He's wife must also atleast fit in somewhere in the timeline. This was problaby like centurys ago (remark me if I am wrong here) and if she met her in the real would then...
...then she would be VERY old. A very old lady.
So, my guesses are that...she was low class, as been mention before? You know, forbidden love, maybe just some wierd coincidence Kisuke just did and they all ran off from Soul Society?
