It also seems to you that Mary shouldn't be Robert's girl. It's just not a good match, so it is likely that he became engaged to her before he ever met the rest of her family. It is Lisa that would be the perfect match for him, as he would be the perfect match for her. They both have obviously realized this, but they each have such a stubborn sense of honor that they could never act upon it. Both felt honor bound to go through with this wedding. At this point, however, Robert sees the bridesmaids and also instantly realizes what happened at the Bachelorette party. He is as furious and disgusted as Lisa is. Both control their anger, however. Robert just calmly says, The wedding's off. Permanently. kissSo now Robert and Lisa fall into each other's arms. When you realize that they have kept their feelings for each other buried, even from each other, throughout the many months of the engagement, you see that this is no violation of their sense of honor. They both know, without words, that now they can and will be married, just as soon as they can get a license. They begin passionately kissing. Mary just sits there, quietly crushed and oblivious, but she knows that she brought this upon herself. On the other hand, the bridesmaids (who have now seen but not recognized you), in an effort to erase their shame for last night, start egging on Robert and Lisa! They can't be as blatant as last night, but they'll push it as far as they can."
