I don't think there could possibly be 12 Jades. The world couldn't cope without sliding into world war 3,4 and 5
I think next year if there is one after this year of the gimmicks to save BB scenario, that they will select more robust people.
I hope they don't ever select another Jon. Too many housemates were sacrificed Especially Anouska to keep him in. Now they have compounded the mistake by putting him back.
