Now this is just pure speculation, but it has to be said. As an editor of a tv show, MB knows that there are not many 8 vs 5 immunity challenges that can be fair for the tribe with only five members. Now the real question comes out: Would Mark Burnett try to make up an immunity challenge that Maraamu can beat Rotu in?? Is there one??
Mark Burnett need to get some character development for the Rotu tribe, but really can't since his other tribe is full of other characters who can't seem to get it together.
We know about all of the alliances that seem to be forming in Maraamu, but Rotu is still a question. Who is in an alliance with who??
I don't see how Mark might not try to give Marlboro a little boost, if not just for a little more of a fairer competition, but for the sake of character development.
