Nope, no one is in H2O: Just Add Water's 4th season because they never made a Season 4.
On iPlayer. Go into a search box and type iPlayer Nickelodeon and it will come up. Hope this helped.
H2O: Just Add Water can legally be watched via Hulu and DailyMotion.
season 4 has not yet been released, so you can't watch it online, but it should be shown on tv later 2011, or begining 2012
no there is a season 5
Never, because there will not be a fourth season of H2O.
you can either download it off kickass torrents or watch it on youtube
