Who is Bob Richman from Airframe and what is their importance?

Bob Richman is a young lawyer who is interning at Norton Aircraft. It is rumored that Richman is somehow related to the owner and his family. Richman has worked at the company for several months, but is only this week assigned to Quality Control and to Casey. Casey is annoyed to have the young man following her around, but has done this sort of thing before and finds it somewhat routine. However, Richman's laziness and lack of interest in aircraft technology soon causes her some concern. When Casey is warned by several co-workers that there is something odd about Richman and she catches him going through her desk, Casey begins to suspect Richman is not a simple intern.
