Bones - Season 5 - Eps 13: The Dentist in the Ditch
When a human skeleton is discovered in the trenches of an old Civil War battleground, Brennan and Booth are called to the case.

While Booth investigates suspects, including the victim’s former boyfriend, Hodgins and lab intern Vincent Nigel-Murray work doggedly to clean the bones of a stubborn clay residue which is preventing the team from determining a cause of death. Meanwhile, Booth’s brother, Jared, returns from his travels with some suprising news.
