she left because:
in the show she is supposed to be traveling the world with her parents
in her real life she was actually filming the messengers 2 when they were filming season 3
Emma and her family moved away to another place and she is later replaced by Bella
No in season 3 Emma moves. Clarie Holt who plays Emma in H20 Just Add Water is working on a movie now in 2012. If they make a season 4 Emma/Clarie Holt might come back.
Emma Gilbert, a character from the TV show "H2O: Just Add Water," is portrayed as a teenager, so she is generally assumed to be around 16-17 years old.
Bella has replaced Emma in season 3 because the actor playing Emma Gilbert, Claire Holt, is busy filming for the movie Messenger 2:The Scarecrow. However, there are rumors going around that Emma will be back in season 4.
Yeah there's gonna be a season 4 and also Emma is gonna come back on season 4, Emma wasn't in season three because she was shooting a movie and so now when Emma is back on season 4 there's gonna be four mermaids because Bella is in h20 now too
Emma left h20 because she had to go to Hollywood to shoot another movie but Emma returns to h20 in season 4
Claire Holt is Emma Gilbert in h20 just add water.
Emma's little brother on H2O is Elliot Gilbert.
Emma and her family moved away to another place and she is later replaced by Bella
there is only one new mermaid in h20 so far - Bella who replaces Emma
It is at the juicenet
In my opinion i believe that both bella and emma should be liked equally.
Rikki is Caribia Heine Emma is
Claire Holt
Clarie Holt
Claire Holt plays Emma in h20 and why in the world did you need to know that. your sad Ignore that. But do pay attention to the opening credits, Clair Holt plays her. When it first started i thought they were in England.
That Cleo,Emma and Rikki never told the secret.
