In Plain Sight is the eighth episode of the second season. It was released on 18 November 2005.
Data from a meth lab explosion reveals a photograph that triggers memories for Charlie and puts him at loggerheads with Don, who's focused on tracking down the drug dealer who set off the explosion that killed one of his agents.
The image comes from the concept of hiding in plain sight, one of the primary tenets of prestidigitation, and many forms of con. Its successful execution often requires high levels of chutzpah.
