I have an idea - friendly betting on the winners of the duels. We could bet on each duel and on the overall tournament winners. Instead of money, I suggest we gamble with our time. For example, babysitting hours. A person who lost a bet, could babysit for someone who placed a winning bet. Doesn't have to be babysitting, it can be any useful/fun service - helping Bucky or Lacey with cooking/baking, helping in the medbay, teaching a skill, tutoring a student, helping at Bryn's club, etc.
