Description of Joseph John Gribble (John Redcorn's son):
Joseph is the best friend and neighbor of Bobby Hill. Unbeknownst to him (and Dale), John Redcorn is his true, biological father, whom he closely resembles; his conception was the result of the 15-year affair between John Redcorn and Joseph's mother, Nancy Hicks-Gribble. Joseph was conceived while Dale was out investigating the Marfa Lights, leading Dale to conclude in one episode that aliens actually impregnated Nancy.
