I’m sorry sir, but you are probably wrong about this.
A.) Jules said that he would return the case before he told Marcellus he was quitting. Now though something could have happened to Jules after the diner scene, we don’t know the movie ended. But knowing of Jules new found spirituality and good nature we can be assured that Jules returned the case before he left. But since we can’t be sure of that I have more justifiable reasons. B.) If Jules had not returned the case at the end of Pulp and Marcellus decided to get them back, why would they need to rob a diamond whole saler to get Marcellus’ diamonds back? They wouldn’t, because Joe stated in the Mr. White back story that they were stealing “uncut stones from israel” that they were to be picked up the next day. Doesn’t sound like Marcellus’ case. C.) Also if Jimmy is Brown and The Wolf is White, how come neither one of them is the same character they played in Pulp? Most likely the other four colors would not know them and if not by name definelty by face. Where’s the Wolf’s moustache and faster talking banter and how come Jimmy has become a witty analyist of pop culture, when in Pulp he’s a neurotic family man. Also, why would Marcellus choose Jimmy of all people to work with the wolf, they met one morning for less than an hour, and even more why would Jimmy choose to do the job, maybe there is money envolved, we don’t know, but the Bonny Situation infers that Jimmy has given up most crime to keep is wife happy, so unless the pay was of an orgasmic number I don’t see Jimmy taking part in the heist. And why would The Wolf, a problem solver, be asked to rob the diamonds, I’m sure Marcellus has other goons besides Vincent, Jules, and Winston Wolf. My own personal rationale for the contents of the briefcase are that the only person who knows what’s in that briefcase is Quentin Tarantino. And he probably doesn’t know what’s in it, just a cool picture I guess. To retort on your message bluntly, no Jimmy and The Wolf had absolutely nothing to do with Resevoir Dogs, nor did Marcellus or his briefcase.
(On a side note, Joe and Mr. White do speak of a Marcellus in White’s back story. But he sounds like an illegal transporter not a mob boss, he is supposed to be doing “quater and some change in Quentin”(Don’t hold me to that Quentin quote I’m not one hundred percent on it). It’s just another name that QT uses multiple times, such as there being two Floyds in True Romanc(Brad Pitt & Laurence Mason)Or Scagnetti being the last name of Blondes’ parole officer and the last name of the detective from Natural Born Killers. And there being both a Marvin in Pulp(Phil Lamar) and a Marvin in TR(Kevin Corrigan)) Ã‚Â Ã‚Â
