"When Claire Novak gets a lead on her mother, Amelia (guest star Leisha Hailey), who has been missing for years, Castiel asks Sam and Dean to help her," The CW said of the Robbie Thompson script. "Castiel feels guilty for what he did to the Novak family and 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."

Set to air on April 29, "Angel Heart" will come two episodes after Cas and Metatron's (Curtis Armstong) "Book of the Damned" search for Cas' grace, meaning everyone's favorite angel may soon be back to his pre-"Sacrifice" self.
