Was the gimp a prisoner?
Was the gimp an actual prisoner of Zed's gang or was he just someone who they kept around for 'odd scenarios'?
Until recently, I always figured 'the gimp' was some part of the gang, a kind of S+M pervert they 'brought out' when it came time to torture a prisoner. Basically he was a willing participant.
However, recently I read another interpretation that the gimp was a prisoner Zed liked to torture and who, had all things gone to plan, was probably going to be killed during this scene and replaced with Butch/Marselis as the 'the new gimps'.
Hence the the shot where the gimp points at Butch and then himself. My initial interpretation of this gesture being that the gimp was going to 'have' Butch, but now I think it meant that the gimp was welcoming his own death and that Butch was going to replace the gimp.
