Finally, to make sure that Twilight had a concept of the range of a gun, he drew a quick sketch of the room, marking off the distance between her and the door with a single hash mark. Next, he pointed to the dotted line between the barrel and the bullet, and began filling in dozens of hash marks, remembering as he drew that the ponies crossed them off in sixes, rather than fives. He didn’t count how many he used, so he was probably over-estimating the range of the pistol, but it was better to be safe than sorry.
