Another aspect of Petruchio's nature that adds to his appeal is the way in which he grows to trust his wife — something none of the other characters do. The play's final scene provides the best example when, in the midst of the banquet, Petruchio eagerly puts his reputation in Kate's hands. For him, the initial twenty crown wager is an insult, causing him to exclaim "I'll venture so much of my hawk or hound, / But twenty times so much upon my wife" (V.2, 73–74). Kate comes when she is called, as Petruchio was sure she would, but in giving Kate the task of telling "these headstrong women / What duty they do owe their lords and husbands" (V.2, 144–145), he releases complete control of his reputation. At this point, whatever she says will reflect not only on her, but on him as well. At this point Petruchio is also giving Kate an unparalleled opportunity: to address and instruct the party. Clearly he trusts her — so much, in fact, that he is willing to share the public forum with her (an extraordinary occurrence for a woman). Kate's formidable speech leaves her own husband speechless, able to exclaim only "Why, there's a wench!" (184).
Although in many ways Petruchio is like his wife, admittedly he doesn't undergo the same sort of maturation and development as she does (after all, his tyranny is clearly a fiction, a parody created to help Kate see the senselessness of her behavior). It would be unfair, though, to claim he remains static. When we look back to the Petruchio of the early acts, he is determined to live solely for himself, intending to exist largely on the dowry of the wife he hopes to find. If this were his sole motivation, though, what point would there be in his taking the time to help his wife into a partnership? If money were his only goal, surely he wouldn't bother trying to help Kate to a different perspective. When it comes to it, it seems Petruchio does not, in fact, want merely to wive it wealthily. He wants someone who can spar wits with him, challenge him, and excite him intellectually, emotionally, and physically. By the wedding scene, Petruchio has come to this realization; hence, he willingly assumes the all-important role as the catalyst for Kate's change. For instance, purposely arriving late, wearing conspicuously inappropriate attire, and behaving in a completely improper manner at the wedding mark Petruchio's initial steps in getting a wife worth more than merely her money. By play's end his gamble to try and bring Kate to a higher level of understanding pays off. Petruchio gets the mate he desires — but he, too, is changed. He is no longer the mercenary man from the early acts; rather he is a man deserving of the extraordinary partner he has gained.
