Some of the humorous lines in “Futurama” appear to go nowhere, such as Leela saying that she “just sold a castle to the King of Space” all the way back in Season 8.
However, these jokes often have follow-up explanations. It’s been over a decade since Leela uttered the line, and now fans finally get to see the King of Space in Season 11.
The show seems to know fans are no longer interested in seeing these love-triangle plots, so they made it a self-contained tale in a four-story anthology episode.
