Bu-yeon apologises to the unconscious Yul, sees a strange memory of Danhyanggok, and clashes with Young Lady Heo over a sealed letter.
Uk tells Bu-yeon to stay out of it; she says Yul is her friend too and she will help until the end.
A warning about pregnancy sends Dang-gu into a panic; Bu-yeon volunteers and flatly insists there is no chance for her and Uk.
Heo Yeom draws Yul's last energy into the wick and places it in Bu-yeon's mouth; she must not open it before time runs out.
At Jinyowon, Go Won meets the shaman he knew and learns she is Jin Bu-yeon, and that Jang Uk is the husband she complained about.
Uk and Go Won use the gold's energy at the fire bird's barrier to pull the parasite from Bu-yeon, then race back to revive Yul.
Bu-yeon says she is going home of her own will; Uk claims he has no use for her, and her parting jab stings.
Uk replays her parting words, finds the lantern she gave him, and remembers her turning off the last lantern.
Yul learns So-i died and the parasite is gone, and apologises to Bu-yeon about Danhyanggok as Master Lee arrives.
Uk finds Bu-yeon at Jeongjingak, explains the ice stone, and admits that when the lantern goes dark he longs for her; she turns it off.
Bu-yeon feels the ice stone's power inside him; Uk admits he no longer wants it gone, and she vows never to grant that wish.
Planning to undo the promise, Uk practises his marriage plea; Bu-yeon lets slip her mother's needles and decides to go home first.
Bu-yeon fusses over Uk before leaving and says she knew he was her husband at first sight, echoing an old memory, while someone watches.
Yul tells of a dream of losing someone he cherished, says she will learn who she really is, and asks her to turn a blind eye.
Watching Uk change, Bu-yeon asks about the sword scar, refuses to visit Danhyanggok, and is moved that he asks her to wait.
At Uk's graveyard Yun-ok splashes a scar-revealing medicine on Bu-yeon; Yul stops her, and Bu-yeon sees the blue marks and asks if she is her.
At the tree, memories of her crazy master flood back and she realises she was Naksu, then the body's true owner speaks to her.
Bu-yeon says she remembers a man she hurt too badly to face; Uk, wounded and jealous, lets her go as she leaves for Jinyowon.
Uk sneaks into her old room, refuses her 'confused' excuse, and vows to be the brazier waiting until she misses him.
When Lady Jin sends for the plaque, Bu-yeon pulls rank on Cho-yeon to go herself, remembering Jin Mu as the man who trained and killed her.
Bu-yeon arrives with the plaque, refuses to surrender it, and offers to prove her returning divine powers to Jin Mu.
Jin Mu throws the plaque into the sorcerers' prison Gwido; despite Ho-gyeong's fear of the wraiths, Bu-yeon promises to bring it back.
Bu-yeon is daunted by the vast prison; after a long silence Uk appears beside her and asks about the marks in her eyes.
Cornered in Gwido, Bu-yeon admits she is a soul shifter whose soul belongs to someone else; Uk hides it and claims the right to stand that close.
The missing turtle turns up and a door to Gwido appears; Bu-yeon later admits she opened it herself and regrets what Uk saw.
Searching for the plaque, Go Won asks for the blue jade back, then admits he wanted Naksu and is ashamed; Bu-yeon tells him to hurt, then let go.
Alone with her, Uk explains why he must not recognize her, wonders aloud about staying together, and answers that it would be wrong despite the longing.
In Gwido, Jin Mu thinks Bu-yeon will help him claim an ice stone, but it drains him instead, and he realises who she really is.
Bu-yeon resolves to stay in Gwido until her soul vanishes so Uk need not slay her; the turtle then brings her the Jinyowon Plaque.
Seo Yul reveals Jin Mu controlled soul shifters, so the massacre was not her will; she refuses to accept it as an excuse.
