Also, Rebecca's chances of becoming champion of her block are dramatically lowered the moment she shows desire to advance alongside Luffy. Shonen Law dictates she might lose in order to further motivate Luffy with a tragic backstory or something like that.
So the winners could be:
A: Burgess
B: Cavendish/Bartolomeo
C: Luffy
D: Bartolomeo/Cavendish/Rebecca
if I read it correctly..it says "only the ones who survive get a chance"…therefore they might be more than one who survive each group..as for group A Burgess just wipe out everybody so he is the only one survive.
