Why is Paige Sinclair depicted as a pig, of all animals? Well, pigs have incredibly sensitive snouts that allow them to sniff out truffles (a rare culinary delicacy) that humans would miss and throughout European and Euro-American history, trained "truffle hogs" have been used to sniff and root out truffles in temperate forests, some as deep as three feet underground! Likewise, Paige can "sniff out" a story in a seemingly innocuous case that most people would dismiss as cut-and-dry. She also has a sophisticated personality to go with the whole "truffle hog" metaphor. (They probably felt that making her a scent hound would be a little tooon-the-nose.)
In season 6, the two reporters investigating Sarah Lynn's death are dressed in attire similar to that seen in the 1930's-1940's. While on the surface it could be seen as a throwback to early cinematic comedies, the duos appearances become more symbolic when you realize that The Chain of Harm for BoJack and the previous two generations in his family started in the 1940's thanks to the death of Crackerjack (who decided to go to war while embracing The All-American Boy archetype idealized back then; a personality trait that made him walk into danger ignorantly and to his death) as well as a grieving Honey Sugarman being lobotomized by her uncaring husband (who was just acting as a "modern American man" and later felt using a lobotomy on Beatrice would be justified if she ever showed too much emotion again, creating her future callous personality). Now, after seven decades it looks as if things are coming full circle for Bojack and for all the drama and suffering he and his family both caused and experienced.
