[[Shikamaru]] points out to [[Tsunade]] that a [[medical-nin]] should have been assigned to the [[Sasuke Retrieval Team]]. She agrees, but says that being a medical-nin requires "something special". Shikamaru goes to visit [[Naruto]] in the hospital and gets confirmation that [[Sasuke]] would not come back to [[Konoha]]. [[Sakura]] overhears this but pretends not to, entering the room to see how Naruto is doing. Naruto apologizes for failing but she avoids the subject. He persists, saying that he will one day fulfil his promise of bringing Sasuke home. Seeing how much Naruto has gone through, Sakura leaves after telling him that he won't need to fulfil that promise by himself next time. Sakura goes to see Tsunade and asks to learn how to become a medical-nin. Seeing that Sakura has that "special something", the desire to avoid losing those one is close to, Tsunade accepts.
