2x33 - Naruto Shippūden

Teams Kakashi and Guy return home to Konoha. As Kakashi rests in the infirmary, Sakura tells Tsunade about the information Sasori gave her as a reward for defeating him. Sasori had a meeting scheduled with a spy from within Orochimaru's ranks in 10 days. 4 days have passed since Sakura received this information, and now Naruto and Sakura need to recruit a new team member to go and investigate. As Naruto searches Konoha for a willing recruit, he meets some of his old friends. Just as Choji agrees to help, Shikamaru, Choji, and Naruto are attacked by a Konoha shinobi unknown to them, Sai.
