As Mary swam contently in her pool as a dolphin, her boyfriend arrived to visit. When she didn't answer the doorbell or the phone, John let himself in with the spare key Mary had given him. He looked through the house. Nobody was home, but he did come across Mary's purse and keys so it seemed very odd she wasn't there. Then he heard a splash in the pool.
John went outside and was surprised to find a dolphin swimming in Mary's pool. He wondered how that could've gotten here, especially with Mary not around. The dolphin seemed quite content to be there. John took a seat on one of the pool chairs, watching the dolphin swim and wondering where Mary could be. He did notice a pile of clothes on the pool deck next to the chair, along with a box.
As John tried to figure out what was going on, Mary the dolphin made a leap in her pool and noticed John's prescense. She wondered if there was any way to get his attention? She guessed there was at least another half hour until the pool's cleaning system flushed the human vial's contents into the pool and changed her back.
