Molly "dumbed-down" her family
So in episode 2 of Epithet Erased, we learned that Molly has a crippling fear of fire, we also learned that her mom died(from that a fire? I still don't know).
Now what-if, it's because of the trauma that incident of losing her mom caused, that Molly had a breakdown, and that breakdown made her unconsciously use her Epithet, resulting in her dad and sister becoming "dumb".
Her dad is neglectful to the point that Molly is the one running their store and even filing their taxes. And her sister(from what she told to Giovanni) uses her Epithet without thought of consequences.
Now it might just be the show being dumb as it is that kind of show and I'm just talking a lot of bull, but what if it's actually not?
