[Dash Darington]

Is he permitted to wait until after nominations are announced to decide he wants to be immune? That seems like a crazy amount of power, and almost forces people to nominate him just to burn up his immunities. He should have to decide to use it before the nominations are read.

edit: If I were in his shoes, I'd say I was going to use them for the first three weeks, then not use one the first week. People would assume any vote cast for him would be wasted and he'd get a free week out of it. Then I'd use the rest for weeks 2-4. If you only survive to the end of the show because you have immunity the public may resent it and not vote for you to win.
