Thinking about the parallels and differences between Marie Levesque's relationship with Pluto and Maria di Angelo's relationship with Hades
In both flashbacks, we see Hades/Pluto trying to convince them to stay/go somewhere for their and their children's protection and both women refuse his request, but where those scenes differ is in how they respond to him
Maria is so patient and loving towards Hades. She never raises her voice, she repeatedly calls him my love, and yet is firm about not raising their children in the underworld. She only sees the good in Hades - calls him kind, generous, insists the other gods wouldn't be afraid of him if they saw him the way she does. She has unwavering faith that he will protect her, and won't allow any harm to come to Nico and Bianca. There is actual love there, and we get the sense that they did have a good relationship despite him being a god
Queen Marie, on the other hand, deeply resents Pluto. She's angry to the point of throwing and breaking things around her home, and blames him for all of their misfortune. It's Pluto's fault that Hazel is cursed, it's Pluto's fault that people around them are dying, it's Pluto's fault that the police thinks she's a murderer and her clients think she's a witch. Unlike Maria, Queen Marie doesn't believe that Pluto has ever protected them, nor does she want him to, not after how much he has ruined her and Hazel's life. There's little love there like with Maria and Hades, little trust - just bitter angry resentment.
And it makes sense that they would react so differently! We don't get the sense that Hades's godhood has affected Nico or Bianca in any tangible way (at this point, anyway). They're playing together when Hades visits Maria and seem happy. They're not cursed the way Hazel is. They don't have dangerous and harmful powers that they can't control (that we know of). Of course Queen Marie would resent Pluto in ways that Maria doesn't; the wish Pluto granted Queen Marie has actively made their life worse. The di Angelos were fine. The di Angelos were thriving. They had nothing to worry about until the Great Prophecy was issued, and Maria had no reason to believe that Hades couldn't protect them from Zeus when he had protected them thus far. He hadn't done anything to hurt her the way that Queen Marie believed Pluto hurt them.
But here's the thing though: Queen Marie was being manipulated by Gaia. Both she and Pluto tell Hazel that The Voice turned her against him. Just before Queen Marie and Pluto speak to each other in the first flashback, we see her push back against Gaia's request to go to Alaska precisely because Pluto told her it wasn't safe and that he wouldn't be able to protect her and Hazel there. Gaia was the one who convinced her that it was Pluto's fault that Hazel was cursed; after all, it's much easier to blame him than to admit to herself that it was her wish and her greed for "all the riches in the world" that lead to Hazel's predicament.
Gaia preyed on Queen Marie's frustration with herself and with Pluto to manipulate her into bringing Hazel to Alaska to raise her son from the earth. It was this manipulation that lead her to blowing up at Pluto when he tries to convince her to stay in New Orleans. Maria didn't hate Hades because the gods didn't torment her the way Gaia tormented Queen Marie.
Which raises the question: if Gaia hadn't messed with her head, would Queen Marie have loved and trusted Pluto the way Maria loved and trusted Hades? Could Pluto and the Levesques have played happy families the way the di Angelos did with Hades? It's more complicated because Gaia's absence would not have fixed Hazel's curse so it's entirely possible she still would have resented him, but I have to wonder:
Was there ever a world where the Levesques could have been happy?
[ID: Tags by @/hazellvsq: #what's so interesting is that Hades is generous to them but it backfires so bad #he set both of them up to fail. Marie's wish backfired and maria moving into the underworld was also clearly unsustainable #being like "I don't care what Persephone thinks!" before putting his mortal girlfriend children directly in her turf? he's DUMB #what's also interesting is that Maria is clearly wealthy and living the life Marie aspired towards #which like you said is why Maria feels safe and Marie does not so they have different answers to his offers #also her saying that he warned her meant that they were still in touch which is so chewy to me #anyway amazing post #marie levesque #maria di angelo #nico #hazel #bianca #underworld siblings /end ID]
