Master Lee explains that some are born able to grasp energy and others fear them, as Uk catches the Golden Fish and Mu-deok tells him he has reached Chisu.
Uk fights Yul using spells copied from his earlier duels, loses, and still stuns everyone by using Tansu, proof that he has reached Chisu.
Asked why Master Lee helps him, Uk 'reveals' the family matter: Lee is winning over Maid Kim, and Uk offers Park Jin the first chance.
Uk complains he cannot visit Mu-deok; Yul has him call the homing bird with a whistle and asks what the bet with the Crown Prince was.
Mu-deok confronts Uk about the rumor and dares him to embrace a pretty lady; he takes her at her word, and later she brings him something she found.
At the palace the King rants about Shaman Choi, then Master Lee reveals his soul is over a century old in a borrowed body; Mu-deok seeks the broker.
Uk grasps what Master Lee's ability means for Mu-deok, as the search for the broker ends in an accusation of murder.
Master Lee says soul shifters look like anyone else and only fear reveals them, then offers the King a gift: a dog.
Ordered to kill the 'wily beast', the guards attack Uk; Jin Mu joins in until the King orders everyone to stop.
Master Lee says the soul shifters showed themselves through fear; Uk, hurt in the fight, fusses over the dog while Yul wonders what Lee knows.
Over tea, a rumor about Naksu's new body leads to an argument over whether ordinary people are foolish or simply frightened.
Heo Yun-ok arrives to tend Uk's wound while the others gossip that Heo Yeom wants a grandson-in-law and Uk tops her list.
Uk is taken to Songrim and confined; Dang-gu insists Mu-deok could not kill, while Yul examines the bodies and weighs what he knows.
Park Jin tells each that the other confessed their secret; they must guess what the other said, or one of them dies.
Both told Park Jin they love each other; Uk teases Mu-deok, she orders him to choose life over love, and he refuses.
Uk teases Mu-deok's glare and coaches her on sweet eyes; she asks what their future holds, then reveals Master Lee's dog was really Gwigu.
Mu-deok realises the dead dog knew she was a soul shifter all along and kept quiet; then word spreads that Dang-gu and Cho-yeon are lovers.
Summoned by an absent Master Lee, Uk receives Naksu's sword along with a scolding about leading Yun-ok on and a warning about how strict Lee can be.
Master Lee's message is a threat; Mu-deok says once she is Naksu again they part ways, and Uk asks to be her first target if she draws the sword.
Uk worries So-i knows who Mu-deok is; meanwhile So-i, sure everyone who knew her is dead, rehearses being blind with an umbrella for a cane.
Drinking together, the three friends retell how they hid a broken inkstone as boys, and discover Dang-gu romanticised how they got caught.
The friends notice Yul is not sleeping; memories of Gwigu's body suggest he is quietly carrying something he will not say.
Remembering Eunuch Kim's words, they wonder if the Queen is a soul shifter, and work through the Seo family's Lanterns of Life.
Both hunting Eunuch Kim's trail among the shamans, Uk and the Crown Prince haggle over information, the prince pulling rank every time.
An old shaman who reads Uk and the Crown Prince as suspiciously close recalls a hex-casting shaman who leapt into a fire while fleeing Jang Gang's mages.
Sworn to secrecy about Jang Gang's past, the pair realise someone is following them and separate to flush out their pursuer.
In Gaema Village a man who recognised Jang Gang's sword calls him a madman; Uk explains why he still carries it, and the stranger recalls Do-hwa.
Hearing Uk is after Shaman Choi, the stranger warns that sorcery's darkness consumes the soul, then admits he is damaged to his core.
Uk tries on trinkets, then puts makeup on Mu-deok, insists she is blushing, and teases that she looks like a drunk dog.
The friends realise the returned daughter carries the umbrella Yul gave So-i; Mu-deok grills Yul like a jealous wife before Uk takes over.
