"This is someone who is an extremely odd and fearless foe," executive producer Stephan Nathan

tells us, comparing the character to such past serial killers as Gormogon and The Gravedigger. "Only he's going to be much more of a 21st-century, tech-savvy foe."Fox announced last week that Bones won't premiere until Nov. 3, which will allow the network to air six episodes in the fall before star Emily Deschanel takes her maternity leave. Nathan says those six episodes will primarily focus on expectant parents Booth (David Boreanaz) and Brennan (Deschanel) preparing to raise their child together, but they will also introduce the new killer, who will take a while to subdue.

"At the end of [Episode] 6, we want to leave with a real surprise for the audience from a plot point of view," Nathan says. "I'm not necessarily talking about Booth and Brennan... [but this] nefarious character, who we will follow for a little bit this season and perhaps next."What do you think of Bones adding a new nemesis? And what should the writers call this guy?
