Ok, here I go again.
The narrator/MOH/Prince William's true love/whatever left out the part at the end where, right after he "swept her up in a circle and planted," he looked deeply into her eyes and began mouthing the words to "I've Had The Time Of My Life" and then everyone on the ship, from the guests to the crew to the captain to the waiters to the room stewards, broke into simultaneous, professionally choreographed song and dance. Then he jumped off the stage and ran down to the other end of the room, and everyone gently lifted her off the stage and set her on the floor, setting her up to run to him and jump up, while he lifts her over his head, with her arms straight out to the sides and toes pointed, thereby perfectly completing the dance lift they had been working on for weeks but she had been afraid to try.
Oh, why not. It's as likely as the rest of her story.
