In episode 23, Flourish and Elizabeth take on the fourth wall—not the metaphorical wall between the audience and the actors on a stage, but the one erected BY fans to separate them (and their fanworks) from creators. After a crash course on the history of the fannish fourth wall, they discuss famous fan/creator clashes, from the Phelps twins confronted with Weasleycest to Benedict Cumberbatch writing het fanfic about Sherlock. And they consider whether any creator can cross the fourth wall successfully—and whether, in the age of social media, there's any way the fourth wall *won't* get broken.
