I was supper sad when I found out my favorite mermaid wasnt going to be in the third season. Any Emma fan, any H2o just add water fan was. I don't know if Indiana Evans will play a good mermaid. But it is very likely because she was a wounderful Matilda Hunter on Home and Away.
Emma and her family are moving away from Cleo, Rikki, and Mako Island.
Bella has been a mermaid sence she was 8 years old, and is said to bring new energy to the group.
Rikki and Zane break-up.
Also there will be a new guy named Will. I don't know, but I think Bella, Rikki, and Charlotte will like Will.
