EPISODES
6.04 Weekend at Bobby's
While helping Rufus Turner bury the body of an Okami in his lot, Bobby tells Rufus about Crowley's real name and his affinity for a specific type of scotch, and that he plans to look for more information in Scotland. Rufus reveals that he knows about the scotch, and what part of Scotland it's from, and tells Bobby he has contacts in Scotland and offers to make some calls.
Rufus later reveals what his Scottish contacts found out about Crowley. His real name was Fergus Roderick MacLeod, and he was born in Canisbay, Scotland in 1661. He also reveals that Crowley had a son named Gavin, who left for America after his parents died. He captained a trading ship that went down in Massachusetts in 1723. Rufus also reveals that the wreck was found thirty years ago, and divers recovered Gavin's signet ring, which is now part of the "Treasures of the Deep" exhibit at the Maritime Museum in Andover, Massachusetts. Bobby tells Rufus he needs the ring, and Rufus tells him he's already on his way to Andover. Rufus figures out what he thinks is Bobby's plan: use the ring to summon Gavin's ghost and make an exchange with Crowley: Gavin's ghost for Bobby's soul.
Rufus gets the ring but is being chased by authorities. He swallows the ring so that police can't seize it from him as evidence. Sheriff Jody Mills is able to extradite him from Andover, Massachusetts to Sioux Falls, South Dakota for murder as a favor to Bobby. When he arrives, Rufus gives Bobby Gavin's ring. Bobby summons Gavin's ghost, who asks him if this is Hell. Bobby and Gavin talk for an undetermined length of time, before Bobby summons Crowley.
Crowley repeats his position that he will not be giving Bobby his soul back. At this point Gavin appears, at which Crowley pretends to get emotional at the sight of him, before revealing to Bobby that he and Gavin hated each other, and that Bobby picked the wrong bargaining chip and to go ahead and torture Gavin. Bobby reveals to Crowley that Gavin gladly told him everything about his father. In life, Crowley/Fergus MacLeod was "nothing but a two-bit tailor who sold his soul in exchange for an extra three inches below the belt." Bobby also reveals he knows where Crowley's bones are located.
Using Gavin's information, Sam and Dean travel to Scotland and dig up Crowley's bones, which allows Bobby to bargain with Crowley for the return of his soul.
