The police officer, Gu Dongxu, arrives at the hospital, where he is being treated for his injuries. He tells the doctor, Dr. Song, that he was in the car with his friend, the police officer's uncle, when he was hit by a speeding car. He asks the doctor if he has sent someone to watch him, and the doctor tells him that he has. The doctor tells Gu that his mother and his brother-in-law are half- siblings, and that Gu's father is his third wife. Gu says that he does not know what the last sentence means.
