A few groups are far enough along to talk scenarios:
Fruit: dragon dor, with 8 wins, has clinched at least a tie. Hwhr and hiddendragon can each (but not both) tie with 3 week 5 wins.
Chef: I'll conditionally give lok and I the win in the remaining week 4 game. If that happens, lok would have 7, and nate and I 6. But nate has 3 week 5 games and lok and I only have 2. I have to win the South America game to have any chance.
