Forgive me if I'm wrong and don't all shout me down, but when the original four became Royals, did not Ant and Dec say they had won immunity from the first vote off. Then,the following night they changed the rules so they had to compete again.
More conspiracy crap! They said that whoever was on the thrones "at the end of Claim of Thrones" would be immune. Why would they being trying to get immunity for someone anyway? If you can't survive the first vote-off, you ain't gonna win!
