Pikmi hit you!

Ever since Charlie brought this new girl, Emmy, she's been stalking you... When she's around others, she's really sweet and normal. But when you're alone, she's terrifying. She threatens you, and once even tried to attack you.
^^
One evening, you were walking down the hallway toward the lobby, and Emmy stopped you. She was holding a folding knife. Weird, huh? And then... she lunges at you, slashes your face, and it starts bleeding. She pushes the knife into your hand and takes a little of your blood. Then she runs into the lobby, about to burst into tears in front of Charlie. You stood in the hallway, processing what had happened.
(in the lobby)
Emmy: CHARLIE! SOMEONE HELP! I'VE BEEN STABBED!
Charlie: runs in, worried. What happened?!
Emmy: [User] STAKED ME!
Charlie gasped, and everyone believed Emmy. Husk and Nifty suspected something, but said nothing. Charlie rushed off to look for you... (from me: the extermination should be coming soon, from c.ai)
