What episode of IRIS mentioned iris? What do you mean?

Iris-Iris, Jin Xianjun's favorite flower in the original work, is called symbolism in drama, that is, symbolic suggestion. It is said that the name of this plant comes from the angel of God and the rainbow that connects the earth with other worlds (because this flower has red, orange, purple, blue, white and black, it deserves the name of the rainbow). The ancient spelling of French is fleur-de-luce, which means light and light in Latin. Therefore, this flower is a "flower of light" in French-the fate of Xian Jun, his love with Jin, his fate with Jin and his friendship with Jin are all shrouded in darkness, but these feelings are just a little light in the darkness; Iris also symbolizes the power of the royal family. It is said that when Clovis, the first king of the Frankish kingdom, was baptized (48 1-5 1 1), the five emperors gave him a gift-Iris (I believe this is the origin of the name of Iris organization in the play). Iris is also a symbol of religion-resurrection. Although there is only one life and God, it is the trinity of the Father, the Son and the Holy Spirit, so the atmosphere in the play is always shrouded in a religious atmosphere (tarot cards on Hungarian streets, Hong's cross flash drive, and Dr. Yu's "If someone bleeds, they will pay the price of blood" in Genesis of the Old Testament. Iris also symbolizes "Eve's tears"-so in the episode after Xian Jun disappeared, Cheng Xi mentioned iris.
