Kabuto's smug mind games were honestly getting on my nerves, so watching Sai actually *physically* restrain him felt incredibly satisfying; it's like he's finally cementing his loyalty, which makes me think he's really turning a new leaf. Naruto's sheer stubbornness to find Sasuke is still just so much a part of him, and honestly, even if those flashbacks slowed the momentum, I'm just glad they're *finally* at the lair, moving towards that reunion.
