Rotten Immortal (3)

I am not sure where it came from, but I found this arrow laying by my foot. 

Suddenly, I heard a sharp scream behind me: "Sorry 'bout that! Did it hurt you?" 

I didn't exactly understand what he was saying; it was as if I heard him through a watery veil. He was now running towards me, a bow and arrow in hand and wearing some sort of weird ultramarine uniform; I didn't recognize him either. Where the hell was he coming from?

Once he was at arm-length of me, I gave him back his glistening arrow but he refused to take it back. It was then that I noticed the wood from the arrow's body had been stained red, a bloody red. 

"Are you sure you're okay?!" he continued, seemingly anxious, "You look hurt…".
