 Like other Observers that have appeared on the show, September is only seen wearing a plain black suit and black fedora, and is pale, bald, and lacks eyebrows.They exhibit several strange mannerisms such as awkward phrasing when talking, a preference for extremely flavored, like spicy or salty foods due to an extremely dulled sense of taste, and the ability to appear or disappear when one looks away.They also use an alien written language with which they maintain copious documentation in small notebooks.
