>>56445605In the games, Lusamine appears to be a trophy wife because it was revealed that Aether Paradise originally belonged to her father. Mohn was a worker there, and due to his impact there and Lusamine's shitting up the place, it seems her father have transferred responsibility to his
son-in-law.In USM she is more of an antihero than the person who freezes Pokémon and mistreats her children.
In the Sun & Moon anime, they took a different route from the games, portraying Lusamine as a very busy businesswoman who has little time for Lillie and Gladion but cares for them, even Lillie's reaction is like an spoiled child rather than full hating her like the games.
Tomiyasu gave Lillie's family a happy ending in Journeys, unlike the bittersweet ending in USM
As you said, Lusamine is interesting because we get to see many facets of her life and her interactions with her family members.
