Austen Said:

recommend Sir Thomas's coming to London himself, and using his influence with his daughter to put an end to the intimacy which was already exposing her to unpleasant remarks, and evidently making Mr. Rushworth uneasy.

the almost desperate situation in which affairs then stood with the young people. Mrs. Rushworth had left her husband's house: Mr. Rushworth had been in great anger and distress to him (Mr. Harding) for his advice;

feared there had been at least very flagrant indiscretion. The maidservant of Mrs. Rushworth, senior, threatened alarmingly. He was doing all in his power to quiet everything, with the hope of Mrs. Rushworth's return, but was so much counteracted in Wimpole Street by the influence of Mr. Rushworth's mother, that the worst consequences might be apprehended.
