On this episode, Lee Young Eun found Teo that couldn't get on a motorcycle because of a cast on his arm. She couldn't just pass Teo and let him ride her car.
At this, she said, "Where is your house? I'll bring you home." At this, she didn't suspect Teo at all and took him to her house and treated him.
At this, Teo proposed, "Let's play a game and suggested a zombie game. After letting go of the cast, he put out a hand and said, "This could be the blindfold" and shook a bandaid in front of him.
Teo said to choose between a person and a zombie and smiled scarily saying, "People? I feel bad. If you were going to be a zombie, it'd be easier" and smiled. This is a scene where the psychopath Teo's scary face came out.
