I’m not faulting Henry for wanting to spend time with his family, that’s completely understandable, it’s the way he went about it. One of Regina’s fears since Emma came to Storybrooke was that she would take Henry away from her. Now that Emma has returned, it looks like that fear is coming true. Regina had no place in going to dinner with Henry and the Charmings, everyone knew that, but Henry should have at least offered. Regina would’ve probably refused anyway but there is a difference between declining an invitation and being left out.
It’s the look on Regina’s face that makes me feel sorry for her. Henry, why couldn’t you just invite her and let her decline?
