Esther's standing being open is not contradictory to the text. She is definitely the fiancee of Barton, who is a knight, and is either lying about being the same or is telling the truth about being the same (i.e., a knight). That's all that the text says.

Of course it's an exclusive or between liar and knight. I never said it wasn't.
