When the doctor arrives, he is shocked to find that the patient has been given a lethal dose of a blood-boosting drug. He is also shocked to learn that the drug has already had a negative effect on the patient's heart rate, blood pressure, and breathing. The doctor explains that the side effects of the drug have already begun to show themselves, and the patient coughs. He also learns that the pregnant woman has already been injected with the drug, and that the pregnancy has been normal. He wonders if this is the real experiment being conducted by the 731, the human experiment laboratory. He then hears the sound of a chain pulling away from the ground, which he thinks is the same sound he heard when he was in the police station.
