Dean Winchester is named after his grandmother, Deanna Campbell.

God, initially known to Sam and Dean as Chuck Shurley, is a powerful primordial being who created the universe and nearly everything it contains, including the low-selling Supernatural book series, which he writes under the pen name Carver Edlund.

Dean has fought his way out of dark places before, and he'll do it again, the same way he always does: with bullets, bacon, and booze.

In "The One You've Been Waiting For" (Season 12, Episode 5), Dean kills Hitler who's soul has been trapped in a gold pocket watch for 70 years.

In "Pac-Man Fever" (Season 8, episode 20), Charlie signs forms to have her mother taken off of life-support, but before she lets her mother die, she reads The Hobbit to her one last time.

Dean immediately recognizes his favorite episode: "A Night Of Fright Is No Delight".

Season 10 episode 17, "Inside Man", is the ONLY episode in seasons 1-10 that doesn't have an onscreen death.

Rick Grimes is a survivor of the zombie apocalypse in AMC's The Walking Dead.
