I think that all depends on which version of mythology you go with. In some Mythos, all the dead travel to the Underworld, In some, there is a place where the valiant go (such as Valhalla in the Norse Mythos) and another that those that are deemed unworthy go. In some Mythos, there is even a third part of the underwold that is reserved for those individuals that have unfinished business, and are not allowed to leave until they complete whatever business is holding them back.

The point of all of this is that First, we don't even know if we are getting an underworld arc (though the general concensus is that we are, but we aren't the writers). And even assuming that we do get the underworld arc, we have no idea which mythos we'll get, or how they will set it up.

My primary assumption is that Cora will be flashback only (as she was in Mother). However, on the off chance that she appears present day only in the Underworld, I look forward to her meeting Zelena. That will be an interesting exchange, to be sure.
