How It Should've Happened

"Dean You're Staring. Again."

Sam looked between Dean and Cas. They're doing the staring thing again, he thought followed by an involuntary eye roll. "Look, Dean, you can want him dead all you want, but the fact is Lucifer can't be killed, at least not by us, and Gabriel's plan is a good one." Dean stopped looking at Castiel long enough to give his brother a face. 

"I'm just saying that if we don't shank him now, some other hunters are going to have to deal with him in the future, this isn't entirely permanent." he argued. 

"Dean, we don't have another plan. Even if we could kill him, we'd never get close enough to try with any sort of weapon." Castiel remarked. 

"We did with the colt!" Dean pointed out. Castiel gave Dean a look like he was explaining the obvious to a child. 

"I think it's safe to say that opportunity has passed and is not coming back." Dean threw up his hands and opened his mouth to respond. 

"Would you idjits quit bitching?" Bobby exclaimed, cutting Dean off. "We're doing Gabriel's plan and if any of you boys got a problem with it, why don't you march your dumbass out the door and off to find a way to kill Satan yourself." Bobby looked pointedly at Dean and poured himself a drink. Dean fell silent, looking irritated. 

"I'm going to get a beer." he grumbled finally. He stalked off to Bobby's kitchen and began rummaging through the fridge. Sam followed, closing the door between the kitchen and the library. "Sam, I don't have a choice, so you already know I'm on board. Just let me drink in peace, man." He found what he was looking for and shut the fridge, noisily popping the top off his beer. He had just started a long swig when Sam said, 

"What's the deal with you and Cas?" Dean raised an eyebrow. 

"What do you mean?" he dodged. Sam made a face that seemed to say "you know what I mean". "Dude what? There's nothing up with Cas." Dean replied, sipping more of his beer. 

"Right and 'nothing' is why I keep catching you two staring at each other." Sam said sarcastically. 

"What, I'm not allowed to look at the guy now? I'm not staring, Sam, I'm thinking. You should try it sometime." He shook his head lightly and downed the rest of his drink. Sam watched him inhale the alcohol and snorted a laugh. 

"Yeah Dean. Whatever you say." With that, Sam walked out and back to the library. He shut the door behind him, leaving Dean alone. I'm not staring. We were talking. Eye contact is totally normal. At that moment, Castiel opened the door to the kitchen and Dean snapped from his thoughts. 

"Dean, we shouldn't be arguing. Cooperation is very important if this is going to work." Castiel said it matter-of-factly, which Dean noticed was how he said most things. He also noticed how he always emphasized names when he was talking. He wondered briefly if it was strange that he remembered all that before realizing that Cas was looking at him expectantly. 

"What? - Oh yeah you're right I just hate feeling like this is um..." he trailed off as Cas stared at him. His eyes were so blue, it was distracting, like he had just gotten pushed into the ocean and the tide swept him under. 

"Dean." Cas's deep voice pulled him from his train of thought. 

"What?" he said again, looking foolish. 

"You were saying how you hate a feeling but you stopped talking in the middle of a sentence." Castiel was an angel. Literally was the only way he knew how to put things. 

"Right yeah, I just hate leaving things so unresolved." he finished. He tried not to zone out again so he let his eyes wander all over Cas's face. 

"Dean are you alright?" Castiel said seriously. 

"Yeah fine Cas don't worry about it, just thinking." his gaze flicked downward to Cas's lips and then back to his eyes. 

"What are you thinking about?" he questioned. 

"Hmm? Nothing Cas. I'm gunna go see if Bobby needs any help with the lore on Pestilence 'kay?" He gave Cas a pat on the shoulder as he walked by and back to the library. Castiel turned and watched Dean shut the door to the library behind him and only then did he let the worry show on his face. He could feel that something was wrong with Dean and yet he was unsure whether it would upset Dean if he asked again. He'd only been on Earth for a short while and he was finding that humans had many, many emotions. If something was wrong with an angel he did not need to ask what had happened more than once. More often, he didn't have to ask at all. He was finding that with humans, Dean in particular, it was hard to admit problems, or even to know what they were. Since his detachment from most of heaven's power, he had begun feeling emotions. It was dull at first but they had begun to sneak through, causing his thoughts to feel muddled. Just a moment earlier when Dean had been standing in front of him, Castiel had pushed into Dean's thoughts, preferring the shortcut to answers rather than the long way around. It was a bit jarring, since all he could sense was confusion, nothing particularly clear. He had seen the ocean, then Sam talking, then himself and that was when he decided to let Dean be confused awhile before trying again. Castiel wondered about his own feelings for a moment. He was scared mostly, since Lucifer was back. He was sad that he couldn't see his angel brethren. Most prominently of all was the emptiness, like he was missing a part of himself, and he knew it wasn't the angels. He shook these feelings off as he'd seen Dean do countless times and reentered the library. "I'm going out." Dean said shortly, snapping his book shut, "I'm bored and hungry." 

"Gentle with that Dean. You've only been reading for two minutes." Bobby said grumpily. 

"I'll come too." Castiel piped up. 

"You sure Cas? It's not a big deal." Dean said, grabbing his coat, half-expecting him to change his answer. 

"I could use the fresh air. I need to stretch my wings at some point, would that be alright?" he asked. 

"Yeah. Let's get going, I want a burger."
