Right. She had thought that at most it might ask for a snack of some sort. It was hard to trust anything in this place, and less so magic talking fish but she had offered and she intended to make good on that.

"Let me warm up my own hand first, alright?" Giving the fish a nod she switched the quartz to a different wrist before pulling her wand from her pocket. She held the opposite bare-wristed hand out at arm's length and took aim. A rush of hot air streamed from the tip of her wand, warming her hand as a top-of-the-line hairdryer might. After about half a minute she dispelled the charm and pocketed her wand, giving her fingers an experimental wiggle before looking down at the fish again.

"I hope this is alright," she began gently, leaning over to do as the carp asked and carefully pick the ice off of the surface of the water. "There's a fair bit of ice, I wanted to have some warmth left for your water." Carefully, but with all the daring, nerve, and chivalry that was a common conversational topic of magical hats back in her own world Lily held her breath and let her hand slip beneath the surface of the water.
