Bones - Episode 4.05 - The Finger in the Nest

Booth brings to the Smithsonian a finger that Parker found in a bird's nest. The team, along with "grad of the week" 40-year-old Scott Starret, study it to find answers. Scott is Brennan's oldest grad student, the father of four boys, and had many jobs before this, including parks supervisor and car salesman. Booth enlists Sweets help to make sure that Parker isn't stressed for life after having found the finger. Turns out Parker is traumatized but not from the finger. Hodgins opens up to Scott and tells him about his latest problems: best friend (Zach) in jail, his relationship with Angela going south, etc. Cam also appears.
