Hashirama is so cool!
I have new hopes because now I know why Kishimoto still hasn't shown Tsunade dying. It's clear enough for me that when Hashirama finds out what Madara did to Tsunade he will break through Edo Tensei just as Madara did, and he's going to meet Tsunade and have a talk with her and maybe heal her or at least go tell her he's proud of her and that he approves of hers then let her go and close her eyes. I picture him crying and showing up in front of Madara still full of rage and going full power with his Wood Dragon against the Juubi and then target Madara, getting him off the Juubi and telling him something like "I will finish what I started, your hatred has gone way too far".
Can't wait!!!!
