After arriving at the farm, Pam and Kirk search for an old swimming hole--Kirk hears a generator and believes he can find some gasoline. He enters the house hoping to find the owner. Unfortunately, this is the home of the hitchhiker, as well as Leatherface, who has some surprises for the travellers consisting of sledgehammers, chainsaws, and assorted cutlery.

Question: What happens to the guy in the yellow shirt, who hits Leatherface in the face with the wrench? The main character leaves with the guy in the truck but the yellow shirt guy doesn't. And we don't see him get killed, it just goes to Leatherface doing his dance. Are we supposed to assume that he dies?
Answer: The yellow shirt guy keeps running off screen while the main character jumps into the back of the truck. Since Leatherface's attention was solely on her, it's assumed the guy survives seeing as no one left in the Family is in pursuit.
