Q: In one of the more famous Pulp Fiction scenes, Jules and Vincent are eating at a diner when Ringo and Honey Bunny decide to rob it. Their attempt doesn't go well. At one point, Jules tells Ringo to open up his wallet and take out $1,500. http://www.youtube.com/watch?v=3PeyiU3uWJ8&t=1m22s Now, I ain't giving it to him, Vincent. I'm buying something for my money. Wanna know what I'm buying, Ringo? "What?" "Your life. I'm giving you that money so I don't have to kill yo' ass." What does giving Ringo $1,500 have to do with not killing him?

A: Why did Jules have to give Ringo $1,500?

Q: In season one, episode four of True Detective ("Who Goes There") Rust is in a housing project with the Iron Crusaders raiding a stash house. Someone throws a rock through the window and Lamar (the man in the backwards ball cap) taunts one of the bikers, "you sorry yet motherfucker? I told your cracker ass, bitch ass..." and before he finishes he's pistol whipped and shot. Rust immediately realizes the situation is heading south a lot faster than he had anticipated. Another biker smashes another window with his shotgun and begins to fire on the other gang members assembled outside. Rust somehow senses a shot is coming and ducks into the corner right before a bullet comes through the wall. My question is, how did he know the shot was coming right there? Is there someone aiming a gun out of focus that we can't see or was he just playing it safe and ended up being right?

A:
How did Rust know the shot was coming right there in True Detective S1E4?
