Killer Bee and Motoi

Motoi confesses to Naruto and Yamato that he attempted to kill Bee during their childhood because of his father's death due to the sealing of the Eight Tails 30 years ago. As the young Bee became the Jinchuriki of Eight-Tails, Motoi realized that Bee had the same maltreatment of people just like Naruto and he understood what kind of life Bee is experiencing that time. After Motoi's confession, Naruto leaves the Waterfalls of Truth and heads to edge of the island where he thinks how to overcome his hatred and defeat his dark self. The squid again returns and attacks Naruto but Motoi is caught from its tentacles, then Bee appeared as the Eight Tails defeating the squid and saving Motoi. Motoi asked Bee why saved him despite he attempted to kill Bee. Bee answered in a rap that he and Motoi will remain good friends.
