Seeing BTS pictures of Henry on a motorcycle ... oh, wait, August rode a motorcycle. “August”, the month Henry was born ... August Wayne Booth, a reference to the unreliable narrator ... August, who broke the fourth wall at the end of 4.15 ... Oh.
A fictionalized version of an author who appears as a character in the events of the story is often called upon to comment upon the situation, deliver the author's verdict, and possibly break the Fourth Wall in a self-deprecating fashion. The author character will usually not influence the plot and may be only loosely tied to the goings-on, their appearances being quite random. The highfalutin literary term for a character designed to express the author's preferred opinions is the raisonneur—here at TV Tropes, the preferred term is Author Avatar.
