"Good Doctor" Genuis Joo Won serves as a human ultrasound and saves two lives.

September 10, the 12th episode of the KBS drama "Good Doctor" featured the life and death situation of a pregnant mother and her baby during a critical surgery.

Kim Do Han (Joo Sang Wook) faces the situation where he must give up on the baby in order to save the mother. Kim Do Han knew that both the mother and the baby could die.

However, Park Si On (Joo Won) remembers his brother and says, "We have to save both of them. The person who is left is going to be sad. If you think about it both people each have 50% chance of surviving."

Kim Do Han changes his strategy. Kim Do Han however, does not have enough time to use the ultrasound machine so he tells Park Si On, "Touch the baby and figure out where the organ is." Park Si On closes his eyes and does exactly what he is told.

After working together as a team, Kim Do Han and Park Si On complete the surgery successfully.
