Check Your Head

S4, E17: The team members search for Rachel, an agoraphobic advice columnist who had not left her apartment in 2 years.While casing her apartment for clues, they ponder the relevance of a walkie-talkie, a box of bullets and a stack of letters from an array of prisoners and oddballs who were seeking her advice and/or threatening her. As the investigators theorize that she may have fallen prey to an obsessed fan or a recently released convict who had been calling her, they also consider the fact that, as a result of her condition, there was an endless stream of delivery and service people coming to her apartment.
