When Sharon and Mike return home, the kids ask Sharon and Mike if they would marry each other, Mike proposes and Sharon accepts and they tell them they arranged the wedding for that Saturday. Sharon decides for Lauren that Tony can come to the wedding and make a speech, which Tony agrees to do and Fran and Jake are disappointed they won't be able to go due to being at a festival with Andy.
