The range of emotion Kyouko showed (and acted) in the episode was excellent, derranged, killing intent, fear of death (especially), etc. It's not like you get that everyday
As for uncensoring her in BD/DVD, I beg to differ, just go watch/read any hentai, quality guro is far rarer these days, so I would like to see her getting the Arc treatment from Tsukihime's opening, as drawn in the manga ... though her lower half crawling to the upper (even covered by her cloak) was a nice treat
