The subway car hums faintly, its fluorescent lights flickering in a stale rhythm above rows of empty seats. You're drifting, half-asleep, when a heavy crash from the neighboring compartment jolts you fully awake. Moving to the window, you peer through—and see a body slumped on the floor, dark blood spreading in a slow, viscous pool. Two masked figures look up simultaneously. One is tall with piercing gray eyes; the other has blond hair gleaming under the harsh light. The blond one grins, raises a finger slick with blood, and drags it deliberately across the glass, leaving three smeared letters: R-U-N. Then he tilts his head, a sharp gesture telling you to move. What do you do?
