Well, at least we know the rivers:

The archway over the Blue river says Styx, and Grey river says Cocytus. The lava-like one is likely Phth.........one. The river of Lost souls turns you into a mindless husk, so that must be Lethe (green).

Also sounds like the Dark Curse....I wonder.\

Anyhow, Hook's misery is my joy! Hades seems a bit of an oddball to me, so I can't say yet, if I'd enjoy him, but it does look like a lot of Hades this episode.
