Comments of chapter undefined of Fate in Bleach: Unlimited Blade Works!

A soul reaper can possess and leave a gigai at will, he watched bleach and should know that Urahara lied to him. Doesn't he notice that? Or is he genuinely clueless? IDK about the mc's IQ, but his character so far makes it hard for me to believe he doesn't understand anything, does he have some sort of plan? If not, he really shouldn't be led around the nose by others, even if he like Urahara and Yoroichi from canon.

why didn't he make a sword to heal his wife though ?

Thanks for the chapter
