Several questions were left hanging at the end of Season 2: What happened after Angela and Hodgins fled the altar, leaving Brennan and Booth to fill the gap? Will Zack go to Iraq? If so, what will happen to him there? Will Cam and Booth resume their on-again, off-again relationship? In the third season of Bones, Brennan and Booth find themselves on the trail of a serial killer who discards his victims' remains off freeway overpasses. Brennan also must deal with the trial of her father, Max Keenan, for the murder of the Deputy Director of the FBI.
