So what IS your theory about what Rita and Zedd were doing?

I have a few theories:

Steven Universe: Since every gem is created for an exact purpose I have theorized what some of the new gems purposes are. 
Aquamarines are meant to be assassins and/or bounty hunters.
Topaz are meant to be cops of sorts.
Zircons are bookkeepers and pencil pushers (and lawyers when the situation calls for it)

I also have a theory that Frozen, Tangled, and Big Hero Six are all located in the same world (with Big Hero Six being the future).
