"Objects in Space" is the 14th episode and series finale of the science fiction television series Firefly. Serenity encounters Jubal Early, a ruthless professional bounty hunter who will stop at nothing to retrieve River. But River, feeling unwelcome on the ship, takes a novel approach to escaping from the long arm of the Alliance. River's and Early's tactile and spiritual connection with physical objects reflects an existential experience in Whedon's youth and his subsequent study of Jean-Paul Sartre's existential novel Nausea.
