I don't know about the comparisons with Helen and Paul but I have to say I agree with Sticks to a certain extent.
The female housemates are being judged much more harshly, and forgiven for their flaws much less, than the male HMs. It's not as clear-cut as Sticks makes out - a girl could survive in an eviction vote against a boy but it's less likely to happen.
I would definately like to see Nush stay tonight even though I have to admit she can be annoying - like that laugh she does after she says something and acting like a little girl. But she is genuine and Nush-Scott might progress next week.
