So you, her, and lunala go to the UB world and find her Mom, who screams that she doesn't NEED Lillie she doesn't CARE that she's her daughter she doesn't listen and she has "become ugly and useless"
No, we win and the jellyfish leaves and I thought maybe she was dead but no she seems like she might be learning because it's Pokémon everyone has happy endings
But long story short I love Lillie and I kind of see myself in her to an extent and naturally Angela just saw her as "kind of annoying, but a little better by the end"
