These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: Jigoro is still a Jerk Ass who strongly dislikes Hisao, but Shizune suggests here that his attempts to get her to talk were out of a desire to enable her to succeed as an adult, and she appreciated not being treated any differently from her brother. She is, however, annoyed that he would take it personally when she refuses to speak due to how awkward she sounds.
Better Than Canon: One case of making Shizune's route's subtle emotional aspect more obvious.
