Jim is suddenly very acutely painfully aware that Isidor only knows Captain Kirk. But for a few breaks in his facade, he's never been in a position to be himself around the Durant mage. And honestly if she hadn't come to him for advice in the first place he would only know Isidor Durant as the take charge no nonsense fun is a four letter word hard-ass she presents herself as.
