Louie...doesn't talk much he hasn't spoken to anyone in years. His brothers are one of the contributions to that his brothers were always having arguments and asking for his opinion if he sided with one of them the other one would beat him up so he just stopped talking and having opinions altogether.
After an argument between Louie and Scrooge he realized he's nothing like him so when someone offers him more then he could hope for will he be willing to risk his own life for it? Or even his families lives?
Story 1:
Babies always get the advantage, they get everything they want, in Louie's case, this is true most of the time, but he begins to get annoyed by all the babying that his older brothers give him.
