Started to think about it, why didn't Jiraiya take Nagato to the Leaf, cause of his Rinnegan? I know that it's something that Danzo would do, to make the Leaf stronger, but why didn't Jiraiya take those 3 to the Leaf village? Then they would have Sharingan, Byakugan and even Rinnegan. Plus, 3 pretty decent shinobi.
