Okay...I think this week's big point earner is gonna be: Goes in the water.
Now we know Ian is a definite. And I think Tom, too. But if Ulong wins the reward, then some others will be fishing with the new gear. I personally think Koror will win because they'll get the flint back and will be able to cook a feast. Since Ian is the dolphin trainer, he's the obvious one to do the fishing, too.
Therefore, everyone better have Ian on their team.
Good luck everyone!
