This week FOX will talk with Bones TV series producers, to decide whether or not to renew the crime dramedy for a 12th season. During the FOX TCA party, showrunners Jonathan Collier and Michael Peterson told TVInsider, they are having a great time and want to make season 12 of Bones.

While Bones stars Emily Deschanel and David Boreanaz have filed a lawsuit over profits, which could be moved to arbitration, Collier reports they have both enjoyed this season. He and Peterson also talked about the planned two-part Bones season 11 finale, which could possibly be the Bones TV series finale.

From TVInsider:

As the writers shape the second half the season with its future up in the air, for now, “we’ve adjusted slightly,” Peterson said. “We looked at the last episodes and how we’re going to do it. Right now, we’re looking at a two-parter to finish out the season, with the new serial killer and some special guest cast at the end.”

“What we’re looking for the end of the season is big,” Peterson continued. “It should excite our fans who have been with us from the very beginning. We don’t want it to be the last [year], but if it is, we’re going out big.”

But the showrunners were coy when discussing which character(s) might return for the end of the season. “We might be able to wrap up storylines, we might be able to close certain holes that have been left open in the show over the years,” Collier teased.

One of the bigger holes in Bones is the fact that fans have known since Season 4—but no one who is (alive) on the team is aware—that original team member Zack Addy (Eric Millegan) only helped serial killer, Gormogon, find his victim; Zack never killed anyone himself, but he was willing to let people think he did so he could remain in an asylum versus being sent to prison on a conspirator charge.

But the showrunners wouldn’t confirm one way or another if Zack would return in Season 11. “We wouldn’t rule anything out,” Collier said. (Millegan, who was a series regular for Bones’ first three seasons, last popped up in the show’s 100th episode.)

Last week, FOX Co-Chair and CEO, Dana Walden, was uncertain if Bones would be cancelled after 11 seasons or renewed for a 12th. She did say FOX would only do another season of Bones with both Deschanel and Boreanaz.

Peterson is on record as saying he would like Bones to continue forever.

At the outset of Bones 11th season, reportedly, Boreanaz was looking forward to ending the series.

What do you think? Which plot points and storylines do you want addressed, before the Bones TV show ends?  Is it the right time for the show to go out on a high note?
