to answer your questions as to what happened between Emma and Snow, the ET spoiler this morning said that Charming and Snow have a dark secret that they are keeping in relation to Emma, that pre-dates her birth so maybe that's what could have caused a mini fallout between Emma and Snow.
Yep, this is my thought too, altough I think my real question is what dark secret that predates Emma’s birth can cause that she won’t want to say goodbye to her mother. That two will be the death of me I swear. I want them to reconcile, to get to the deep of their problems and then forgive and move on. I don’t care if they are shouting at each other for one episode or two, just put those feelings into the air so they are not poisoning them anymore. As they are, they are breaking my heart constantly.
