The most talked-about episode of the new season of “Master of None” doesn’t revolve around the show’s main character, played by Aziz Ansari. Instead, it’s episode 8, “Thanksgiving,” in which we watch Denise, played by Lena Waithe, navigate coming out to her mother. It’s a beautifully crafted episode, one that teases out the nuance and complexities of a black queer woman’s relationship with her mom.
