Last time Bones gave us with a promising though anti-climactic wrapping up of the dormant “Gravedigger” story line. This week the group brings the campy corpses back with full force with the murder of a Sci-Fi Convention booth babe.

A group of preteen nerds find a particularly disgusting corpse in the park. After tracing the victim back to a Sci-Fi convention, the crew becomes embroiled in the world of fantasy geeks and medieval weapons enthusiasts. Booth is out of commission this week with a back injury, so agent Prada is paired up with Bones for the investigation.

Prada and Bones are chafing under their new partnership. Throughout the episode there are several references to Prada’s interest in Booth as well as the repressed relationship between Bones and Booth. Though the show continues to dance around it, my guess is we’ll see Bones and Booth’s relationship sprout some before the end of the season.

The first suspect questioned by the new team mates makes and sells replica weaponry. He’s nervous but seems sincere. We learn that the victim may have been trying to sell a very valuable movie prop sword. The Bones’ writer’s really tries to bolster the value of “Excalibur” throughout the episode. Its a bit stilted but they use the value of the sword as a red herring for the crime’s motive. After searching the victim’s ransacked apartment, an answering machine message leads them to a black-lipstick wearing dominatrix who collects medieval weaponry. For one of the first times in memory, Dr. Sweets is key to the entire episode. He cracks the goth woman’s facade, but it seems like a dead end.

After a few other suspects and suppositions, the crew finds the sword buried in the park. The suddenly helpful Dr Sweets suggest that the set the sword up for a fake auction at the Convention. After getting into a heated bidding war with a shadowy Englishman, Sweets and Bones head back to the lab celebrating their false victory. In a proper moment of surprise, a man in a black knight costume smashes Sweet’s car forcing them into a ditch. After the crash, the Knight takes the sword from the wrecked car. As he tries to make his escape, Bones wakes up and leaps into action and fights him hand to hand. Using some hilarious forensic kung fu Bones fights off the knight and takes the sword back as he flees.

Later at the lab, it occurs to Bones that the knight was fighting with authentic medieval style and armor. After finding some authentic chain mail on the spot were they were attacked, the dam breaks and Bones realizes the killer’s identity. It was the meek and sincere replica weapons dealer. He had fallen in love with the victim and his overwrought sense of chivalry drove him to murder.

Bones is not a series you look to for social commentary. Its goofy and childish. Allowing the crew to romp through a Sci-Fi convention was actually a stroke of genius because you can portray cosplay nerds as crazy as you like without any repercussions. The next group Bones should touch on should be the furries.
