Bobby Singer demon

This unnamed demon took possession of hunter Bobby Singer to get close to Sam and Dean.

Background
Shortly after Lucifer broke out of his Cage, this demon possessed Bobby and answered a call from Dean. He arrived at the Regent Inn Motel by driving the Impala and then greeted the boys with a hug. He assured them that he had not been followed, by angels, demons nor Sam's superfan.

To discuss the message Chuck passed on about Michael's missing sword, the demon showed the brothers a book which featured Michael. He called Michael the "toughest son of a bitch they got", describg him as someone he wouldn't want to meet in a "dark alley". He also said Michael was the one who sent Lucifer to Hell.

As the three prepared to study more about Michael's sword and the message they were given, Sam confessed to Bobby about being the cause of The Apocalypse. He apologized, though Bobby responded by saying such an act could not be easily forgiven, and if all was fixed, he wanted Sam to forget his phone number. Sam then left to find books in a nearby church.

While reading, Bobby told Dean that maybe John was right about killing Sam, because of the problem he caused. However, he was disrupted by Dean figuring out the answer to the message as being John's lock-up. When Dean found the card to the lock-up, "Bobby" dropped the ruse and attacked Dean.

Shortly after, Meg and other demons arrived. Bobby's demon held onto Dean while Meg revealed her identity and what she thought about the situation. She then ordered the demon to kill Dean with the Demon-Killing Knife, but he hesitated, and was eventually overcome by Bobby, who took back control and stabbed himself and the demon in the stomach, causing paralysis to himself and killing the demon.

Bobby would later explain to both Sam and Dean that much of what the demon said was false, and had nothing to do with what Bobby himself felt.
