Young-Roh presents both envelopes of bribery to Jang-Geum, and explains to Jang-Geum what they’re for and who they’re from. Jang-Geum asks why Young-Roh is giving her this information. Young-Roh says she doesn’t want to be a runaway the rest of her life and she can’t trust the other officer’s words. Young-Roh states she can trust Jang-Geum and asks Jang-Geum to help her become the next jae-jo sang gong, and in return Young-Roh promises to help Jang-Geum. Jang-Geum states she will not be involved in anything schemes and sends Young-Roh away.
Lady Choi arrives at the Kang’s place looking for Jang-Geum. Jang-Geum takes Lady Choi to her mother’s grave. Lady Choi kneels in front of the grave and apologizes to the deceased Myung-Ee, then asks Jang-Geum for forgiveness. Lady Choi turns to Jang-Geum, kneeling, and repeatedly asks Jang-Geum for forgiveness. Jang-Geum replies she believes the words of Lady Choi but she must go confess her mistakes to the court. Lady Choi begs she can’t do that or else her family will be doomed, but Jang-Geum states she must be responsible for her actions. That if a person loses nothing then she will not learn her lesson.
Young-Roh is missing from the palace. The Chois learn that she went to see the other officer and Choi Pan Sul sends his men to look for her all over the Hanyang city. Young-Roh is about to meet with the officer to confess to the court. When the officer turns away for a minute, the Choi Pan Sul’s assasin kidnaps Young-Roh and throws her into a isolated room. Choi Pan Sul and Lady Choi find the officer’s envelope on Young-Roh and asks Young-Roh to confess what the officer instructed her to do. Young-Roh confesses. The officer actually works for Oh. The Chois find out Oh is trying to destroy the Choi’s family for his own gain. Oh finds out Young-Roh has been kidnapped, probably by the Chois.
Under Lady Choi’s instruction, Young-Roh goes to the court to reveal dirty tricks of Right Prime Minister Oh. Lady Choi visits the mother queen. Oh sends a messenger inside to get Lady Choi but Lady Choi tells the messenger to lie to Oh and say she’s not there. Lady Choi reports to the mother queen that Oh has been planning activities against the court and states he’s unfit to manage the various departments including the house of medicine.
Choi Pan Sul sends Young-Roh away with a man as her escort. On her journey Young-Roh begins to sense danger. Min Jung-Ho tells Jang-Geum that Young-Roh has been arranged to leave the palace by Lady Choi. Jang-Geum gets worried and states Young-Roh is under danger. Min Jung Ho says he’ll look into it right away.
Oh tries to clear his name in front of the court official. Min Jung-Ho arrives saying Yoon Sang Gong (Young-Roh) has died. Lady Choi tells the mother queen that Lady Yoon (Young-Roh) has died and surely she was murdered and suggests it may have been Oh. Lady Choi further reports Jang-Geum has a letter from the dead head doctor. Lady Choi wonders aloud what would happen if the letter got into the hands of Oh and lady queen.
Yun-Saeng weeps at the news of Young-Roh passing away, and remembers the days when they were young as kitchen maids. Chan-Ee and Lady Min arrive and tell Yun-Saeng that Young-Roh went to see Jang-geum the night before and wonder if Jang-Geum could have prevented Young-Roh’s death. Lady Choi explains to Geum-Young that she had no choice but kill Young-Roh since it’s her job to protect the Choi family. Lady Choi instructs Geum-Young she must be the next one to protect the family.
The king visits Yun-Saeng and senses her sorrow. Yun-Saeng begs the king to grant Jang-Geum’s wish or else more lives will be sacrificed. The king states the matter concerns many people and if it doesn’t go right Jang-Geum’s life could be further endangered. Yun-Saeng tells the king Jang-Geum has a proof of conspiracy, which is a letter the head doctor left for her before he suicided. The king orders the head escort to retrieve the letter from Jang-Geum. The lady queen who is present is surprised by the news of a letter. Jang-Geum is called by the mother queen. The mother queen demands the letter from Jang-Geum. Jang-Geum replies she doesn’t have it. The mother queen turns to Lady Choi and asks what she’s up to.
Lady Choi goes back to talk to Geum-Young. Lady Choi figures out Yuh-Ri must have the letter since it’s unlikely that the doctor died without leaving his words. Sir Shang Shan asks Jang-Geum to present the letter to the king. Jang-Geum replies she doesn’t have it, she made it up and she’ll clear it in front of the king herself.
Lady Choi calls Yuh-Ri and orders her to fake the letter and present it to the court. Yuh-Ri is reluctant but Lady Choi states if she doesn’t, she’ll tell everyone about Yuh-Ri poisioning lady sook-won (Yun-Saeng). Jang-Geum finds out Yuh-Ri has a letter and runs to Min Jung-Ho with the news. The king finds out a letter has turned up and tells his head guard he wants to read it.
Oh is taken to the investigation officers. The investigation head tells Oh according to the head doctor’s letter, Oh instructed him to put something in the king’s food. Oh laughs at the accusation and points to Lady Choi as the true culprit who also killed Lady Yoon (Young-Roh) and probably the one who told medicine woman Yuh-Ri to write up a fake letter. Just then the head guard arrives saying the king wishes to read the letter and has summoned all parties involved to show up before him, including members of the medicine house and the royal kitchen.
At the meeting the investigation officer tells everyone the letter accuses Oh but Oh accuses Lady Choi, so everyone must re-tell their story to see where the differences lie. Lady Choi defends herself saying at the time the king become ill at warm springs, she was sent to Peach Hall as a punishement and ordered by Lady Han to not step out of Peace Hall without permission. Lady Choi raises her voice to point the fault at Oh and tells everyone not to question the last words of a deceased man.
Then, to everyone’s shock, the supposedly dead head doctor shows up, accompanied by Min Jung-Ho and Jang-Geum.
