it was too obvious. "With you? To Oz?"

"Yeah," answered Dorothy, "You said you were looking for adventure. Well, here it is, Red. Come help me find my damn dog." Charlie turned her bright eyes to Dean and her smile fell. The light in her eyes turned to concern. A part of Dean knew he had to let her go but a part of him held on tight. She couldn't leave him not now, not after all that had happened. Sure he had Cas but Charlie was his little sister, his family. And he didn't have much of that left.

"You have no idea what's in Oz," he argued. "I mean, t-there's flying monkeys, armies of witches. There's all kinds of danger." Her eyes lit up with each danger he listed off. The piece of her that he'd been holding onto was struggling in his grasp, like a bird flying at the bars of its cage. He had lost her already. With a sigh, he gave her a hug and felt her smile. They stood like that for a long time.

"You take care of yourself and if you need anything…" He couldn't get any more words past the tears in his throat. Her head rubbed his shoulder as she nodded.

"Me?" she teased trying to keep her voice light and cheery, "What about you? Will you be okay?" She pulled back and looked at him the tears in her eyes reflecting his own. He tried to smile but it hurt and he pulled her close one more time. Finally, with a light kiss on top of her head he let her go. She gave Cas a quick squeeze and with a huge smile followed Dorothy towards the door. Dean swallowed the tears he'd been choking on and smiled back. Dorothy turned the key and opened the door. Behind it a yellow brick road led the way to what Dean could only assume was the Emerald City. Charlie stepped onto the yellow brick road and looked back with one more bright smile that for a moment made Dean feel a little bit lighter. As the doors began to automatically close behind the two women Dean fought the urge to run down the yellow bricks after them. Then they slammed shut and Dean reopened them to find the paved road leading out of the garage.

"Do you think she'll be back?" But when he turned to ask his question, Cas had disappeared.

Authors Note: Just a small disclaimer, although it may seem like it, I have nothing against Cas, in fact I consider him to be one of the best characters in the whole series but I just feel like in this situation he's a bit oblivious. Not because he's a horrible person but just because he just started being human so he has a lot to learn. I just wanted to let you know so that you guys wouldn't hate me. I also think that Dean probably finds it harder to open up to Cas than to Charlie just because Charlie seems easier to talk too and a little less awkward. That being said I'll certainly miss the little redhead both in this story and in the show. She was one of my absolute favorites. :(
