Cas supposed it was something akin to Bobby Singer's house. Having never lived in a place other than Heaven, he didn't quite understand.
He shoved his hands into the pockets of his coat, examining it. It didn't seem as if it were the best place for survival. There was no place to store food or much of a shelter should it rain. These were not needs of his own, but he'd taken them into account for Sam and Dean's sake.
"How did you survive?" Castiel asked curiously. "This...place seems to lack basic human needs."
