If they are playing with O and E myth, then it’s worth pointing out that in the end Orpheus loses Eurydice
In reverse in that Orpheus is Belle and Rumple is Eurydice?
That fits, but I was thinking of it more as an attitude-reversal: instead of journeying into the underworld to try to get her back and failing, he’s come back temporarily to say goodbye so that she can move on from him.
