"Naruto and Sasuke and Sakura" (ナルトとサスケとサクラ, Naruto to Sasuke to Sakura) is chapter 286 of the original Naruto manga.
Naruto has difficulty getting along with Sai, finding him unpleasant and otherwise inferior to Sasuke. Sai has no issues with not living up to Sasuke's precedent, thinking of him as nothing more than a traitor who went to Orochimaru for the shallow reason of gaining power. Naruto tries to attack him for insulting Sasuke but Sakura stops him. She attacks Sai instead. Yamato breaks up the fight and forces them to get along. To improve teamwork they spend the night at a spa, where Sai once again finds the opportunity to question Naruto's masculinity.
