The Spy from Akatsuki!!

Summary
Sakura tries to make Sai appreciate Naruto's attachment to Sasuke by comparing their relationship to the one Sai had with his brother. Sai informs her that his brother is dead, and that when he died he had no emotional response whatsoever. She gives up on trying to make him understand and settles for whatever support he can provide for finding Sasuke. The next day Yamato, disguised as Sasori, meets with Sasori's spy: Kabuto. Yamato asks him about Orochimaru, unaware that Orochimaru is watching.
