AN: My first venture into the Supernatural Fandom to fix a little (okay not so little) thing that pissed me off.
Something Distant
Sam had been more than ready to deal with Castiel as a human. Maybe "deal" was not the correct term. There really wasn't a right term for it, Cas was family after all. After tracking the ex-angel, and once they finally got Cas settled in the bunker, Sam realized that perhaps, there would not be so much dealing, as there would be guiding when it came to humanity. Cas had just survived quite some time on the streets as a hunted ex-angel, and he'd managed well. Perhaps the only true guiding needed would hopefully be towards someone a lot safer than a reaper.
It was only a few minutes after that enlightening conversation regarding April that he looked up and saw Dean walking out of the room. Shortly thereafter Castiel threw the burrito wrapper out in the nearest trash and left right out the front door. Poor guy was probably going for a walk or some air, he could relate. Sometimes being cooped up in the bunker seemed unnatural. Sam looked forward to the idea that maybe when Cas was back up to 100% then maybe they could be running buddies.
Sam's thoughts were broken then Dean came back with a duffel bag,
"Hey Sammy, where'd Cas go?"
"Outside, probably for a walk?"
"Crap" A look of what could be quantified as a flash of terror gripped his brother's eyes as he ran up the stairs, duffel in hand.
"Dean, what's up?" When his brother didn't answer, he took the stairs two at a time, but Dean was already in the Impala, tearing off into the street. Sam barely noticed it at the time, but the sun was a lot lower than it should be for that time of day.
Sam called his brother and learned (again) that Cas was almost worse than Dean when it came to being overprotective. Leaving the bunker without saying goodbye even, just to protect the boys from the angels after him… It wasn't right. Nonetheless after an hour of searching the nearest roadways Dean came back to the bunker, duffel bag still in hand.
It wasn't until several weeks later that they heard from Cas again. Kevin understood the gist of what had happened between the boys and the ex-angel, but he knew this was Dean just taking the only available chance to get out of research. Sam knew that wasn't the only reason Dean was leaving after that call. Dean denied that he'd be going to see Cas per the ex-angels wishes, but Sam knew that duffel bag was in the trunk of the impala. He'd bet money that Dean would find a way to get that duffel to him.
When dean came back after a successful hunt dealing with the very thing Cas was trying to keep away from the Winchesters, Sam checked the trunk of the impala. The duffel bag was gone. Sam smiled, although Cas had opted to still keep his distance, he knew that he and Dean would be a little more a peace.
