Myths, being stories, often contradict.
The two big ones I’m aware of-
1 Persephone was kidnapped and basically Zeus married her to her rapist for all eternity. Hopefully not the one used here.
2 there was no kidnapping, Demeter is just a crazy overprotective mamma bear who can’t accept that her baby girl is old enough to leave the nest.
It doesn’t help that historically the difference between marriage and forced kidnapping hasn’t always been as clear cut as one would like.
