The question is why she's trying to play this one off. (Other than "I'm embarrassed" and "the artist likes Faulty Towers plots".) She has a totally viable out to just say, "Thank God you're here, Kuma! Hold this injured admiral while I throw on some clothes and drag him to the infirmary".

(And why does everyone think this bath is empty? Presumably some sort of indicator, either a "in use" or at least just their change of clothes, should be left behind... unless someone is maliciously stealing their clothes/changing the marker...)
