I hope they don't reveal it at all, not even after Chris is no longer the power housemate. They should keep it secret for the remainder of the series. I think it makes the show a little more interesting having this unknown force within the group that no one is aware of.

No doubt the producers will reveal that Chris was the power housemate, and that will mess up future housemates who have the power as they will try and act differently.
