The conversation reveals a humorous exchange about a unique cocktail favored by Bertin. When asked about what he was demanding, D'Agosta learns that Bertin enjoys a mix that combines lemon-lime soda, vodka, codeine, and a Jolly Rancher candy, specifically the watermelon flavor. The incredulity in D'Agosta's reaction highlights the absurdity and eccentricity of such a drink.
Despite D'Agosta's surprise, another character points out that this peculiar cocktail actually has its origins in Houston, not Louisiana as D'Agosta assumed. This adds an interesting twist to the setting, as it suggests that cultural quirks and trends can spread, defying geographical boundaries.
