Fed up with sharpening swords and never learning a spell, Uk walks out on Monk Ho-yeong, and answers an insult about his birth with a creditor's threat.
Mu-deok learns of the four famed young heirs of the Jin, Park, Seo and Jang families, and quietly swears they will all die.
Dang-gu tracks down Uk, who wants his friend to crack crab shells with a spell, and shares a rumor that Naksu may still be alive.
Caught stealing jewelry when Ju-wol realizes she can see, Mu-deok flees across the roofs and crashes into Uk, who praises her eyes and hands her his plaque.
Uk asks about Naksu's sword technique; Dang-gu explains Tansu, and Uk realizes the girl went for his vital point in one move.
Uk sends Mu-deok back and forth: too hot, too cold, smelly water, bad food, the wrong blanket.
Swearing Uk will be her first victim, Mu-deok wishes for a scrap of her old power, something stirs, and suddenly his bath is just right.
Unable to draw his father's sword because of the spell on him, Uk is told no one will open his gate of energy, and vows to find a master himself.
Hunting for the Spirit Plaque, Mu-deok hides in Uk's bed, claims she was warming it, and fears he wants her there all night. He only wants the brazier.
Uk shows Dang-gu the bird whistle found on an unexpected person and insists he remembers exactly who he gave it to.
Uk finds Mu-deok in the chaos, says her eyes gave her away, and wants the soul-shifting assassin to break his spell and teach him. She spares him.
After twelve failed masters, Uk explains how he knew her: the blue mark is in her eyes. He offers to hide her if she plays his servant.
Yul's blade finds the pair; Uk passes Mu-deok off as his maid, she grips the blade to protect him, and Uk scolds her glare.
Naksu's body is gone and a spy is suspected; Uk teases Mu-deok while the others discuss how soul shifters pick similar bodies.
Where her body was kept frozen, Uk names Mu-deok as the Shadow Assassin, laughs off a crush, and asks her to break his spell as his master.
Mu-deok refuses and threatens to kill him; Uk reveals they are sealed in Songrim's secret room, so she needs him to get out.
Mu-deok admits she needs her sword's energy to open his gate, Uk turns out to have lied, and both end up clinging to each other on a trap floor.
Everyone in Songrim is gathered and locked in while Jin Cho-yeon brings Gwigu, the Jin family's ghost dog that sniffs out sorcery.
Gwigu circles the room as Mu-deok waits to be exposed beside Uk, then lunges at another man who is a soul shifter and petrifies.
The Four Seasons are together again for the first time since Uk and Cho-yeon called off their wedding, and it shows.
Uk catches Mu-deok slipping away, warns her about her glare, and leans in to show when the mark in her eyes becomes visible.
Gwigu turns up, Uk tells Mu-deok to run, and Cho-yeon finds her family's heirloom pottery smashed in his hands.
Mu-deok learns he broke the pottery to save her; the Songrim leader confronts Uk and forbids him from moving or speaking.
Mu-deok brings tea to the punished Uk, thanks the first person who ever tried to save her, and promises to spare him.
Uk claims the sword in his father's name; Jin Mu says an ordinary man cannot even draw it, and Uk lets a pointed 'for now' hang.
As Naksu's body burns before Cheonbugwan, she recognizes the Danju as Jin Mu and remembers the fire that took her family.
Uk brings Naksu's sword, but Mu-deok cannot pull it free; he tells her to live as Mu-deok, she says she would rather die, and he lets her go.
Mu-deok stands at the soul shifters' grave by the lake calling it hers too; Uk hears she headed for the lake and runs there shouting her name.
Uk got her treated and given eye drops; Mu-deok realizes the lake restored her power, so she needs someone with energy that strong.
She asks Uk to risk his life for her once more, gives him a poisonous herb, and promises to be his master if he survives.
