Sam, Castiel, and brainy Dean talked and read about anything they could find related to the subject at hand. They weren't coming up with much. They knew that all parts of Dean's soul would eventually find him since he was like a beacon to them, but they didn't know if the problem would just fix itself or not.

They'd been researching for about an hour when knocking sounded again. Sam and Castiel went to the door while all the Deans waited at the bottom of the stairs. Sam opened the door to reveal another Dean. He was dressed in Dean's normal attire and looked more like what Sam usually saw with Dean. He was smirking and seemed relaxed.

"Hey, Sammy." He walked in and slapped Sam's shoulder. He looked at Castiel as he walked in. "Cas." His tone had changed and Sam saw him look Castiel up and down slowly. Castiel noticed the look, but didn't have time to respond as Sam intercepted him.

"Come with me." He grabbed his arm and took him down the stairs. Dean pouted as he was lead away.

The Dean in glasses rolled his eyes when he saw who it was and turned back to the book he was reading. The smiling Dean gave his usual greeting and tight hug. This Dean returned the hug with a laugh and a loud kiss to his cheek, making smiling Dean giggle.

"God, Dean," Sam stopped next to his brother, "you're so gross."

"Shut up." Dean shoved Sam gently. He was curious who this Dean was but he quickly figured it out when his hands lingered on the other Dean's arms and he looked at Castiel in a way that clearly meant he was checking him out. He groaned internally.

"Don't think I didn't see you, nerd." The newest Dean walked over to the one reading in the library.

"Leave me alone." He didn't even look up from his book.

He leaned over the table and put a hand over the text the other man was reading. Dean looked up over his glasses and glared at him. "I just wanted to say hi."

"I'm sure." He peeled the hand of his book. When he made to put it back, Dean slapped his hand away. "Stop it."

"You stop it." He tried to put his hand in his book again, laughing at the other's frustration.

Dean slammed the book down and stood up. "Go away."

"No." He smiled. "I love it when you get all worked up."

Sam shook his head. "You are so messed up."

Dean ran a hand over his face. "I know." He could hear the pair bickering in the library and he really didn't want to see them start making out, which is where the newest one would probably want to take it.

"Dean," Castiel's voice made him jump, "I think we might want to separate everyone. They don't seem to work well together." He watched the two fighting in the library.

"Yeah, we probably should."

Castiel leaned closer and lowered his voice. "And, the other one keeps hugging me and trying to hold my hand."

They both glanced back at the smiling Dean, who was still standing by the stairs. He waved at them.

"Sorry, Cas. I don't know why they're all so weird."

"They're just you, Dean." Sam laughed as he spoke. "I've seen all of these guys before. Not usually to this extreme, but I've seen all of these personalities come out at one point or another."

"Well, we need to at least separate these two," Dean pointed to the couple now arguing closely in the library, "before they try to kill or kiss each other."

They didn't have much trouble getting the flirty Dean out of the library as he seemed to enjoy being manhandled by the others. He got along well with the happy one so they stuck them near the door and let the other one retreat to a bedroom to continue researching.

Sam and Dean were in the library when they heard one of the Dean's complimenting Castiel.

"I mean, I never thought much of trench coats before but you really pull it off." Dean looked up to see the flirty Dean standing close to Castiel. "And I love this tie." He reached out and took the blue tie in his hands. "It really brings out your eyes."

Dean sighed and made his way to them. He heard Castiel thanking Dean for the compliment. Dean nearly tripped on the steps when the other Dean spoke again.

"Of course, beautiful." Dean saw him wink at Castiel and felt a flare of jealousy, which confused him because it was technically him who said that.

Castiel furrowed his eyebrows and looked at Dean as he approached. Dean laughed and pulled the other Dean's hands away from Castiel's tie. "That's enough, tiger."

"Is it?" He raised his brows at Dean and smiled.

"Yes." He pushed him back and made him sit. "Keep your hands to yourself."

"See, now I'm confused." He smiled again and reached out for the smiling Dean that had been giggling at the table. "Is this still keeping to myself?" He ran a hand through the other Dean's hair, making him squirm and laugh. "Since we're all you, am I allowed to do this?"

"No, stop." Why was he so weird?

"But you said to keep my hands to myself, and he is myself, and so are you." He grinned a toothy grin and continued touching the other Dean.

"He is correct, Dean."

"Cas, don't encourage him." He pointed at the angel and then to the now smug looking Dean. "Stop it. Don't touch anyone. Don't say anything inappropriate to anyone."

"Well," he pulled his hand away from the other Dean, "now we need to discuss what exactly is inappropriate."

"I can't do this." Dean waved his hands and grabbed Castiel, leading him away from the handsy version of himself.

"Oh come on, Dean," the man shouted after them, "don't be like that."

Dean ignored him and led Castiel back to where Sam was trying not to laugh. "Sorry about all this, Cas."

Castiel shook his head. "Don't be. It's interesting to see all these sides of you."

