I don't think you will get an answer to fit your very specific criteria. I can't imagine there is a women in the world who hasn't felt the sting of someone they thought was a friend who wasn't. Erica's stories are inconsistent and Sutton called her on it. She didn't scream at her, snap her teeth or threaten promise she'd regret it. When Erika told the group she didn't want to talk about Tom calling her they dropped it. Not the Garcelle of it all but the T & E of it. She could have done the same about this. But she needed to get this dementia/TBI story out there.
