I'm not sure if there are any articles on this already, but I find myself looking for inconsistencies within the Bleach-verse more and more. And I believe that I have found one that is infallibly inconsistent! Unless the translation is off...

It just mentions that Urahara was exiled for the gigai, rather than for hollowification. A small hiccup in the story, but a hiccup nonetheless. What other inconsistencies have you found?
