If everyone suddenly remembers at one time I don’t think it will be a big deal – it will be kind of like FTL has just moved to a new location. But the interesting thing will be if people start to remember one by one – that could have some interesting consequences . . . kind of like how Gold beat Moe French with a cane. Moe has no idea what Gold is talking about or why he is getting beat with a cane – it would have been a very different scenario if he had remembered that he had a daughter (assuming of course that someone let him know that he supposedly locked her in a tower and torchered her) that had chosen to live with Rumple.
You bring up a good point about Henry. Where does he fit into all of this once everyone remembers? I will be interested to see how they handle that situation. As a stepmom I have issues with how Disney always makes us out to be evil and hate our stepkids. But this whole adoptive mother as evil and birth mother as savior is a bit much for me. Once everyone remembers are they suddenly going to have Henry be “rescued” from his evil adoptive mother – the woman who has raised him from infancy, and then given lovingly back to his biological mother – the woman who gave birth to him in a prison, gave him up for adoption, and then impulsively decided to stay in his town after he tracked her down on the internet??? That’s kind of weird to me. Regina is Henry’s mother and that won’t change even if everyone remembers who they are.
