Extended data:

Dean Winchester

Winchester brothers, a fierce and fearless man. Cherish my impala, like rock, movies, food, beer, hot beauty. I am brave, but I am only afraid of flying. On the surface, Dean is cynical and keen to talk about things around him, but his heart is lonely and desolate, with love and nostalgia for his parents, too many heavy responsibilities and pressures, and a family mission.

In order to fulfill my father's last wish, I gave up my dream and a quiet life. I am willing to give everything for my relatives and friends. Dean loves his relatives and friends the most, hates all demons that hurt people around him and angels that threaten the two brothers, and doesn't believe in any demons at the same time. He once exchanged his life with the devil at the crossroads to save Sam, who died unexpectedly, fell into hell and was in great pain, and was rescued by Cass.

Sam Winchester

Winchester's younger brother, born six months ago, was blended into the demon's blood by the yellow-eyed demon. I quit ghost hunting in high school because I didn't want to take the road arranged and controlled by my father.

When he was about to enter law school, his brother asked him to look for his missing father together. When he came back, he found that his girlfriend had been killed by the devil who killed his mother. From then on, Sam devoted himself wholeheartedly to hunting. Fall into hell with Lucifer at the end of the fifth season. At the beginning of the sixth season, he lost his soul. At Dean's request, sleepy hollow Death brought his soul back.

Eight seasons tried to close the gates of hell by completing three trials at the cost of his life, but Dean stopped him. At the beginning of the ninth season, under the concealment of Dean, Ezekiel possessed Sam to repair the influence of the trial. In the tenth season, I am obsessed with finding a way to remove Dean's Cain seal, and finally I will work with Dean to remove the seal.
