i think we're all missing the point here
isn't the original question just what happened 2 the badge that expanded out as a cape that yoruichi gave him that allowed him 2 fly? not the medallion thing that ukitate gave him (it just allowed ichigo 2 transform in2 shinigami by himself didn't it?)
u know, just when the sokyoku was about 2 kill rukia?
anyway i dun remember but didn't he just throw it away somewhere just b4 he fought byakuya ?
