On this week's episode of Supernatural…

Frank's hard drive, which contains documents on Dick Roman and information on Sam and Dean, is being hacked by Charlie, a computer whiz hired by Dick Roman.

Sam and Dean come to Charlie with a plan to eliminate the hard drive and access Dick's email in order to discover what he is up to.

The trio manage to learn that an important package was arriving for Dick and the team switches it out with a Borax bomb. Sam and Dean now are in possession of a clay slab.

Bobby is slowly being wracked with a vengeful spirit which ends up hurting Charlie in the process.

Sam and Dean want to know what the clay tablet is and how to handle Bobby's ghostly ways.
