TY hopper, that is my assesment as well. I posted this a few days back but nobody seemed to think I was on to something.
The note referencing being in control, IMO shows it was written and concieved of by someone who deeply resented a loss of control or a challenge to control.
Now from ALL appearances and according to most folks impressions here - AB was rather passive and not once has been described as controlling. EB on the other hand, was described as such by the boss, and by many close associates and family members.
This tells me, she alone authored that note, and was NOT put up to it by AB as she implies in her poor me missives to "damien".
I am glad to know I am not the only one who sees it this way.
