"Oh, but look, look, the moon shards can't hurt me!" Jack swipes his tails excitedly across the air, and they trail blue-white fire behind them. A metal shard that fell from the clouds above meets the fire and disappears. "See? The fire makes it safe! It's not real fire, it doesn't burn at all, I think it's mostly illusion, but it protects."

He sounds inordinately proud of that. Jack has never really protected anyone before, not even himself. It's novel.
