Dean and Sam return to their motel room to find Castiel and Uriel waiting. Sam is thrilled to meet Castiel. Castiel acknowledges Sam as the the 'boy with the demon blood' and says that he is glad Sam is no longer using his powers. Castiel reveals they found a hex bag, which would've killed the boys, secreted in the room and that the raising of Samhain by the witch will break another of The 66 Seals. He advises Sam and Dean to leave town because he and Uriel are going to destroy it. Sam and Dean argue that they can find and kill the witch and stop the summoning of Samhain.

Later, Uriel expresses his contempt for humans and tries to persuade Castiel that they should destroy the town anyways. Castiel reminds him that Dean was saved because he has 'potential', and that they must follow their 'true orders'. After Sam has used his powers to send Samhain to Hell, Castiel appears to Dean. He reveales that their true orders were to follow whatever Dean decided to do, as a test under "battlefield conditions". Dean, thinking he has failed, asserts that he'd make the same decisions all over again if he had to, because of what he and Sam have saved. Castiel confides that he was praying Dean would choose as he did, and also that he has questions and doubts about the plan from Heaven. He warns that in the coming months, there will be more hard decisions for Dean -- and the angel does not envy him that.
