Regina’s immediate reaction to Henry saying that he doesn’t think he’s good enough is to look to Emma as a sort of comfort, almost asking her, with just a look, how they should respond. It’s as if Regina can’t even fathom someone not liking her little prince (and I think she really empathizes with him considering her own self esteem isn’t the highest). And then Emma takes the reins and stays strong for the both of them. It’s such a sweet domestic gesture between the two of them.
