"I think you might be a bit of a romantic, Monsieur Lebeau," It's not a question, when she's sure that's the impression he wants to give. (Whether it's true or not will take a little more effort to figure out, on her part). The accent, the French words peppered through his speech, certainly help with the getting that image across. It's also not really an agreement or disagreement with the statement.

There's another comment on her tongue, about working for ladies, but she decides against it, swallowing that particular bitterness down.
