|Episode(s)||4.20 The Rapture|
A devout Christian before his possession, he is married to Amelia, and has a daughter named Claire. Prior to giving Castiel permission to inhabit his body, he sold "ad time for AM radio". The suitability of Jimmy being able to host an angel is said to be in his blood. He is able to process and understand the angel's real voice, and he hears the angel speak on multiple occasions before his possession. On one occasion, Castiel asks him to prove his faith by plunging his arm into boiling water. Jimmy is unharmed, and reveals his interactions with Castiel to his wife. She does not believe that he has been contacted by an angel and begs him to get psychiatric help. She gives him an ultimatum: either he receives treatment, or she will take their daughter and leave.
The Vessel of Castiel
Faced with this situation, Jimmy dresses in a suit and trenchcoat and stands in front of his house. He prays, and Castiel answers. Jimmy agrees to act as a vessel, provided that his family is protected. Castiel descends, possessing him. Jimmy becomes a vessel not long before Dean is resurrected. Almost a year later, he is released when Castiel is recalled to Heaven for "re-indoctrination" after concern from his superiors that he is becoming disobedient and too close to Dean.4.20 The Rapture Sam and Dean find Jimmy in a ruined warehouse after Castiel's forced removal. In conversation, Jimmy reveals that his experience as a vessel was unpleasant, and that he is anxious to go back to his old life. The brothers attempt to prevent Jimmy from returning to his family, on the grounds that demons would be interested in him as a former vessel, but Jimmy escapes their custody. He returns home and tells his wife that he has been in a psychiatric hospital, and his family is all that matters to him.
Demons eventually track Jimmy down at the house, but he and his family are saved by Sam and Dean. Jimmy agrees to be separated from his family, but it is too late: his wife was possessed during the struggle at the house. She orders Jimmy to surrender himself at a warehouse. Before entering, Jimmy yells at the sky, directing his tirade at Castiel. He accuses the angel of breaking the promise to protect his family, and of taking everything Jimmy offered (and more) without any form of repayment. Jimmy, Sam and Dean are captured, and Jimmy is shot by his possessed wife. They are saved by Castiel, who has taken Jimmy's daughter Claire as a vessel. Jimmy, near death, begs to be allowed to act as a vessel again to spare his daughter. Castiel agrees, and re-enters Jimmy.
Castiel and Jimmy Destroyed
Jimmy's body is destroyed by Raphael when he kills Castiel at the end of 4.22 Lucifer Rising following Castiel's rebellion against Heaven. What happened to Jimmy was unknown at the time. However, when God resurrects Castiel from the dead in 5.01 Sympathy For The Devil, he returns in Jimmy's body, where at least part of Jimmy's essence is still alive and present in the vessel, as Jimmy's taste for red meat affects Castiel during the events of 5.14 My Bloody Valentine. Castiel devours hundreds of burgers when Famine amplifies Jimmy's craving. Castiel and Jimmy were destroyed a second time in 5.22 Swan Song, when Lucifer causes them to explode in retaliation for Castiel's assault on Michael. God resurrects Castiel from the dead a second time, and he again appears in Jimmy's form. Jimmy's presence in the body has not been established following this second return. However, in the episode 5.21 Two Minutes To Midnight Castiel tells Dean over the phone that the doctors believed he was brain dead, so it is possible that he died and Castiel is merely possessing his body, though this conclusion is as yet unverified.
- The name Jimmy Novak may be referencing Jimmy Stewart and Kim Novak who starred together in the Hitchcock movie Vertigo, which is about a woman who is not whom she appears to be. There is also a real Jimmy Novak who is a Chicago radio host who used to run a segment called "4:20 Hit of the Day".
