This will be a relatively short thread because there isn't a large amount to discuss but i've noticed something strange about Madara knowing the seal to independently release Edo Tensei.
Everyone claims that because Madara and Tobirama lived around the same time, he undoubtley saw Tobirama perform the technique and etc and eventually he figured out how to release it, in case he ever needed it.
However in the Tobirama and Hashi vs Hiruzen fight where, Tobirama was brought back as a Edo, he himself, the creator of the Jutsu who was the only person who Madara could of learned the technique from didn't release the Jutsu so he could side with Hiruzen and yet that the same time Madara, someone seemingly unrelated to the Jutsu knew how to.
If anyone has the answer to this, a explanation would be good as my memory from that Hiruzen fight is a bit fuzzy.
