Naruto Shippūden - Season 5 Episode 100 Inside the Mist

Guren is rendered unconscious and relives her past as Naruto is caught in an illusion about Sasuke. After Kakashi finds him, Teams Kakashi and Kurenai conclude the mist around them causes Genjutsu courtesy of the Three-Tails. After Guren wakes up, Yūkimaru suffers another fever and passes out. Tsunade hears of the Three-Tails and assmbles Shizune, Ino, Tenten and Lee to go and seal it before the Akatsuki do. Naruto and Sakura talk about the home that people should return to before Naruto heads off to find Yūkimaru.
