Theory Time
So like- I don't make posts very often, if at all, and this will just likely get swept up in a sea of other posts but-- this Lore Olympus update got me thinking... So far Rachel has taken the time to show us that all the key 12 Olympians have been at least named and exist- save Dionysus. Those that know his myths know that he at least has his foundations set but really it's just a little reference... unless it's not.
As of right now, some of the OG mythos references that have come up and been more focused on than others are the infancy of Zeus and Semele's relationship, Persephone's smothered upbringing, Hades' traumatic upbringing, his sterility, and his apparent want to have children (Persephone may have expressed the same in the past but if so I can't recall it right this second).
Now hear me out, all of these could be unconnected and just serve as character defining events and a little wink to a God that isn't around yet, but part of me wants to connect them as foreshadowing and a plot basis when I consider how the Semele myth usually ends... yes the poor girl getting vaporized at the sight of raw Zeus and the wack ass leg birth, but also Dionysus' fostering for his own protection.
In the original mythos Hera wants baby Dionysus dead because he's a bastard son of Zeus, yadda yadda... but LO Hera seems a little less murdery- and this seems like maybe- more of a scandal that Zeus would want to cover up? Well regardless of what the why could be- the outcome from there is typically a toss up depending on the storyteller, Dionysus in some cases is raised by wild animals, in others it's a mortal couple, but in some... He's given to Persephone... Hell, in some cases he's even mixed in with another minor God, Zagreus, who in some of his mythology is characterized as the son of Hades and Persephone.
It's not a super solid foundation but like it has enough narrative support to be a possible outcome- And maybe if Hades and Persephone can't have their own children they could happily adopt once their current issues are squashed...
