The whole thing is academic anyway. Under normal rules he was going to be up for eviction each time in the future anyway, so it has changed absolutely nothing in reality. However the fact that the housemates who strongly dislike Perez cannot take an active vote in naming him will probably grate them big time in itself.
Anyway, there are only 2 evictions left aren't there? Friday, and next Wednesday presumably.
He looks set for the final to me now.
