I did the conclusion.
6 weeks had passed since Ash asked Misty if they should have another child. They agreed on the idea, and went to the hospital the next day when she found out that she was pregnant. However, the doctors were puzzled, because according to their tests, the baby was to come in only 6 weeks. When they returned home, Ash's father explained that it was because Misty was part Vaporeon, so the time period would be the same as if she mated with another Pokemon. Delilah completely changed her lifestyle, and started acting like a normal Vulpix, just like how her husband still prefers to stay a Ninetales.
That night, Ash and Misty returned home with a new child. However, when they walked through the doorway, Misty saw that she was no longer holding her human daughter, but a peacefully sleeping Eevee.
"It looks like she carried on our abilities," said Ash softly, so that he wouldn't wake the child.
"Yes, but what will we name her?"
"How about..." He paused. "Mira."
Okay, thank you to everyone who gave me ideas. I started the next story, but if anyone wants to make a suggestion feel free! It's called Tough Love.
