Drastic measures it is. You pick up two large frying pans and start clanging them together like a maniac. Silv curses you out from the other side of the room, but you keep going until Kiera starts to stir.

"Buhh?" she says eloquently. "What happened?"

You kindly inform her that Mr. Grizz has been obliterated into tiny little pieces.

"Aw, what?" she asks. "Who's gonna sign my paychecks?"

"Hang on," you hear Silv call from across the room. "You get paid?"

Kiera blanches. "Uh..." she says. She drops her head back down onto the floor and immediately pretends to fall back asleep. Silv is angrily trying to wake her back up now, but shes not budging.

Go to the security room. Maybe you can check out the footage.
Go to the kitchen to find Ben.
