Picking up on the moulding vomment, think about previous winners. Tim, nice guy, quite competent, easy to mould. Michelle, competent(?) easy to mould (in more ways than one it seems). In both series the loud mouthed brash people (Paul, Saira, Simon, Ruth, Sayed etc etc) all got close but never won.
So does that follow for this one? Is Tre one of the loud mouthed ones who will ultimately fall? Who out of the people left is someone who can be moulded?
