Ok. This is a question I have been giving lots of thought into. Mr. Purple and the other Mr. Color codename guy. What if Mr. Purple and Mr. Black or whatever color codename would be Jules and Vincent?
In the beginning Joe tells Mr. Pink that there already is a Mr. Purple doing another job. What if that's Jules or Vince? Or they had other codename?
If its not them, then any speculations on who Mr. Purple and/or other guys are? And where they are when Reservoir Dogs is happening?
