So I know a big thought Ive been having in regards to the war is that it would be cool if suigetsu and zabuza fought but the problem is zabuza has his sword and sui isnt really very strong without it...but you know what I just realized like 2 minutes ago, when zabuzas sword gets blood on it, it repairs...which means suigetsu could have already gone back and gotten that piece of it that got ripped off, then all he would have to do is cut someone with it or even use his own blood and valla the sword is reborn, then their would be two of them and suigetsu would have his own...does this not make sense?
