Charlie WILL nominate him...infact, he practically said so, quotes from convo with Lisa and Karly about nomms; "Well I've got one for definate now" (I think BB may have a word with him for discussing nomms here)
On the other hand, I don't think many of the other housemates have grounds to nominate him; Kris might just because he's close to Charlie and Charlie may have changed his objective, mutual view of Rodrigo but otherwise I think Marcus may be up this week as he has been the revolting old pervert of the house for too long now and is rubbing everyone the wrong way...
Rodrigo SHOULD stay!
