The writers can only do the whole “The Charmigns vs. Regina” dance for so long. The idea of the final battle being about someone’s hatred for a little girl would be ridiculous and downright laughable. I seriously hope this isn’t where the writers are going. That would be a bit of a letdown. The show needs to go out on a BANG.
I’m sure it will. Snow and Charming aren’t the only two people Regina has made enemies of, she’s made herself public enemy #1 in multiple worlds. There’s plenty of hate to go around!
