On The Jonathan Ross Show this week, Gavin and Stacey star and co-writer Ruth Jones, the stars of the new comedy horror Ready or Not 2: Here I Come, Buffy the Vampire Slayer herself Sarah Michelle Gellar, and Ant-Man and the Wasp: Quantumania star Kathryn Newton, comedian, writer and director Richard Ayoade, This Morning and Bake Off presenter Alison Hammond, and one of the country's most exciting new bands The Molotovs will be performing in the studio.

After the massacre at the ranch, Dean, Sam and Castiel double their efforts to find a cure for the Mark of Cain but there is nothing in the lore that can help them. Desperate, Castiel comes up with an idea that Sam deems the “single worst idea I’ve ever heard.” Meanwhile, Rowena continues to plot against Crowley, and Castiel tries to mend his relationship with Claire who is plotting revenge against Dean for killing her friend.

When Claire Novak gets a lead on her mother, Amelia (guest star Leisha Hailey), who's been missing for years, Castiel asks Sam and Dean to help her. Feeling guilty for what he did to the Novak family, Castiel wants to make amends by reuniting Claire with her mom. However, when they find out what took Amelia, they realize there is a chance Claire may not get her happy ending.

Castiel finds (his vessel) Jimmy's daughter Claire Novak (guest star Kathyrn Love Newton) in a group home and she convinces him to break her out. After she runs away from him, Castiel calls Sam and Dean to help find her before she gets in trouble. Meanwhile, Crowley faces his biggest challenge yet.

Sam and Dean drop in on Jody Mills (recurring guest star Kim Rhodes), Claire (recurring guest star Kathryn Love Newton) and Alex (guest star Katherine Ramdeen) after receiving a panicked phone call from Claire. She believes the recent murders in town are supernatural and wants the boys' help. However, Sheriff Mills tells Sam and Dean that Claire has been getting into trouble lately as she's been attacking normal people and accusing them of being monsters.

Sam & Dean let Mick Davie (guest star Adam Fergus) s tag along on a case as they search for a werewolf. The three men run into Claire Novak (guest star Kathryn Newton), also working the hunt. However, the reunion is short-lived after Claire is bitten and the Winchesters race to find a way to help her before she turns.
