Let us ponder what this title could possibly be referring to. Could it be literal-- the legendary Physical Challenge to which bad employee Roth is at last subjected? Could it be not-quite-so-literal-but-still-literal-- the backbreaking labor involved in draining the mysterious flooding of Equinox Manor? Or perhaps it is misspelled-- perhaps we now face the psychic-al challenge of confronting the enemy who hates us more than any other being in the Empire... Well, no, you're right, I think it's probably the first one.
Between the physical challenge and the appearance of the Final Devil, there's an awful lot of awe for us to digest behind the scenes. You could say that this particular tabletalk is truly awe-full.
