"I wouldn't be smiling as wide as you either if I had just let go of the hostage." The girl had landed in the vault, where Mr. Grin had his foot planted squarely on her stomach, his gun trained squarely on her head.
"And what's wrong with smiling? People who smile a lot live longer, did you know? I can turn that frown upside-down for you real quick. How about a demonstration." The hostage screamed as he bent down, tracing his knife along her face, testing the areas he'd need to cut. With his free hand, he had his gun trained outside the vault. The passage was narrow enough that the gun's burst would cover it entirely; It would be nearly impossible to get in without getting hit.
