Okay, Ed fell at the top of the cliff and was injured by one of his own arrows. The hillbilly had a gun. Somebody shot the hillbilly from the back. Lewis, the only other archer we know of, is injured, at the base of the cliff. So, who shot the hillbilly? Or did I miss something?
shareThe arrow clearly went through the front and out the back. You can see the arrow head pointing out through the hillbilly's back when he falls dead. You can also see the back "feather" part of the arrow sticking out the front when Drew is checking his teeth. Pay better attention.
As for Drew, he didn't shoot himself with an arrow. He shot the hillbilly and then fell on another arrow on his person. Only the doctor assumed he shot himself and Drew didn't correct him. Again, pay better attention.
