Kate ends up seeing the relationship clearly after the scene when the real father comes to see his son. At the end of that scene, Kate looks from a different perspective at her new husband, and finally decides that a) if she wants the relationship to work, she will need to meet him eye to eye, and b) that she cares for him. The second I think can be gathered from the way she acts in public after that scene, and the lightening up of her attitude.
The first point is a little more difficult to prove. I think from this, Kate finally realizes that for her to get what she wants out of life, (from the first few scenes, particularly when she is fighting with her sister, we see that she is quite selfish, jealous, and spoiled) she will have to make some compromises. She realizes after the scene where they finally start to appreciate each other that to do this, she will need to stop being such a Shrew, and do what is best for her husband, in turn doing what is best for herself. During the contest at the end, she knows her husband is up to something, and realizes that it will be to his advantage to go to him. She goes, and delivers that whole speech by the simple fact that she sees her relationship with her husband as a contract. He will try to please her, if she stops being so unpleasable. Thereby, she lowers her expectations, and accepts that she has a husband who cares for her, and that only wishes to make her happy, and in order to do that, she must be willing to help him.
