Rob Campos is an intelligent man but as well extremely gullible.

Ms. Brodie fooled both he and Paige into believing her to be other than her true self. She is an expert at doing that. She induced Rob Campos to believe her an intellectual with emotional depth, savvy and flair, when in reality, she is nothing more than a sack of bones dressed in tasteless chemises and is solely centered on herself. She lacks feminity and endearing qualities. Her facial expressions reveal the cunning sides of her personality.
She fooled Paige into believing her her friend when in reality she confused Paige into making mistakes that would clear the way for she to be chosen by gullible Rob. Who thought she was more mature than Paige and more in tune with him.

As far as next week's visitor, that individual could either be Paige or for reasons I cannot divulge here, Alima Ravenscroft. Both Alima and Paige are total antidotes to Erin Brodie dry and complexed personality, and bond to remind the last three contestants of what real women are all about.

Ms. Brodie was chosen based on her father's immense popularity, this monumental error of judgment has driven many viewers away. Paige or even Kelly would have given FLOM#2 real luster, excitment and human drama to be enjoyed by all watching. They would have given FLOM#2 a good dose of real reality.
