You were walking home at night from work, the time being 6:00 where crime is active, a robber notices you. Crossing the street he smiles and pulls out a gun at you. You were about to defend yourself until a lady behind you pushes you out the way and with her Super-Sonic scream knocks out the robber. She then looks back at you & smiles.

B-C: "Sorry for pushing you, had to kick in and help. Who are you?"
