Based on his audio log, Jack Fain is a lyricist for the songs in the Bendy cartoons and loves it when everything remains silent. He also seems to admire Sammy's songs, saying that they "always got some bounce". As evident by the fact that he prefers to work in the oddly-placed office in the sewers, he could be considered bizarre, and something of a proverbial outsider, while also introverted, given the constant interruptions in the rest of the Music Department.
