One year ago : Sam and Dean had gone hunting, a very hard hunt but they could not refuse because many people feared for their lives. Unfortunately during the hunt, they were injured and separated. Dean lost Sam and can’t find him. He constantly tries to call him in vain. Sam was found unconscious on the edge of a river for Y/n. A witch. She decides to pick him up and take him home to treat him. Sam is in bad condition and Dean is scared to death as he searches for him throughout the forest, also injured. He eventually collapses against a tree, exhausted and losing blood.
