ok, i am under the impression that Kagami is madara's son. He has been to see to be in the 2nd's team in the ninja war. What if they were both jealous being in there father/brothers shadow? The 2nd may have given kagami his DNA ( explains time-space jutsu) so that kagami could become more powerful then both the 1st and madara....bit crazy but who though madara would get the rinnegan wither? Kishi is a tricky bastard..
