Naruto Shippuden Episode 36 & 37

Title: "Fake smile" & "Untitled"
Date: November 29, 2007

The new team Kakashi heads out for the Heaven and Earth bridge. Sai, Sakura, and Naruto come to blows after just 5 minutes on the same team due to Sai making fun of Sasuke. Therefore, Yamato decides they need to improve on teamwork and uses Mokuton to create a wooden cage threatening to lock the team up unless they behave. Given an ultimatum between being locked up or spending the night at a hot springs, the team chooses to visit the springs to improve team cohesion. Naruto still despises Sai despite this effort, and several insulting remarks from Sai worsen team relations.

Sakura sees Sai drawing by the river and finds out that Sai has artistic talent but has never given titles to anything he ever drew. Naruto and Sakura begin to realize the reason behind Sai's repulsive personality. After the hot springs, the team heads off to the bridge to meet the spy. Yamato is suspicious of traps so they go off the main road into the forest. Camping for the night, Yamato then creates a two story house by again using his Mokuton jutsu. Inside this house, the team formulates their plan.
