With regards to who wins, I still seem to be somewhat neutral.
I seem to have been put on retainer as a cyber "Devil's Advocate" for Jade

(Someone has to do it

)
However it would be beneficial to keep Jade in as long as possible, as it should develop her character in much the same way that Helen's character metamorphosed ddue to her stay on BB2
With respect to Jade's voice grating on people, if someone criticised a person because they had an accent from Africa or Aisia or a Celtic voice, they would be accused of racism. Yet people criticise Jade for her South East London voice with impunity.
Incidently, I was having lunch at the Fox and Hounds in Tadley today, and I overheard someone with a similar accent to Jade
This shows that Jade is not alone in having such a voice, and this makes up the rich tapestry that is the United Kingdom of Great Britain and Northern Ireland
