Leitha is a Lady of the Land in Tear.
She is horse-faced.
Like most Tairens, Lady Leitha dislikes Aes Sedai. In the Heart of the Stone of Tear, she draws her skirts away from Moiraine's presence a little too assiduously as the Aes Sedai walks by. So Moiraine stares her down causing her to shudder and drop her eyes. Moiraine thinks to herself that she will not endure open rudeness as well as veiled slights.
