Mr. Crawford’s business had been to declare himself the lover of Fanny, make decided proposals for her, and entreat the sanction of the uncle, who seemed to stand in the place of her parents; and he had done it all so well, so openly, so liberally, so properly, that Sir Thomas, feeling, moreover, his own replies, and his own remarks to have been very much to the purpose, was exceedingly happy to give the particulars of their conversation; and little aware of what was passing in his niece’s mind, conceived that by such details he must be gratifying her far more than himself.

As much as do not wish to defend Henry I feel that I must. (:D) I do not think Henry lied to Sir Thomas or asked him specifically to interfere. He applied to Sir Thomas as Fanny’s guardian for approval rather than to obtain his influence with Fanny—see above. Sir Thomas’ purpose in visiting Fanny in the East Room was to tell her of his approval of the match. He really had no idea of the storm to come. I do not think Henry lied to Sir Thomas because he has no reason. He is too vain to believe she is really unwilling and feels her reluctance is due to modesty and surprise. He feels sure he can eventually win her affection (Ch. 34). Aside from Henry’s terminal optimism (thanks Tom P2) both he and Sir Thomas see Fanny’s reaction to the offer as that of a proper modest young lady—rather than explain my position on Fanny’s demeanor further I will link a previous post on this subject at the end of this message. I do not feel Sir Thomas has a reason to suspect Henry of giving a false picture of the proposal because he was very surprised to find he also misinterpreted Fanny’s demeanor towards Henry. He observed them at the parsonage and at the ball and never suspected Henry attentions were disagreeable to her. Sir Thomas thinks the match is advantageous to Fanny in all of its aspects which he makes plain to her but I think this is prudence and concern for her future rather than worldly vanity. (:D)
