Go down the alley

As you head down the alley you see a women being fighting another women. Both of them are fighting over a box. The box was green and shinny with a wired glow.
Then you see both women hit each other on the head at the exact time, nocking them both out. You walk over to them and say "Are you both O.K.?". None of them answer so you stop bodering.
You lean down to look at the box laying in the floor and try to think what to do. You decide to leave, but then what about the box?
