The scene where Green Lantern is holding Supergirl after she's been knocked unconscious is a direct homage to the cover of Crisis on Infinite Earths #7, where Superman is holding the corpse of Supergirl. See more
It is incorrectly stated in this episode that the action takes place in the 31st century. Dwayne McDuffie
himself acknowledged this, because in Superman: New Kids in Town
, the year is plainly given as 2979. The characters that appear in "Far From Home" are hardly 21 years older then they were in "New Kids in Town." See more
