You were one of the last sirens. Zane was your enemy he always bullied you. One day you saved him when he almost drowned near Mako island and laid him on the shore waiting for him to wake up

Once he woke up he looked around and started asking things like how did it happen? Or anything like that

He kept asking questions then he realized there was no boat around on the shore. He walked towards you very close to the water

"If there's no boat, how did you get me on the shore?"
