'He is Psychometric' week 3 review: Lee Ahn and Jae-in partner up while Kang Seung-mo faces his past

In 'He is Psychometric' over the last two episodes, Lee Ahn (JinYoung) and Yoon Jae-in turn (Shin Ye-eun) turn over a new leaf as the two begin to work together to make Lee Ahn a better psychometrist.
In the third week, a lot about Lee Ahn's adopted brother Kang Seung-mo (Kim Kwon) was revealed in bits and pieces as a flashback about his mother and an assailant in their life, assumed to be his father. It is also possible that this man is a suspect in the fire at the apartment where Lee Ahn lived as a child, and recently, two years ago - another fire accident at a hospital. Lee Ahn, who notices a strange delivery truck following his brother on his way to work, follows the truck and ends up being stabbed by the assailant. He, however, manages to get a read on the assailant and realizes that the man has been following his brother for a while now.
