Does any of this really matter, when Isshin showed up the Captains and shinigami were all on the ground injured. There was a major battle going on and Isshin left to the Dangai short after. There really was't much time and their reactions really didn't matter story-wise. The only one that should have mattered was Rangiku as she was conscious but she was too conflicted over her childhood friend dying and Isshin was out of it by the time the Dangai training finished. Kubo focused more on the grief and triumph than on "Don't I know you" plots.
