Gosh, I genuinely felt so bad for Yamato trying to wrangle Naruto and Sai in this episode; those two were constantly at each other's throats about Sasuke, which honestly just highlighted how desperately the team needed Kakashi's calming presence. It's like Sai *knows* how to push Naruto's buttons, even if he doesn't fully get why it hurts, but at least that simulation finally forced them to confront how dysfunctional they'd become.
