The S4 finale was written by Marc Maron to serve as a likely series finale, as he was pretty sure that IFC would not renew the series for a 5th season and was given general hints from the network to write the end of Season 4 and finish telling his story as he wanted to. IFC announced that the S4 finale would also be the series finale on July 11, 2016, two days before the episode aired.
