Unlike Huey and Dewey focused seasons, Louie focused season didn’t involve the McDuck family saving the world. It involves from Flintheart Glomgold to Penumbra saving the world from destruction by Lunaris. The “Louie Season” hardly has major Webby story other than bringing Lena back and meeting Violet Saberwing. Huey and Dewey’s respective seasons involves the entire family saving Duckburg and the world while Webby has major storylines like trying to get the family together, Lena, and her origins.
Maybe Season 2 could’ve done more involving Louie like somebody taking advantage of his scheming nature by manipulating him to join forces with Scrooge’s enemies (but betrayal was never his character) to see if they can accept him. That season made me believe that this could’ve involved Louie becoming an outcast of the family because of his nature involving the fortune over his family with most of the schemes (that seem evil) put his family’s lives in danger which is why Della had the right to ground him. Louie should’ve just find it within himself to express himself about his lazy scheming attitude was a mask to avoid all of this mess. If he really wanted to make up for his actions in Season 2 like during the finale, it would have to be pretty epic if he can do something epic.
