But an interesting fact is, Hakkai treated Goku just like how Tenpou treated him. Gojyo and Kenren treated Goku as their little brother. Sanzo ... welll... I don't know but an interesting fact, there is someone calling him in his heart and that was Goku.

I still consider them the same person at the heart and soul only. Get it? XD
