Oh... now I get it. Here's a better backstory:

Zero ends up bankrupt after Lifty and Shifty steal all his stuff. So he goes mining to make a living. Maybe the upcoming episode could feature Lifty and Shifty getting their comeuppance from Zero.

P.S.: I don't think Todd should be Zero. His personality just isn't suited.
