I am not keen on Nadia but I dont think that she has lied to the HMs - she has merley failed to tell them something about herself. I am sure that all of the HMs have something that they have chosen not to share with the others - so what big deal! I think that people are not keeping her in out of sympathy they are keeping her in because they like her. Why would anyone feel sympathy for her she has chosen a path in life and I am sure that she is more than happy with it and would be horrified if she thought that people felt sympathy for her.
She has been very entertaining and is very very witty when she starts, she has risen to all the challenges and look at some of the things she and Marco got up to! so lets be fair here if you dont like her fine but remember it is irrelevant what sex she was born this has been her choice, she is all woman now
