Don't forget that Billie still has her high school bully mentality. I can see people giving Carla a pass since she's rich and no one wants to risk it turning into a civil rights thing and I can see people being upset with Mary trying to get some personal benefit out of Ruth's breakdown, but realistically all it would warrant is a "what a bitch" response to Mary and no one giving a shit about Billie, especially after being revealed that she was nailing Ruth. >>103750383
Hey now, she did threaten Ruth to allow her to hold a public prayer in the meeting room.
In all honesty Mary reads far closer to mild parody of fundie types than an actual antagonist.
