Kim Jo Nyeon says if someone doesn't properly handle the precious colouring powder and ruins it, the colouring process may not proceed and the painters cannot complete the royal portrait. Jang Byeok Su's face brightens on hearing this. Young Bok, enduring the danger of breathing toxic gas for Yoon Bok's sake, makes colouring powder. Watching this, a disgruntled worker asks why Young Bok isn't doing wood painting and assigns him the work that has gotten behind.

Seeing the ruined colouring powder, Hong Do breaks the rule, which restricts leaving the palace during the painting of the royal portrait, and goes outside to retrieve the colouring powder.

King Jeongjo asks Hong Do to trust him and to do as he says, though they cannot know what the ministers may attack when the royal portrait is complete. King Jeongjo gazes warmly at Yoon Bok mixing the coloring powder when Yoon Bok says his older brother, who was sent to Dancheongseo, made it.
