Back at home, Ha-ru’s aunt revealed why she lied to her about what happened the night his parents were killed. She wanted to protect him. The suspicious paper is the known doctoral submission made by Dr Park but the name on it was Ha-ru’s father.

Dr Park loses it and tries to kill Ha-ru but Ha-ru can defeat him and hold the knife to Dr Park’s throat.
At the hospital, Dong-woo seems overly excited about the turn of events. He is convinced that Ha-ru cannot contain his brain and will also become a killer.
Bac at the remote scene, Ha-ru holds the knife ready to stab Dr Park who still argues that he was not the killer but tried to kill Ha-ru since he would make known the secret that he knew about the killer but decided to turn a blind eye. He says that Dr Hwang blackmailed him with fake evidence and he had come to get rid of it. Detective Guem who is at the scene tries to plead with Dr Shin. Ha-ru remembers Dr Hwang’s words that he wants him to become a murderer. He lets go, Dr Park.

Ha-ru and detective Geum visit his childhood home and meet Dr Hwang just as he walks in. They manage to break in and Ha-ru realizes that the house is still the same. Don-woo must have bought it before he was sent to prison.
