The cerebral Lance Sweet earned his place among the FBI/Jeffersonian crew, despite skepticism from both Brennan and Booth.

Aubrey enjoys some of Jack's famous recipe flapjacks as they talk about the murder of a lumber jill on Bones.

Dead bodies of people connected to Booth's old Army unit begin to pile up on Bones. "The Scare in the Score" is the seventh episode of the show's 12th season.

It's time to get to work on Bones. The team gathers around a few, well, bones in this shot.

Will Brennan and Crane work together or kill each other?

Booth and Brennan go undercover at the demolition derby on Bones. "The Steel in the Wheels" is the ninth episode of the show's 12th season.

We'd say our favorite undercover duo has returned in the nick of time. After the drama of having someone trying to kill her children and then suffering through her father's murder, Brennan could sure use something to make her smile. <P><P> It appears that getting behind the wheel at the demolition derby may be just what the doctor ordered.

Yes, Wanda's got that awesome curly, frizzy, 1980s big hair look, but there's just something about Buck's mullet that makes us unable to look away...even though we might want to.<P><P> When not even someone as handsome as Booth can salvage a hairstyle, you know it's time to retire it.

So who do you think is going to be driving in the demolition derby? We're sure that Booth will want to take control but Brennan's definitely going to want to drive something other than her Prius. Perhaps they'll both be out there driving on the dirt.
