On the season finale of AMC's "Geeking Out," Robert Kirkman confirmed that the endings of "The Walking Dead" comic series and its hit television adaptation won't be the same.

"I hope [when]the show ends, the comic keeps going," "The Walking Dead" creator told hosts Kevin Smith and Greg Grunberg in a preview of "Geeking Out's" season finale. Restating that he already has an ending in mind for the long-running comic, Kirkman said he's keep that information a secret, "Because I don't want it in the show before I get it in my comic!"

A different ending would only be the last of many departures the TV series has made from the source material. While the general plotlines have remained intact, characters who have already met their demise in the comic live on in the show, and vice versa. Others have been drastically reimagined visually, and one even underwent a gender change in the journey from the page to the screen.

Over the summer Kirkman criticized "Game of Thrones" author George R.R. Martin for allowing the hit HBO drama to spoil plot elements from the fantasy novels on which it's based. He later backed off those comments, saying, "I was just joking about how I would have handled that situation. Love GOT, love GRRM."

The season finale of "Geeking Out" airs tonight at midnight ET/PT on AMC. "The Walking Dead" returns for its seventh season Sunday, Oct. 23, at 9 p.m. ET/PT.
