A Songrim elder tells a boy how a hailstone that never melted produced the Soul Ejector, plunged Daeho into war, and why Jinyowon's relics are feared.
Brooding over Mu-deok's refusal, the Crown Prince finds her in his chambers, but she smells wrong; he unmasks the visitor as something wicked.
The Crown Prince is told the maid broke the yin-and-yang jade meant for the wedding rings and fled, then Yul turns up looking for her too.
An apparition of Mu-deok tells Yul he kept the whistle and never stopped longing for the girl from Danhyanggok, then dares him to banish her.
At Songrim, the talk turns to Gwigu's origins and to the only way souls can be shifted without Hwansu: the ice stone is back in the world.
Uk takes responsibility for his maid before Jinyowon's leader, wins permission to search for her himself, and asks to enter the relic vault.
Warned the vault's relics can trap anyone forever, Yul and the Crown Prince insist on going in with Uk, and are given one hour.
The Crown Prince teases Uk about inheriting Jinyowon's treasures, a noise startles them, and calm Yul marches off the wrong way.
Locked up, Mu-deok rattles Cho-yeon with a superstition about broken jade, then accuses her of framing the maid; Cho-yeon threatens to sell her.
Comparing notes on the illusion, the Crown Prince learns the sachet he gave Mu-deok has been put to use keeping flies off the outhouse.
The broken mirrors lead them to the Mirror of Longing. Its leader refuses even a royal order to move it and vows to seal the door on Uk.
Inside the mirror, a reflection argues that all self-image is illusion and asks for her energy; Mu-deok turns its logic on it, then hears Uk calling.
As the door is about to be sealed, Yul is sent to drag Uk out while Uk tells the mirror his plan to keep her by his side, and that he misses her.
A memory of Uk carrying her up a tree, a spirit's cry about the blind girl and the ice stone, and the mirror bursts apart.
Cho-yeon claims the broken jade, the damaged mirror and the sealed door as her own doing, and the family agrees to keep it quiet.
Uk ties a cloth over Mu-deok's dazzled eyes, then Dang-gu, Yul and the Crown Prince each arrive offering to take her for treatment.
Maid Kim asks if he would lock her in like Jinyowon's leader; he will not lie to her, and only admits too late how it would break his heart.
Scolded for entering Jinyowon, Uk uses the mirror's lesson on illusion to explain why he will stop proving himself and find his own path.
Mu-deok insists she broke the mirror with her own returning power and lectures Uk that a pupil should die for his master; he sets terms of his own.
Calling the match a marriage of convenience, Uk admits the rumor he is not Jang Gang's son and asks her to weigh that risk.
The Cheonbugwan Assistant Gwanju, scorned by his half-sister, urges her to cancel Uk's marriage and promises the Crown Prince and help finding Bu-yeon.
Piecing together the illusion's words and memories of Danhyanggok, Yul concludes the shifted soul in Mu-deok is Naksu and that she is alive.
Uk gives Mu-deok a token made from the yin-and-yang jade as a reminder to stay loyal, unaware she was ordered to hand him over; she announces she is leaving.
At Cheonbugwan, Songrim's leader hears that Naksu's father was a soul shifter and is shown the hidden star plate from the night Jang Uk was born.
A mage threatens to expose Naksu unless she brings Uk for his soul to take; she waits out the clock and learns he alone knows her secret.
Uk follows Mu-deok even after learning she meant to hand him over, and takes on the mage in a downpour until the alchemy of souls strikes.
