Something I just noticed when re-reading White Rain for the nth time: one of the themes of the story is how while generations repeat themselves, sometimes they differ in meaningful ways, too. I mean, Sakura's genin team is a dead ringer for the Fourth's: you have the team's ace Amaya (Kakashi), the team's medic Haro (Rin), and the team newbie with a Sharingan Itachi (Obito).
