Chapter 19 - Outstretched Hand -
(AO3 Link)A package arrives for Sakura from Karin containing copies of Orochimaru's lab reports, which is the most that Karin can do to help for the time being while she searches for more leads. Sakura goes through the reports and is immensely disturbed but unable to make much headway. She decides to consult Sasuke and see if he can add any insight from his days in Sound. She stops by his house and finds Ino instead, looking exhausted and unhappy, though she denies anything's wrong when Sakura asks and tells her where Sasuke is. Sakura finds Sasuke training with Go'on, and gets Sasuke to look at the reports, but has no further theories to contribute. Sakura leaves, disappointed and confused by Sasuke's suddenly impatient mood.
Chapter 20 - Bitten Tongue -
(AO3 Link)Sasuke sends Go'on home when he is unable to concentrate, shaken by the records Sakura showed him. Sasuke begins to believe that Yakata is a clone that Orochimaru made of his brother, but feels he is just being delusional again, considering how his other theories were proven wrong. Sasuke resolves to visit Karin and talk to her himself, to see if his final theory is plausible or not. Their meeting is full of awkward conversation, where Karin asks about Sasuke's family and talks about the child she herself is expecting, even though she is now in her 40's. When they get down to business, Karin has no new theories to add. Sasuke is about to lose his temper when a young man enters that looks exactly like Orochimaru. Karin introduces him as her son, Ooda, and leaves with Sasuke to talk privately in her living room.
Chapter 21 - Frozen Teeth -
(AO3 Link)Karin explains that Ooda was left at her clinic as an infant with a note from Orochimaru asking for her to care for him until his return. He is an exact genetic duplicate of Orochimaru, though he has not been informed of this, for the sake of his mental health. Karin has held off on telling other people about him for fear of harm coming to her or to Ooda, or to cause unnecessary trouble, if Orochimaru is no longer active, especially since so many years have passed without any further contact from him. Sasuke then tells Karin about Yakata, and from this new information she comes up with a theory that Yakata and Kiine are both clones made by Orochimaru. Sasuke makes a plan to go see Yakata again and gather more information for Karin and Sakura. Karin makes him promise not to tell anyone else about Ooda, however, and Sasuke agrees.
Chapter 22 - White Wing -
(AO3 Link)Sasuke returns to Tamina to speak with the Honbo family, compiling the questions he wants to ask them along the way. However, Yakata answers the door with anger, and his parents are angry as well. Sasuke learns that, during his previous visit to Tamina, Yakata became convinced that Sasuke was his biological father--he was given to the Honbo family as an infant by a hooded man. Forced into a corner when asked why he has returned, Sasuke makes up a story about Itachi being Yakata's father, and that he returned when he found letters of Itachi's that mentioned leaving a child behind. Yakata's parents do not question the story, and are likewise cooperative when Sasuke asks them if he can bring Yakata back to Konoha with him for blood tests and ninja training. They all decide to sleep on it.
Chapter 23 - Pupil Reflection -
(AO3 Link)Yakata thinks about what Sasuke has said, and decides that he wants to go with him for not just the blood tests, but the training as well. Having had a childhood full of punishments for his unnatural intellect and skills, resulting in the nickname of "witch-boy," extreme shyness, and a stutter, Yakata wishes to learn a "trade" that will allow him to prove useful for once. He packs his things in the morning after Sasuke arrives, and the two depart for Konoha.
Chapter 24 - Ankle Memory -
(AO3 Link)Sasuke and Yakata journey from Tamina to Konoha, talking of many things on the way. Yakata asks about Sasuke's family, as well as Itachi. Sasuke pokes Yakata on the forehead while they have lunch, much like Itachi used to do to him, as the subject comes up during the meal. They camp out for the night, and Yakata is dazzled by Sasuke's fireball technique, though he grows self-conscious when Sasuke brings up his stutter. Sasuke tells Yakata not to mind if people stare at him in Konoha, which Yakata worries over. They end up humming songs to each other on the final leg of the journey to avoid talking.
Chapter 25 - Blurred Vision -
(AO3 Link)Sasuke brings Yakata to his house and introduces him to Ino without much explanation, and tells her to get dinner started while he shows Yakata around. He then takes Yakata to the ruins of the old Uchiha compound. When Sasuke takes Yakata to the plot of land where his old home used to stand, Yakata finds himself unable to breathe and grows frightened. Sasuke takes him to the lake to calm down, but the pair are interrupted by Murasaki. Sasuke leaves in anger and warns Yakata to never listen to her. Sasuke also orders Yakata to not bring Itachi up around his family. They run into Nadeshiko on the way back inside, though she retreats at the sight of Sasuke, and Sasuke tenses up when Yakata asks about her. Yakata goes to take a bath and is cheered up when he finds that someone has left out clean clothes for him.
Chapter 26 - Stretched Tendons -
(AO3 Link)Yakata is introduced to the members of Sasuke's family, one by one, and helps Karai set the table. Sasuke explains that Yakata is a boy he has taken in to train, and completely leaves out any mention of Yakata's identity or "parentage." A mild scuffle breaks out when Sasuke says he wants for Inou to share his room with Yakata, until Hajime, the oldest son, volunteers to stay at a friend's house while Yakata uses his room. Karai helps him move in, and Nadeshiko offers to help as well, though she leaves. Yakata asks Karai why Sasuke seems to have an issue with her, and Karai responds that it's always been that way. Yakata goes to bed early, after Sasuke reminds him how busy the next day will be.
Chapter 27 - Severed Nerve -
(AO3 Link)Sasuke and Ino have a severe argument in which Ino demands to know who Yakata really is, and Sasuke tells her. She grows enraged when she learns that Sasuke has lied to the boy and told him that Itachi was his father, and that Sasuke expects for him never to ask anyone else about Itachi. Much of her energy is spent in trying to keep him quiet, so nobody else hears. Ino eventually dares to insult Sasuke as badly as he insults her, and ends up with an injured arm from Sasuke squeezing it so tightly. The argument only ends when the second son, Takeru, comes down for a glass of water, forcing the two to drop the issue.
Chapter 28 - Familiar Blood -
(AO3 Link)Sasuke takes Yakata to the hospital and introduces him to Sakura so she can draw blood from him for testing. Sasuke gets her up to speed about the things that he and Karin discussed, as well, but keeps his promise in not telling her about Ooda. They both decide to only tell Naruto if the tests on Yakata come back positive, which they do: he has the same chakra-saturated cells that Kiine does. Sakura then visits Naruto and finds him working on how to handle the debts left to them by the Taki clan. Surprisingly, Naruto seems to have forgotten the fact that Kiine is an Uzumaki in the time since Sakura first came to him about it. Naruto asks Sakura if she thinks Sasuke has been acting strangely, before she leaves, and from that she figures that Sasuke hasn't told Naruto about Yakata's identity and decides not to say anything either.
Chapter 29 - Paper Cut -
(AO3 Link)Sakura sends in Yakata's blood for further testing, and checks in with Ino about how she's handling having him in the house. The training is already taking its toll on Yakata's body, but Ino does not tell Sakura this. Sasuke spends some time in telling Yakata about his past, and gives him a photograph of Itachi and his family from when Sasuke was a child. Nadeshiko also leaves small gifts in the form of flowers and books on the desk in Yakata's room, though she avoids talking to him overtly. Karin writes to Sasuke, appalled at his decision to bring Yakata to Konoha, and rebukes him for referring to Yakata as Itachi in one of his letters. Meanwhile, Naruto writes a letter to the Taki clan.
