You know I would be laughing my head OFF when tobi is revealed and he is not shisui. That would make my day and I wonder what would KYF respond to that be when that happens. He will have no choice to admit he was wrong but still covering himself on some points and blame kishi for it (just like his theory of izanami being opposite izanagi; I liked the idea but it was wrong).
However, if surprisingly tobi turns out to be shisui, there is no question that KYF IS KISHI,who is just trolling in this forum
. I mean it has to be, that is the only rational explanation I can think of from my little brain
