This is like the re-runs of the Paul and Helen arguments. Then it was Paul accused of leading Helen on as a cynical attempt to use her to stay in. This time it is Michelle who get's the flak. If roles were reversed then there would not be a murmer at all.
The wedding task was an obvious set up and Stuart felt uncomfortable, if only he could have articulated what they realised at the end.
There is jealousy around here, but not only from Michelle and not only in the house. Some people just do not like their idols having relationships as they feel they are their's and how day she gett her paws on their property.
