yea, that was pretty shitty of them. I actually felt bad for her.
meh, I viewed it as her being that typical loser of your group of friends.
You know, 10 of you are hanging out. Two of you decide to go to a club. 7 of the other friends join in, without being asked (because it is understood). And, one person stays behind and cries to themselves about not being invited. Even though in reality, nobody was really invited because it was just a spontaneous event.
I think that she is still having that internal battle between being the evil Regina and being the good Regina that is nothing like her mother. She is letting Rumpelstiltskin get to her for some reason.
