Well, i don’t really think they should go into gods. I think it is too problematic. They can have people say they are gods, but they haven’t been so far. Ursala’s dad wasn’t really a god and i am not convinced Hades will be either. It is bad enough they are showing the Underworld and therefore taking even more of the stakes out of death by it just being another realm that they can easily travel to. Especially since it is almost guaranteed that Hook will be just fine at the end of it. Right now the “gods” just seem to be people who live a long time and have some magic, but otherwise are nothing special.
Also, whatever they intended the end of this show to be has been thrown out the window, so who knows what it will be. I don’t think they have a plan besides happily ever after and i only think that because the writers think this show is about hope.
