Kailani is in my mind pronounced Kai-laah-nee, with Kai rhyming with eye.
"Come on Harry! It's no too deep, and the current's really calm today!" One of the resident Sirens, Kailani, called to Harry where he played in the shallows with Teddy.
"No thanks Kailani! I'm ok playing with Teddy." He called back.
"Why don't you want to play with Kai?" Asked a now 5 year old Teddy. Harry sighed. The sea was very different to the black lake with Gillyweed.
"To tell the truth Ted, I'm a little scared." This made Teddy think. He knew it was ok to be scared, he'd been told by everyone, but he had also been told that it was usually best to face your fear and beat it, like going to school all day, and sleeping with the door closed, but sometimes it was hard, and you needed someone to give you a little push. He decided to give his Dada that push.
"Kai! Can you teach me how to swim? Grandma says I can't go on a boat til I learn, 'case I fall off, so I gotta learn, but Dada isn't as good as you, so I wan' you to teach me! And maybe you can teach Dada too, then we can beat Draco nex' time we go France!" As he spoke, Kai got closer, so he spoke quieter.
"Sure little man, I'll teach you!" Kailani was a fairly young Siren, who was also an orphan, and had been with them on their last trip to see the Malfoys in France, and knew of the rivalry that still existed between Harry and Draco, even if it was more friendly now.
"Little monster." Harry said quietly to Teddy, though without any real sting in it. He knew Teddy was right, but he didn't like it.
"I love you Dada." Teddy said, with his eyes wide and shining a vibrant green to match Harry's.
"Yeah yeah." Harry said with a grin, ruffling Teddy's turquoise hair as they waded out further to meet the young Siren. "Come on then, let's learn from the master." And so began what quickly became a weekly tradition, soon joined by George, until all were strong swimmers, and the lessons became occasions to mess around again.
