While it’s true that series creator Hart Hanson is developing an offshoot that would revolve around the central character in Walter Sherman’s Locator novels, the new guy — a recluse who can basically find anything — will not be introduced in a December episode of Bones, sources confirm. My guess is we’ll meet him in January or February.

HartHanson: Some of the stuff about a Bones "spin off" is accurate and some of it is not. And it's not a spin off.
