Theory: Kakashi has EMS
People are saying that the only way to have EMS, someone needs to take his brothers eye, but was it stated that it was the only way to achieve it? I don't think. Where does this behaviour come from? It comes from Itachi's statement against Sasuke, or especially from MadaraThere were no EMS user before Madara. No one knew how to achieve EMS. Even Madara himself was only desperate because of the lost of his light by overusing his MS, and it's why he took his brothers eye, and discovered later that he had a new and inextinguishable light
But the fact that Madara discovered that by this method, you can achieve EMS doesn't mean it's the only method. Many Uchihas tried over years to achieve EMS by taking eyes from other Uchihas, which means that the secret to achieve EMS wasn't known until Madara and even later, they had to try and try to discover that it only works within clansmen
So now, i would like to ask you "what if taking his brothers eye is not the only way to achieve EMS?"
After all, nothing proves it is. Then yet came an idea into my mind. Itachi talks about taking your brothers eye to achieve a new light
Remember that Kakashi died against Pain
What if Kakashi's death was planned by Kishimoto? I know it seems probably weird for you, but what if it was the case.
If it's like i think, it's possible that when Kakashi got revived by Nagato, by regaining another life, he gained another light
So if it's really how it is, don't you think it's possible that from that moment, he got EMS?
