"It's good having you around." Dean admitted, giving a half shrug like it didn't mean that much. It probably shouldn't mean as much to him as it did. Even if Castiel was just sitting there, being quiet...staring. It was just what Cas did. The fact that he was there, and alive, was a lot to Dean. He definitely didn't believe in most of the crap people might have tried to name whatever was happening, but he just hoped it wasn't some kind of mistake or random coincidence.
He watched as Cas lowered himself, unable to help but smile at how stiff he seemed. It was endearing, how out of place the angel could seem when Dean had seen on plenty of occasions how effortlessly he moved in a fight. He looked back up from where he'd been staring at Castiel's coat, one of the buttons actually down near his hip, before shrugging. "Not yet." He did push his thoughts away again, because he didn't want to try and figure out what about being in his bedroom was better than skunks to an angel.
"Lose the coat. And no shoes in bed." He gave a little nod, trying to give Castiel a bit of a stern look, like it was clearly not negotiable as he shifted to slide himself down more on the bed. "If you're staying..." He started, then just gave the bed a pat before closing his eyes just so he could roll them at himself without Cas thinking he did something. He had a feeling he was going to end up questioning his sanity before the night was done. "You might as well make yourself comfortable. No hogging the blanket either." Moving again, Dean just tugged at the covers, so he could shift on his side and properly lay, tucking an arm under his pillow. "What do you normally do at night, anyway?"
