I'm not annoyed or salty on the matter, I would just like a good explanation for Yachiru wandering around an entirely different district before Zaraki showed up and saved her.

That is, if she is his Zanpakuto Spirit, its a very odd thing to do. Especially since he talked to his Spirit to release Shikai.

When she first said "use my power" and the "Bankai" I immediately reflected back to the "Tensa Zangetsu" rather than old man Zangetsu and how they were somewhat different beings in some way.
