Charlie has done this many times before. He encourages them to break the rules, but says he had nothing to do with it.
It was the same when most of the housemates [except Lisa & Rodrigo] where going to openly discuss nominations with each other and jokingly tell each who was going to nominate who. But Charlie was egging then on and being part of the group, but not really getting involved. Then he went in and nominated them. But the others were not fooled and nominated him cos he being fake. It was just a pity that all the newbies went up that week.
Charlie pretends to be invovled in things like that, but stands at a distance so that he doesn't do himself damage. He's even nominated his buddy Rodrigo because of an arguement. Rodrigo has never done that to him. Some friend Charlie is. He is just using Rodrigo for attention. He is a manipulator!
Get Charlie out!
