I had the same thought about Morraine and “The Return.” I wondered if the return referred to the kids who went off to fight in the Ogre War and then came home. I wondered if Rumple inadvertedly set Bae up in the same “coward” situation that he found himself in. If all of Bae's friends return from war but resent him because he didn't go to fight, especially since he was willing to go and fight, that could make Bae very angry with Rumple. And it could make him extremely bitter toward his father's curse which allowed him to kill that guards so he could prevent Bae from being taken to fight. If August really is Bae, that situation could his explain his anger over the dagger and his anger over finding his dad in SB.
