Caroline Bingley's feelings before. "And the mother!" (or was that an adaptation? I see I need a re-read to refresh my memory!) But as regards NA and JT, when CM is in the carriage/curricle/gig with JT and then understands the Tilneys are there and not gone out without her as JT assured her. My thought was "And the brother!"
Also, does JT intentionally lie to get CM to do as he wishes?
