Yuh-Ri goes back to nae-ee-ohn and she’s told teacher Doctor Shin wants to see her at lady sook-won’s room. Yuh-Ri arrives and sees all the doctors and nurses examing Yun-Saeng. The other nurses report to the doctor their finding which agrees with Jang-Geum’s, not Yuh-Ri’s.
Lady Min asks what’s going on. Doctor Shin asks Lady Min what lady sook-won’s been eating. She reports shrimp and lots of greasy food Yuh-Ri ordered. The staff go back to nae-ee-ohn. Doctor Shin demands Yuh-Ri to explain why she ordered such health-deprivating food for lady sook-won. Yuh-Ri insists she didn’t know it was harmful since she diagnosed Yun-Saeng differently. Doctor Shin and Doctor Jung don’t believe Yuh-Ri because she’s very skilled and she couldn’t have not known so they ask her what her real motive is. Yuh-Ri continues to say she’s innocent and the head doctor bails her telling the staff to forget the incident since Yuh-Ri made an honest mistake.
Alone, Yuh-Ri confronts Jang-Geum. Jang-Geum tells Yuh-Ri that Lady Jung and Lady Han will not forgive someone who uses food to harm people and neither will she. Jang-Geum warns Yuh-Ri if she let’s this happen again she will not be forgiven. Jang-Geum gives detailed instructions on how to take care of Yun-Saeng to Lady Min and Chan-Ee, and tells them Yuh-Ri is Lady Choi-sg’s spy.
Jang-Geum goes to see Min Jung-Ho to update him on Lady Choi’s activities. Jang-Geum states she wishes to look into the incident that caused the king to faint, which eventually led to Lady Han-sg’s jailing and death. Jang-Geum believes Lady Choi and Right Prime Minister Oh were behind the reason and she wants to dig out the truth to prove Lady Han’s innocence. Min Jung Ho says that’s impossible since she can’t examine the king’s health as a woman nurse. Jang-Geum says there is a way, which is to look into the king’s health records which can only be accessed by the king’s closest servants.
Jang-Geum goes to see the head guard who told her he can help her whenever she needs help. She asks him to help her get to the records but he says that can’t be done since those are sacred. Lady Min gets a blessed shirt for Yun-Saeng from the Kang Duk Gu and wife so Yun-Saeng will have a smooth labor. Jang-Geum goes to see Doctor Jung for permission to enter the sacred room where the health records of the royal family are kept, with the excuse that she wants to look into the background of the lady queen, just to make sure she’s giving her the best care. But Doctor Jung says that’s not necessary.
Lady Choi tells Geum-Young to decide how to deal with Jang-Geum. Jang-Geum tells the lady queen she has a request. The nae-ee-ohn staff find out Jang-Geum asked the lady queen for permission to go inside the sacared room and gets upset since the room is forbidden to someone at Jang-Geum’s ranking. The doctors tell Jang-Geum to withdraw the request from the queen. Jang-Geum asys she can’t and begs them to allow her to go in just this once.
Jang-Geum arrives at the record room. At first the guard forbids her from entering but the officer inside says to let her in since she got permission from the lady queen. Inside, the officer tells Jang-Geum she is only allowed to look at the lady queen’s records and she is not allowed to take anything from the room. Jang-Geum steals the king’s record book and runs back to nae-ee-on. Just as Jang-Geum is about to pull the stolen book from her stockings, Yuh-Ri arrives asking what she’s doing. Jang-Geum leaves and brings the book to Jang-Duk. Jang-Duk copies the contents of the book so Jang-Geum can return the original to the record room tomorrow.
Next day Jang-Geum brings the book back and steals another one so Jang-Duk can copy it and study it.
Geum-Young goes to see Min Jung-Ho and asks him to see her in private. Geum-Young brings him to the room where she prepared food and wine for him. Geum-Young tells him she always wanted to do this for him and asks him to remember her as the palace maid who was forbidden to love him but could not stop caring for him. Geum-Young states tomorrow she must put a stop to all her lingering love but one thing troubles her heart which is that she was never able to serve him food, and begs Min Jung Ho to eat.
Jang-Geum sneaks the last record book to Jang-Duk who tells her she’s making progress in determining what may be the real cause of the king’s illness at warm springs. The king is sick. The head doctor of nae-ee-ohn examines him and discovers a cold sore in the king’s mouth. When alone, the head doctor suddenly remembers something about the king’s health and goes to the record room to look up something. After the head doctor leaves, the guards from the record room tells the doctor to follow them. Then Jang-Geum arrives at the record room to put back the last record book she stole.
After she leaves, the guards from the record room catch up to her and takes her to a dark room to ask her to confess her reason for stealing the king’s record books. Jang-Geum tries to deny it, but the guards say the record book was missing from the time the head doctor was at the room but it reappeared after Jang-Geum arrived so she is definitely the one who took it.
Head doctor tells Lady Choi about Jang Geum being under investigation. Lady Choi suspects if Jang-Geum’s trying to look into the king’s faiting incident and orders Young-Roh and Choi Pan Sul’s messenger to investigate further.
The palace head guard tells Jang-Geum she should’ve listened to him when he told her not to go into the record room but Jang-Geum begs him saying the matter is not only about Lady Han’s innocence but it also regards the king’s health.
The head guard tells the other guards Jang-Geum made the mistake due to her over-blown curiosity. The guards let her go and Jang-Geum is escorted out by the head guard. Lady Choi catches up to the head guard and Jang-Geum, and asks the head guard if he wants to betray the king.
