"You're the first person that I've spent this much time with, when it has nothing to do with trying to stop the Apocalypse or set the world back in balance in some way." He might have been the one who watched over the Winchesters and spent a lot of time doing that for some time now, but he remarkably didn't spend that much time on Earth with them. He was often going between Heaven and Earth, relying on when the Winchesters prayed for him or, if he were already on Earth, when they actually reached him by cell phone. Meg was someone he willingly spent time with, simply because he could and because he wanted to. There was a huge difference, at least in his opinion, in those two situations. "Time with you, it makes me very happy."
Castiel was curious as to why her fingers moved against the blanket covering his hip, mostly because he knew it was an action that could be seen of being out of stress or some other unfavorable reaction. He'd been nearly ready to ask her if she were alright or if something was troubling her, but then she told him that he could touch her if he wanted to. His name, it was almost foreign on her lips, because he rarely heard her call him by his name. His true name. Not the myriad of nicknames that she held for him.
"I wasn't sure," he told her honestly, "Sometimes, I think my presence somehow bothers you or gives you reason to withdraw." Because at times, she put that distance between them or ran off after something happened and that was why he thought his touch could be seen as unwelcome. But, knowing he had permission, and after an intake of breath, something that made him notice that she was that much closer to him, his hand trailed along her arm and came to settle at her hip in a mirror position of how her hand was currently resting on his hip.
