Pandora's Box is the nineteenth episode of the third season. It was released on 30 March 2007.
Charlie splits his genius between finding the cause of a plane crash and dealing with the burglary at his home. The equations for the latter, however, are far less clear, and the costs far harder to calculate - and withstand.
The eponymous jar (or amphora) containing all the ills of the world - and Hope. Metaphorically, a situation best given a wide berth, and one which, if begun, can never be entirely undone or erased.
