The ability

At the moment of Emily was a frantic in search for stock. 

Men's voices were moving away. 

That means every step they take away from Emily, means she can't go after them.

  If she was going to hit them, she really had to do it from the first moment she got to the battle scene.

Now they look like the rats that escaped into the woods. Strangely, anger blinded Emily from all those facts. 

It was driven by something other than logic and reason.

It was driven by anger for love.

Emily finally found something that might work. She found four arrows of arrows.

Emily looked at the four arrows and then looked at the bow. 

How can she use them now that the idiots are gone?

  It was one of the crazy naive ideas Emily thought of.

She thought she'd climb the tree in order to get a wider field of view.

A field of vision that can see men on the run.
