Shi-on notices that a child who had surgery for a choledochal cyst is in danger and takes him into the OR without authorization; Do-han's team is in the OR for another operation and ends up operating on two patients simultaneously.

The residents of pediatric surgery resent Shi-on for causing Do-han trouble, so Yoon-suh pulls him aside and advises him; Do-han runs out of an ethics committee meeting because a child is in critical condition.

Shi-on keeps getting himself in trouble and ends up being hated by the children at the hospital except for In-hye; a child with intussusception comes in and because Do-han is serving his suspension, Yoon-suh must take lead for the first time.
