Bea WAS out of order picking on David and stirring up an anti-campaign based on her porkie pies. She was the bully and shouting not David. She has picked up on Marcus's gameplan who has been trying his best to influence HMs views of the HMs he doesn't like himself. Marcus has been working hard on his anti-David campaign since he was put out with David judging the talent contest.
Also, I am intensely disliking Lisa who hasn't the balls to do her own dirty work. She is nasty feeding David venom and using him to fire the bullets for her.
She is worse than Bea because she is so underhand.
GET LISA OUT.
