In predict that in the future Wendy will start to fit in but will still miss her family. I think she will also reunite with her brother. She will probably have difficulty getting use to being a princess because she wasn't a princess before. Right now Wendy and her real mom don't have a very good relationship but I think the more Wendy lives with her in the same house they will start to get closer and will have a good relationship in the end.
I wonder if Wendy will ever get to go back to her old house. She is living in her new home right now but I think she will probably start missing home and go back. If she does go back she will have to sneak out somehow. I also wonder if she will ever find out why she was switched at birth. Since she just got back to Trylle nobody is telling her why she was switched or who she really is. Everything is all a mystery to Wendy right now.
