I read that Tim Gunn said Angela kept adding fuel to the fire - footage that we never saw. So I can see why Jeffrey thought he was being set up by Angela and her mother. So I see his actions, although tackless, were not done in the purely mean spirit so many believe. He truly seemed to believe they were working to get him thrown off the show, so he behaved too defensively in the whole matter. Although, I don't believe her mother would plot with Angelica to try and get someone kicked off the show, even if her daughter couldn't stand him. But on some level, whether consciously or unconsciously, Angela was using her mother to get at Jeffrey. Seeing that her mother is something of a drama queen, it worked quite well.
