Early Life

Claire Novak is a hunter and the daughter of Jimmy, Castiel's true vessel. After her father's departure, Claire's mother went off to find herself and left her in the care of her grandmother. Her grandmother died and Claire struggled in group homes as well as developing a rebellious nature and resentment to the angel who ruined her life. She fell in with a bad crowd before she encountered Castiel again and refused his kindness, even stealing from him and his allies. Claire soon forgave Castiel after he helped her find her lost mother Amelia Novak but she was orphaned when her mother was killed by a Grigori. Claire personally avenged her mother and decided to be a hunter before she was sent to live with the Mills Family. Though Claire struggled to adjust with them as well as hunting, she came to see them as her family and eventually, she became a hunter.

Claire Novak is the daughter of Jimmy Novak, Castiel's vessel. Jimmy offers himself over to Castiel after his wife Amelia threatens to take Claire to her mother's if he does not get help. After Jimmy says "yes" to Castiel, Claire comes outside and says "Daddy?" Castiel replies "I am not your father" to her and leaves.

After almost a year of Amelia looking for Jimmy and thinking he was dead, he returns home. Amelia lets Jimmy talk to Claire and have dinner with them.

During their meal, their neighbor, Rodger stops over. He reveals himself as a demon to Jimmy, but Claire's mother, Amelia does not believe Jimmy. Jimmy puts Claire and Amelia in the pantry to keep them safe, but Amelia holds Jimmy back, so Claire can escape. Claire does, and when Jimmy and Amelia come out they see that Rodger is holding a knife to her throat. He makes the remark "I told you I'd gut the bitch." Claire calls out for her father as another demon attacks him.

Dean comes up behind Rodger and kills the demon with Ruby's Knife. This frees Claire and allows her to escape with her father. Claire, Jimmy, Amelia, Sam, and Dean meet up outside the house and drive away in the Impala.

Once they stop, Jimmy tells Amelia to take Claire to "Carl and Sally's" house. Amelia agrees and Dean, Sam, and Jimmy drive off. When they do, Claire asks "Why is he leaving again?" Amelia slaps her and flashes black, demon eyes. She says "Cause it's just not my day, is it? You little bitch."

Jimmy, as instructed, comes to the warehouse where the demon possessing Amelia has Claire tied to a chair. Two demons bring Sam and Dean did. Amelia then shoots Jimmy and instructs one of the demons to "waste little, orphan Annie".

However, as the demon swings a pole at her, Claire suddenly wakes up, grabs it and smites the demon before burning free of her ropes. A horrified Jimmy realizes that Castiel has returned and has gained Claire's permission to use her as a vessel. Using Claire, Castiel is able to smite a second demon fighting Dean and watches as Sam drinks demon blood and exorcises Amelia.

Castiel tells Jimmy that he intends to use Claire as his vessel and that Jimmy's work is done. But Jimmy convinces him to use him instead to protect Claire. Castiel leaves Claire and once again, uses Jimmy as a vessel, leaving Claire with her mother and no father again.
