They can’t kill Henry. Emma would have no reason to stay and help if Henry is gone and the character would never be the same. I still say that is a show ender. And didn’t Ginnifer Goodwin just say that the show will make you want to throw stuff at the tv and not that a death will make you want to do that?
She would if she now realizes that she has to save her parents and the rest of the town? It looks like she’s gonna start believing so she’ll know the truth about that. I’m just connecting dots with what Ginnifer said I’m sure someone from the main cast dying will have that effect!
