Ah, thanks for clearing that up [img]i/expressions/face-icon-small-tongue.gif[/img] I made that post rather late at night, I guess his point didn't quite get across to me.
But even then, he's wrong. The branch family doesn't "protect" the head family by acting like a bodyguard for a talentless head family member. The branch does protect the head family, but a head family member would never be expected to just sit there and not fight. The branch family is used to ensure the progression of the clan's "nobility". That's why they have the seal placed on them. At least that's how I understand it.
And Neji's Kaiten pwns all.
