I was rewatching H2O season 1 when I realized something: when u think about, each original character has had their own season that sort of resolved around them. Let's start with the beginning:
Season 1: Emma
u may of may not have noticed but the one who always gets seen door Zane is Emma. She is the one who saved Zane, she is the mermaid that Zane saw twice (during his saving and with her red hair) and in the finale she told dr. Denman to go home pagina while Cleo and Rikki just walked away.
Season 2: Cleo
This is not rocket science. The main villain of this season existed door the cause of the love driehoek between Cleo, Lewis and Charlotte. Cleo was also the one who first discovered her advanced power and the first to control it. She is the first one to get attacked door Charlotte. In fact, she is the one who drives charlotte insane to the point where she wants to take the trio's power; just for revenge!
Season 3: Rikki
This is just pointing out the obvious but Rikki is the one that season 3 is about. She is the only mermaid who has a obvious connection to the Moon Pool and the strange happenings. She is also the first one to get taken door the water tentacle. She is the first one to gain the water tentacle's trust.

So tell me: what is your opinion about this? Do u think it's just a coincidence? Sound off in a commentaar of commentaren below.
