Castiel was grateful for how Meg was accepting of his current state as a human. It would have been difficult for him to adjust if he didn't have that support and while the Winchesters were his friends and Sam offered to help, he couldn't be certain how Dean would have reacted in this situation, had he needed more help from either of them. Meg, at least, didn't make him feel like his worth in life was less, simply because he didn't have his abilities that came from having his grace. He hadn't thought of the ways he should learn to protect himself now that he no longer had the ability to smite, which put him at the level that most ordinary humans were at. He'd have to learn to hold his own, if things were to go awry here in Oakdell.

It had been terribly interesting for the better part of a minute or two, thanks to not really knowing how to answer her question. "I know that it is difficult, these feelings that we have," he admitted, because they were both unaware of how to engage them at first, but were slowly feeling their way through it, as best they could. "I think that it would have hurt. It wasn't pleasant, being apart from you." He might not have been in the state she'd been in when that exile between them finally ended, but he would have easily found himself there if he hadn't the hope he did that he would one day be able to reach her.
