"I'm the only angel on the block," Castiel pointed out, until he thought the better of it. "Actually, I'm not even an angel any longer. I'm just like all the other humans present here in Oakdell. You are, in fact, rubbing shoulders with one when you are around me, Meg." He thought it was worth noting, not because the references to him being an angel made him uncomfortable or angry, because they didn't. They might create a sense of longing within him, as he was reminded of his grace and how he wished he was reunited with it, to have that piece of him back, but it didn't create a true amount of despair because of the reminder. Although, he supposed it would be a similar issue if Meg were suddenly to become human permanently and her demonic nature was stripped away from her.
A beat passed and he was eying the food on the plate before him, taking his knife and fork in hand because it really did smell quite good. It warmed his heart, knowing that Meg went through all of this trouble when she didn't require food. He was the one here who truly needed this sustenance and yet, she went through the motions to set the table for them both. For him, that meant a great deal because she was willing to do these human things with him, things she didn't truly require doing, because it meant they did them together. The more time he had with Meg, he thought of as well spent and wanted more of that time if he could have it.
