Affectionate Nickname: Not only does Adrien still call Louis "Little Bun" into his twenties, but has also taken to calling Emma "Cupcake" and Hugo "Cinnamon Roll".
Cool Aunt: Apparently Chloe has tried to play this part to Louis, but he had never gotten to calling her "Aunt Chloe" because it doesn't feel natural.
Straight Man and Wise Guy: While they're technically uncle and nephew, Louis and Sebastian are more like brothers, Sebastian inheriting Gabriel and Nathalie's stiff and stoic personalities while Louis likes to poke and prod at him to get a reaction.
