awsome chapter, someone said that maybe Sasori altered his body to make it more puppet like, well I think thats exactly what he did, it was actually cool to see Khan without his crap on(first time we've seen it), and After looking at the title(The Unending hatred) it could mean that Sasuke could be coming, but I doubt it(Ive learned not to trust the preview titles).

and I dont believe that every youma has a human host(would they ALL really be that careless)
