Following her departure, creator Andrew Marlowe confirmed that the show was actually ending, despite reports that Nathan had already signed a contract for season nine. He tweeted: "To the whole Castle family- our amazing cast, our remarkable crew, our imaginative writers & our wonderful fans, thank you for 8 amazing years!"

Stana and Nathan reportedly didn't get along on set

In a rare comment about the show's ending, Nathan told New York Post: "It wasn’t the beautiful send-off that I think maybe you could hope for, but it’s the entertainment industry, it’s a business, I get it,” Fillion says. “I don’t take it personally when a show gets canceled — I can’t take it personally, all my shows get canceled! Look at my resume, it’s a long list of canceled TV shows.
