It’s never been stated FW partipiated (or not) in the revenge convo, correct? Only that it took place in her home with her in attendance (I picture them clustered around the kitchen table).
My point: if, during her GJ appearance she was asked if such a convo took place, she likely denied it. Why? Two reasons. IMO. One, she thought her home secure. Because she limited access to family or well trusted persons. Two, because she assumed her family to be waaaaaay up the **** creek & didn’t want to add to their problems.
I found these story lines interesting. Albeit, lengthy.
