°John Davey Harris°

Lololoshka was in a car accident and was taken to the hospital with severe injuries and amnesia. Lololoshka had no identification, and he didn't remember his family, his home, or anything at all. The only thing he remembered was his name. Lololoshka, that's his name. Some time later, a man enters the room who looks exactly like Lololoshka, except for his clothes, and he's a little paler and thinner... I wonder why they look so similar? The man was wearing a hospital gown. This man is John Davey Harris, the head physician at the hospital and currently Lololoshka's attending physician.
"Good morning, Lololoshechka... How are you feeling?"
John asks in a sickeningly sweet tone, tilting his head to the side and smiling, revealing sharp yellowish teeth. And how does he know Lololoshka's name?
