Alexander
And now the fun part began as everybody else started to take the jump one by one. First was Katarina, who made the jump easy enough, but missed her timing and started to slip the same way he had. He'd been prepared for something like this however, and quick as a whip he reached out and grabbed her by the arm to pull her back up. "No problem," he told her in response to her gratitude, "You'll have to teach me how to swim first."
Next came Astrid, who needed no assistance whatsoever. She actually moved quite comfortably, like somebody who was used to crossing the empty air. I wonder where she got that from, he absentmindedly wondered as the group continued. Sumi proved similarly able, in spite of her all sugar diet, but by this point he'd learned it was better to simply avoid questioning such things when it came to her. It wouldn't make any sense anyway.
Christopher and Kade were where the trouble started. Christopher slipped completely, and this time Alexander was too far away to reach out and grab him. with nothing else to try he whistled again, and to his amazement the wind answered him again and lightly tossed the other boy back onto safer ground. He was a little more calm when Kade nearly fell off; maybe it was the fact that he'd done it three times now, or perhaps something else, but he whistled much more casually to help the groundskeeper up with the air.
"I don't know how I'm getting used to that," he said out loud, "This is really bizarre..."
After that, he could only watch as Astrid did her work.
