Things used to be a lot simpler. Cas was cas. He looked a certain way and when Dean looked at what he recognized as Cas he could always assume that it was cas. You know, like how your assume everyone else is who they look like? Nowadays, things aren’t so easy. Dean had always kept in the back of his mind that Castiels human form wasn’t actually his own. It was a human, a vessel, that Castiel was hitching a ride in. Dean had actually met that guy. He was a normal bible thumper suburban white dad kinda guy. A little odd, but he was a normal guy. It was actually really weird to see that body, who previously encased an Angel of the lord, act so human and normal.
Since then, Jimmy and Castiel had , apparently, been growing close. Like friends. Like how Adam, the Winchester’s half brother, and Michael, the archangel, were. They lived in harmony with each other and gave each other time outside of the inside of their minds. Instead of keeping one or the other trapped inside. They lived with each other. Apparently, Jimmy and Cas decided they’d like to begin doing just that.
The precise moment Dean realized, after years of not seeing Jimmy, that he had reappeared was jarring. Dean was coming to Castiel with some weird joke. Or maybe it was to tell him something he’d seen on TV. Dean didn’t remember.
“Hey, cas!” Dean said as he strode down the short stairs that led to the War Table, where cas sat and ,, was eating? Whatever, cas is a weird dude! Castiel looked up at Dean with big confused eyes.
“So, Your never going to believe this. I-“
“Uhhh dean?” Castiel said, uncharacteristically. His normal monotonous tone of voice was gone and replaced with a more human tone. “Castiel isn’t here right now, it’s Jimmy” Castiel, Jimmy, informed.
“Jimmy..?” Dean questioned and Jimmy nodded his head as he took a bite of the burger he’d made from ingredients he’d found in the kitchen.
“Is cas okay? Did he get hurt?” Dean said, worrying. Last time Jimmy had shown up, it was because Castiel had been dragged back to heaven and had sense beaten into him. If something like that was happening, Dean needed to know so he could save him or ,, stop it. So he could do something. Jimmy looked at him, confused again. But then realization hit him.
“Oh. No no, Castiel is fine! He’s here with me” Jimmy smiled, tapping his head. Dean blinked
“Okay…..” Dean said, confused as hell. “Excuse me for asking but, Why’re you ,,, uhm, here?”
Jimmy took a bite of his burger, set it down and wiped his hands. “Well,” Jimmy said through a full mouth. “Castiel and I are at an agreement. We’re gonna let each other exist at the same time, or something.”
“Or something??” Dean questioned, very confused.
“All I know is castiel wants to share the body. Like uh, those two uh guys. Adam and Um,, Michael? How they lived with eachother? That’s how me ‘n Castiel are gonna be from now on!”
Dean nodded, taking in this new information. That meant Cas was gonna be out of commission more than not. That also meant he’d have to deal with the annoying bible thumper and the annoying oblivious Angel in equal time.
“All I know,” Jimmy said, picking his food back up, “is I get to stretch my legs. And eat!” Jimmy exclaimed as he happily bit into his burger.

It took a while to get used to and the two definitely took advantage of being able to just leave and not be found. In the middle of an argument, Castiel would just go into the inner body and Jimmy would appear. It was awkward.
“CAS.” Dean yelled after him. Castiel just grunted. “You can’t fucking do that! You almost got yourself hurt. It could’ve been even worse if you played it any wrongly.”
Castiel didn’t reply, and kept his back to Dean. But had stopped in his tracks. “Cas, Cas look at me-“ Dean said, grabbing Castiels shoulder to get him to face him.
Dean could tell when it was Jimmy or Cas nowadays. The innocent, human look of Jimmy showed all over his face and Dean sighed. “Cas gone?”
Jimmy nodded.
The two were inseparable. I mean, not like they could separate exactly. But in a ‘they are very close friends’ way. They loved each other like family. Like how Dean loved Sam. Jimmy and Cas opted to protecting each other when they could. If, when Jimmy was out and a monster attacked, Castiel would reveal himself quickly to kill them and then retreat.
If, when Castiel was being yelled at by dean, (which was often lately, with all the tension of the end of the world) Jimmy would reveal himself and scold Dean about hurting Castiels feelings. Saying something along the lines of, ‘he isn’t yours to destroy when your too scared to face the truth you keep secret’ as if Jimmy knew something Castiel and maybe even Dean didn’t know yet.

One day, dean asked Castiel a question when he was revealing himself.
“Do you and Jimmy talk directly ever? Is that possible?” He had said.
“Yes, we do. When one of us is out, we are able to send messages to each other. It’s more difficult for Jimmy, as he is human. Along with when Jimmy sleeps, we can communicate and see each other”
“Does he see you as himself?”
“No, he sees me as a ball of light. It’s an easy form and he doesn’t seem to mind. Sometimes I come as an animal, like a bird."
"Huh…” Dean said, thinking about it. “You and Jimmy are pretty close, huh?”
Castiel smiled, “yeah. It’s nice to be that close to someone. Like family. Someone who you’d protect no matter what, and whose protect you too. I have that with you and Jack. Sam too, I believe. The bond between me and Jimmy is different though, I think. Our souls have bonded..”
Dean smiled, he was happy Cas was happy.
