Differences from the Book

  • Simon and Brutus were absent in the episode.
  • Brent does not mention why he does not make himself known to Roxanne; nor does Sammy offer Brent to be friends with Roxanne instead.
  • The episode mentions that humans should have all been captured by aliens like that are like Sammy.
  • In the book, Sammy and his family are aliens who have tentacles and slimy skin. In the television adaptation, they're humans who have faces in the back of their heads.
  • The surprise ending in the episode is mostly different than the one in the book. Even though the twist that Sammy and his family are aliens and that Brent is the last human left on Earth who has to be invisible in order to avoid capture was kept, the book version ends with Brent being taken back to an intergalactic zoo where all the humans are kept. The TV version is a bit more menacing. It implies that Sammy and his family are the aliens who invaded Earth and got rid of all humans (except for Brent).
