Let’s not forget that Zoso insinuated that Bae was not Rumple’s biological son. I think we’re going to see more of Rumple and Milah’s marriage. Perhaps before he went to the ogre wars and just after he returns. I don’t think they will show much of the ogre wars as such because this is a family programme and I imagine the ogre wars to be really gruesome. They’ll probably show snippets revolving around Rumple and his role in the wars and then imply the horror and terror that is involved. Sometimes leaving things up to your audience’s imagination is more effective than actually showing it.
I don’t think Zoso was saying that Bae was not Rumple’s son in the literal sense, but was really just mocking him. Zoso was saying how such a brave boy like Bae could be the son of such a coward.
