Mr. Knightley confronts Emma about Harriet

Mr. Knightley calls at Hartfield and informs Emma that Robert Martin has consulted him about proposing to Harriet. He is shocked and angry when Emma reveals that Harriet has already refused him. He correctly accuses Emma of persuading Harriet to do so, arguing that Robert Martin is a far better match for her than she deserves. Emma defends her actions, insisting on Harriet's superior social claims. The argument is heated, and Mr. Knightley warns Emma that her matchmaking with Mr. Elton will also fail, as Elton is too prudent to marry a woman of obscure birth. He leaves in a state of vexation.
