How we cite our quotes: All quotations are from Pulp Fiction.
Quote #1
BRETT: I just want you to know how sorry we are about how f***ed up things got between us and Mr. Wallace. When we entered into this thing, we only had the best intentions. […]
JULES: What does Marsellus Wallace look like? […] Does he look like a b****?!
BRETT: No.
JULES: Then why did you try to f*** 'im like a b****?!
BRETT: I didn't.
If you're a gang boss, you have to make an example of people who try to betray you. For all we know, Brett was telling the truth but, honestly, it doesn't matter, not to Jules or Vincent, and definitely not to Marsellus. No briefcase means no loyalty and if you're not loyal to Marsellus then you are a dead man.
Quote #2
MIA: Besides, it's more exciting when you don't have permission.
Vincent wants to talk ask Mia about the foot massage incident but he doesn't want to offend her. We think his reluctance is warranted; it's a touchy subject. But Mia's comment might be about more than just their conversation. The date could be a test of Vincent's loyalty, and suggestive remarks like this aren't making it any easier.
Quote #3
VINCENT: You see, this is a moral test of one's self; whether or not you can maintain loyalty. Because being loyal is very important.
"Very important" in the sense that you'll get killed otherwise. Even now that he knows the foot massage story wasn't true, Vincent knows he should keep his hands off Mia and gives himself a talking-to in the bathroom. Do you think Mia is testing him or does she really fall for him?
