The man's non-answer was answer enough for Falis, which made her a bit concerned, if only because this man was a friend of Ami's. She didn't let any of that concern show, though.

"I don't doubt it," she replied, tapping again. "Sounds about a foot thick, give an inch or two." She narrowed her eyes at the ice. "I can probably break through it, but I'll tear my shoulder doing so thanks to the fucking ice. It might cause some... not good consequences." She was well aware of how much pain that would cause and how quickly her other side would start to pressure her into letting it loose. She would not let it loose. She might not care about accidentally killing the old man, but she'd be fucking pissed if she killed Ami because she lost control.

"You got any punch left in you?" Falis stopped at a point she thought was weaker than the rest.
