For a moment, Elsa is tempted to do one of two things: to hide or to make a wolf of snow. She doesn't want to risk bringing a snow-wolf to life, though, still not entirely sure she won't animate something on accident. She hadn't counted on Olaf being alive, after all. But then, she hadn't been paying much attention when she made him.

But the man doesn't seem frightened or alarmed, just curious. If she's slightly anxious at being caught out practicing, she's also not too worried that he's going to try to hurt her.

"Not at all," she says. "It's fine. It is magic, yes. The only kind I can do." Other people have all kinds of powers, and Lila can do all sorts of amazing things with elements. In a lot of ways, though, Elsa is grateful that she only has the one.
