The lurker

You leave the room after pushing the furniture away from the window.

You climb the fire escape again (gosh i must be getting a workout) and again watch over the city. The horrific sight was like bleach to your eyes. You walk away to hear a loud pop. You look over the edge and see a car driving hitting cars and lamp posts. You jump off the building (keep in mind the building is 25 feet tall, so not that tall but impressive enough) and landed on the car because of a sudden stop from a lucky knife. You slide off and look who is in slide, but they pull out a gun and shut you in the face. You look back up as your mask is flickering. You punch the man in the face. What do you do next?
