I don't know so much about this silly game but I think Michelle will be disappointed in herself when she reflects on the opportunity she wasted in the house. She had a platform, search me how she would have used it, but it was her platform. And she has, instead, acted as the Head Girl's sidekick.
Michelle wanted to be an adult - and maybe will realise that that was never going to be possible as deputy head girl to Katie.
She needed to take the lead, never did, and now has to live with the fruits of letting Katie voice all the leading opinions.
