Kakashi Hatake, The Jonin in Charge

Watching Naruto and Sakura Haruno help out in the effort to rebuild their home, Kakashi has a flashback of when Hiruzen briefed him that he would be assigned them and Sasuke, accompanying him to Naruto's apartment where they find the long-expired milk which the boy drank before meeting up with his classmates on their last day of Ninja Academy and team assignments. Kakashi observes Team 7 from the behind the scenes, from Naruto's attempt to get close to Sakura to being outmatched by Sasuke when he attempted to attack him for hurting Sakura's feelings. It then goes back to the present as Kakashi notes that taking down the now rogue ninja Sasuke is his task to bear.
