My list is
Juliette and Brooke
Gia
Bec
I think Bec has issues, but a sober Bec is capable of reflection. I suspect Gia has insecurities which could possibly be worked-through.
But I think Juliette and Brooke are deeply unpleasant and spoilt women who have used their looks to get what they want in life, and nobody says no to them; they have probably always ruled the roost and think they deserve the world. They don’t care who they have to stomp over to get what they want.
