Nadia describes herself as 'A very lovable and likeable sort', which to me is big headed. I think she thought Katy H was going to be disliked in the house and she Nadia would be the motherly, peacekeeping one who everyone depended on for food and nurture.
The fact that Katy H was liked by almost everyone except Perez came as a bit of a shock for Nadia I would imagine.
She was then stuck with Perez because he was the only other housemate who disliked Katy H as much as she did and even though she has stirred things and bitched behind Katy H's back, she still hasn't made herself indispensible as she thought she would. Good riddance to the harpy.
