That question was followed by hesitation. Not on account of wanting to lie but because he needed to actually give that some thought. How long had it been since he started studying the language with help from benefactors? Months? Close to a year? Probably something between those two points. "A few months now. Gotten good enough to hold a conversation and shrug off my own accent and pronounce things properly. For the most part anyway." While honest about that much, he was giving her no indication about his motivations for learning the language. She hadn't elected to ask, so he didn't reward that with an answer. A quirk of his nature she hadn't yet come to understand was that he would almost always answer questions directly. You only needed to be cautious enough to not ask anything you didn't want to know the answer to.
"Will that be all or was there anything else on your mind?" This was a subtle reminder that she could leave whenever she wanted. Otherwise, she was free to initiate any topic of conversation. And at least from his posture and tone, there was no indication that he would be uncomfortable with anything she may decide to talk about.
