User blog comment:GinIchimaru/The Zero Squad: Reality vs Speculation?/@comment-452405-20100414062220

I just had a random thought, if the Zero Squad does come into play maybe those slim views into their working may have been purposely dropped to be a situation where the Zero's appear and everyone will be, "It all makes sense now!"

We've had Hikifune promoted and Ginrei mentioned but his whereabouts not explained. Rukia mentions really early that they are supposed to deal with things like Menos appearing in the real world (though this might've been just something to say as to suggest the hollow's supposed power compared to regular shinigami). I wonder if they were the only hints dropped if there has been others.....
