I just had a thought.

First, the comment that Prince Marcus is actualy Zeus is starting to look more and more plausible, particularly now that a conflict between Zeus and Hades has been canonically introduced into Once. In greek mythos, there was not really a conflict, as the 3 brothers (Zeus, Hades, and Poseidon) divided the 3 realms between them with no one really having an upper hand.

So, what if part of the end of the UW arc is a reconcillation between Hades and Zeus (just like we are likely to see a reconcilliation between Zelena and Regina in "Sisters"). Part of that Reconcilliation is that Hades is allowed to return to Olympus, but that leaves the UW without a leader. Now, taking a page from Pirates of the Carribean, Robin becomes the leader of the UW, and starts to handle the UW in a way that allows people to complete their business and move on rather than being trapped. This is his sacrifice to save his girlfriend and his child. (not to mention a number of friends).

This would break the "curse" of the UW, and the UW clock would start "ticking" normally again. (and maybe they can dispose of that icky red filter).

The grave in the cemetary for Robin is also his portal to be able and visit the world above (and the rest of his friends) in SB. Plus he would have access to the other realms as well, which is why John takes Roland back to the EF where they are more comfortable. (and they will set up a grave there, but that will happen off screen).

Some people may be released back to the land of the living as part of the change of power (which is possibly how Cruella, James, and the Blind Witch can come back). And anyone that comes back will be able to visit the UW at any time (the blood rule holds fast, but since they will all have been to hell and back, they will all possess blood that can summon the boat).

This is very rough, and there are plot holes galore in the story, but it's a start.
