My brother rules!
It came down to Isaac and one other kid from the same region and after 15 rounds of a spell off, the other kid missed one and Isaac got the next round's word right! He won on "misanthropic", which I don't think was near as diffucult as some of the other words that were thrown at the two boys.
I'm proud and excited!
Way to go Isaac!
(I'll have pictures of it later).
