Sorry about that teacher because I couldn't find a topic to write so I decided to write about again supernatural. It's last season finished two or three weeks ago but it will continue . The season final was really wonderful.At the beginning, dean's father's car is mentioned which is very important for them and will be a way to survive.Before season final, one angel tells them to remand lucifer his pit if they want to save the world so they search for how they can do that. Sam thinks that he can push him to his pit by accepting his willing and also he can resistance lucifer even lucifer  uses his body.They fiind this opinion logically but actually they have to do that owing to dean's deal with Death.Sam doesn't know this deal by the way. Because of this, Sam accepts Lucifer's offer and so lucifer comes body of sam in. He becomes more powerful after he got sam's body and unfortunately, sam can't resistance him.There is also michael who finds a body to fight his brother lucifer.

At final, lucifer and michael meet and speak about God and Lucifer tells not to fight but michael objects to this opinion and tells him that he is not bad son and will fight for his father.At that time,dean comes the place where they are.He wants to speak sam and castiel also comes to prevent fighting so he sends michael away for a short time.this makes lucifer angry and he kills castiel and hammers dean very bad.While he was beating him, he shoots dean to car.He comes near dean and due to reflecting his memories of car's light.He stops beating his brother.Michael comes and Sam collects himself. He pushes michael and they jump pit together. Ohhhhh. Castiel returns and makes dean healthier .Dean loses his brother and goes to his love to have good life with her and their son.At the very final, while they are having dinner, one person seems under the street lamb. They show that this person is Sam!!!!!! He was looking his brother like angry but this is my opinion because I made this inference from sam's look which is behind.
