The angel had surely picked up on Jason's awkwardness, because he leaned back a little once the young man started feeding the dogs, his expression relaxing back into one of quiet acceptance. Very nearly a blank expression, save for the gentle nature it held. He was an Angel of the Lord, they didn't have too many default settings, but luckily this was one of them.
"Well, I can see that your soul hasn't passed over. You haven't been to Heaven, or to Hell. Souls don't remain in bodies, they either cross over to where they belong or they become trapped somewhere they don't. It's unlikely you were a ghost, you would probably remember something of that. It's more likely that you were simply never collected by a reaper, for whatever reason, and that instead of manifesting into a ghost due to unfinished business, your soul just lingered in that place between." Cas took up his coffee again, having realized he hadn't touched it in some time, and he took a sip. Yes, see? He was normal. Nothing to see here.
"You should eat." It was the calm recommendation from the blue-eyed brunette, who lowered his coffee a minute later. Sure, he wasn't eating, but he didn't eat. Not that Jason knew it.
Sure, he'd told Jay he was an angel once, but it wasn't as if the young man had believed it.
Most people didn't. Castiel couldn't really blame them.. modern day was hard on religion. All those evangelicals, spreading their poison and claiming it was God's work. Where were the devout to learn?
