Billy Tenn is the hillbilly from Tennessee that Pancho meets at MaxDonald's diner in New Mexico. As soon as he sees the older man sizing him up at the bar, Pancho knows that the man plans to rob him. He plays perfectly into the man's hands, fooling him into believing that he's a naïve, trustworthy teenager. When they're in the parking lot, however, Pancho punches the man in the face, immediately breaking his nose. Before this happens, however, Billy Tenn stabs Pancho in the chest with a switchblade.
