If Nikki was/is mentally unstable, she shouldn't have been allowed in the house. If the producers could see mental instability, they still put her in the house and put back in the house after she was fairly voted out. I don't feel as sorry for her as I did for the housemates confined in her company.

Even if Nikki is mentally unstable, I doubt very much if she was unable to control her behaviour. I work in a school in which students all have severe learning difficulties. Behaviour that Nikki regularly exhibited in the house would not be tolerated from the students.
