- We see the Ame orphans fine and dandy when Obito approached them. Funny, considering both Kannabi Bridge Battle and Akatsuki vs Hanzou and Danzou were closing acts of the Third Shinobi World War. It seems Yahiko is a Schroedinger's Cat wannabe.
Number 1 is not a plot hole, Madara in this chapter said he awakened the eye shortly before he was soon to die. He used the eye to unseal gedo mazo, which he used to to create the hashi flower, now instead of dying, the mazo's power kept him alive from when he gave away his eyes till he met obito.
Basically, a laptop that has its battery pulled out will stay on till disconected from the charger.
Madara "dead" but was now connected to the mazo.
Number 2 not a plot hole, read the chapter again, all he said was he is from the lineage of senju, which could mean though both clans existed at the same period, Uzumaki descended from Senju at sometime in historyand some certain Senju descendants were unique enough to be a clan of their own.
