"What's "normal" mean?"

"Like, follow the laws of physics."

"I don't think hair normally stays still."

"I don't mean the air, I mean the objects. Like if you make an illusion of a ball will it act like a ball, and stuff."

"Only if I tell it to."

"Do you have to tell it all the time, or just once?"

"Just once, unless I want to change the way it moves or whatever."

"Oh. The stuff I make always acts normal."

"Hmm, show me the coolest thing you can do."

"I dunno what that is."

"Okay, try using your powers to do something cool."

"Iunno what counts."

"Whatever you think is cool." He smiles.

"I'm not exactly in a mood that helps me think of cool things."

"Hmm, maybe I could go first?"

"Okay."

Maurice's skin and hair returns to its original colouration, and his boat disappears from under him. 

And then the kids further out are attacked by yodelling Valkyries.

"What."

"They're just solid enough to be startling." 

"Okay... Can you think about cool things that don't involve violence."

The Valkyries vanish, and are replaced by a classical looking flying saucer above the two boys' heads. 

Just how big is this flying saucer?

Twenty meters across.

"Okay this is cool."

A theremin tune plays.
