I didn't think Mrs. Fitz was scared or threatening. I think that she was initially shocked to see Claire, a stranger, in her "shift", dismount with Jamie but I don't think she acted at all sinisterly towards Claire. I think she came across as true to the books - efficient and caring and sensible and practical in the extreme.
I have a dumb question. Claire has given her maiden name, Beauchamp, to avoid the complications that would inevitably ensue should she use her true name, Randall. So one would assume that Beauchamp is her married - her husband's - name, since she is identifying as a widow. But in her conversation with Colum, it sounded to me like he was assuming her own family was the family with whom she planned to reunite in France. And he was suspicious that she hadn't met them or ever been there, etc. Did I miss something - do they all assume or did she say that she herself is of French ancestry?
