The flash of skin from Meg, the reminder she was wearing his coat still, it was enough to cause Castiel to look down for a moment, with just the slightest hint of being bashful because he didn't want to ogle her, but he couldn't help it. The attraction was there and the urges of his body were not simply because he was human, but because he wanted her. Not just on the physical level, but in other ways he still had yet to truly understand at the moment. In time, he would understand it and would feel less likely to hold back on her, but until then he'd keep that to himself. Those thoughts and feelings, those urges, would remain under lock and key for now.
He looked to his coat when she tossed it onto the bed, because it was such a part of him that he didn't want to leave it behind. But, on the other hand, he didn't want to leave Meg waiting. She might not lead him along by the hand, but he followed after her not too differently than a puppy ran after someone, hoping they'd slow up so they could catch up. He wasn't nearly as awkward, of course, because he knew how to use his legs but he didn't want her to change her mind and decide to send him home. That was not how he wanted to spend the rest of his evening.
"What are we watching?" He asked, curious as to what was better than the pizza man. Not, of course, did he think that it was anything more that informational and gave him a sort of guide to go off of when it came to some of his interactions with Meg. "Will I ever find out who Clarence is?"
