Synopsis
Baki tells Kankurō and Temari that they are suppose to watch over their brother Gaara. Kankurō and Temari go to Gaara's room and are surprised to find him missing. Naruto has slept for three days, meaning the Chūnin Exams finals will start the next day. Shikamaru gives Naruto a fruit basket originally intended for Chōji. Sakura goes to Lee's room and replaces the flower. Chōji complains of his hunger, and Ino walks in with a fruit basket for him. Gaara enters Lee's room and attempts to kill Lee while he is unconscious, but Naruto and Shikamaru immediately stop him. Gaara tells them of his past and the monster inside him. Naruto sympathasises, saying he also has a monster inside him. Gaara attempts to kill the two of them, but Guy steps in and demands Gaara to leave at once. Gaara has no choice but to do so, but before doing it, he promises that he'll kill them all.
