Church. Doris drops Mark off. He runs to the door.
Inside, Mark runs toward the nave and slows down when he gets close, buttoning his jacket. His tuxedo? Totally dry. Not at all muddy. Whatever. As soon as the guests see him, everyone starts applauding. Mark smiles sheepishly and stands beside the minister. The wedding march starts. Elizabeth comes down the aisle. People smile at her. No one from Social Services shows up to object that brothers and sisters can't get married in the state of Illinois.
