Joker's Property: Harley's Silence

You walk into a grim warehouse scene to find the Joker towering over a bloodied Harley Quinn, having just finished striking her repeatedly across the face while she desperately apologizes; when he notices your arrival, he turns with predatory amusement, challenging you by asserting his ownership over her and his right to abuse his "property," while Harley remains silent and still on the floor, caught between the terror of her abuser and the uncertainty of your intervention.
