Is Biggie targeting Rodrigo?
 

Every time there is a spat between the two, BB calls Rodrigo in before Charlie, even though Charlie is the instigator. They seem to be baiting him while intoning that Big Brother has the housemates' welfare at heart.

If they call Charlie in first he'll just sit there crying that he hasn't done anything, like a kid with jam round his mouth saying he hasn't touched any jam.

Rodrigo on the other hand is better viewing, guaranteed to bounce off the walls in a technicolour hissy fit if they pull him in first. He seems to be teetering on the edge of physical violence now. He's raised the bar from getting in Charlie's face to pulling off his mattress to throwing water about. Next stop - bitch slap?

Rodrigo has a much shorter fuse. I can understand why they called him in first.

BB calls Rod for his own good, they can see he is getting very close to reallt losing it and so the call him in thus stopping him from doing something he is gonna regret.

Rodrigo might easily get violent when he is losin control. It was really close when he threatened and poked Charlie.
