I agree about Michael, they need to tone down the Big Brother's favourite and decisions and tasks that make it obvious and just let him function as all the other housemates do and just stir the pot. Hopefully the Head of House things either stop or get passed onto another housemate which will let the suspicion of Michael dissipate for a while.

Although he should be revealed around halfway through. If you leave it until the end, most of the housemates will have been evicted and we won't get to see much of an in-house reaction.

I can see them doing it gradually, such as a housemate passes a task and they get let in on the secret by BB.
