Why would anyone in the house want or aspire to be like Nikki. In an almost completely open vote where any of the housemates (except Jayne) could have been evicted, Nikki was the one chosen by the public to leave.
So why would anyone want to be like Nikki?
There's no doubt that Ash has changed since going into the secret house, and presumably it's down to the boos that she heard, but becoming more like Nikki... I don't think so
