"The Dentist in the Ditch" is episode thirteen of season five of Bones, the forensic drama television series loosely based on the novels and life of anthropologist Kathy Reichs. In this episode, a rather more recent body is found on a Civil War battlefield.
The Battle of Farmville (Re-enacted)
This episode opens at a re-enactment of the American Civil War Battle of Farmville. A Union soldier and a Confederate are arguing about the battle when they discover something poking out of the ground. Further examination reveals there to be a skeleton in the ground. At which point they start arguing over whether it's a Union skeleton or a Confederate one.
Many, Many Spiders
The body is quite firmly encased in clay, so the entire chunk of clay is cut out of the ground and carted back to the Jeffersonian. Whilst the slab is being examined, many, many small spiders start pouring out of it. Cam, as it turns out, really doesn't like spiders. According to Hodgins, the spiders are not native to the area where the body was discovered either.
The Dead Dentist and the Ex
Removing the body from the clay is going to be tricky, but the skull is accessible, and there are signs of reconstructive surgery that didn't start being done until the Sixties. So, not a Civil War body after all. It belongs to a dentist who hadn't been seen for some weeks, but this was apparently not unusual. There is an ex-boyfriend who is not happy with the dead dentist, as he put him through college only to be dumped afterwards - and with gay marriage not being recognised in Virginia, had no legal recourse.
Removing the Body from the Clay
Mr Nigel-Murray comes up with a way of removing the clay from the body - using rhubarb - and he's also hoping for a bit of positive reinforcement from Brennan. Cam suggests he sets his expectation for such pretty low. Cause of death proves harder to pin down. As does motive. The dead gay dentist also played American football, which is also looked into.
Booth's brother Jared is back from India, and he has fallen in love. Booth thinks that there's something wrong with the woman, Padme, who is actually from Virginia, and teaches grade school. So Booth runs a background check on her. This, not unsurprisingly, does not sit well with Jared.
