Charles brings home a doctor and family friend, who offers Andy a checkup at the house. He later tells Charles about the truck driver and says he needs to inform the police about the suspicious coincidence of Andy's return. Andy visits him at his office in the middle of the night demanding a checkup, but the doctor can't detect a pulse or heartbeat. Andy tells him, "I died for you, Doc. Why shouldn't you return the favor?" He attacks and kills the doctor, then uses a syringe to inject the doctor's blood into his arm. It's clear that Andy is some kind of vampire or zombie who needs the blood of others to reinvigorate his decaying body.
