If properly done, this season could end up being the most intense season of the show. Till now we have had all those characters fighting against one or two Big Bads and their associates but what if this new Big Bad is able to turn them against each other? While I don't think this is the battle Rumple was talking about in the Pilot, I agree with the rest of your theory.
