Hi emmaandcleo i love h2o too. I heard that there will be a season 4 in the year of 2016. I heard that they were returning to the set but they don't know if all the casts are returning, they might get new actors to fill in for them or something. In season 1-2, i don't really have a fav character although however i do like emma. In season 3 i like Bella. She is a pretty good sing and i kinda like her as my fav charcaters but i like all the characters as well.over a year ago
