Episode 3 of Connect starts on the rooftop after he pushed Muyung-hoon off the ledge and killed Sun-hee by breaking her neck.
Jin-seop attacks the doctor and asks him questions about the eye. Yi-rang is sure that the murderer has found out about the connection but Dong-soo is not sure about it yet. She hears one side of the conversation and learns that the new owner of the eye, aka Jin-seop was soon going to die. The gangster that the cops released goes back to his group but Detective Park is on the lookout for him. Yi-rang claims that Jin-seop had the power to make his life hell and kill him by revealing his identity online. Outside the store, he suddenly makes a connection with Jin-seop again and this time it is Jin-seop who was purposely watching the video. He explains to Yi-rang how the corpse artist has his other eye and that he could see out of it at times. They ask Jin-seop about his coat and Ji-young intervenes asking the cops to look for Dong-soo instead of questioning the innocent employees. Detective Choi asks where Jin-seop was during the incident and he claims that he watched Dong-soo from the hallway. They ask him about Dong-soo and he recalls how he had made a ruckus on the day of the incident. Jin-seop has taken the stairs to the bottom but he is shocked when he overhears footsteps from the bottom coming upwards. Dong-soo makes his way inside the building and Yi-rang is confused about what just happened.
