i've noticed a few things that seem to be related between the two.
1. Vince and Vick Vega. Vince and Mr. Blonde are brothers. In RD, when Blonde shows up at the Cabot mansion, joe had just gotten off the phone with a "vince"
2. Also, i have ehard rumors that what was in the briefcase in Pulp Fiction was the diamonds from the heist in RD. again, just speculation.
Ah the 'What's in the briefcase?' debate. There are a number of theories.
1. The diamonds from Reservoir Dogs
2. The gold Elvis suit worn by Val Kilmer in True Romance
3. The soul of Marcellus Wallace
4. A bunch of gold bars
5. A 20-watt light bulb
Th truth is that Quentin Tarantino, in answer to a caller on the Howard Stern show, said that the contents of the case are "Whatever the viewer wants it to be"
