She's super sus!! When Albert was about to heal his sister (when I think he was temporarily broke out of heroine's spell) then Liz suddenly became defensive and shouted 'Alicia attacked that weaponless man!' If she was as saintly as she claim to be, can she prioritize Alicia's well being first before doing something outrageous like being defensive. She didn't even try heal her as soon as she saw Alicia got hurt (which was so much unnatural as a saint, if she truly as she claims to be).
Another thing, if she truly embraces equality. She would be concerned with her ONLY FELLOW commoner. She didn't believe Gil/Jill when he shouted that the man is the bad one (It's not even Alicia who shouted it). She didn't even checked his well being as a person on the floor with obvious injuries. ╮( ̄▽ ̄)╭
I therefore conclude she's a fake saint! Lols. Either that or she's a reincarnated person or with previous memories.
Another annoying thing about her as to why does Duke so pissed at her it's because of her conceited attitude. Duke was hurt during the kidnappings, if she's a good girl as she portray to be, she should be worried or even says SORRY to Duke for being hurt because she didn't stop the kidnapper from moving ended up Duke getting hurt ヽ(`Д´)ノ
Instead, she focuses on being on defensive mode out of nowhere when Albert was supposed to heal his sister. I think aside from hurting Alicia, that's the reason why Duke was pissed at her aside from Liz trying to get close to Duke halfheartedly. Liz felt not obligated to apologize to anyone hurt at that scene nor even attempt to heal them (which of these shows she's a saint or even a just good girl?). She's not reflecting on her actions at all since she felt she didn't do anything wrong and was even comforted and supported by her followers but suddenly felt threatened or even just aware of her difference with Alicia when she can't get attention from Duke unlike Alicia does.
Her speech to her expression to the point I could hear an annoying voice dubbing her lines like tell me I'm not imagining things but she could be a great gaslightigher twisted girl
