Fox's long-running crime procedural drama "Bones" is down to its final episodes. After 12 seasons, the show will be coming to a close, and executive producer Hart Hanson reveals the details about the decision behind it.

During the Television Critics Association (TCA) winter press tour, Hanson told the media that it wasn't their decision to end the show but the network's. "We were told it was our last year. It wasn't that we called the network and said, 'We'd like to finish now.' I'm not sure anybody is terribly upset or terribly shocked that it would be the last year."

Hanson is no longer the showrunner for "The Final Chapter" of the series. He shared that he didn't create the ending for "Bones," and that it was all the work of executive producers Jonathan Collier and Michael Peterson. He revealed that he envisioned a different ending for the show; nevertheless, he loves what they have done and that he will still give his full support to what Collier and Peterson created.

At the event, Deschanel told the press that "Bones" has had a great run. She said that they have created several season finales that could have closed the series because they basically didn't know if the network was going to renew the show or cancel it.

Deschanel, however, along with lead co-star David Boreanaz, isn't quite optimistic about a revival. When asked about the possibility of reprising their roles, the lead stars expressed that they need time to consider it.

Although Boreanaz believes that everything is possible, he would rather move forward than take steps backward and do reunions. As for Deschanel, she said that it would be weird if they decided to renew the show when they just said their emotional goodbyes. Like Boreanaz, she isn't ruling out the possibility, but she also isn't ready for a reunion anytime soon.

"Bones: The Final Chapter" premieres Tuesdays at 9 p.m. ET on Fox.
