I think that the whole 'illness' in the camp that has been effecting the squad for the last 3 weeks is a cover-up, for the fact that the squad is in disarray with various factions falling out and fighting and Oscar being unable to control them.
I can't see why others haven't realised. It's so...
But put 30,000 people together for 2 hrs talking bollocks and I should think the likelihood of 5 or 6 talking the same bollocks is fairly high
*edit* But i've put it more succinctly Edna
