You don't hesitate. There's been too much violence and weirdness already. When she's in arm's reach, you lash out with a punch that sends her crumpled body to the floor. When she lands, she goes face first, and one of the two impacts has broken her nose. Blood spatters across the floor and speckles the tips of your shoes.
"Jesus," you say quietly. "What the fuck is going on?"
You aren't sure how long she'll be out. You're not a fighter. This isn't your bag. You have to do something quick.
