Sometimes John had had to leave abruptly on a hunting trip when Sam and Dean were kids, more than a few times actually, and he'd just drop the boys off at a half-assed motel, leaving Dean with some cash, a bit of food, and a warning to shoot first, ask questions later, and always look out for Sammy, no matter what. And sometimes John would be gone longer than anticipated and the food and money would have slowly run out. Dean had been too young to work for much of that time so he resorted to shoplifting in order to get food, but what little he could scrounge up, he would always give to Sammy, leaving the barest amount for himself. He knew what being hungry was like.
This was also why Dean later grew up and ate as much as he could manage in one setting because he didn’t know when his next meal might of been, and it was why he got so much pleasure in the food he ate. He was not just gluttonous, but he genuinely thought "This is the best meal ever." And meant it. And he loves pie, not just because his mother Mary would make pie with him, but because it harkened back to a time when he didn’t have to worry about going hungry. When everything was warm and happy and safe, and pie was his most vivid sensory connection to that time.
Dean accepted the food offering with a grunt as Kevin zipped on by to find Sam, still grumbling about angels finding one asian prophet and ringing his scrawny neck. By the time he had carried his prize back to the kitchen to eat it, Kevin had already made his way back, empty handed, and pulled out the chair in front of him.
"You alright, Dean? Did something happen?"
Dean imagined his face must of looked like an open book with illustrations for the easily confused right then, how else could Kevin have been so intuitive? He dropped his pie fork down to the plate and sucked a piece of apple out from between his teeth before he answered, unsure exactly how to explain this to his friend. He had been so caught up in Cas' return earlier that Kevin not being aware hadn't even crossed his mind.
Dean locked eyes with Kevin and it was one of the first times in his long life that his face wasn't lined with a certain hardness. Of course it was still his face, a face that appeared to be sculpted from stone marble but... For some reason it looked softer? Sorrow and joy co-migling, lining every plane and curve of his features. A look that only having just about everyone you cared for, your family, all safe and together could produce.
"Cas is back..." He finally explained, voice low with an undercurrent of something else there. His eyebrows creased his brow, tilting upward. His expression was a full one, one that looked like it had a million things to say. Really, who else in the world could communicate so much with just their eyebrows? It had to be supernatural. Or maybe just an inherently Dean-centric thing. The Vampires from the anne rice novels all had a special skill set, maybe this was just his. Anyone else would probably ask for a return slip if they got that as their super gift, except it worked for Dean. "He is banged up pretty bad, but he is gonna make it." He finished, voice full of concern and relief. "You and me gotta pick up the slack around here, get them on their feet, you understand?" He questioned not really looking for an answer, wrapping his half eaten pie back up and stuffing it in the bag. "Sam can fill you in on the details, and I want you to get a feel for how he's doing. How he's
really doing, you got me?" He again rhetorically asked as he rose from his chair, taking the bag with the uneaten burger and half devoured pie inside in hand, expecting Kevin to understand his true intentions there. "I'm gonna take the burger to Cas, he is probably starving." Dean voiced, making his exit. "Oh and Kev? You ever pull that leaving without telling us where you're going shit, I'll kick your ass." He warned playfully with a wry smile but also in complete seriousness.
After seeing human Cas awake for the first time, Dean could tell Castiel had to of felt as if his body shackled his soul-that he was imprisoned inside a cage of bones now. He knew Cas wanted to let the prisoner trapped inside his chest shriek, dig it’s claws down the throat of reason so it may have the words to explain this but he simply couldn't. After all, being human was being helpless most of the time.
He knew Cas probably wished that he could express to Dean, to Kevin and Sam, that he had a great nothingness that flooded his body when he came into humanity; it sending waves crashing through his trembling fingertips, a hurricane in his mind, a tsunami in his chest. That he thought his winged wounds must have been the worlds failed attempt to dig deep enough to replant his grace back within his body before he hit the ground, clench his newfound mortality in it's fists and rip it from his bones, drain his blood of its contamination, free the life inside by filling it back up with God's divine power. But this was more than he would most likely ever say, had the roles been reversed, Dean would have done the same. He couldn't imagine that kind of pain, always believeing and being one thing with purpose, then suddenly losing all of that.
More than anything he just wanted to be there for Cas as best he could and he couldn't do that if he let slip his own problems so upon finding his closed bedroom door, Dean slipped on his mask. He rarely took it off any more anyways. Almost never. Or was it never, now? It was long past the point where it chafed. There was only numbness where it rubbed against his skin. Dean fancied it had grown into his face, that he couldn't remove it even if he wanted to. The mask was always smiling, always smirking. He chose it for that very reason. People believed what their eyes told them, and a smile of serene confidence set his friends at ease.
"Cas?" He called out, gentlely rapping on the wood with his knuckles before turning the knob and sliding in. "You out yet?"
