I think part of what will help is that they can’t kill Regina or the curse will never be broken. I wonder which way they will go with Emma, will Regina want to kill her so they can return to the Enchanted Forest now that everyone’s memories are restored or will Regina want to continue to be in the real world. I don’t know.
Rumpel has the Bae thing, but he only uses his power to do something he wants, so he will only come into play when he wants something to do with Bae or Belle, so his power is less of an issue.
Though if Rumpel decides he wants to kill Regina but Emma, Snow, and Charming don’t want that to happen because they are still trying to return to the Enchanted Forest then Emma, Snow and Charming may decide to protect Regina. This is all dependent on whether or not people actually have magic or can use it and how that all works though. People like Regina and Rumpel weren’t born with magic, they obtained it, so there still may be some issue with that. And the bottle of love was made from Emma’s hair so that may make her have some sort of active magical power or it may just make her passively magic or it could make it so that no one elses magic works against her. We will see.
There are a lot of ways they could go. The problem with the state of being of the characters, living in a fairly peaceful setting for so long, is that everyone is not quite themselves anymore. They are going to be somewhere in between the two people because it seems like they still have both memories.
