Katherine: Husband, let's follow to see the end of this ado.
Petruchio: First kiss me, Kate, and we will.
Katherine: What, in the midst of the street?.
Petruchio: What, art thou ashamed of me?.
Katherine: No, sir, God forbid, but ashamed to kiss.
Petruchio: Why, then, let's home again. (To Grumio) Come sirrah, let's away.
Katherine: Nay, I will give thee a kiss. (She kisses him) Now pray thee, love, stay.
Petruchio: Is not well? Come, my sweet Kate. Better once than never, for never too late.
It seems that Petruchio has finally tamed the shrew through his creative and well put together plan. He uses his own methods of breaking down Katherine by starving her, deriving her of sleep, and treating her badly, then builds her back up again making her an exceptional product of his scheme. It is evident that many characteristics of Katherine's personality have improved such as her conduct and social skills. Katherine's love and emotions toward Petruchio have also deepened despite of his cruel treatment toward her. She respects others but deeply respects Petruchio calling him "sir" (V.i.150), and "love" (V.i.154), rather than calling him a "buzzard" (II.i.219), and a "fool" (II.i.272), as she did when they first met in II.i. She has matured and come to love Petruchio as he has also come to love her in spite of their horrendous wedding and rough beginning. .
Katherine's behavior around others has also changed for the better making her a more tolerable person. This is clearly shown by Katherine's reaction to Petruchio's request to be kissed by her. She responds saying, "What, in the midst of the street?" (V.i.148), resisting to kiss him due to the fact that they are outside in public. Petruchio is expecting such an answer responding, "Art thou ashamed of me?" (V.i.149), Katherine tells him that she is in no way ashamed of him but "ashamed to kiss" (V.i.150). This side of Katherine is very different than what is shown in Acts I and II where yelling and screaming about was commonplace.
