Episode 51 - Reunion "Saikai" (再会)

As Team Kakashi continues their search for Sasuke, Sai approaches Sasuke's room and awakens him. Shaken by the image of Sasuke's Sharingan from earlier, Sai attempts to restrain him. A large explosion occurs and Sakura, Naruto and Yamato catch up. At first Sakura tries to restrain Sai in order to find out his true objective, but she stops, stunned at seeing her former comrade. Contrary to what the rest of the team assumed to be his mission, Sai tells them that he wishes to bring Sasuke back to Konoha.
