Bree took two steps back like she was avoiding a predator, like behind the door was an abominable monster that fell right out of a horror movie. However, in this case was a person who would bring about a situation that was detrimental to her health and state of mind.
Bree couldn't help but wonder why Andrea had chosen to act this way, to be so nefarious, not regarding how anybody felt and just doing what she wanted, even dissembling Bree's own feelings, just to get what she wanted.
She was toxic to Bree.
Andrea opened the door with her spare key and walked inside. Standing in the middle of the room was Bree in just a black bra and loose pants holding a knife at Andrea, there was not a hint of fear in her eyes, contrary to fear, she looked powerful but at first blush, Andrea could tell that her appearance was simply fake. Maybe Bree learnt to use this technique from the masters she trained with, to appear mighty even though she felt otherwise.
