I would also see them filming scenes all mix up all to make fans go crazy, if like HJ is right, these scenes would make sense on 620 end , beginning of 621, in fcat we know that RB didn`t filmed for 620, so who knows may they are in deed for that episode, because this final battle, seems no battle at all, nothing flashy happened, they had previous seasons where there was more action than this, if is just Gideon and emma is the same old scenes people saw in S6A, so that is the final battle, against Gideon, not even against Black fairy? There is something strange in all this public scenes.
I don’t think they are filming multiple endings, but i think the idea that this is not the climax is probably true. Something is going to happen with the Black Fairy. That is the thing that is actually going to matter. This is not what is going to matter because Gideon has not been shown to be evil, in my opinion. It almost seems like based on the spoilers. Emma gets stabbed then Gideon does something to her, magic, and she gets up and is alright. Maybe he takes her saviorness like he has been trying to and then she lives again. Then there is going to be whatever happens with the Black Fairy later, maybe. This can’t just be the big battle moment thought, right?
