Alright this isn't the normal plot hole discovering stating that Nagato cannot revive Madara or whatnot but this is the real problem. Tobi = Madara in Konan and Nagato's eyes. Knowing this, if Tobi asked Nagato to revive Madara, Nagato would be like, how would I revive someone already dead? It wouldn't make sense. Nagato might get enraged knowing that Tobi isn't Madara... Possibly kill him with Konan's help
Or maybe Nagato was meaning to betray 'Madara' all along.
Anyways; Plot Hole is Nagato thought that Tobi is Madara so why would he revive someone he thinks is alive...?
