So, as of now, I'm pretty sure everyone has understood how Nagato got the Rinnengan. And, ultimatelly, how it did awaken. Now, the only question that remains is this: Why did Madara choose Nagato, simingly a random orphan with Uzumaki (thus Senju) blood, instead of any other Uzumaki or Senju that was living in Konoha, a place close to him. Madara obviously had kinetic problems, so why would he travel all the way to Nagato's country? I'm hearing your thoughts...
