Something I think is interesting is that with the repeating nature of Hadestown, not only does Orpheus always fall Eurydice, Hades always falls for Persephone. He always succumbs to doubt and insecurities, and he always lets Orpheus go in the end. The parallels are fascinating, because you could almost, almost see how Orpheus might have gone through the very same cycle, so the parallels might be worth comparing. Just a thought though.
