Ok, just a stray thought. Going back to the Author Arc, we saw Isaac manipulate David, Snow, and the Apprentice to bring about the Charmings stealing Maleficent's egg. We saw Isaac do some manipulation of Cruella (giving her animal control magic, and then putting a limit on her ability to kill).

What if... The original timeline was supposed to be Regina going into the Tavern, and Isaac manipulated that in order to "Keep the story interesting"? And if that's the case, maybe Henry, as the next Author, will have the power to correct that, and in creating that alternate (original) timeline, sends Serum Queen and WR Robin over to be themselves.
