The Legend of the Blue Sea Episode 18 Recap: Kang Seo Hee Arrested; Heo Joon Jae Abducted by Jo Nam Doo


In The Legend of the Blue Sea episode 18, twists have been shown. The episode started where it left off in the previous episode with Heo Joon Jae (Lee Min Ho) rushing to his father’s home.

In another scene, Heo Chi Hyeon was seen going to his stepfather’s room only to hear that he made a call to Joon Jae. He was devastated by it. Not a moment longer, his stepfather dropped the phone and died. He took care of the glass that triggered his stepfather’s death before he called the emergency hotline.

Chi Hyeon was interviewed and later the body was put in a stretcher. It was when Heo Joon Jae looked at his dead father’s face and broke down. When he found Chi Hyeon, he beat him up and threatened him. The police then stopped their fight.

Jo Nam Doo, Tae Ho and Shim Chung (Jun Ji Hyun) then went to the hospital. She comforted Joon Jae in his hard time. Later, Kang Seo Hee with Chi Hyeon were at the hospital as well, in front of the mortuary. She did a good job at playing a widow and cried a lot. Meanwhile, the police were searching the house with a warrant but they did not find anything.

Heo Joon Jae asked for an autopsy but the mother and son duo opposed to it. They said that Joon Jae ran away from home and never visited his father. They accused him of doing it because of the inheritance issue.

Chi Hyeon later on talked to Jo Nam Doo. He blackmailed Joon Jae’s friend. The latter agreed to do what the former wanted him to do.

Heo Joon Jae’s mother with her ex-employer went to the funeral. The two wives faced and confronted each other. Shim Chung was there when Kang Seo Hee was about to hit Joon Jae’s mother. She held the latter’s hand and peered into her memories, without erasing them.

After Joon Jae talked to Jo Nam Doo, Shim Chung arrived and told him what she saw in his stepmother’s memories. They went to his father’s house and together with the detective they searched for the evidence that was missed by the police. She led them to the basement and toward the secret room, where they found what they’d been looking for.

Because of it, Kang Seo Hee was arrested without warrant. However, she did not say anything that implicates her. She was released afterward.

With this, in a twist, a plan was concocted. Jo Nam Doo hit Joon Jae in the head and abducted him. He brought him to a place where the mother and son waited. There, Joon Jae got Kang Seo Hee’s confession. The police arrested her once again, now with a confession that she killed his father and was about to kill him, too.

Because Tae Ho found the CCTV footage wherein Nam Doo hit Joon Jae, Shim Chung and he went to follow Joon Jae’s location. There, they arrived and found that Kang Seo Hee got arrested. She was guided to the police car while Chi Hyeon took the policeman’s gun. He aimed it at Joon Jae. But Shim Chung ran to protect him. The episode ended with Chi Hyeon firing the gun.
