1))As far as Pulp Fiction goes, Marsellus has a bandage on the back of his neck because, if you read the Christian bible, the devil will take your soul from the back of the neck. Marsellus sends Jules and Vincent to recover his soul (the righteous helpers) from the goons in the apartment (the devils helpers). the combination on the briefcase is 666, and when the case is opened, the golden glow is the beautiful luminescence of the soul of Marsellus, hence everyone being mezmerised by the sight of it or saying "its beautiful......"(Pumpkin), because whats more beautiful than the human soul right? So when Jules says his Ezekiel 25:13 quote and clips Brad, the last goon hiding in the bathroom comes out blasting. But alas!! divine intervention occurs (although if you look carefully at the wall before the shooting starts you'll notice that the holes are already there[a film slip?]) and Jules and Vincent are saved. Jules "sees the light" and retires, but Vincent denies it and dies at the hands of Butch later the next few days. --2)) Butch keyed Vincents car. If you remember the bar scene where Vega is eyeing up Butch calling him Palooka and Punchy, Butch is giving Mr. Vega the "im gonna whip your ass" look but doesnt when the realization comes that Vega and Wallace are good friends. So what does Butch do? After he buys his pack of Red Apples he goes outside and keys Vince's Malibu. So how does Butch know that the red Malibu is Vincents? My guess is that there are no cars parked outside the alleyway entrance to the bar and since there were only Wallace, the bartender, Jules, Vincent , and himself, Butch assumes.
