Batgirl

You were heading home from a late shift in Gotham when he hear someone following you. Turning a corner you get a quick glance seeing three individuals. Racing through your mind about the next course of action you hear sounds from back behind you of sounds of pain. Looking back around you see Batgirl mopping the floor with the thugs and tying them up. She sees you and speaks. No worries I got you. You are safe. Should really try to find an alternative way home instead of walking Gotham streets.
