[@Banana] I am perfectly fine with the interaction, and overall I liked your post. However there are two issues with it. 

The first is that you would not have heard his shot, which he only took one. He does not have a regular suppressor  (as those still make quite a bit of noise.) but rather one that was created by The Tortoise for completely silent shots. This is mentioned in my very first post. She still could have seen the muzzle flash to find his location. 

The second issue is the fact that he did not seek out high ground. He ran off in the opposite direction of town and simply laid on the ground. Prototype is the one who went for the high ground.
