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. false 2015-01-28 15:21:52 John Badham Brad Buckner Eugenie Ross-Leming Brad Buckner Eugenie Ross-Leming 7.5 2005 TV-14 43 The CW /config/data/metadata/library/bb/bbc7120b73e5b74d67a531ae00b92d1f/poster.jpg Ruth Connell Actor 0 Kathryn Love Newton Actor 1 Jensen Ackles Dean Winchester Actor 0 Jared Padalecki Sam Winchester Actor 1 Misha Collins Castiel Actor 2 Mark Sheppard Crowley Actor 3 Jim Beaver Bobby Singer Actor 4 /config/data/metadata/People/J/Jim Beaver/folder.jpg Ty Olsson Benny Actor 5 Mark Pellegrino Lucifer Actor 6 /config/data/metadata/People/M/Mark Pellegrino/folder.jpg Jeffrey Dean Morgan John Winchester Actor 7 /config/data/metadata/People/J/Jeffrey Dean Morgan/folder.jpg Lauren Cohan Bela Talbot Actor 8 /config/data/metadata/People/L/Lauren Cohan/folder.jpg Katie Cassidy Ruby (1) Actor 9 /config/data/metadata/People/K/Katie Cassidy/folder.jpg Alona Tal Jo Harvelle Actor 10 /config/data/metadata/People/A/Alona Tal/folder.jpg Osric Chau Kevin Tran Actor 11 Felicia Day Charlie Bradbury Actor 12 /config/data/metadata/People/F/Felicia Day/folder.jpg Genevieve Padalecki Ruby (2) Actor 13 /config/data/metadata/People/G/Genevieve Padalecki/folder.jpg Samantha Ferris Ellen Harvelle Actor 14 /config/data/metadata/People/S/Samantha Ferris/folder.jpg seriesHd4tb 10 10 2015-01-20 0.000000 0 5040751 http://thetvdb.com/banners/episodes/78901/5040751.jpg
