- Bobby owns Singer Salvage Yard (also seen written as Singer Auto Self Service Salvage Yard, on a sign in Everybody Loves a Clown,) and lives in a house on the premises. His exact location is not given.
- Owns a blue Ford tow-truck with Lawrence County, South Dakota plates : 9NO3L1. This is probably a reference to Jim Beaver's role in the HBO Western drama Deadwood. Deadwood is the county seat of Lawrence County.
- Gathering from the wealth of books in his house and his dialogue and role in Devil's Trap, is somewhat of a demonology expert.
- His dog is called Rumsfeld, a reference to the US Secretary of Defense, Donald Rumsfeld.
- John Winchester and Bobby are not necessarily on good terms (Dean comments that the last time Bobby saw John he nearly "filled him with buckshot").
- Bobby gets people to drink holy water to test whether they are possessed. He gives Sam beer laced with it in Born Under a Bad Sign when Sam is possessed and Ellen has to drink a holy water shot in All Hell Breaks Loose: Part Two after she escapes the demon attack on the Roadhouse.
- The name 'Bobby Singer' is a reference to Supernatural's executive producer, Robert Singer.
With John held captive by the demons, the boys turn to Bobby for help. When Meg turns up at his house, they restrain her using a devil's trap (symbol) painted on the ceiling. It is Bobby who alerts the boys to the fact that Meg is not a demon herself, but a woman possessed by one. After the demon is exorcised, and Meg dies, Bobby agrees to dispose of her body and the authorities (he had already placed a 911 call).
With Dean in a coma and John injured, Sam goes to visit Bobby who has towed the Impala from the crash site. Sam has to retrieve the Colt, and John has given Sam a list of herbs to get from Bobby. Sam is distressed at the wrecked state of the Impala, and Bobby suggests scraping the car, until he sees that to Sam it embodies the state Dean is in, and to give up on the Impala would be to give up on Dean. He also informs Sam that the items Sam has requested are not for repelling a demon, but for summoning one.
Although Bobby is not present in this episode, Sam and Dean are staying with him as they recover from their wounds, and the death of their father. Dean uses Bobby's tools to repair the Impala. They have been there a week at the beginning of the episode. Bobby lends them a van (which makes Dean feel like a "soccer mom") when they drive to meet Ellen at the Roadhouse.
When Sam is possessed by the Meg!Demon, he turns up at Bobby's place, intending to kill him. However Bobby is alerted to the demon's presence when it reacts to holy water he has spiked Sam's beer with. Again, the demon is restrained under the devil's trap (symbol), but this time the exorcism Dean attempts fails becuase the demon has bound itself to Sam's body with a brand. The demon is expelled when Bobby burns across the brand with a hot poker.
Bobby is aware Sam killed another hunter, Wandell, while possessed, and advises the boys to leave before other hunter's find them. He gives them each a charm to ward off possession.
When Sam disappears, Dean turns to Bobby for help. Together they search for Sam, and find the burnt out ruins of the Roadhouse. After Dean receives the vision of Sam's location, it is Bobby who deciphers that the town is Cold Oak. When they arrive there, Bobby pursues Jake after he stabs Sam, but loses him in the woods.
Bobby tries to look after Dean in the wake of Sam's death, but Dean pushes him away in anger. Bobby responds with understanding, and leaves. When Dean and Sam turn up at Bobby's, he immediately knows Dena has made some deal to resurrect Sam. Out in the middle of his junkyard he confronts Dean, and is upset when he learns Dean only has a year to live. His affection for Dean is clear, when he despairs that Dean doesn't value his own life.
When Ellen appears, having escaped the demon attack on the Roadhouse, Bobby makes her drink a shot of holy water to ensure she is not possessed.
Bobby is part of the effort to stop the opening of the Devil's Gate in Wyoming, and it is he and Ellen who actually close it.
