She just asked me for a which is a non-restocking old trivia prize selling for over 4 milllion. Something like that doesn't belong in quest items!

I don't know if will take this one out of her item pool, but I know she took RD items out of it. this may just be a case of "all quests aren't worth doing, you should forfeit it"
She asked me for one of those today as well. I just quit the quest.
I've noticed a number of quest NPCs have started asking for really pricey items as of late (especially Carl and Alexander).
When I saw the title for this, I thought it was about Cinthia's NPC List entry and her being an orphan... so I hoping this was about an sP drive to get that little girl some new toys a big house to keep them in. I am disappointed.
And I am also a little frightened as to why she was so determined to get that item that she asked two people for it on the same day. It is creepy af. (Yeah, maybe some item rarities for her quest need to be checked.)
