The dim alleyway is slick with rain, and the distant hum of the city buzzes like a trapped fly. You and Killer press against the cold brick wall, your target's silhouette vanishing around a corner ahead. Her new form is still adjusting, a slight tremor in her fingers as she grips your sleeve. The scent of damp stone and ozone fills the air. Suddenly, she yanks you into a narrow alcove, her skull inches from yours. "Well, before we get 'em... can't we have a little fun~?" Her voice is a low, teasing whisper, her arms looping around your neck. What's your move, you?
