So was Evie right to be worried about Lyla?

I think that the times that Lyla would grab his hands (hand holding), Zac should have pulled his hands back and made it clear that it's not appropriate since he's got a girlfriend AND he doesn't feel that way about her (perhaps even explaining that it's a sign of affection/etc in case she doesn't realize what she's doing).

Zac should have made it clear that he's got something going on that they (Lyla and the others) are familiar with but that he doesn't want to discuss just yet and that there is nothing romantic (or otherwise) going on with any of them. In fact, should have even had the other two (Nixie and Sirena) confirm to Evie that there's nothing romantic going on between Zac and Lyla and that what Zac said is correct (they're familiar with something and don't want to discuss it). Make it sound like they are sort of a support group.

There are a lot of things about this show that don't add up. This being one of them. They don't get explained and we just accept it and move on. I hope they fix that with S2. That's why even tho I like the show H2O is still better coz they didn't leave us wondering like this.

The thing that I never got was that Zac told Cam but not Evie which and his not being honest with her feed into her suspicions.
