how did sam get out of lucifer's cage
Sam Winchester Almost a year has passed since Sam went to Hell, and he reappears to Dean after saving him from Djinn poisoning. Upon their reunion, Sam reveals that he has been back this whole time searching for whatever force brought him back and hunting with his mother's side of the family, the Campbells, led by their grandfather Samuel who was also resurrected.[47] While hunting with Sam again, Dean quickly notices how different he acts. These include using a baby as bait, allowing a child to go through a torturous treatment to gain information, and allowing Dean to become a vampire.[48][49][50] After facing the goddess Veritas, Dean and Castiel question Sam's behavior. Castiel then reveals that Sam's soul is not with him and is still trapped in Lucifer's Cage.[51][52] It is revealed that Crowley brought back Samuel so that they could help him find Purgatory, the afterlife of monsters, and that Samuel has been working for him. Crowley then states that if Sam and Dean help him he will return Sam's soul, but if they do not help him he will send Sam back to Hell.[52][53] Although Sam still retains his memories, likes, dislikes, and is capable of making rational decisions, he is completely without emotion and appears almost inhuman.[51][53]
