Nothing

Summary
Kabuto attacks the Uchiha brothers with his Sage Art: Inorganic Reincarnation technique, causing the cave formations to attack them. Having used his Susanoo to protect Sasuke, Itachi is incapacitated between the rocks. As Kabuto retrieves a talisman from his snake, intent on rewriting Itachi's mind, Sasuke creates a ring of Amaterasu flames to prevent Kabuto from taking any further action. Commending Sasuke's strategy, Kabuto tells him nonetheless that they were not capable of defeating him. Continuing to brag about his accomplishments, he states that of anyone currently alive, he had come the closest to the Sage of the Six Paths and that compared to him, the Uchiha were nothing. This prompts Sasuke to lash out at him, but he is stopped by a fully-regenerated Itachi. Itachi tells Kabuto that he reminded him of his former self though the two of them were very different. He then tells him that because he did not understand his own limitations, the value of comrades and who he really was, he was doomed to fail as he did when he was alive. With this, Kabuto retorts that they were the ones that knew nothing about him and that for his whole life, he had tried to find who he really was. Kabuto also has a flashback to his earliest memory of being found by Nonō and Urushi. He then states that for his whole life, he had nothing.
