The King is convinced that the Crown Prince should take his place, just as the appeal requested. The Crown Prince, however, realizes that he's been framed and decides to prostrate before the king and ask for reconsideration. Prince Milpoong has a further plan that will bring down the Crown Prince and he's waiting for the right time to implement it. The Disciples ask the Queen Dowager to persuade the king not to blame the Crown Prince.

The special judiciary agency is opened to investigate the Crown Prince's involvement in treacherous plottings. Wi Byeong Joo was being interrogated but is released and takes charge of the treason case. Dal Moon is now working for Prince Milpoong. He spreads rumors in the city saying that the Crown Prince isn't the late king's son. Moon Soo and his colleagues find evidence related to Wi Byeong Joo's coverup of Han Jeong Seok's murder.

Wi Byeong Joo set up a treason case, accusing the son and grandson of two Disciples officials for plotting against the king. The Crown Prince visits Min Jin Heon privately and asks him to side with him for the time being instead of supporting Prince Milpoong. The Crown Prince notices that the posts that were put up around the city contain a secret message from Dal Moon. The king decides to question the alleged rebels themselves but Min Jin Heon intervenes.