Sam let out a laugh. "Shut up, Sam." Dean smacked him.

"Okay," Sam tried to suppress his laughter. "What are we going to do, Dean? Smart you was right, these guys need constant attention and we don't have any idea what to look for since we don't know what could've done this."

Dean was getting a headache again. He tried to think of something to make all of this easier, but he wasn't coming up with anything. He really didn't have much brain power without the other one.

He sighed when the Deans left at the map table started tickling each other. "Okay, Sam," he turned to face his brother, "you take flirty me, he shouldn't try to molest you." He turned to Castiel. "You go brainstorm with the nerd, try to figure out what could do this and any solutions. I'll deal with happy Magee over there."

They all nodded and moved to their tasks. Sam dragged his Dean away from the other one and took him to a separate room to try and research. Castiel found the room brainy Dean was in and joined him. Dean sighed heavily as he was left alone with his smiling self.

After a few minutes of awkward silence, Dean finally looked at himself. The man was just smiling at him in a very creepy way. He perked up when Dean looked at him. Dean decided to take pity on him. "So, any idea how long the others will take to get here?"

The other man chuckled and shook his head. "No. Probably not long. You're easy for us to find."

"Great."

"Can I help with anything?"

Dean was about to say no but the poor guy looked so eager to please that he couldn't. "Uh, yeah actually," the other man sat up straighter, "I haven't had a chance to clean much in the kitchen lately and…"

"Say no more." The smiling Dean stood. "I can do that. I like cleaning. Well, I like to make you happy and cleaning the kitchen does tend to do that. If only I was a good cook, I would make something too, but I don't really have that capacity to follow recipes well or plan out anything…"

Dean forced a laugh and stood to gently push the babbling man towards the kitchen. "Well, sparky, it ain't gonna clean itself."

He laughed. "You're right. I'll get on that."

He walked away and Dean felt himself relax. He wished that he could stay there and just have something more to drink, but he had to get all this shit fixed first. He made his way to the room Sam was sharing with his counterpart. The whining coming from the room didn't get his hopes up.

Dean peaked his head in. "Everything okay in here?"

Sam stood and moved close to him with a face that screamed for help. "Dean, you need to get him out of here. He's driving me crazy." Dean glanced at the other man as he made squeaking noises with his mouth. "He never shuts up and he keeps telling me about your sex experiences and," Sam closed his eyes and shook his head, "I'm gonna kill him."

The squeaking stopped as the other Dean stood up. "Dean, why did you leave me with Sam? You know he's no fun."

"Well, I had to. I figured you were only safe with a blood relative." The other Dean rolled his eyes at him.

"You're such a party pooper." He stepped closer to the brothers and raised a brow. "Why don't I go help Cas? He wouldn't tell me to shut up."

Sam huffed through his nose and pushed his way out of the room to get some space. Dean put a hand on his counterpart when he made to leave. "No, you stay here. You're not going anywhere near Cas."

The other man smiled. "Oh, so bossy. What's the matter, Dean? You afraid of what I'll do to Cas?" His tongue played along one of his teeth as he smiled again. "There are so many things we want to do to Cas aren't there?"

Dean shook his head. "No, stop." The other man laughed again. "You just stay here and don't talk to anyone or touch anyone."

The man groaned loudly in frustration as Dean closed the door behind him. He moved down the hallway to check on the one version of himself that seemed sane. He knocked lightly as he opened the door.

Castiel and brainy Dean looked up as he entered. They were both looking at a large book and seemed to have been talking in hushed tones before he came in.

"You guys okay?" He looked mostly at Castiel, who seemed perfectly as ease with the other Dean.

"We're fine, Dean." Castiel nodded to him. "We've been going through the possibilities of what could've done this."

"We've narrowed it down to a pissed witch or pissed angel." The other man leaned against the desk in the room and crossed his arms. Dean should wear nicer clothes more often, he looked good.

"There were other possibilities, but we ruled them out as a long shot." Castiel turned to face Dean fully and squinted at him slightly. "Are you alright, Dean?"

"Yeah, I'm fine." He was, considering what was happening. He thought he should probably be freaking out more than he was, but he felt okay.

"You just seem strange." Castiel turned his head as he continued to study Dean.

"Of course he does," the other Dean chimed in, "he's not a complete version of himself. We all seem strange right now."

"Of course." Castiel didn't look convinced but he dropped his gaze.

"Okay, witch or angel. That's awesome." Dean was going to ask about a plan when loud banging echoed from the door. He sighed internally. He was just getting used to the three parts of himself that were there now.

Everyone gathered around the map table as Sam ascended the stairs to find what new Hell was waiting for them now.

When he opened the door, Sam was immediately holding a sobbing version of his brother. A different one had practically thrown him at Sam.

"I found that outside." The Dean that threw the other one looked angry and had his jaw clenched tight. He moved by Sam roughly and made his way down the stairs.

Sam looked down at the man he was holding. It was Dean but he was crying like he'd never seen before and had his arms tight around Sam. He wasn't sure what to do. He managed to walk him down the stairs without too much trouble.

