I'm going to disagree with the above commenter who claims it's "invasive" to say Brittany was "off". It's not speculation; it's a demonstrable fact. It was Brittany who sent that undead shaman wizard emails about a 16th century dead guy trying to "eat" a real woman's children, revealing both their names and their address. She was "off" in the same sense that Abbey was, ie, she was the victim of a sociopathic manipulator who systematically destroyed her grip on reality. As a result, she made some terrible choices.

To discuss these facts or her relationship with Andrew Blake (the one who posted that video, by the way) is not to impune or disrespect her. Andy used Brittany while she was alive and he continues to use her memory after death, essentially rewriting history to whatever suits his purposes at the moment. You're playing right into his hands if any "speculation" about Andy's use and abuse of Brittany suddenly constitutes disrespecting the dead.
