To disconcert someone is to throw them a little off balance: they feel slightly confused, embarrassed, or worried, often because the moment was not what they had arranged in their head. A long look, a blunt question, a silence, or a small plan that fails can disconcert a person. It is more than a tiny surprise and less than a shock.
