There's no reaction to Gwenaëlle faltering, but unfortunately, that tells them nothing about whether or not he noticed it. He is a man who has lived to be old and powerful among Orlais' nobility; not reacting is table stakes. He, unlike Strange, does not look in the direction she'd been looking.

Romain lets her answer the doctor's question as she likes. His comment is more of an aside, responding to what Gwenaëlle had said first: "I think you are taken seriously, at least in some quarters, for what it's worth. But you know perfectly well that it's not only what you do for the world at large. It's what you might do for the people considering you. A few in the Game have noticed that the world is at war, but even so... old habits." That observation might have the smallest hint of judgment to it, but only in contrast to how neutral his observations have been previously.