Dean was worried. The version of himself coming down the stairs reminded him too much of the Dean he saw when he was in the 2014 camp. The other one was a crying mess. Dean looked at the man walking towards him. "What did you do to him?" He pointed to the Dean crying as he walked down the stairs with Sam.

"Nothing. I found him outside like that. Apparently the baby was too afraid to knock."

The happy Dean was frowning and ran over to the crying one when Sam got to their level. He immediately hugged him, relieving Sam, and looked at the Dean he'd entered with. "Why are you so mean to him?"

"Why is he such a useless pile of shit?" The angry Dean turned to the pair with a sneer, making them back up slightly. "Who knows what could've followed him here or seen him crying outside like an infant? He's useless and could be putting us in danger."

"Hey," the brainy Dean took a step forward, "don't talk about him like that."

"I'll say whatever I want, nerd."

"We all need to work together right now."

"Please, like we even could." He pointed to the pair that were still clutched together. "Those two are useless in a fight." He pointed to the flirty Dean, who was sitting casually at the table. "He doesn't care about anyone but himself. And you," he pointed to the one in glasses, "take so damn long thinking about shit that we'd probably be killed if we waited for you to think things through."

Brainy Dean laughed. "Please, I've saved your stupid ass more times than you can count."

The room erupted into arguing from all the Deans while Castiel and Sam stood in shock. Young Dean stepped onto the map table and stomped a foot. "EVERYONE SHUT THE FUCK UP!"

Silence followed and everyone looked up at Dean. He couldn't believe what a mess these people were and didn't know how he did anything when they were a part of him.

"Now, no one says a fucking word except for me." Dean looked at everyone slowly. "I want each one of you to pick a room and go into it until Sam, Cas, or myself come to get you. I'm not dealing with this shit from you guys. Get out." He pointed to the hall of open rooms.

Most of them went without fuss, but the hysterical Dean was still crying in happy Dean's arms. Dean hopped off the table and walked over to them. "You two can pick a room together. I don't think you'll cause any trouble."

They both smiled in thanks and started walking away, still clutched together. "By the way," they stopped to look at him, "neither one of you is useless." They smiled again and continued to their room together.

"God, Dean." Sam walked to him slowly.

"I know," Dean pinched the bridge of his nose.

"What's the plan?"

Dean shook his head. He'd had one at some point, but the pounding in his head made him forget. "I don't know. I just needed some quiet." He sat down in the chair beside him and dropped his head on the table. "Sam, do we have any sticky labels anywhere, like for a nametag?" His voice was muffled slightly by the table.

Sam furrowed his brows. "Uh, I'm not sure. Why?"

"Could you check, please?"

Sam glanced at Castiel, who was as confused by the request as him. "Sure. I'll be back." He left the two alone to search for labels.

Castiel stood by the table silently for a moment before sitting in the chair across from Dean. "How are you, Dean?"

Dean huffed a laugh before lifting his head up. "Fantastic."

The angel smiled. "How do you feel?"

"About what?" Dean put his elbows on the table and gently massaged his temples.

"All of this." Castiel waved his hands in the direction of the rooms down the hall.

Dean shrugged. "I don't know."

Castiel leaned over the table slightly, studying Dean's face. "Are you angry, scared, worried…?"

Dean dropped his hands on the table. "What do you want me to say, Cas?"

"What you're feeling."

"I don't know!" Dean raised his voice slightly and covered his face with his hands. He was slightly worried, but not about what had split him apart, about why he didn't seem to feel much right now.

Castiel seemed to sense what he was thinking. "Are you feeling much of anything, or is it more calm and cold?"

Dean looked Castiel in the eye and could tell the angel knew something he didn't. "What's wrong with me?"

"You've had portions of your soul scattered from the core, which is you. They took the emotions from you, mostly. Along with most of your reasoning skills."

"So I'm just a mindless, emotionless, blob?" Dean thought he should be upset by that, but he wasn't.

"No," Castiel gave him a small smile, "you didn't lose everything. It's just dulled for you."

Dean nodded and sat back in his chair. "Do you know what the last part of me is, the thing I'm in danger from?" He watched Castiel for his reaction. The angel's eyes flicked away from him briefly. "I think you do. I know who it is, and the thought of that thing showing up scares me as much as is possible right now."

"It won't kill you, Dean. It would destroy itself in the process."

"I don't think it will care. Besides, I'm not worried about myself. I'm worried about what it could do to Sam or you."

"Don't worry about me. I can handle it." Castiel leaned on the table a little more. "I've dealt with him before, and Sam will be fine."

"You don't know that." Castiel was going to continue but stopped when Sam came into view.

"Well, I didn't find any labels, but we have paper and tape." Sam dropped the items on the table. "Will that work?" Sam had no idea what it would be used for, but he wanted to help.

Dean took a breath and nodded. "Yeah, that'll work." He looked up at his brother. "You got a pen?"
