Mr. Steward is the executor of the Milton Estate. While he can’t exactly keep the ferrets from doing stupid things with their money, he can at least make sure they don’t drive themselves into poverty, or sell all of their business ventures in order to purchase an iceberg from a shady entrepreneur. Diligent, efficient, and highly professional, his patience with the ferret's high-jinks has limits. In one episode, after Karishad tricks Keene Milton in getting himself locked in a zoo cage, Mr. Steward lets his boss spend a couple overnights there. When he finally gets out, Keene lets his asset manager see his displeasure. However, Keene's trust in Mr. Steward survived and it is clear the ferrets regard him as a friend. He may no longer be worthy of that trust. Recent developments reveal that Mr. Steward and Thomas Milton, villainous brother of the ferrets' benefactor, are plotting against Keene and his foundation to steal their fortune.
