Weekend at Bobby's

Having given up his soul to the demon Crowley a year ago in a bid to end the Apocalypse, Bobby puts in motion a plan to get his soul back, but encounters a series of distractions over a very long weekend as he provides support for Sam and Dean while they hunt down an ancient greek monster called a lamia, and helps Rufus - who has the FBI on his tail - bury a Japanese okami demon.

When the okami escapes, Bobby tracks it down and destroys it, but not before it ruins his chances of getting to know his next-door neighbour, Marcy (played by Glee's Jennifer Aspen).

Learning Crowley's real name is Fergus Macleod, Bobby then conjured up Crowley's long deceased son to learn the location of his burial ground. Dispatching Dean and Sam to the site in Scotland, Bobby summoned Crowley and threatened to burn his bones unless his soul was returned.

In defeat, Crowley destroyed the contract and fled to collect and hide his remains. With his soul intact, Bobby thanked the brothers for their help - but there's something not quite right with Sam... Why is he so cold?
