this is my first post so ima make it good..
When i was watching the Sasuke vs itachi fight i noticed something funny about the way Itachi was talking. At the time you think nothing of it because its before the whole "who is tobi" fiasco. (I knew He was Obito the WHOLE time) but if you remember He keeps talking about his teacher madara then he starts referring to madara as old, a shell of his former self, and how hes no longer a threat. we all understand that itachi manipulates sasuke but i see no reason for him to lie to him about Madara if he ultimately wanted him to survive. and right after itachi dies obito starts saying hes madara
when the Manga flips back to Obito and Madara. the Old Madara is exactly how Itachi described him. it shows how he is barely alive let alone able to fight. Itachi has no loyalty to the akatski and as we all know he smart as all hell, so i would see no reason he would not know everything about the group he's secretly spying on. i understand that tobi admitted to being the person that helped itachi but we have not seen 1 flash back with tobi at the uchiha masacre. and Itachi was dead before Tobi mentioned he was there..
Nagato. Madara knew who Nagato was when he was brought back. and from what ive seen i know implanted eyes cant transform from the regular eyes they stay powered up (Kakashi, nagato, the bijuus w/tobi etc) (unless theyre uchihas and compatible brothers) and Madara is the only person wit a Rinnegan who could of gave it to him. now how does this relate to Itachi, Obito takes credit for it when madara is the only one who could of done it
Tobi completely took on the persona of Madara so he admitted to everything Madara did including taking his brothers eyes and fighting the 1st.. So how can we credit tobi with any of the things he said before we knew who he was.. and one more thing ima add when the edo tense brought itachi back sasuke started asking him question about the past and saying things he shouldn't of known and Itachi was surprised that tobi knew so much about him. if tobi was there how does tobi knowing so much surprise him. there's a lot more evidence i can list but what do yall think
