On the night Do-hwa dies, Jang Gang arrives, blocks the baby's gate of energy and forbids anyone from ever opening it.
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.
His friends explain to Mu-deok that Uk's gate of energy is opened just enough to keep him alive, and no one in Daeho may open it.
Mu-deok brings tea to the punished Uk, thanks the first person who ever tried to save her, and promises to spare him.
With firecrackers bought on Uk's name, Mu-deok has Ju-wol find a black-market buyer for the Spirit Plaque and orders more chicken.
The king considers promoting Jin Mu for killing Naksu's men; Songrim objects, and Jin Mu asks to burn Naksu's body and keep her sword.
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.
Mu-deok's Spirit Plaque bait draws Cheonbugwan mages, who kill the woman who stole it, mistaking her for Naksu. The Danju has cut her off.
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.
Uk collapses; the only cure is to open his gate of energy. Mu-deok is tortured but keeps silent until Master Heo opens it.
Uk wakes with his gate of energy open, finds the beaten Mu-deok, and the two finally become master and pupil.
